O CNPGC realizou um experimento em quatro anos consecutivos (1991-1995). A cada ano, um rebanho de 120 vacas nelores, com bezerro ao pe, foi dividido em dois grupos, levando-se em consideracao as idades e os pesos das vacas e as idades dos bezerros. Durante a estacao de monta (novembro a fevereiro), foram mantidos tres touros, testados andrologicamente, em cada grupo. Em um dos grupos aplicaram-se inseticidas com intervalos que variavam com o principio ativo utilizado, em cada vaca e touro. Os dois grupos foram mantidos em piquetes separados, formados de Brachiaria decumbens, rotacionados a cada catorze dias, com uma taxa de lotacao de 1 UA/ha. As contagens da mosca nas vacas foram realizadas, tambem, a cada catorze dias. As vacas foram pesadas a cada dois...

The worms Polydora. damage the oysters, Crassostrea gigas, by foraging the shell, training the formation of galleries and chambers with mud. The IFREMER'S REMORA network which has in charge to survey the oysters Crassostrea gigas in France, has showed an increase of the infestation of oysters since 1993 (first year of the network). The study had for goal first to estimate the spatial and temporal variations of the infestation of the oysters in 1999, by using two methods: the infestation index, the number of worms by individual and a quality index, the Polydora Index (IP varies from 0 to 1) which is based on 5 classes of the oysters quality (from 0 to 4) in relation to the aspect of the valves

Observations sur le cycle de Marteilia refringens

New nemertean worms (Carcinonemertidae) on bythograeid crabs (Decapoda : Brachyura) from pacific hydrothermal vent sites

Grizel, Henri; Tige, Gilbert.

Observations on the cycle of Marteilia refringens in light and electronic microscopy led us to realise in situ experiences of experimental infestation. According to the rivers the period of infestation varied between may and auguste. During the winter the parasite seems to be absent from the tissues of the oyster.

Résumé de nos observations sur l'infestation des moules du Pertuis Breton par Mytilicola intestinalis Steuer

Shields, J; Segonzac, Michel.

Several species of crabs from hydrothermal vent sites in the Pacific Ocean Were found to be infested by small, symbiotic nemertean worms. Worms occurred on both male and female crabs, and were located in mucous sheaths adhering to the axillae between the limbs of males and females, the setae of the pleopods of females, and the sterna of infested male and female crabs. Only juvenile and regressed adult worms were observed, primarily because no ovigerous hosts were examined. Similar species of worms mature by eating eggs, then regress or die after host eclosion. Based on the size of the worms from file vent crabs, their habitus with their crustacean hosts, the presence of accessory stylet pouches, and the presence of a single stylet on a large basis...

Mytilicolas orientalis Mori : son action sur les huîtres du bassin d'Arcachon au cours de l'été et de l'automne 1977

Brienne, Henri.

Mytilicola intestinalis Steuer habite les moules du Pertuis Breton. Les premiers exemplaires ont été décelés en janvier 1960, dans un lot de moules provenant de bouchots construits sur les vases de Marsilly. Il semble que l'introduction de ce copépode soit récente, bien que la mortalité constatée aux environs de 1930 puisse être protée au compte de mytilicola. Nous avons pensé qu'il serait intéressant de publier les résultats des recherches effectuées depuis l'apparition du parasite et de faire connaître les dispositions qui ont été prises pour limiter sa propagation et assurer la production à venir des moules. Cette étude a porté sur les moules de culture-bouchots de la baie de l'Aiguillon et sur les moules des gisements naturels.

Le copépode Mytilicola orientalis Mori parasite de l'huître Crassostrea gigas du bassin d'Arcachon depuis le printemps 1977. Taux et intensité de l'infestation ont fortement augmenté à partir du mois de juillet. La parasitose s'est alors traduite par une diminution sensible de l'état d'engraissement des huîtres les plus atteintes ; les sujets maigres abritaient en moyenne quatre fois plus de copépodes que les sujets en bon état physiologique. Le parasite semble responsable des mortalités plus ou moins accentuées qui ont sévi sur l'ensemble du bassin en été et en automne 1977. Lors d'infestations massives et prolongées, une étude histologique nous a permis de constater une dégradation importante de la paroi du tube digestif des huîtres.

Mytilicola orientalis Mori, Crassostrea gigas Thunberg's parasite, in the basin of Marennes Oleron : impact on the condition and the biochemical composition of oysters during rearing

Marteil, Louis; Trochon, Pierre; Le Dantec, Jean; Moreau, Jean.

La présence d'Hexamita chez l'huître a été signalée par Certes dès 1892 mais son rôle dans l'étiologie de certaines maladies n'a été précisé qu'en 1952 par Mackin, Korringa et Hopkins. En Hollande, au Canada, aux U. S. A. ce protozoaire a été jugé responsable de mortalités importantes, survenant particulièrement dans les bassins de stockage, pendant l'hiver: une forte densité de peuplement, un renouvellement insuffisant de l'eau, une basse température étaient considérés comme des facteurs favorables au développement de ce flagellé.

