Autores: Audouin, Jacques.
Plusieurs auteurs, en particulier Faideau, Bluteau, Lambert, Dubreuil, etc... ont déjà donné de nombreux détails sur la mytiliculture et sur les bouchots à moules de la Baie de l'Aiguillon. Afin que cette note donne une vue d'ensemble sur la mytiliculture, nous avons été amenés à reprendre et à résumer les données exposées par eux. Nous avons, en outre, ajouté certains détails de la technique employée par les boucholeurs. Nous nous sommes efforcés d'apprécier l'évolution qui s'est manifestée depuis une trentaine d'années. Cette étude comprend deux parties principales : Origine et forme des bouchot - Mode d'exploitation.

Importance de l'oxygène dissous dans l'eau des bassins ostréicoles
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Ladouce, Rémy; Le Dantec, Jean.
On constate souvent, surtout l'été, une mortalité anormale des huîtres dans les bassins, claires, dégorgeoirs ou dépôts, dont l'eau n'est renouvelée qu'à intervalles assez longs. Les ostréiculteurs ont l'habitude d'incriminer uniquement la chaleur, mais les essais de M. BOURY, en 1927, et de l'un de nous, en 19536, montrent qu'en définitive cette mortalité est provoquée, en grande partie, par le manque d'oxygène.

Travaux ISTPM 1954 - La pêche aux Antilles Françaises
Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
A head of laboratory from the Biology Service has been entitled by the management committee of the F.I.D.O.M. to study the fishing opportunities offered in the waters of the French Caribbean, from November 1950 to May 1951. The aim of this mission was double: - on the one hand, it aimed to determine if the fauna and the geographic data of these islands were sufficient to allow the development of the fishing industry, and consequently the feeding of more than half a million individuals; - on the other hand, it aimed to try and orientate some of the large Caribbean manpower towards this new industry and to drive the existing artisanal fishermen towards a gradual modernisation of their living and working conditions through a technical education.

Provedor de dados: Institutional Archive of Ifreme (ArchiMer)
Autores: Bouxin, H.
Durant sept années, de 1933 à la guerre, j'ai observé dans la région de Concarneau (Finistère) le frai de diverses espèces de Lamellibranches marins, notamment de la moule commune, Mytilus edulis var. galloprovincialis (Lmk). Les travaux sur le frai de la moule sont extrêmement nombreux. Les auteurs qui s'en sont occupés n'ont pas eu, en général, la possibilité d'observer les émissions elle-mêmes. Ils ont dû se contenter d'en induire l'époque soit d'après l'état des glandes génitales, soit en observant la présence de larves dans le plankton, soit, enfin, d'après la possibilité de fécondations artificielles. Or, si utiles que soient des observations de ce genre, elles ne permettent d'atteindre qu'à une probabilité de circonscrire qu'une époque relativement...

Dès sa création, l'Office des Pêches Maritimes s'est attaché à l'étude de la biologie du Hareng et des études analogues ayant été poursuivies dans les laboratoires étrangers, l'idée des grandes migrations du Hareng - idée longtemps familière aux pêcheurs - avait été abandonnée pour faire place à la notion des races diverses définies par un certain nombre de caractères morphologiques et biologiques en rapport avec le milieu; en même temps, la notion de migrations localisées à l'intérieur de l'aire d'extension de chacune de ces races s'imposait et était finalement confirmée par des expériences de marquages.

Il fut également membre de l'Académie de Médicine et professeur au Muséum puis au Collège de France; il fonda le laboratoire de zoologie et physiologie maritimes de Concarneau et en fut le premier directeur. En 1892, il se vit confier la charge d'inspecteur général de la pêche fluviale et de la pêche côtière maritime. Dans le domaine qui nous intéresse particulièrement, l'ouvrage de Coste le plus fréquemment cité est le récit commenté et accompagné de suggestions qui porte sur tire : "Voyage d'exploration sur le...

Etude sur la reproduction de l'huître plate Ostrea edulis dans les claires de la région de Marennes-Oléron

Autores: Trochon, Pierre.
Les claires situées sur les deux rives de la Seudre, sur les côtes de Marennes, du Chapus et de l'Ile d'Oléron, sont des bassins creusés dans des terrains argileux. Elles sont alimentées en eau de mer par un système de chenaux et de ruissons, leurs affluents, pour un coefficient de marée en général égal ou supérieur à 70. Dans certaines claires, les ostréiculteurs déposent, au mois de Mai, des huîtres plates originaires de Bretagne ou d'Arcachon, âgées de trois ou quatre ans, à raison de 2, 3 et 4 huîtres par mètre carré. Dans ce milieu, sous quarante centimètres d'eau, elles vont pendant six ou sept mois, croître, engraisser et verdir.

Caenis Demoulini, a new Ephemeropteron from Thailand
Provedor de dados: Naturalis Digital Academic Repository
Autores: Bruggen, A.C. van.
During a short stay at Bangkok on December 3rd, 1953, Professor H. Boschma observed that enormous quantities of minute insects were attracted by lamplight in the hotel of the Royal Dutch Airlines (K.L.M.) "Plaswijk" at the airport Laksi. From the enormous accumulations of these insects around the lamps he collected a sample which he entrusted to me for examination. This sample proved to consist almost entirely of a new species of mayfly which is described in the present paper. Caenis demoulini nov. spec. Female imago. Head and thorax uniformly yellowish brown. Eyes purple-black, prominent. Antennae grey-brown ; median ocellus prominent, colour light brown with a darker edge.

