Resumos
Introduzimos a técnica da copulação induzida para a manutenção e criação em cativeiro, do Anopheles albitarsis e do A. aquasalis, objetivando facilitar futuros trabalhoscom estas espécies de difícil cruzamento espontâneo em laboratório.
Many species of mosquitoes are unsuited to life in a laboratory because they fail to copulate in cages. This situation may be largely eliminated by the technique in current use for manually inducing inseminations as outlined. We have used this technique for the first time in relation to Anopheles albitarsis and A. aquasalis, species of malaria vectors which are difficult to mate spontaneously in captivity. The pre-mating age of the males and the temperature at which they are held affect the ability of male to transfer sperm. Mating males 8 to 14 days old with females at any age, resulted in a high order of insemination. Temperature of 25°C and humidity of 80% RH enhanced the degree of insemination.
