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。
Coordinated use of insecticides and natural enemies of pests, five commonly used insecticides, abamectin, azadirachtin, matrine, pyrethrin and imidacloprid, ) On the control of Tetranychus cinnabarinus in cotton field. The results showed that the best cucumber spider mite control was released after 1.8% avermectin EW (1: 8 000) treatment for 6 days and the relative control effect was 96.63% after 20 days; followed by 0.3% Azadirachtin (1: 250) treatment for 7 d released the cucumeris cucumbers 1 and 20 d after the control effect was 59.7% and 90.16%; 0.5% matrine AS (1: 2000) for 6 d After the release of cucumbers new cucumbers, 20 d after the relative control effect reached 82.65%. The study provided an alternative solution for the sustainable prevention and control of Tetranychus cinnabarinus and provided a research idea for delaying the emergence of drug resistance.