The environment of the Dutch Wadden Sea, as well as that of the estuaries in the southwestern part of the Netherlands can be divided into three sub-zones: (1) the channel floors (sensu lato), i.e. the areas below mean low tide level, (2) the tidal flats (sensu stricto), between the levels of mean low and mean high water and, (3) the salt marshes, above the level of mean high tide. The channel floors are composed, either of older sediments, which have been laid bare by erosion of the tidal currents, or by new deposits, formed in the channels themselves. The latter are predominantly of sandy character, but may show locally high contents of muddy material, especially in sheltered bays. The tidal flats consist for the greater part of sand. Slightly...

Pleistocene vertebrates from Celebes : XI. Molars and a tusked mandible of Archidiskodon celebensis Hooijer
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hooijer, D.A.
The species mentioned in the title of the present contribution was first described on the base of two incomplete upper molars, some fragments, and two portions of limb bones (Hooijer, 1949). The two and only complete molars were described later (Hooijer, 1953a). To this has been added the description of the milk dentition and of three premolars (Hooijer, 1953c). There are, however, important lacunae in our knowledge of the molar dentition to be filled. It remains as yet uncertain whether the type upper molar of 1949 represents M2 or M3, while the smaller of the complete lower molars of 1953 could be either M1 or M2. The prolonged study of the fragmentary molars in the Celebes collection has now made it possible to assemble the full set of upper and lower...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Stock, J.H.
Les Copépodes commensaux et parasites d’Invertébrés, quoique très communs dans toutes les mers, sont peu connus. En vérité, on en a décrit un nombre assez grand de genres et d’espèces, mais les descriptions sont trop souvent superficielles, voire même erronnées. Un de ces genres très peu connu est Tococheres, établi par le Professeur Paul Pelseneer, 1929, pour un Copépode trouvé sur les branchies de Loripes lacteus. Bivalve récolté dans l’Aber de Roscoff (Bretagne). La description de Pelseneer ne donne d’informations que sur la forme generale de la femelle, sur les antennules et sur la cinquième paire de pattes. On ne sait absolument rien sur l’antenne, les pièces buccales et les 4 paires antérieures de pattes thoraciques.

OLETHREUTINAE (Eucosmidae auct., Eucosminae auct.) Introduction The study of the South Asiatic representatives of the subfamily Olethreutinae of the Tortricidae is difficult on account of various reasons. Our basic knowledge of this group of insects originates from the knowledge of the Palaearctic fauna; unfortunately the taxonomy, and especially the nomenclature of the European Olethreutinae has for a long time been in a deplorable state of confusion and only recent pioneer work along modern lines, chiefly by Obraztsov, leads to some order. Unavoidably this confusion throws a shadow upon the study of the Olethreutinae from other regions than the Palaearctis. Since genital characters are of cardinal importance for the classification of the genera and...

Observations on the orbital region of the skull of the Mystacoceti
Provedor de dados: Naturalis Digital Academic Repository
Autores: Muller, J.
It is well known that the main functional components of the skull in the Whalebone Whales (Mystacoceti) attain an ultimate size, which is out of normal proportion to the rest of the skeleton as compared to the proportions existing in land-mammals. As generally supposed the aquatic mode of life has greatly influenced the shape of the skull. Therefore, it is to be expected that the various species, which all have the same mode of life, show a certain amount of convergence. However, not all bones have become enlarged to the same degree; e.g., the alisphenoid and the orbitosphenoid have remained relatively small. Apparently these bones of the orbit have not been influenced by the aquatic mode of life to the same extent as is the case with other elements of the...

Mosquitoes of the Netherlands Antilles and their hygienic importance
Provedor de dados: Naturalis Digital Academic Repository
Autores: Kuyp, Edwin van der.
The Netherlands Antilles may be divided into: (1) The Curaçao Group (or Netherlands Leeward Islands): Curaçao, Aruba and Bonaire. (2) The St. Martin Group (or Netherlands Windward Islands): (Netherlands) St. Maarten, Saba and St. Eustatius. The latter islands are very small, forming together only 8.1 per cent of the total area of the Netherlands Antilles, and 2.2 per cent of its population. The Curaçao Group often has a desert-like aspect with a “tropical dry-forest” vegetation. Therefore on these islands the mosquito pest is nothing like so bad as it usually is in the tropics. There are few permanent breeding places, except man-made receptacles in and around the houses to store rainwater or well-water in as the Government waterworks do not always produce...

Hippeococcus : a new genus of Pseudococcidae from Java with peculiar habits
Provedor de dados: Naturalis Digital Academic Repository
Autores: Reyne, A.
In 1950 I received from Mr. D. Hille Ris Lambers a strange Pseudococcid from Java which had been collected by Mr. F. W. Rappard, a senior forestry officer, who regularly collects aphids for Mr. Hille Ris Lambers on his tours of duty. As this insect was a coccid, it was transmitted to me for examination. Its appearance is quite abnormal; the shape of its body reminds one almost of a large mite (fig. 4). The 6-segmented antennae have a dense vestiture of fine hairs, with exception of the 2 first segments which are very short. A tuft of 5 very long setae is present on the top of each of the anal lobes. The ungual digitules are extremely large and very flat. It was only after close study that the insect was recognized as a Pseudococcid. It has 2 pairs of...

