Macedo, Luciano Pacelli Medeiros; Amorim Pessoa, Luis Gustavo; Souza, Brígida; Loureiro, Elisângela de SouzaIt was aimed to study biological and behavior aspects of larvae and adults of Chrysoperla externa in greenhouse, on cotton plants. Recently hatched larvae were released on the upper third of cotton plants, which were previously infested with Aphis gossypii,. After emergence, adults were separated by sex and packed in cylindrical PVC recipients with cotton plant. We evaluated the duration of each larval, pre-pup...

Macedo, Luciano Pacelli Medeiros; Souza, Brigida; Carvalho, Cesar Freire; Ecole, Carvalho Carlos; Goussain, Marcio MarcosThe biotic and abiotic factors affect the reproductive potential of insects. Thus, the effects of female age and environmental factors on reproduction of Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae) were studied. Adults of the predator were reared in "PVC" cages, closed in the upper portion with a thin mesh, organdie, placed on cotton plants at a greenhouse. The largest production of eggs by fema...
