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 %
The effects of insecticides on controlling midges in the three aspects of the effects of chemical pesticides on the farmland ecosystem, the control effect of plant insecticides on the inhalers and the protection to natural enemies were studied from the aspects of the control of Sitodiplosis mosellana Gehin effect. The results showed that application of plant-based insecticides not only had a good control effect on midge, but also reduced the impact of chemical pesticides on farmland ecosystems. Among them, 29% Better, the control effect on adults up to 77.7% ~ 90.1%