С. S. Rafinesque as a carcinologist : an annotated compilation of the information on Crustacea contained in the works of that author
Provedor de dados: Naturalis Digital Academic Repository
Autores: Holthuis, L.B.
I. INTRODUCTION In the last tens of years more and more attention has been paid to the much neglected and ignored publications written by the eccentric early American naturalist Constantine Samuel Rafinesque. Until now, however, Rafinesque's work in the field of carcinology has received but little attention from modern authors. In 1905 Ortmann (1905, p. 107) pointed out that the name Astacus limosus Rafinesque, 1817, is older than the name Astacus affinis Say, 1817, for the same species, and that consequently the former name has to be used. In the same year Richardson (1905, p. 10) replaced the invalid generic name Ligia Fabricius, 1798, by Ligyda Rafinesque, 1815. M. J. Rathbun (1937, p. 63) substituted the generic name Thelxiope Rafinesque, 1814, for the...

Inhibition of the Processes of Growth and Differentiation in the Embryonic Development of the Axolotl (Ambystma mexicanum)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Stolk, Anth.
The problem of the retardation of the processes of growth and differentiation is certainly as important as the processes of growth and differentiation themselves. It is striking, therefore, that whereas the analysis of growth has been carried out for a considerable period of time already, the analysis of inhibition was only commenced a few decades ago. It has to be admitted that Wiesner (1894) succeeded in demonstrating the presence of a substance retarding germination in the slime of the mistletoe (Viscum album), but this remained a solitary observation for some time. About 1920 a series of important publications appeared which deal with inhibiting substances. Oppenheimer (1922) discovered a substance of this kind in the fruit pulp of ripe tomatoes,...

Notes on Dutch Lichens
Provedor de dados: Naturalis Digital Academic Repository
Autores: Maas Geesteranus, R.A.
In Madroño (1936) Herre has lamented the disappearance of lichen species through the disastrous interference of man. Unavoidably, the advance of civilised modern life is linked with destruction of the vegetation. This applies all the more as the endangered area is more densely populated and it certainly applies most alarmingly to the lichen flora of the Netherlands. Here, every way-side tree felled is an irreparable loss to the epiphytic lichen communities, every acre of heath burnt or turned into arable land is a blow to our stock of terrestrial lichen species, whereas the use of dry fertilisers and the spraying of orchards are very effective in killing any lichen in the neighbourhood that otherwise might have survived. A comparison of the material...

While engaged on working out the beautiful pycnogonid material dredged by Dr Th. Mortensen in shallow waters near the Virgin Islands, I thought it useful to compare this dredged material with material collected between the tide marks, or just below the low tide line. So I was very glad to meet Dr P.

From 1915—1918 I stayed in Bandung where I had little opportunity to continue my investigations. From 1918—1932 I lived in Buitenzorg (Bogor) where I could resume my studies on the Loranthaceae, not only as to the germination of the seeds, but also the pollination of the flowers. For this purpose I sowed many species of Loranthaceae on shrubs in the neighbourhood of my home, so that I could easily check the development and had ample material at my disposal. The investigations were hampered by the chaotic conditions of the systematics of the Indomalayan Loranthaceae in...

Autores: Andreas, Che.H.; Prop, N.
A study has been made of the Indo-Malaysian species of Cnestis. The mutual length ratio of sepals and petals, — brevi- and aequipetaly —, is the main differentiating character for the species; there are no transitions. The areas of distribution overlap in the Malay Peninsula (fig. 1); brevipetalous types are known from the Malay Peninsula, Sumatra, Borneo and Celebes, aequipetalous types from Burma, Siam, Indo-China and the Andaman Islands, the Malay Peninsula and the Philippines. Fruits are of two different shapes: beaked in aequipetalae of the Andamans, Burma, Siam, and Indo-China, pear-shaped in remaining aequipetalae and in brevipetalae. Leaves tend to be longer and jugae more numerous in brevipetalae than in aequipetalae. Other characters do not have...

Viele Sammler rümpfen die Nase über die Benennung von Formen.

A redescription of Puto antennatus Sign. (Homoptera, Coccoidea) with notes on Ceroputo pilosellae Šulc and Macrocerococcus superbus Leon.
Provedor de dados: Naturalis Digital Academic Repository
Autores: Reyne, A.
In the taxonomy of Coccoidea or scale insects much confusion is due to an insufficient knowledge of the type species of several genera. Especially our knowledge of some of the older genera is very incomplete, as the descriptions of their type species are extremely short and superficial from the modern point of view. The type specimens, on which the original descriptions of the genera were based, are distributed over several museums in all parts of the world; in some cases type material is no longer in existence, and as far as available it is seldom lent to persons in foreign countries. In consequence of this we have often to rely on the original description, as the type material is not available for examination. Signoret (Essai sur les Cochenilles,...

Autores: Lam, H.J.; Barkman, J.J.; Ooststroom, S.J. van; Soest, J.L. van.
This charming and handy book printed on excellent paper, with its numerous clear pictures of well-known Malayan plants, reminds one in many ways of Merrill’s “Plant Life of the Pacific World” (MacMillan 1946, New York), which has perhaps served Prof. Holttum as an example. Its size being only slightly smaller than Merrill’s book and the area covered being very considerably smaller, its descriptions of plants are naturally more detailed; the more so as only a choice has been made, in which the special interests of the author — ferns, orchids, gingers — are evident though not predominant. The plants described are not regionally arranged. The 17 chapters are rather headed by names of life-forms, striking organs, and special habitats. As is pointed out in the...

