为协调使用杀虫剂及害虫天敌,本文测定了阿维菌素、印楝素、苦参碱、除虫菊素和吡虫啉5种常用杀虫剂分别与天敌黄瓜新小绥螨(原名胡瓜钝绥螨)对棉田朱砂叶螨的联合防治效果。结果表明:1.8%阿维菌素EW(1∶ 8 000)处理6d后释放黄瓜新小绥螨对朱砂叶螨的防治效果最佳,20d后相对防治效果高达96.63%;其次是0.3%印楝素EC(1∶250)处理7d后释放黄瓜新小绥螨,1d和20d后防效分别为59.7%和90.16%;0.5%苦参碱AS(1∶2 000)处理6d后释放黄瓜新小绥螨,20d后相对防治效果达到82.65%。本研究为朱砂叶螨可持续防控提供了可选方案,为延缓抗药性产生提供了研究思路。

To find the method for the integrated control of carmine spider mite,Tetranychus cinnabarinus and de-lay its resistance to pesticides,the joint actions of each of five commonly pesticides (abamectin,azadirachtin,ma-trine,pyrethrins and imidacloprid),and Neoseiulus cucumeris (Oudemans),the natural enemy of cotton red spi-der mite were studied.N .cucumeris was released after application of pesticides for seven days (for 0.3% aza-dirachtin EC)or six days (for other pesticides).The results showed that the combined action of 1.8% abamectin EW (1∶8 ...
