| Abstract: The objective of this work was to identify the sex pheromone of Spodoptera cosmioides and to evaluate whether there is pheromone cross-attraction in Spodoptera sp. (Lepidoptera: Noctuidae). Spodoptera cosmioides gland extracts were analyzed by GC-FID and GC-MS. Wind tunnel and electrophysiology experiments were conducted to evaluate the role of gland compounds. In the field, different pheromone traps were tested: S. frugiperda commercial lure; (9Z)-9-tetradecenyl acetate (Z9-14:OAc) and (9Z,12E)-9,12-tetradecadienyl acetate (Z9,E12-14:OAc) trap; two females of S. cosmioides trap; and hexane control trap. Four acetates were identified in the S. cosmioides female gland extracts as Z9-14:OAc, Z9,E12-14:OAc, (11Z)-11-hexadecenyl acetate (Z11-16:OAc)... |

| A quantidade e qualidade das folhas de amoreira (Morus alba L.) exercem influência marcante sobre o desenvolvimento do bicho-da-seda e são, por sua vez, influenciadas por fatores como a idade das folhas, época do ano e características genéticas dos cultivares. Avaliou-se a produção e a qualidade nutricional de folhas de cinco cultivares de amoreira em diferentes épocas do ano e de colheita, objetivando verificar sua adaptação na região de Jaboticabal (SP). As folhas dos cultivares 'Miura', 'Korin', 'Calabresa', 'FM86' e 'FM Shima-Miura' foram colhidas na primavera, verão e outono após 45, 60, 75 e 90 dias da poda (DAP) e avaliadas quanto à produção de folhas níveis de proteína bruta (PB) e fibra em detergente neutro (FDN). As melhores produções foram... |

| Juvenile hormone analogues have been tested as insect growth regulators in silkworm (Bombyx mori), seeking an increment of silk production. These chemical products, when applied in small or moderate rates, promote the extension of the last larval instar. To understand the physiologic consequences on silk production by the silkworm strain C115 x N108, the application of methoprene, a juvenile hormone analogue, was performed to evaluate its effects on larval development and silk production. Methoprene was topically applied 48h after the fourth larval ecdysis, on the dorsal integument of the 2nd thoracic segment of the insects, at seven rates between 0 and 20 ng a.i. Methoprene influenced positively the duration of the fifth instar and the weight gain of the... |
