摘　　要：[目的]评价5%TXH09水分散粒剂(WG)对棉铃虫和红铃虫的田间防治效果。[方法]采用叶面喷雾法。[结果]5%TXH09WG能够有效地降低棉铃虫和红铃虫的虫口密度,减轻害虫对棉花和辣椒的为害,具有较好的持效性,同时对棉花和辣椒具有很好的保蕾铃或保果效果,没有产生药害现象。在同等有效剂量下,5%TXH09WG和5%氟铃脲乳油(EC)对害虫防效及保蕾铃或保果效果基本一致,2者间无显著差异。[结论]5%TXH09WG是防治棉铃虫和红铃虫的高效杀虫剂。[Aims] This study aims to evaluate the field efficacy of TXH09 5% water dispersible granules(WG) in controlling cotton bollworm(Helicoverpa armigera) and pink bollworm(Pectinophora gossypiella). [Methods] Foliar spray method was used. [Results] TXH09 5% WG showed an effective and persistent effect in decreasing the numbers of the two bollworms larvae and mitigating their damage to cotton and pepper plant. It also revealed good effect on the preservation of cotton bolls and pepper fruit accompanying with unobserved hazard. When TXH09 5% WG and hexaflumuron 5% EC were used at the same active dosage, they showed the same good effect on pest control and preservation, and there were no significant difference between the efficacies of TXH09 and hexaflumuron.[Conclusions] TXH09 5% WG is a potential agent to be used effectively against cotton bollworm and pink bollworm.
