蚜茧蜂是蚜虫的重要天敌之一,我省在这一方面记载甚少。1981年程法曾等曾对我省麦田中所发生的蚜茧蜂作了报道(河北农学报1981年第一期),提出我省麦田中的蚜茧蜂有5种。但作者当时并未作出鉴定,所述生物学特性也未指明系何种蚜茧蜂。我们从1979年开始,在河北几个地区进行了蚜茧蜂调查。三年多来,共发现蚜茧蜂十余种,其中,寄生于小麦蚜虫:麦长管蚜Macrosiphum avenae(F),黍缢管蚜Rhopalosi-
Aphid Braconidae is one of the important natural enemies of aphids, the province recorded little in this regard. In 1981, Cheng et al.

We started in 1979, conducted a survey of aphid bee in several areas in Hebei. More than three years, a total of more than ten kinds of aphid bees were found, among them, the wheat aphids parasitized: Macrosiphum avenae (F), Rhopalosi-
