摘要

Approaches of studies on the chestnut gall wasp, Dryocosmus kuriphilus Yasumatsu in China were documented in this paper. The pest distributes over 16 provinces covering all the chestnut productive area in the country with yield damage 15-30% every year. It was observed only 1 generation each year and seems to reproduce by parthenogenesis. Over wintering as young larvae within the host buds, it feeds acting with the budburst in spring, and its cabin forms with the leaf growth and spread. The adult eclosion is at end of male flower blooming. There have been 28 parasitical wasps reported as the nature enemies of the pest up today. Among them, Torymus sinensis Y. is the most predominant one. Pollarding in winter, releasing natural enemy during April to June, using black light trap from June to September, and utilizing resistant cultivars are the main methods of IPM.
