摘　　要：本试验选用3.6%烟碱·苦参碱乳油、25%阿维·灭幼脲悬浮剂和20亿PIB/mL棉铃虫核型多角体病毒悬浮剂3种无公害农药开展美国白蛾幼虫防治。结果表明:药后15 d,2.50×10^(6)PIB/mL、4.25×10^(6)PIB/mL和1.25×10^(7)PIB/mL棉铃虫核型多角体病毒悬浮剂对美国白蛾的防治效果均达到91%以上;药后9 d,3.6%烟碱·苦参碱乳油3000倍液对美国白蛾的防治效果达100.00%;药后15 d,25%阿维·灭幼脲悬浮剂1000倍液和1500倍液对美国白蛾的防治效果均达到98%以上。3种农药对美国白蛾的防治效果均较好。其中,棉铃虫核型多角体病毒对鱼虾安全,可在鱼虾养殖等水域美国白蛾防治中大面积应用推广。This study conducted a control test on Hyphantria cunea(Drury)using three pollution-free pesticides(3.6%nicotine·matrine EC,25%abamectin·chlorbenzuron SC and 2 billion PIB/mL HaNPV SC).The results showed that on the 15th day after application,the control effects of HaNPV SC with concentrations of 2.50×10^(6)PIB/mL,4.25×10^(6)PIB/mL and 1.25×10^(7)PIB/mL on Hyphantria cunea reached over 91%.On the 9th day after application,the control effect of 3.6%nicotine·matrine EC 3000 times on Hyphantria cunea reached 100.00%.On the 15th day after application,the control effects of 25%abamectin·chlorbenzuron SC 1000 and 1500 times on Hyphantria cunea reached over 98%.All three pesticides have good control effects on Hyphantria cunea.Among them,the HaNPV was safe for fish and shrimp,and could be widely applied and promoted in the prevention and control of Hyphantria cunea in water areas such as fish and shrimp farming.
