摘　　要：为明确新化合物氟氧虫酰胺(ZJ3757)的杀虫活性,采用浸叶法测定了其对小菜蛾Plutella xylostella、斜纹夜蛾Prodenia litura和甜菜夜蛾Spodoptera exigua的毒力,得其LC50值分别为0.088、0.905和0.095 mg/L,与氯虫苯甲酰胺和氟虫双酰胺的杀虫毒力相当。田间试验结果表明,20%氟氧虫酰胺悬浮剂(SC)在有效成分15 g/hm2剂量下对小菜蛾、甜菜夜蛾、斜纹夜蛾和菜青虫Pieris rapae药后7 d的防效分别达88.41%、92.72%、82.07%和98.39%,与氯虫苯甲酰胺相当,高于或相当于氟虫双酰胺、茚虫威和甲氨基阿维菌素的防效。可考虑将氟氧虫酰胺用于蔬菜上小菜蛾、斜纹夜蛾、甜菜夜蛾和菜青虫的防治。Toxicity of novel compound ZJ3757 against Plutella xylostella, Prodenia litura and Spodoptera exigua were tested by leaf dip bioassay. The LCs0values were 0.088,0. 905 and 0.095 mg/L, respectively, which were almost equivalent to that of chlorantraniliprole and flubendiamide. Field trials showed that the control efficacy of 20% ZJ3757 SC against P. xylostella ,S. exigua ,P. litura and Pieris rapae were 88.41%, 92.72%, 82.07% and 98.39%, respectively, after seven days treatment at the dosage of 15 g a. i./hm2, which were equivalent to that of chlorantraniliprole, higher or equivalent to that of flubendiamide, indoxacarb and emamectin benzoate. The results suggested ZJ3757 is a new insecticide effective against P. xylostella,P, litura, S. exigua and P. rapae on vegetables.