Diatoms as a means for identifying the origin of Aquatic plants
Provedor de dados: Naturalis Digital Academic Repository
Autores: Werff, A. van der.
In 1934 Dr van Steenis recorded Elisma natans (L.) Buch. for the first time outside Europe, viz. from Java. This unusual record was based on a single specimen collected in 1932 by Dr A. Kleinhoonte in Central Java at 2000 m altitude on Mt Diëng, now preserved in the Herbarium Bogoriense. Miss Kleinhoonte assumed there was little doubt that she had collected it in Java. After having collected information from the Fisheries Department in Java, that no Elisma was ever planted by that Service, Dr van Steenis stated (1, p. 175): “Though it is a waterplant, I cannot account for this enormous discontinuity.” A year later (2, p. 55) he gave a figure of the specimen and concluded that he felt forced to accept the species as a native of Java. However, he nursed a...

Gids voor de Tentoonstelling West-Indische Dieren
Provedor de dados: Naturalis Digital Academic Repository
Autores: NN.
West-Indië heeft zijn naam te danken aan een vergissing. Een grootse vergissing overigens, want toen Columbus in 1492 Amerika ontdekte, meende hijzelf dat hij de Oostelijke eilanden van de Indische Archipel had gevonden. Het verhaal gaat, dat bij de eerste eilanden die Columbus bezocht, ook St. Maarten was (11 November 1492, d.i. op St. Maarten’s dag). Al gauw moet men hebben bemerkt dat dit nog niet de gezochte (Oost)-Indische eilanden waren. Latere expedities hebben het pogen langs deze weg Oost-Indië te bereiken voortgezet, wat tot gevolg had dat reeds in 1498 het vasteland van Zuid-Amerika (o.a. de monding van de Orinicorivier en Suriname) door Spaanse ontdekkingsreizigers werd betreden. Curaçao werd in 1499 ontdekt door Alonso de Ojeda. Zowel de...

Notes on the Ichthyology of Surinam (Dutch Guiana) 3. A new species and two new subspecies of Nannostomidi from the Surinam river
Provedor de dados: Naturalis Digital Academic Repository
Autores: Hoedeman, J.J.
My previous account on the Nannostomidi (1951, The Amsterdam Naturalist, 1 (1): 11—27) dealt with the synonymy of the recognized species. Diagnoses were given of the three genera, Nannostomus, Poecilobrycon and Nannobrycon (new genus). The account was based on but little material, largely on descriptions in literature, yet it could readily be proved that the species described before belong to 5 species only and to 3 well defined genera. I have since had the opportunity to study rather large series from Surinam and some other localities. An entirely new species was found among this material, which is so interesting in many respects that it induced me to reconsider the matter of the phylogeny of the tribe.

Revision of the genus Chelonocoris miller (Hemiptera, Aradidae)
Provedor de dados: Naturalis Digital Academic Repository
Autores: Usinger, R.L.
Apterous Aradidae were first brought to the attention of Hemipterists by N. C. E. Miller (Ann. Mag. Nat. Hist. [11] 1: 498-510, 1938). In fact it can be said that this paper with its excellent illustrations was the stimulus for the striking discoveries that have been made in this group in the past decade. The genus Chelonocoris Miller was proposed for a group of seven (actually 8 as is shown below) very large species from Malaya, Borneo, and (as it now appears) India. The present paper was prompted by the discovery in various European museums of several additional species which extend the known range of the genus to Java and Sumatra. In order to place these new species a key was prepared. The first key was based on Miller's types and was written while...

Two large specimens of a hitherto unknown species of neotropical catfish have recently been found dead and washed ashore beneath the dike along the Westerscheldt near Biezelinge, Zeeland, at a mutual distance of approximately 300 meters. Both were in excellent condition and have been presented to the Rijksmuseum van Natuurlijke Historie at Leiden by Mr. B. J. J. R. Walrecht. A superficial examination already disclosed the fact that the two specimens belong to the (sub)genus Selenaspis, a well known group of catfishes inhabiting the salt and brackish shores and estuaries of the northern part of the South American continent. Some of the species are known to spawn in fresh water. The present specimens must have been transported by ship. Whether they have been...

On the determination of pyroxenes by X-ray powder diagrams
Provedor de dados: Naturalis Digital Academic Repository
Autores: Zwaan, P.C.
The X-ray powder method for determining minerals has been applied to the important rock-forming mineral group of the pyroxenes in this thesis. The purpose of the investigation was to seek the relationship between the variations of the intensities and positions of the reflections in the powder diagram and the variations in optical properties and chemical composition. For that purpose a number of pyroxenes from different localities were investigated optically, chemically and röntgenographically. The orthopyroxenes. — The optical examination of the orthopyroxenes indicates, that the variation of the optical properties is related to the chemical composition (see Table 1). A difference between plutonic and volcanic orthopyroxenes lies in the size of the optic...

The collections of Dermaptera in the Rijksmuseum van Natuurlijke Historie at Leiden and the Zoölogisch Museum at Amsterdam, referred to in the present paper as "Museum Leiden" and "Museum Amsterdam", consist of numerous specimens including many types described by previous authors and a fairly large number of hitherto unidentified examples. A reinvestigation and an identification of the unidentified material therefore promised interesting results, a promise which has been fulfilled. The investigations took place during the war years 1942 and 1943 under unfavorable circumstances. The original MS was finished shortly after the war but, due to printing difficulties, publication had to be postponed. During the recent preparation of the present paper, some...

