[ Method] Toxicity of cyhalodiamide against Plutella xylostella, Spodoptera exigua, Prodenia litura and Chilo suppressalis were tasted in the laboratory by leaf-dipping method, and the field efficacy of cyhalodiamide against P. xylostella, S. exigua, P. litura, Pieris rapae, C. suppressalis and Cnaphalocrocis medinalis was evaluated. [ Result] The LCs0 values of cyhalodiamide against P. xylostella, S. exigua, P. litura and C. suppressalis were 0. 046, 0.072, 0.071 and 1.95 mg/L, respectively, almost equivalent to that of flubendiamide and ehlorantraniliprole. The control efficacy of 20% Z4042 SC （30 g/hm2） against P. xylostella, S. exigua, P. litura and P. rapae was 90.1% - 96.3 % after spraying for 7 d, and its control efficacy against C. suppressalis and C. medinalis was 82.9% -90.5% after spraying for 15 d. No crop injury was observed at the test dosage. [Conclusion] The study provided reference for field control against Lepidoptera pests.展开更多
