摘要
[目的]筛选高效低毒药剂防治入侵安徽省的草地贪夜蛾。[方法]评价了6种药剂对入侵安徽草地贪夜蛾种群的室内杀虫活性和田间防效。[结果]5%甲氨基阿维菌素苯甲酸盐微乳剂室内杀虫活性最高、田间防效最好,48 h的LC50值为0.070 mg/L,7、14 d的大田防效分别达到91.90%和92.78%;其次是60 g/L乙基多杀菌素悬浮剂和20亿PIB/mL甘蓝夜蛾核型多角体病毒悬浮剂,而8000 IU/μL苏云金杆菌悬浮剂、80亿cfu/mL金龟子绿僵菌CQ-Ma421可分散油悬浮剂和100亿cfu/g白僵菌原粉粉剂对安徽草地贪夜蛾的室内杀虫活性和田间防效均较低。[结论]在安徽地区,可选用甲氨基阿维菌素苯甲酸盐、乙基多杀菌素和甘蓝夜蛾核型多角体病毒对草地贪夜蛾进行防治。
[Aims]This paper aims to screen out effective insecticides with good control effects to Spodoptera frugiperda in Anhui province.[Methods]The indoor toxicity and field efficacy of six insecticides to S.frugiperda were evaluated.[Results]The indoor toxicity and field efficacy of the emamectin benzoate 5%ME were the highest with LC50 value of 0.070 mg/L after 48 h treatment and 91.90 and 92.78%control in field after 7 and 14 days treatment respectively.Followed by the spinetoram 60 g/L SC and cabbage armyworm nuclear polyhedrosis virus 2×10^9 PIB/mL SC,but the indoor toxicity and field efficacy of other three insecticides to S.frugiperda were all lower,including Bacillus theuringiensis 8000 IU/μL SC,Metarhizium chager CQ-Ma4218×10^9 cfu/mL OD and Beauveria bassiana 1×10^10 cfu/g OP.[Conclusions]Emamectin benzoate,spinetoram and cabbage armyworm nuclear polyhedrosis virus could be selected for controlling S.frugiperda in Anhui province.