Provedor de dados: Naturalis Digital Academic Repository
Autores: Laidlaw, F.F.
Dr. E. Jacobson spent some months on the island of Simalur, and on some of the smaller islands in its immediate neighbourhood in the course of the year 1913. He made extensive zoological collections on these islands, whose fauna was very little known up till that time. Amongst his material was a series of shells belonging to the Pleurodontid genus Amphidromus. This series has been entrusted to me by Dr. Van Regieren Altena, and I am grateful to him for the chance of seeing these very interesting shells, and for the help he has given me in dealing with them. I have too to thank Mr. G. L. Wilkins for the figures. Simalur is the most northerly of the long chain of large islands which lie along the West coast of Sumatra.

Geology of the border region between Coahuila and Zacatecas, Mexico
Provedor de dados: Naturalis Digital Academic Repository
Autores: Vloten, Roger van.
The border region between Coahuila and Zacatecas is part of the mountainous country south of Parras in northeastern Mexico. It includes a thickness of about 2,600 meters of Jurassic and Cretaceous rocks that were deposited along the northern border of the Mexican geosyncline along the southern margin of the Coahuila Peninsula massif. During early Tertiary time these sediments were compressed into folds parallel to the borders of the massif. The majority of the anticlines in the area mapped is overturned to the north. After the compressive stage a tensional stage developed and a system of tensional faults was formed. Block faulting found place on a large scale. A suggestion by de Sitter that some longitudinal faults may be comparable to schistosity planes...

The Conference of Brussels, called in 1853, was the first International Maritime Conference ever held. It sponsored the idea that governments should foster systematic weather observations on ships, and should prepare and publish charts of the prevailing winds, ocean currents, average sea and air temperatures, and tracks of dangerous storms based on the additional data. With the introduction of radio and fast ships, weather information became of vital importance to safe and efficient ship operation. Many countries began regularly scheduled weather forecasts to ships in nearby waters.  Today, weather forecasts as well as charts are prepared from data collected through ship observations. Forecasts of weather and sea conditions arc prepared for ship operation,...

Subsidizing Approved Farm Practices
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Lloyd,   Alan G.
One of the world's leading agricultural economists, T.W. Schultz, recently published an estimate of the effect of the adoption of new techniques on the efficiency of United States' agriculture. Schultz estimated the average increase in efficiency at from 0.8 per cent to 1.35 per cent per annum over the period 1910 to 1950, the rate of increase being even higher in recent years. The statistics available do not permit a similar calculation for Australia. However, the systems of agriculture and the types of technical advances made in Australia and the United States are not dissimilar, and it is known that increases in the productivity of labour in the two countries are roughly equivalent, so that an assumption of an annual one per cent increase in the...

Innovation and Enterprise in Wheat Farming
Provedor de dados: Research in Agricultural & Applied Economics (AgEcon Searh)
Autores: Parish,   Ross M.
This article is concerned with certain aspects of the entrepreneurial behaviour of wheat farmers - in particular, with their adoption of new techniques and means of production. The study is based on data secured in the course of a field investigation carried out late in 1953, in which forty-eight wheat farmers, residing in a particular locality in northern New South Wales, were interviewed.  The primary aim of the investigation was not to estimate the extent to which particular technological innovations are being adopted throughout the wheat belt, or in any particular part of it. Its aim was, rather, to gain some idea of the factors which influence farmers in either adopting or not adopting a particular innovation, or innovations in general. In other...

This paper deals with some Millipedes (Diplopoda), which have been verified associated with or attacking on cultivated plants. The following forms are reported: 1) Orthomorpha (Orthomorpha) coarctata (Saussure, 1860) - Enormous numbers of individuals belonging to this species, whose synanthropic habits are frequentely emphasized, were collected around coffee-plants kept in a nursery. Young plants (with 10 cm) are mentioned as damaged by the species, which gnaws the stem, just above the roots. The dusting with benzene hexachloride (BHC) was successfully employed to prevent the invasions. Other occurrences of O. coarctata are reported, ecological and biological informations being also added. 2) Orthomorpha (Kalorthomorpha) gracilis (C. L. Koch, 1847) -...

Constatação da moléstia do «anel vermelho» do coqueiro no Estado do Rio de Janeiro. Redescrição do agente causador - Aphelenchoides cocophilus (Cobb, 1919) Goodey, 1933 (Nematoda, aphelenchidae)

Autores: Lordello,Luiz Gonzaga E.; Zamith,Adiel Paes Leme.
As it is generally said, the red ring disease of coconut palm (Cocos nucifera L.) is caused by a nematode which is regularly found in the diseased tissues. Such a nematode was described by COBB in 1919 as Aphelenchus cocophilus, having been placed by GOODEY, in 1933, in the genus Aphelenchoides. The species has been found occurring in three States of this country (Alagoas, Sergipe and Bahia). However, the Authors received from the Instituto de Ecologia e Experimentação Agrícolas, in Rio de Janeiro, a few samples of coconut tissues badly infested. So, its area of distribution is considerably enlarged. A. cocophilus is so slender and delicate a form that descriptions based on preserved material are frequentely inadequate. Thus, the Authors took this...

