摘要/Abstract

摘要： 1978～1982年,在成都调查水稻二化螟寄生性天敌,寄生蜂有19种,优势种为稻螟赤眼蜂、螟甲腹茧蜂、稻螟小腹茧蜂、夹色姬蜂和大螟钝唇姬蜂。卵粒寄生率第一代为2.63％,二代40.73％,三代85.54％;幼虫寄生率一代为28.30％,主要寄生于3～5龄幼虫体内,3龄寄生率为28.57％,4龄55.56％,5龄33.33％,蛹寄生率一代为56.25％,二代57.53％,越冬代8.82％。对二化螟有一定的控制作用。本文还就化学农药对寄生蜂的影响进行了分析。

Abstract: Nineteen species, representing 3 families, of parasites of rice stem borer, Chilo suppressalis Walker were found in the oaddies of Chengdu area during 1978 to 1982. Trichogramma japonicum. Chelonus aunakatae, Microgastet russata, Centeterues alternecoloratus, and Eriborus terebrans were the predominant species. Egg parasitization of the 1st, 2nd, and 3rd generation rice stem borers were 2.63%, 40.73%, and 85.54%, respectively. Parasitization of the 1st generation larvae was found mainly in the 3rd to 5th instars. It was 28.571, 55.56% and 33.33% for the 3rd, 4th and 5th instars, respectively. Pupal parasitization was over 50% for the 1st and 2nd generation, but 8.82% for the overwintering generation. Effects of chemical pesticides oh the parasites was also discussed.
