摘  要：
通过4年的调查研究,在辽宁省沈阳和吉林省延吉两地发现天幕毛虫(Malacosoma neustria testaceaMotschulsky)卵的寄生蜂共6种:天幕毛虫黑卵蜂〔Telenomus terbraus(Ratzeburg)〕、毒蛾黑卵蜂(暂拟)(Telcnomus sp.)、大蛾卵跳小蜂〔Gocncyrtus Kuwanae(Howard)〕、斑角跳小蜂〔O.masii(Merc.)〕、舞毒蛾卵平腹小蜂〔Anastatus disparis(Rusch.)〕、松毛虫赤眼蜂(Trichogramma dendrolimi Matsumura)。其中在天幕毛虫卵内越冬者有4种,寄生率为13.6%—18.0%,以天幕毛虫黑卵蜂及大蛾卵跳小蜂为优势种;当年世代有4种,寄生率为7.1%—11.3%,以大蛾卵跳小蜂及舞毒蛾卵平腹小蜂为优势种

摘  要：
The investigation was conducted in the last four years.Six parsitic wasps species were found parasitizing the eggs of tent caterpillar(Mal- acosoma neustria testacea Motschulsky)in Shenyang(Liaoning province)and Yanji(Jilin Province).They were Telenomus terbratus(Ratzeburg); Telenomus sp.;Ooencyrtus masii(Merc.);Ooencyrtus Kuwa ai(Howard); Anastatus disparis(Rusch.);Trichogramma dendrolimi Mat(?)mra; Among these,four species overwintered in the eggs of tent caterpillar; their total yearly natural parasitization rate was about 13.6%～32.3%. Both telenomus terbratus and Ooencyrtus kuwanai were dominant species; the parsasition rate of the current generation of the former was 6.3%～ 18.0% of the total rate,arid that of the latter 14.3%～90.0% respectively. Four species completed their life cycle in one year.Their total par- asitization rate was about 7.1%～11.3%.Ooencyrtus kuwanai and Anastatus disparis were dominant species too,their parasitization rates of the cur- rent generation reached 56.1% their parartization rates of the current gener- ation reached 56.1% and 36.9% of the total rate respectively. The present paper reports on the life cycle,overwintering pattern, characteristicsof parasitism,length of the developmental period,emergence rate,sex ratio,life span of the adults and mass breeding tests.
