Observações sôbre alguns diplópodos de interêsse agrícola

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) - Observed frequentely associated with the former species, being however less numerous. Both forms are very active, seemming to be widely distributed throughout the State of S. Paulo. 3) Cylindroiulus (Aneuloboiulus) britannicus (Verhoeff, 1891) - This species represents the first european Millipede verified in Brazil, by O. SCHUBART (1942a). The Author obtained a few specimens associated with O. gracilis, from the roots of lettuce plants. The lesions shown by the stem just above the roots seem to be due to both species. 4) Alloporus setiger Broelemann, 1902; Gymnostreptus olivaceus Schubart, 1944 and Pseudonannolene tricolor Broelemann, 1902 - Total damages determined by these species (mainly G. olivaceus) were observed in cultures of sugar-beet and melon. Actually, the Millipedes destroyed entirely the roots of the former plant and the fruits of the latter, representing a serious pest, here reported by the first time. Ecological and bionomical data are also included. 5) Pseudonannolene sp. (possibly P. paulista Broelemann, 1902) - Verified gnawing sweet-potatoes, about the crackings exhibited by the tubers. The crackings in sweet-potatoes appear to result in certain instances from a root-knot nematodes infection (Meloidogyne sp). P. paulista was recentely observed attacking potatoes, destroying from 6 to 30% of the tubers, according to the variety (BOOCK & LORDELLO, 1952).

Nova contribuição para o conhecimento das saúvas do Estado de São Paulo

Êste trabalho tem como objetivo principal descrever aspectos ecológicos e bionômicos das saúvas de 104 municípios do oeste do Estado de São Paulo. Em tôda a região pesquisada somente três espécies de saúvas foram constatadas: l.ª) Atta sexdens rubropilosa Forel, 1908 (saúva limão); 2.ª) A. laevigata (F. Smith, 1858) (saúva-de-vidro ou saúva cabeça-de-vidro); 3.ª) A. capiguara Gonçalves, 1944 (saúva parda). Uma das grandes surpresas, durante o desenvolvimento dêste trabalho, foi o de se comprovar que a saúva parda A. capiguara é a espécie mais frequente e a mais importante. A sua importância e a das duas outras espécies é, entretanto, salientada no capítulo 5 (BIONOMIA).
