平腹小蜂(Anastatus sp. )是防治荔枝蝽象的卵寄生蜂。羽化后成虫寿命较长,若喂养糖液成虫可存活一个月以上,但若不供给食物,则羽化后成虫只活3～7天,可见成虫寿命与食物有密切关系,亦说明在平腹小蜂成虫中存在完善的消化系统。故对该蜂的消化系统进行了形态、组织学的研究,并对中肠进行了亚显微结构研究。为室内繁蜂和饲养提供理论依据。 Anastatus sp. Is an egg parasitic wasp that controls litchi stinkbug. After emergence, adult life is longer, if the adult sugar-fed adult worms can survive more than a month, but if not provided food, adult adults only live 3 to 7 days after emergence, we can see that adult life and food are closely related, There is a perfect digestive system in bee adults. Therefore, the bee digestive system morphology, histology, and the midgut sub-microstructure research. For indoor bumble bee and feeding provide a theoretical basis.
