在恒温恒湿条件下,观察并研究了安汶巨蚊(Toxorhynchites amboinensis)的某些生物学特性。该蚊发育历期:卵2天幼虫11—12天、蛹期5天。该蚊幼虫每天捕食35条白纹伊蚊(Ae.albopictus)幼虫;随食量减少该蚊幼虫期延长,最长可达80天:成蚊羽化后第八天产卵,平均每天产11粒;雌蚊寿命40天,雄蛇95天;雌雄性比例为1:1.5(♀:♂1:1.5)。
Under the conditions of constant temperature and humidity, some biological characteristics of Toxorhynchites amboinensis were observed and studied. The mosquito developmental period: 2 days larvae 11-12 days, pupal stage 5 days. The mosquito larvae prey on 35 Aedes albopictus larvae per day. The larval period of the mosquito can be prolonged with the food intake up to 80 days. On the eighth day after emergence, adult mosquitoes lay an average of 11 grains per day. Female mosquito life of 40 days, male snake 95 days; male and female ratio of 1: 1.5 (♀: ♂ 1: 1.5).
