植物性杀虫剂防治小麦吸浆虫研究

Studies on Controlling of Botanical Insecticides to Wheat Blossom Midge

从防治小麦吸浆虫 ( Sitodiplosis mosellana Gehin)施用化学农药对农田生态系统的影响、植物性杀虫剂对吸浆虫的防效和对天敌的保护作用三方面研究了植物性杀虫剂在小麦吸浆虫防治中的作用。结果表明 ,在小麦吸浆虫防治中 ,应用植物性杀虫剂 ,不仅对吸浆虫有较好的防效 ,而且可减少化学农药对农田生态系统的影响 ,其中 ,2 9%净叶宝对吸浆虫的效果较好 ,对成虫的防效可达 77.7%～ 90 .1 %

This study is mainly about the influence of chemical pesticide to field eco system, control effect and protection role to natural enemies of wheat blossom midge by using botanical pesticide in agricultural practice. The results show that botanical pesticide can not only effectively control wheat blossom midge, but also may reduce influence of chemical pesticide to field eco system. The control effect of 29% Jing yebao EC, a newly explotied botanical pesticide, is well in this test, from 77.7% to 90.1% to adult of wheat blossom midge.