(Temminck) and Scardafella squammata squammata (Lesson). The last one is well known for the beauty of the coloration of its feathers and for the characteristic sounds produced when flying up. Of common occurrence around the local farms, that species can easily be recognized not only for the mentioned peculiarities as for the voice of the adults, which was translated into the Brazilian onomatopoeia by the expression "fogo-apagou". S. squammata's biology being not well known, the Author presents some notes on its nidification,...

This paper deals with some testes of Crotalaria as forage, using rabbits as laboratory animals to detect toxicity, at Piracicaba, São Paulo, Brazil. 1. C. intermedia and C. juncea were palatable, non toxic, the last more productive. Tests on cattle are recommended and selection to improve characteristics as forage too. 2. C. incana and C. verrucosa were little palatable, probably non toxic, poor productive. 3. C. paulina, C. lanceolata (four strains), C. mysorensis, C. gratiana, C. spectabilis, C. breviflora and C. campista were toxic. This results are not according those of others AA. Others species are beeing tested since Crotalaria is a drought resistent legume on this area.

There is in the literature a noteworthy lack of sampling methods to be employed in the selection of papaya fruits for genetical improvement purposes. In the present experiment methods applied to melon and watermelon were extended to papaya with good results. The authors tried to correlate the solids content-as determined by a hand refractometer-with total sugars in the fruit. The correlation does exist being significant and positive. A regression equation was worked out; it permits to calculate the total sugar content provided the Brix value determined by the hand refractometer is known. The equation is as follows: a = 0.57 s where a = total amount of sugar as glucose, and s = total solids.

Agressividade de algumas gramíneas forrageiras na região de Piracicaba
Provedor de dados: Anais da Escola Superior de Agricultura Luiz de Queiroz
Autores: Torres,A. Di Paravicini.
O Autor relata suas observações sôbre o comportamento de doze Gramíneas forrageiras consideradas agressivas na região de Piracicaba, Estado de S. Paulo, Brasil, admitindo que as mesmas podem ser confirmadas em condições tropicais ou subtropicais semelhantes. Estuda a agressividade como uma propriedade inerente à planta, mas dependente de condições edáfico-climático-bióticas para manifestar-se de uma ou outra maneira. Admite que a agressividade, que se verifica em consequência de uma competição pela luz, pelo alimento e pela reprodução, seja uma resultante da intensidade de duas principais condições endogenas: multiplicação e crescimento, debaixo de condições de adatação exógenas favoráveis. Condições favoráveis para certas espécies são desfavoráveis para...

The present paper relates a few experiments carried out to study the distribution of radiozinc in tomato seedlings as well its translocation in adult plants. 1 Tomato seedlings grown in nutrient solution were given during two weeks ca. 0.2 microcuries of Zn65C112; the seedlings were then harvested, and after careful washing of the roots with distiled water and diluted HC1, a radioautograph was taken (Fig. 1); this shows that the whole seedling, including the first cotyledon leaves are active; the Zn65 is preferentially concentrated, however, in the root system; this fact suggests that finding by ROSSITER (1953) that the roots of plants growing under natural conditions had a very high concentration of zinc is not due to soil contamination being ascribable...

During the years 1948, 1949 and 1951 a disease occurred in the cotton crops of the state of S. Paulo Brazil (S. Am.), which caused a severe drop in yields. The abnormality was characterized by a typical reddish - purple color of the leaves, being by this reason, called "vermelhão", that is, reddening of the cotton plant. The disease was associated with a dry season. Among the several hypotheses raised to explain the causes of the disease were: insect attack, potassium deficiency - where from the name "potash hunger" was also given -, and magnesium deficiency: In order to study the problem the Department of Agricultural Chemistry of the College of Agriculture of the University of São Paulo, at Piracicaba, carried out a series of experiments as follows: 1....

Êste trabalho tem por objetivo estudar o efeito que o uso contínuo de sulfato de amônio, superfosfato e cloreto de potássio, determinam no solo. Serviram, como material de estudo, duas experiências de adubação que a Secção de Cereais e Leguminosas do Instituto Agronômico vem executando em Campinas (terra roxa misturada) e Mocóca (terra massapé), durante 16 anos e 12 anos, respectivamente. Foram retiradas amostras compostas de terra, das linhas que receberam adubo e das entrelinhas de três repetições dos seguintes tratamentos : Testemunha, N, P, K, NPK, (2N)PK, N(2P)K e NP(2K). Os resultados analíticos mostraram que o sulfato de amônio aumentou a acidez do solo, enquanto que o superfosfato e cloreto de potássio tiveram pouca ou nenhuma influência nêsse...

Genética de Coffea. XVIII - Variegação no cafeeiro
Provedor de dados: Bragantia
Autores: Carvalho,A.; Antunes Filho,H.
A variegação das fôlhas do cafeeiro tanto em plantas novas como em plantas adultas tem sido freqüentemente observada. Plantas variegadas podem ocorrer espontaneamente nas progénies das diversas variedades de Coffea arabica L., motivo porque não devem constituir variedade distinta dessa espécie, como foi proposto por Cramer. As plantas variegadas em estudo puderam ser agrupadas em duas categorias, isto é, aquelas em que a variegação não se acha associada com anomalias na forma e textura das folhas e aquelas nas quais a variegação é acompanhada dessas anomalias. No primeiro grupo o padrão de variegação não é uniforme para tôdas as fôlhas, enquanto no segundo grupo o padrão é semelhante para tôda a planta. Usualmente apenas alguns ramos das plantas do...