Crassostrea gigas Thunberg's infestation by Mytilicola orientalis. Mori in 1979 in the basin of" Marennes-Oléron presents two maxima, one during spring, the other during autumn. The parasites have infested until 64 %of bred oysters.. The intensity of infestation la weak (93.5 %of oysters are infested by lass than six females) and depend on the hosts'size. By this fact, slgnificant impact appears only in spring and in winter. A middle infestation of more than three M. orientalis females seems to induce a significant decrease of rates of carbohydrates and of glycogen

First record of Megaselia scalaris (Loew) (Diptera: Phoridae) infesting laboratory colonies of Triatoma brasiliensis Neiva (Hemiptera: Reduviidae)

Neotropical Entomology

Costa,Jane; Almeida,Carlos E.; Esperança,Gleidson M.; Morales,Nínive; Mallet,Jacenir R. dos S.; Gonçalves,Teresa C.M.; Prado,Angelo P. do.

Megaselia scalaris (Loew) is a cosmopolitan and synanthropic scuttle fly, eclectic in its feeding habits and acts as detritivore, parasite, facultative parasite, and parasitoid. Here we report for the first time M. scalaris infesting laboratory colonies of Triatoma brasiliensis Neiva, the most important Chagas disease vector in semiarid areas of Brazil. M. scalaris larvae were found feeding inside bugs; pupae were found in the esophagus and intestinal regions of T. brasiliensis through dissection. Other relevant information about this finding is also described in this note, including some preventive measures to avoid laboratory colonies infestations.

Host plants of the carambola fruit fly, Bactrocera carambolae Drew & Hancock (Diptera: Tephritidae), in Suriname, South America

Neotropical Entomology

Sauers-Muller,Alies van.

Fruits were collected over a 12-year period to determine the host status for the Carambola fruit fly, Bactrocera carambolae Drew & Hancock, and other tephritid species in Suriname, South America. Over 11,000 fruit samples were collected from many locations and the total of 20 fruit species were recorded as host, ranging in infestation from heavy to occasional. Over 650 samples of 188 fruit species, including many wild species, were collected and no fruit flies were reared. This work, which started specifically to obtain information on the Carambola fruit fly, resulted also in detailed information regarding the importance, distribution and host preferences of several Anastrepha species, and the status of fruit fly parasitoids.

The paper presents data collected in an assessment of effects of water hyacinth infestation on phytoplankton productivity in Lake Naivasha, Kenya. A summary of the status of control and strategies for the future is given. The ecological effects of water hyacinth, Eichhornia Crassipes, on Lake Naivasha have received little attention compared to the large body of work available on the weed’s socioeconomic impact on the country’s water ways and methods for its removal. This study was conducted to determine if water hyacinth infestation in Lake Naivasha affects phytoplankton productivity. Several sampling stations were set up in the lake at sites where the floating mats of the weed were present and sites where the weed was absent. Phytoplankton chlorophyll-a...

Toxicity of pymetrozine and thiamethoxam to Aphelinus gossypii and Delphastus pusillus

PAB

Torres,Jorge Braz; Silva-Torres,Christian Sherley Araujo; Oliveira,José Vargas de.

The objective of this work was to study the toxicity of pymetrozine and thiamethoxam to the cotton aphid parasitoid Aphelinus gossypii Timberlake and to the whitefly predator Delphastus pusillus (LeConte). Cotton leaves containing mummies of the parasitoid A. gossypii were collected and treated with seven concentrations of both insecticides. Parasitoid emergence was not affected by pymetrozine and ranged from 59.9% to 75.0%, but decreased with the increase of thiamethoxam concentrations ranging from 30.2% to 69.6%. Cotton leaves infested by whitefly and treated with recommended rates of both insecticides were collected three hours, three days and six days after spraying and colonized with larvae and adults of D. pusillus. Predators released on...

In the Western Region of Brazil, it is usual to have two agricultural harvests in the same cropping season. Usually the first crop is soybean, followed by corn. In areas where corn is not planted due to a delayed harvest of soybean, farmers generally do not use winter crops. For these areas, the planting of winter oilseed crops aiming at the production of bio-fuels is one of the best alternatives; in addition, this would help in reducing the occurrence of weed species at the following summer crop. This study aimed to assessing the weed community in distinct winter crops post soybean crop, in terms of species composition, level of infestation and severity of occurrence. The following treatments were evaluated: agriculture under a no-till system with winter...

Rhynchosia capitata is a newly emerging threatening weed of summer crops in many Asian countries. We conducted 2-yr experiments to evaluate R. capitata competition with mungbean under irrigated conditions. Rhynchosia capitata was allowed to compete with mungbean for 0, 3, 4, 5, 6, 7 weeks after planting and for full crop season. The competitive ability of R. capitata was assessed by measuring its dry weight, micro and macro nutrient contents and uptake; and its effects on mungbean growth and yield parameters. The results showed that full season weed competition produced highest dry weight of R. capitata and its macro and micronutrient contents and uptake. Yield and yield components of mungbean decreased in a linear fashion with increase in competition...
