dc.description | Estudou-se, em laboratório, a influência do acasalamento na fecundidade e fertilidade de fêmeas de P. megistus, alimentadas a cada 14 dias. Foram formados dois grupos: I - fêmeas que copularam uma única vez; II - fêmeas que permaneceram sempre com os machos. Das fêmeas do grupo I, apenas 56,7% puseram ovos férteis, enquanto que 90% das fêmeas do grupo II tiveram ovos férteis. A duração da ovipostura fértil foi também maior nas fêmeas do grupo II. Destas últimas, algumas foram capazes de copular até sete vezes ao longo de sua vida, o que inviabiliza o uso de machos estéreis no controle desses insetos. Os autores discutem também a influência na fecundidade e fertilidade das fêmeas dos dois grupos e na longevidade dos insetos, de componentes no sangue dos pombos que serviram de repasto aos triatomíneos. | |
dc.description | A study of the effect of mating in the fecundity and fertility of females of P. megistus fed on pigeon blood every 14 days, was carried out in the laboratory. Two groups were constituted: I - females which mated only once; II - females which stayed always with the males. Only 56.7% of group I females laid fertile eggs, while as much as 90% of group II females laid fertile eggs. The duration of the fertile oviposition was greater in the females which stayed always with the males. Some females of this group were able to mate up to seven times throughout their life-span. This fact render useless sterile males in the control of these insects. It is suggested that the components of pigeon's blood used for feeding the triatomines could have an influence upon the fecundity and fertility of the female sof the two groups. | |
