Biologia de Hylesia nigricans (Berg) (Lepidoptera, Saturniidae, Hemileucinae)

Abstract: Biologia de Hylesia nigricans (Berg) (Lepidoptera, Saturniidae, Hemileucinae). As espécies de Hylesia Hübner, [1820] destacam-se entre os demais lepidópteros por apresentarem ação urticante tanto durante a fase larval (erucismo) quanto na fase adulta (lepidopterismo). Hylesia nigricans (Berg, 1875) cuja ocorrência é registrada do sudeste do Brasil até Argentina e Uruguai vem sendo relacionada como praga de diversas frutíferas cultivadas e essências florestais, também têm sido relacionada com diversos episódios… Show more

“…In addition, after the behavioural reaction is triggered, the larvae regurgitate a greenish substance and disperse throughout the cage, impairing their ability to return to their original state of aggregation. This aggressive behaviour, followed by dispersion, could be responsible for the low larval viability (Table 2) in comparison with previous reports for A. illustris (91.6 %; Specht et al, 2006a), A. naranja (97.3%) (Specht et al, 2007) and Molippa cruenta (Walker, 1855) (91,6%) (Specht et al, 2010). We strived to interfere as little as possible with the larvae during the maintenance activities, at least until the prepupal period.…”

“…As observed for most Hemileucinae (e.g. Lemaire, 2002;Specht et al, 2006aSpecht et al, , 2006bSpecht et al, , 2007aSpecht et al, , 2007bSpecht et al, , 2009Specht et al, , 2010, larvae of P. circumstans, particularly in the first instar, have a gregarious habit. For this reason, it was not possible to rear each larva individually to estimate the duration of the instars separately.…”

“…Resultados recentes com criação de A. llustris (SPECHT et al 2006b) e Hylesia nigricans (Berg, 1875) (SPECHT et al 2006a), indicam a ocorrência de valores da taxa média de crescimento muito próximos, em torno de 1,4 a cada ínstar.…”

“…II) que é muito curta e, presumivelmente encontra-se relacionada com o fato dos hemileucíneos não se alimentarem durante a fase adulta (LEMAIRE 2002). Esta espécie, apresentou período de oviposição mais prolongado que a pré-oviposição, conforme observado para H. nigricans (SPECHT et al 2006a) e A. illustris (SPECHT et al 2006b). …”
