不同药剂对辣椒斜纹夜蛾的防治效果

为了解不同杀虫剂对辣椒斜纹夜蛾的敏感性,并提供防治指导,将10种杀虫剂进行田间药效试验。结果表明:667 m^2用5%氯虫苯甲酰胺悬浮剂75.00、60.00 mL,667 m^2用20%虫酰·茚虫威悬浮剂65.00、57.50、50.00 mL,667 m^2用19%溴氰虫酰胺悬浮剂60.00、40.00 mL,667 m^2用10亿PBI/mL斜纹夜蛾核型多角体病毒悬浮剂120.00、85.00、60.00 mL对辣椒斜纹夜蛾具有较高的敏感性,药后3 d和8 d防效均在90%以上;667 m^2用3%甲氨基阿维菌素苯甲酸盐微乳剂7 mL、667 m^2用1.8%阿维菌素乳油60.00 mL、667 m^2用19%溴氰虫酰胺悬浮剂30.00 mL和667 m^2用5%高效氯氟氰菊酯水乳剂25.00、20.00 mL对斜纹夜蛾有较好的敏感性,药后3 d和8 d防效在70%以上;300亿孢子/g球孢白僵菌可分散油悬浮剂、16 000 IU/mg苏云金杆菌可湿性粉剂、60 g/L乙基多杀菌素悬浮剂对斜纹夜蛾的敏感性较差。

Control Effect of Different Insecticides on Prodenialitur alitura of Pepper

Abstract: In order to understand the sensitivity of different insecticides to Prodenialitur alitura and provide guidance for control, 10 insecticides were tested in the field. The results showed that 5% chlorantraniliprole suspension concentrate with 75.00, 60.00 mL per 667 m2, 20% pyrenyl-ninhydrin suspension concentrate with 65.00, 57.50, 50.00 mL per 667 m2, 19% cyantraniliprole suspension concentrate with 60.00, 40.00 mL per 667 m2 and 1 billion PBI/mL spodoptera litura nucleopolyhedro virus suspension concentrate with 120.00, 85.00, 60.00 mL per 667 m2 had high sensitivity to Prodenialitur alitura , whose control effects were above 90% at 3 and 8 days after medication. 3% aminoavermectin benzoate microemulsion with 7 mL per 667 m2, 1.8% abamectin emulsion with 60 mL per 667 m2, 19% cyantraniliprole suspension concentrate with 30 mL per 667 m2, and 5% high-efficiency cypermethrin emulsion with 25.00, 20.00 mL per 667 m2 had better sensitivity to Prodenialitur alitura , all of their control effects were above 70% at 3 and 8 days after medication. The sensitivity of 30 billion spores/g beauveria bassiana dispersible oil suspension, 16 000 IU/mg bacillus thuringiensis wettable powder and 60 g/L ethyl-multi bactericide suspension had poor sensitivity to Prodenialitur alitura .
