Reproduction and biological characteristic of Chouioia cunea

摘要

Chouioia cunea Yang is a natural enemy for many kinds of crop and forest pests, particularly for Hyphantria cunea Drary, which is an international quarantine pest. The experiment of rearing Chouioia cunea with Tussah (Silkworm) pupa were carried out by "three-cut method" and inoculating method. The results showed that three-cut method is effective way for breeding Chouioia cunea, with a parasitical rate of 95%. The biological characteristics and the life cycle of Chouioia cunea were observed and described and more hosts of Chouioia cunea were found. "Three-cut method" as a new technique of rearing Chouioia cunea has been put into practice.
