摘　　要：【目的】筛选适用于新疆喀什地区番茄潜叶蛾防控药剂,为该地区番茄潜叶蛾的防控提供理论基础。【方法】采用浸叶法,评价4种杀虫剂对番茄潜叶蛾2龄幼虫的杀虫效果,并验证其杀虫效果。【结果】番茄潜叶蛾对4种供试杀虫剂均有较高敏感性,其药剂敏感程度为0.5%苦参碱EC(0.05 mg/L)>0.3%印楝素SL(0.49 mg/L)>5%甲维盐ME(0.68 mg/L)>20%啶虫脒SP(1.27 mg/L)。番茄潜叶蛾幼虫在使用4种供试杀虫剂后防治效果显著,各药剂在药后14 d后防效均可达到90%以上。【结论】20%啶虫脒SP、5%甲维盐ME、0.5%苦参碱EC和0.3%印楝素4种杀虫剂可作为新疆喀什地区防治番茄潜叶蛾的有效药剂。【Objective】To screen the prevention and control agents suitable for Phthorimaea absoluta Meyrick in Kashgar based on the current situation of resistance of Phthorimaea absoluta Meyrick to a variety of insecticides in Kashgar,Xinjiang in the hope of providng a theoretical basis for the prevention and control of the disease in this area.【Methods】In this study,the leaf dip method was used to evaluate the insecticidal effect of four insecticides on the second instar larvae of Phthorimaea absoluta Meyrick miner,and the insecticidal effect was verified by field control experiment.【Results】The results of laboratory virulence test showed that the Phthorimaea absoluta Meyrick had a high sensitivity to the four tested insecticides,and its sensitivity was 0.5%matrine EC(0.046 mg/L)>0.3%azadirachtin SL(0.485 mg/L)>5%emamectin benzoate ME(0.681)mg/L>20%acetamiprid SP(1.265 mg/L).The control effect of four insecticides on the larvae of Phthorimaea absoluta Meyrick beetle was remarkable,and the control effect of each agent could reach more than 90%after 14 days after treatment.【Conclusion】Four insecticides,namely acetamiprid SP,5%emamectin benzoate ME,0.5%matrine EC and 0.3%azadirachtin,can be used as effective agents for the control of Phthorimaea absoluta Meyrick in Kashgar Prefecture,Xinjiang.
