| 摘 要： | 协调使用杀虫剂及害虫天敌,该文测定了阿维菌素、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6 d后释放黄瓜新小绥螨对朱砂叶螨的防治效果最佳,20 d后相对防治效果高达96.63%;其次是0.3%印楝素EC(1∶250)处理7 d后释放黄瓜新小绥螨,1和20 d后防效分别为59.7%和90.16%;0.5%苦参碱AS(1∶2 000)处理6 d后释放黄瓜新小绥螨,20 d后相对防治效果达到82.65%。该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。

| Abstract: | To find the method for the integrated control of Tetranychus cinnabarinus (carmine spider mite) and delay its resistance to pesticides,the joint actions of each of five commonly pesticides (abamectin,azadirachtin,matrine,pyrethrins and imidacloprid),and Neoseiulus cucumeris (Oudemans),the natural enemy of cotton red spider mite,were studied.N.cucumeris was released after application of pesticides for seven days (for 0.3％ azadirachtin EC) or six days (for other pesticides).The results showed that the combined action of 1.8％ abamectin EW (1∶8 000) and N.cucumeris had the best control efficacy of 96.63％ at 20 days after N.cucumeris releasing.The control efficacies of N.cucumeris and 0.3％ azadirachtin EC (1∶250) were 59.7％ and 90.1％ after one day and 20 days,respectively,after N.cucumeris releasing.The control efficacy of N.cucumeris and 0.5％ matrine AS (1∶2 000) was 82.65％ at 20 days after N.cucumeris releasing.The results provide options for sustainable control of T.cinnabarinus and for the delay of pesticides resistance. |
