为了开展红铃虫的生物防治工作,从1977年开始我们对上海郊区棉红铃虫的天敌资源进行了调查。1977和1978两年着重调查了幼虫的寄生性天敌。现将结果报导如下。一、种类两年来于5～9月在10个郊县采集田间幼虫样本,取回室内按条放入指形管内,在室温下观察寄生情况。到1978年年底为止共收集到幼虫寄生性天敌9种,它们是黄胸茧蜂 Bracon isomera,黑胸茧蜂 B.nigrorufum,红铃虫茧蜂 Habrobracon Pe-ctinophorae,长须茧蜂 Microdus sp,绒茧蜂Apanteles sp,中国齿腿姬蜂 Pristomerus chi-
In order to carry out the biological control of pink bollworm, from 1977 we investigated the natural enemies of pink bollworm in the suburbs of Shanghai. In 1977 and 1978, the parasitic natural enemies of larvae were investigated. The results are reported below. I. Species In the past two years, field larvae samples were collected in 10 suburbs from May to September. The samples of the field larvae were retrieved and placed into the finger-shaped tubes. The parasitism was observed at room temperature. By the end of 1978, 9 species of larvae parasitic natural enemies were collected, namely Bracon isomera, B.nigrorufum, Habrobracon Pe-ctinophorae, Microdus sp, velvet Apanteles sp, Chinese Prickly-frog Pristomerus chi-
