| A short contribution to the Natural History of some Brazilian Frigillidae The following species of Brazilian Fringillidae are mentioned here, the first of which being more deeply studied: 1 - Oryzoborus angolensis angolensis (Linnaeus). 2 - Oryzoborus crassirostris maximiliani Cabanis. 3 - Cyanocompsa cyanea sterea Oberholser. 4 - Coryphospingus cucullatus rubescens (Swainson). About each one of the referred species, the Author gives native names, some datas and observations on its reproduction and behaviour under captivity, as well as on its natural alimentation. Some considerations about the geographical races of Oryzoborus angolensis: O. a. angolensis (Linnaeus) and 0. a. torridus (Scopoli) -are also made. Both the races occur in Brasil and, according... |

| This paper includes a few notes on some Homoptera insects of the genus Fulgora, according to a study carried out on a little collection belonging to the Laboratory of Zoology of the Escola Superior de Agricultura "Luiz de Queiroz" (Piracicaba, Brazil). The following species are mentioned: F. servillei Spinola, F. lucifera Germar, F. orthocephala (Pinto da Fonseca) and F. cearensis (Pinto da Fonseca). The types of the latter having been collected in Fortaleza (Ceará), its area of distribution is considerably enlarged by the information of its occurrence in the State of São Paulo. |

| Tomato roots heavily disfigured by root-knot nematodes were throughly mixed with soil. At various time intervals, samples were taken from the mixture and treated in closed containers by each of the folio wing nematicides: D.D., E.D.B. and M.B. The efficacy of the treatment was tested by setting indicator plants in the treated soil and by examining their roots for the presence of galls two months later. In other words, the ability of the three nematicides to penetrate nematode galls after various periods of rotting, which varied from 5 to 30 days was studied. The main conclusions drawn are as follows: a) no nematicide among the three listed above showed the ability for complete destruction of the nematodes protected inside the roots, for a number of small... |

| Com o objetivo de se obter informações sobre o desenvolvimento de Meloidogyne exigua Goeldi, 1887, em raízes de cafeeiro (Coffea arabica L.) cv. Mundo Novo, em três ambientes, plântulas no estágio do primeiro par de folhas verdadeiras foram transplantadas para copos plásticos com 25O ml de solo. Trinta dias depois, cada muda foi infestada com 600 larvas pré-parasitas e transferidas para as diversas condições de estudo: casa de vegetação, sala de temperatura constante e próximo de plantas adultas num cafezal. As raízes foram coletadas cada dois dias, coloridas e dissecadas, sendo os exemplares de M. exigua classificados de acordo com o estádio de desenvolvimento. Os resultados permitiram concluir que o desenvolvimento de M. exigua foi influenciado pela... |

| 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) -... |

| 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... |

| Seven species of the nematode genus Mononchus Bastian, 1865, were found in the State of São Paulo, Brazil. Such are: M. subsimilis Cobb, 1917; M. ibitiensis Carvalho, 1951; M. piracicabae Lordello, 1953; M. risoceiae Carvalho, 1955; M. soutoi Carvalho, 1956; M. coronatus Carvalho, 1956; and M. jairi n. sp. Outside the State, the following species have been found: M. papillatus (Bastian, 1865) Cobb, 1916; M. monhystera Cobb, 1917; M. muscorum (Dujardin, 1845) Cobb, 1916; M. gymnolaimus (Cobb, 1893) Cobb, 1916; M. consimilis Cobb, 1917; M. trichurus Cobb, 1917; M. reversus Cobb, 1917; and M. dentatus Cobb, 1917 (LORDELLO, 1953). This field of investigation has scarcely been touched and additional collections will doubtless add new forms to the number of... |

| Biology of Arsenura xanthopus (Walker, 1855) (Lep., Adelocephalidae), a pest of Luehea spp. (Tiliaceae), and notes on its natural enemies. In the beginning of 1950, one of the Authors made some observations about the biology of Arsenura xanthopus (Walker), in Piracicaba, State of S. Paulo, Brazil. From 1951 to 1953, both Authors continued the observations on such an important Adelocephalidae, the caterpillars of which represent a serious pest of Luehea spp. leaves. Actually, in some occasions, the caterpillars can destroy completely the leaves of the trees. The species is efficientely controlled by two natural enemies: an egg parasite (Tetrastichus sp., Hym., Eulophidae) and a fly attacking the last instar caterpillar (Winthemia tricolor (van der Wulp),... |

| This paper is a small contribution to the knowledge of Megalopyge lanata (Stoll, 1780). The caterpillars of this moth are called " Sassurana" and are very known by the fact of having the body densely covered with long hairs, among which are some setae connected with poison glands. They damage the leaves of a large number of plants, enclosed in at least 14 botanical families, being therefore poly-phagous. M. lanata has a great taxonomical importance for it being the type of the family Megalopygidae Berg, 1882. The Author presents some notes on the various common names used for it, on its known natural enemies and also about the biology, according to the observations made by him in the Laboratory of Zoology, of the Escola Superior de Agricultura "Luiz de... |

| Irish potato tubers imported from Holland and Germany were planted at the Instituto Agronômico Experiment Station, Campinas, in April, 1955. At digging time, in July, 1955, the tubers were found to be injured by nematodes belonging to the genus Ditylenchus. No visible symptoms were found on the plants during the growing season, since the nematodes did not attack the stems. However, prevailing weather conditions from April to July were not favorable for nema activities, with low temperature and rain precipitation. Therefore, it does not seem safe to assume that, as a rule, the nemas do not attack buds and stems, for further observations may reveal such an occurrence, as it has been reported in the literature. The injury was characterized by spots consisting... |

| The main wild doves of the region of Piracicaba (State of S. Paulo, Brazil) are Columba cayennensis sylvestris Vieillot, Oreopeleia montana montana (L.), Leptotila verreauxi decipiens Salvadori, Columbigallina talpacoti talpacoti. (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,... |

| Vinte cultivares de banana (Musa spp.) foram avaliados em condições naturais de infestação em relação aos nematóides formadores de galhas Meloidogyne incognita e M. javanica, espécies estas mais difundidas no País. Verificou-se que todos os cultivares foram susceptíveis a M. incognita e oito a M. javanica. Suspeitou-se, no entanto, que caso houvesse infestação uniforme do nematóide javanês, todos os cultivares seriam eventualmente parasitados. Descrevem-se também os sintomas apresentados pelos sistemas radiculares dos cultivares. Do ponto de vista econômico, resta recomendar remoção das raízes das mudas e do solo a elas aderido, e plantio em solos preferencialmente livres de Meloidogyne spp. |
