Resumo: The 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 female (87.7 eggs) occurred with 49 days and the smallest (32.2 eggs) with 63 days of female age. The remating occurred after the exhaustion of spermatic reservations, starting on 28th day. The fecundity of C. externa females increased with elevation of the relative humidity of air. It was also verified a fast embryonic development with increase of temperature and female age. All these results supply subsidies for knowledge of the reproduction of C. externa in cotton system

Portanto, estudou-se o efeito da idade das fêmeas e de fatores ambientais sobre a reprodução de Chrysoperla externa (Hagen, 1861) (Neuroptera: Chrysopidae). Adultos do predador foram criados em gaiolas de PVC, fechadas na parte superior com tecido de malha fina (organza), colocadas sobre plantas de algodão em casa-de-vegetação. A maior produção de ovos por fêmea (87,7 ovos) ocorreu aos 49 dias, e a menor (32,2 ovos), aos 63 dias de idade. O reacasalamento ocorreu após o esgotamento das reservas espermáticas, a partir do 28o dia. A fecundidade de fêmeas de C. externa aumentou com a elevação da umidade relativa do ar. Verificou-se, também, um rápido desenvolvimento embrionário com a elevação da temperatura e com fêmeas longevas.
