摘要/Abstract

摘要： 本文报道了发生在四川雅安的网纹绵蚧Chloropulvinaria polygonata (Cockerel)寄生蜂共有6种,其中以黑色软蚧蚜小蜂Coccophagus yoshidae Nakayama和白蜡虫花翅跳小蜂Microterys ericeri为优势种群。寄生蜂对网纹绵蚧有较高的寄生率,4~5月中旬,对雌蚧寄生率达36.9%~44.7%,对雄蚧寄生率达2.3%~8.62%。4种杀虫剂对寄生性天敌的毒性试验表明:氧化乐果和稻虱净对寄生蜂的毒性较小。

关键词: 网纹绵蚧, 寄生蜂, 杀虫剂

Abstract: There are six species of parasitic wasps of Chloropulvinaria polygonata (Cocrerell) in Yaan, Sichuan Province. The dominant populations are Coccophagus yoshidae Nakayama and Microterys ericeri Ishii. The parasitic rate of the females by these wasps reaches 36.9% to 44.7%, and that of the males is 2.3% to 8.62% from April to the middle of May, respectively. The test of toxicity of five kinds of insecticides on the parasitic wasps shows that the toxicity of Dimethoxidae and quinalphos on the natual enemies are lower than that of other insecticides.

Key words: CHLOROPULVINARIA POLYGONATA, PARASITIC WASP, INSECTICIDE