Estudo da solubilidade, em solução de ácido acético a 1%, de alguns materiais calcários de grau de finura comercial
Provedor de dados: Bragantia
Autores: Gallo,J. Romano.
O presente trabalho trata do estudo da solubilidade de alguns calcários de grau de finura comercial. A solubilidade dêsses materiais foi determinada por agitação durante 30 minutos com solução de ácido acético a 1%, tomando-se como referência o carbonato de cálcio puro de laboratório. São feitas considerações em tôrno do método e de seu valor prático, ao lado de outros elementos (composição química e granulometria), na investigação das rochas calcárias moídas existentes no mercado. Os resultados obtidos permitem concluir que a textura influenciou a solubilidade dos calcários dolomíticos. Êstes, por sua vez, mostraram-se menos solúveis que os materiais cálcicos. Os dados apresentados esclarecem que, dentro dos limites de granulometria dos materiais...

Vermelhão do algodoeiro
Provedor de dados: Bragantia
Autores: Costa,A. S.; Sauer,H. F. G.
Uma moléstia do algodoeiro associada à infestação pelo pulgão Aphis gossypii, é descrita. É proposto que o nome vermelhão fique restrito a essa moléstia e que quando esta designação for usada em associação com outras moléstias, seja qualificada em seu emprêgo. São apontadas algumas diferenças que permitem distinguir o vermelhão do afídio de outras condições em que a coloração das fôlhas do algodoeiro é mais ou menos semelhante. Foi verificado que, quando afídios coletados de plantas com vermelhão eram alimentados em algodoeiros novos por 48 horas apenas, os sintomas da moléstia se manifestavam dentro de 12 a 30 dias. Infestações com um afídio por planta foram suficientes para reproduzir a moléstia em alguns casos ; com cinco afídios por planta conseguiu-se...

Melhoramento do cafeeiro: VII - Ocorrência de lojas vazias em frutos de café "mundo novo"

Autores: Antunes Filho,H.; Carvalho,A.
Êste trabalho descreve a estrutura do fruto e o método utilizado na determinação da freqüência de lojas vazias dos frutos do cafeeiro, nas quais não se encontram sementes. Êste método consiste em colher, de cada planta, uma amostra ao acaso de 100 frutos maduros, que são cortados transversalmente, anotando-se em folhas apropriadas o número de sementes dos tipos chato, moca e concha, as que ocorrem em número de três por fruto e o número de lojas vazias, desprovidas de sementes. Esta última anomalia parece resultar da paralização do desenvolvimento do endosperma, o que provavelmente se dá quando esse tecido deveria começar a preencher a cavidade já bem desenvolvida do fruto. Quando isto ocorre, a loja do fruto continúa a se desenvolver normalmente, porém sem...

Neste trabalho são apresentados os resultados preliminares obtidos com a aplicação de diferentes fertilizantes nitrogenados, a fim de se determinar a forma de nitrogênio preferida pelo arroz durante os dois primeiros meses do ciclo vegetativo. Para isso instalou-se uma experiência em vasos contendo terra-roxa misturada e empregando-se os seguintes materiais nitrogenados : salitre do Chile, sulfato de amónio, calciocianamida, uréia, torta de algodão, farinha de chifre e casco, e solução de amoníaco. Os resultados apontaram a uréia como o fertilizante que propiciou maior produção de matéria sêca. Seguiram-se-lhe o sulfato de amônio, solução de amoníaco, farinha de chifre e casco, calciocianamida, torta de algodão e, finalmente, o salitre.

Reação da laranjeira azêda à tristeza
Provedor de dados: Bragantia
Autores: Costa,A. S.; Grant,T. J.; Moreira,Sylvio.
Mudinhas novas de laranjeira azêda podem ser infetadas com o vírus da tristeza por meio do afídio vetor da moléstia ou mais fàcilmente por enxertia. Plantas adultas são muitos resistentes, quase imunes. A recuperação do vírus da tristeza de plantas de laranja azeda infetadas é efetuada com facilidade por meio de enxertia e com muita dificuldade por meio do vetor. Os sintomas comumente apresentados por mudinhas de laranja azêda afetadas, consistem em amarelecimento das fôlhas novas, paralisação no crescimento e eventual queda das fôlhas amareladas. Em caso de infecção com estirpes fracas do vírus, os sintomas são menos evidentes e comumente há recuperação. As fôlhas formadas após recuperação, muitas vêzes apresentam palidez de pequenas extensões das...

Os estudos realizados pelo Instituto Agronômico, visando encontrar o melhor espaçamento para a cultura da mamoneira anã I. A. 38, foram iniciados em 1939 e prolongaram-se até 1945. Nessa ocasião observou-se o efeito de seis tratamentos, tendo-se verificado que para o menor espaçamento estudado - 1,50 x l,50m - as produções foram superiores em todas as localidades onde se realizaram ditos ensaios. No ano agrícola 1948/49 foram iniciados novos estudos, pois que, em um campo de aumento plantado na Estação Experimental de Ribeirão Preto a variedade anã I. A. 38 dera bôa produção no espaçamento 1,00 x 1,00m. Dessa maneira o presente trabalho encerra um novo plano experimental que teve início nesse ano agrícola e se prolongou até 1952/53.

