摘要

[Objective]The paper was to study the insecticidal activity and field efficacy of cyhalodiamide,a novel insecticide developed by Zhejiang Research Institute of Chemical Industry,Ltd. [Method]Toxicity of cyhalodiamide against Plutella xylostella,Spodoptera exigua,Prodenia litura and Chilo suppressalis were tested 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 LC50 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 chlorantraniliprole. 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.
