Influence on the Main Natural Enemies about Several Insecticide in Rice Field

通过测定稻田主要杀虫剂醚菊酯、氟虫腈、吡虫啉、噻嗪酮及敌敌畏5种药剂对稻田主要天敌蜘蛛及赤眼蜂的影响作用,对比了各药剂在持效期内对天敌的毒杀作用强弱,天敌生物的人工释放应避开这些药剂施用期。

We detected the influence of the main insecticide like ethofenprox, fipronil, imidacloprid, buprofezin, DDVP on spiders and trichogramma, and compared their toxic action. The results told us that natural enemies should be away from the period of releasing.
