摘　　要：浙江栉蝠蛾Bipectilus zhejiangensis Wang是我国南方地区重要的竹林地下害虫，其生物学特性尚未见报道。通过林间调查和室内试验对浙江栉蝠蛾危害竹子种类及生物学特性进行较为系统的观察。结果表明，浙江栉蝠蛾危害竹子种类多，主要以刚竹属竹种为主。浙江栉蝠蛾在浙江省1年发生1代，以2～3龄幼虫在土壤中越冬，翌年4月上旬幼虫开始化蛹，5月初成虫开始羽化，羽化主要集中在13：30～18：30之间，羽化当天便可交尾产卵，单雌平均产卵量可达290粒，成虫寿命雌虫平均4．2d，雄虫平均6．2d。卵经70d左右孵化，随即钻入土壤取食，准备越冬。Bipectilus zhefiangensis Wang is one of the important soil insects that damage bamboo shoots in South China, and its biological characteristics are still unclear. The host species and biological characteristics of B. zhejiangensis was systematically investigated and studied both in field and in laboratory. The resuhs showed that more than 20 species of bamboo could be damaged by B. zhejiangensis, most of which belonged to the genus of Phyllostachys. There was one generation of B. zhejiangensis in Zhejiang Province, and it overwintered as larvae of the 2nd - 3rd instar, Larvae began to pupate in early April. Adults started to emerge in early May, and mainly emerged between 13：30 - 18：30. The average longevity of adults was about 4.2 d for female, and about 6.2 days for male. The average fecundity was about 290 per female, and eggs began to hatch about 70 days later after oviposition. After hatched, larvae got into the soil for feeding and overwintering.
