是近年传入甘肃的具有重大危害性的番茄害虫，科学选用适合当地的高效番茄潜叶蛾杀虫剂，为番茄潜叶蛾应急防控及绿色防控高效精准用药提供参考依据。针对12种不同类型的杀虫剂进行了室内及田间防效评价，试验结果显示，60 g/L乙基多杀菌素、10亿PIB/mL甘蓝夜蛾核型多角体病毒、6%阿维·氯虫苯甲酰胺和10%甲维·虫螨腈室内药后第3 d幼虫死亡率为73.08%～100%，大田药后第7 d防效分别为90.26%、85.43%、83.85%、83.15%，药后14 d防效分别为80.47%、76.17%、73.89%、77.95%。综合分析，60 g/L乙基多杀菌素杀虫速效性及持效性均最佳，是番茄潜叶蛾应急防控中进行快速杀灭的理想药剂；10亿PIB/mL甘蓝夜蛾核型多角体病毒由于后期防效较好，持效期较长，是一款可作为预防性控制的生物源低毒绿色农药；6%阿维·氯虫苯甲酰胺和10%甲维·虫螨腈可作为防止抗性产生的备选轮换药剂。

The tomato leaf miner(Tuta absoluta) is a highly destructive pest that has recently been introduced to Gansu Province. This paper evaluated the efficacy of 12 different types of insecticides in both laboratory and field conditions to provide a reference for the emergency control and green control of the tomato leaf miner with efficient and precise application of pesticides.Results showed that 60 g/L Spinetoram, 1×109 PIB/mL Mamestra brassicae nuclear polyhedrosis virus, 6% Avermectins + Chlorantraniliprole, and 10% Emamectin benzoate + Chlorfenapyr achieved 73.08% to 100% larval mortality at 3 d after indoor treatment. Field control efficacy at 7 d after treatment was 90.26%, 85.43%, 83.85%, and 83.15%, respectively, and efficacy at 14 d was 80.47%, 76.17%, 73.89%, and 77.95%, respectively. The results indicated that 60 g/L Spinetoram had the best speed and persistence of insecticidal effect and was an ideal insecticide for rapid killing in emergency control of the tomato leaf miner. 1×109 PIB/mL Mamestra brassicae nuclear polyhedrosis virus had a better control effect in the later stage and a longer persistence period, making it a low-toxicity and green biopesticide suitable for preventive control. 6% Avermectins + Chlorantraniliprole and 10% Emamectin benzoate + Chlorfenapyr could be used as alternative rotation insecticides to prevent the development of resistance.
