dc.descriptionEfetuou-se, em laboratório, um estudo sobre a fecundidade, fertilidade e duração de vida de casais de Panstrongylus megistus e da fecundidade e duração de vida de fêmeas virgens dessa espécie, submetidos a jejum, após a última ecdise. Das fêmeas acasaladas, 22,2% puseram ovos, dos quais 4,4% estavam férteis. As fêmeas tiveram maior resistência ao jejum que os machos. Das fêmeas virgens em jejum, apenas 10% puseram ovos, com baixa de ovipostura por fêmeas (0,47). A resistência ao jejum foi mais baixa nas fêmeas virgens do que naquelas que permaneceram sempre com os machos.
dc.descriptionA laboratory study was conducted on the fecundity, fertility and life span of Panstrongylus megistus pairs and on the fecundity and life span of P. megistus virgin females submitted to starvation after the last moulting. Of the mated females, 22.2% laid eggs, 4.4% of which were fertile. Females resisted starvation more than males. Of the starved virgin females, only 10% laid eggs, with a low egg-laying rate (0.47) per female. Resistance to starvation was lower in virgin than in mated females.