O endosperma de café, tratado segundo a técnica utilizada por Crafts nos seus estudos com Solanum tuberosum L., evidenciou a ocorrência de plasmodesmas nas paredes de suas células. Êstes plasmodesmas apresentam-se como filamentos tênues, na maioria dos casos geniculados e agregados em grupos, localizados nos "campos de pontuações primárias". O aspecto, a morfologia, a freqüência e a distribuição dos plasmodesmas, no endosperma de café, são sensivelmente semelhantes às estruturas vistas e descritas por Quisumbing, em Diospyros kaki L.

Foi realizado um estudo comparativo para verificar a influência da adição de sais de amônio e de farelo de arroz sôbre o rendimento alcoólico obtido pela fermentação do caldo de cana de açúcar da variedade Co. 290. Os dados obtidos nos levaram às seguintes conclusões: 1. O caldo de cana da variedade Co. 290 é pobre em elementos nutritivos para o fermento alcoólico. 2. A adição de 0,1% de sulfato ou fosfato de amônio melhora o processo de fermentação. 3. Os rendimentos alcoólicos mais elevados são obtidos quando o caldo de cana é enriquecido com 0,1% de sulfato ou fosfato de amônio e 0,1% de farelo de arroz. O farelo de arroz parece ter sua atividade ligada ao seu alto teor em vitaminas, principalmente a B1.

Autores: Moreira,S.; Costa,A. S.; Grant,T. J.
Algumas regiões citrícolas, especialmente no continente europeu, ainda não foram, ao que parece, atingidas pela moléstia tristeza dos citros. Os conhecimentos adquiridos durante as investigações feitas sôbre a moléstia permitem indicar como identificá-la e prevenir suas desastrosas conseqüências nos laranjais. Os sintomas gerais nas plantas afetadas são semelhantes aos causados pela podridão do pé (gomose), podendo-se distinguí-la da tristeza examinando as raízes. Há combinações cavalo-enxêrto tolerantes e não tolerantes ao vírus. É, porisso, muito importante o reconhecimento da espécie cavalo, o que se pode fazer no pomar examinando a sua brotação ou observando o grau de congenialidade entre cavalo e enxerto.

Citologia do desenvolvimento dos frutos sem sementes no café "mundo novo"
Provedor de dados: Bragantia
Autores: Mendes,A. J. T.; Medina,Dixier M.; Conagin,Cândida H. T. Mendes.
Uma pequena porcentagem de frutos sem sementes é comum às plantas de tôdas as variedades de Coffea arabica, parecendo tratar-se de um fenômeno puramente fisiológico. No café Mundo Novo porém, além dêste tipo de plantas, há outras com elevada porcentagem de lojas vazias ("chochos"). Constituindo isto um grave defeito para uma variedade comercial, procurou-se estudar a sua causa. As observações feitas no processo da microsporogênese mostraram irregularidades na distribuição dos cromossômios. Sendo encontradas tanto nas plantas de alta porcentagem como nas de baixa porcentagem de chochos, não deve residir nessas anomalias a causa procurada. Em estudos comparativos dos dois tipos de plantas do Mundo Novo e da variedade bourbon, pôde-se verificar : a) que, em...

Autores: Krug,C. A.; Carvalho,A.; Antunes Filho,H.
A variedade laurina, comparada à var. typica de Coffea arabica, se caracteriza por seu menor porte, forma cônica, ramificação mais densa, internódios mais curtos, fôlhas elíticas e menores, flôres de tamanho normal, frutos e sementes menores e afilados na base. Numerosas autofecundações e cruzamentos foram realizados e os resultados obtidos permitiram concluir que os característicos diferenciais da var. laurina são controlados por um par de fatôres genéticos recessivos, sendo as plantas laurina de constituição lrlr.

Ação da água oxigenada sôbre a matéria orgânica do solo
Provedor de dados: Bragantia
Autores: Verdade,F. da Costa.
Diversos tipos de análise de solo exigem a destruição prévia da matéria orgânica, sendo a água oxigenada o oxidante mais usualmente empregado. Nêste trabalho a ação da água oxigenada sôbre o carbono e o nitrogênio do solo foi estudada com pormenores, para esclarecer alguns pontos relativos à oxidação. A água oxigenada não destroi totalmente a matéria orgânica, qualquer que seja a concentração empregada. Em virtude da solubilidade de alguns produtos de oxidação do carbono e da remoção de resíduos vegetais não decompostos, a lavagem do solo com água destilada, após os tratamentos com aquele oxidante, produz maiores perdas de carbono que nos tratamentos sem lavagem. O nitrogênio só é eliminado em porcentagens altas quando o solo é lavado ; caso contrário, a...

Provedor de dados: Bragantia
Autores: Teixeira,C. G.; Salati,A.
A variedade de cana de açúcar mais disseminada no Estado de S. Paulo é a Co.290. Não é a melhor variedade para produção de álcool etílico em virtude de seu caldo fermentar com certa dificuldade. A adição de 0,1% de sulfato de amónio e farelo de arroz corrige êste defeito. Várias estirpes de Saccharomyces cerevisiae Hansen foram submetidas a testes para verificar quais delas eram as mais eficientes na fermentação do caldo de cana. A análise estatística dos rendimentos alcoólicos obtidos evidenciou serem mais eficientes as estirpes F-29, F-34, F-1 e F-2.
