1977年我们在天敌资源调查时,发现黑胸茧蜂寄生红铃虫幼虫,而且自然寄生率较高。为了摸清黑胸茧蜂的形态特征、生物学特性及人工繁殖技术,以便发挥它在生物防治中的应有作用,1978—1979年我们进行了室内外观察试验,现将结果初报如下。 一、形态特征 黑胸茧蜂 Bracon nigrarufum(Cushman)属膜翅目茧蜂科。
In 1977, when we investigated the natural enemy resource, we found that the black-billed bee had parasitized the red bollworm larvae and had a high natural parasitic rate. In order to find out the morphological characteristics, biological characteristics and artificial propagation techniques of C. elegans, in order to play its due role in biological control, we conducted indoor and outdoor observation tests from 1978 to 1979, and the results are as follows. First, the morphological characteristics of black brazilian bee Bracon nigrarufum (Cushman) is a Hymenoptera bradyenidae.
