| Helicoverpa armigera (Hübner) destaca-se entre os principais lepidópteros desfolhadores de culturas brasileiras nas duas últimas safras. Visando aprimorar as técnicas de criação de H. armigera em laboratório, foi avaliada uma metodologia de criação no Laboratório de Resistência de Plantas a Insetos e Plantas Inseticidas (LARESPI) da FCA/UNESP, Botucatu. Para criação, os adultos identificados quanto ao sexo e separados em casais são mantidos em gaiolas (tubos de PVC, 20 cm de diâmetro e 30 cm de altura). A face superior das gaiolas são vedadas com tecido voil, permitindo aeração e alimentação dos adultos. A face inferior é apoiada em prato de plástico (28 cm de diâmetro) recoberto com papel filtro. Internamente as gaiolas são forradas com papel kraft... |

| Abstract: Antifeedant and repellent effects of two different extracts from native Solanum species Solanum bistellatum and Solanum sisymbrifolium on Cryptotermes brevis were evaluated. The extracts obtained, particularly the dichloromethane extracts and the enriched fraction of sugar esters from S. sisymbrifolium and S. bistellaltum, showed antifeedant and repellent action against the termite. The antifeedant effect of dichloromethane extract from S. sisymbrifolium at the concentration of 25.00mg/mL reached 100%, while the repellent action of the dichloromethane extracts and that of the enriched fraction of sugar esters at the concentration of 1.00mg/mL was higher than 90%. In case of S. bistellatum, the antifeedant effect of the dichloromethane extract and... |

| Abstract: The corn earworm Helicoverpa zea (Boddie) and the old world bollworm Helicoverpa armigera (Hubner) (Lepidoptera: Noctuidae) are allopatric species and occur in important agricultural crops. In maize, both species tend to infest the ear. The introduction of H. armigera in Brazil has created a new scenario, where these Helicoverpa species might cohabit and interact with one another, affecting the prevalence of each species in the agroecosystem, integrated pest management, and insect resistance management. In this study, larval occurrence and proportion of these species in maize was assessed in three regions of Brazil during three crop seasons. Interaction between the species was evaluated in interspecific and intraspecific scenarios under... |

| Resumo: Neste estudo foram realizadas a caracterização molecular e a comparação da biologia de estádios imaturos de Helicoverpa armigera Hübner (Lepidoptera: Noctuidae). Foram estabelecidas três colônias desta espécie, a partir da coleta de insetos oriundos dos estados de São Paulo, Bahia, e Distrito Federal, em plantas de citros, algodão e milho, respectivamente. Análises genética foram conduzidas usando microssatélites de forma a verificar a similaridade genética dos insetos de cada colônia. A biologia de imaturos foi estudada sob condições de laboratório (T = 25 ± 1 °C, UR = 70 ± 10%, fotoperíodo = 14:10 h L:D). A análise de microssatélites revelou variabilidade genética nos espécimes amostrados e que o agrupamento dos indivíduos foi independente da... |

| The life-history and biology of Dirphia araucariae Jones, 1908, including its life fertility table, are here described. Moths were reared in the laboratory under controlled conditions on their host plant, Araucaria angustifolia (Bertoloni) O. Kuntze ? Araucariaceae. We describe several life-history traits of the species, namely: developmental period, survival rate, growth rate, fertility, fecundity, sex ratio, cephalic capsule width, and pupal weight. Mean duration of life stages were: egg = 26.78 days; larva = 61.78 days; repupa = 6.85 days; pupa = 62.46 days; adult = 8.37 days. We found statistically significant differences between sexes for adult, larval and pupal stage duration; larval stage was longer in females while pupal stage was longer in males.... |

| ABSTRACT: The biotic potential and reproductive parameters of Spodoptera dolichos (Fabricius, 1794) were evaluated under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The longevity, pre-, post- and oviposition periods, fecundity, and fertility of 25 couples were evaluated. The longevity of females (12.9 days) was not significantly different than that of males (12.4 days). The mean durations of the pre-, post- and oviposition periods were 3.0, 0.4 and 10.4 days, respectively. The mean fecundity was 4,086.0 eggs per female and mean fertility was 3,557.8 larvae per female. On average, a female copulated 1.4 times. The biotic potential of S. dolichos was estimated at 7.138 x 1018 individuals/female/year. The net reproductive rate (Ro)... |

| Biotic potential and reprodutcive parameters of Spodoptera eridania (Stoll) (Lepidoptera, Noctuidae) in the laboratory: This study aimed to evaluate the biotic potential and reproductive parameters of Spodoptera eridania (Stoll, 1782) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photophase). The longevity, pre-, post- and oviposition periods, fecundity and fertility of 15 couples was evaluated. The longevity of females (10.80 days) was not significantly higher than those of males (9.27 days). The mean durations of the pre, post and oviposition periods were 2.067, 0.600 and 8.133 days, respectively. The mean fecundity per female was 1,398 eggs and the mean fertility was 1,367.50 larvae. On average, females copulated 1.133 times. A strong... |

| ABSTRACT: This study aimed to evaluate the biotic potential, life table parameters and fertility of Spodoptera albula (Walker, 1857) under controlled conditions (25 ± 1°C, 70 ± 10% RH and 14 hour photo phase). The longevity, pre, post and oviposition periods, fecundity and fertility of 13 couples were evaluated. The longevity of females (13.500 days) was significantly higher than those of males (11.154 days). The mean durations of the pre, post and oviposition periods were 2.615, 1.769 and 9.385 days, respectively. The mean fecundity was 1.417.69 eggs and mean fertility was 1.340.401 larvae, per female. On average, females copulated 1, 231 times. A strong positive correlation was observed between the number of copulations and fecundity (r = 0.847, p... |
