Field Efficacy Trials of Afidopyropen against Aphidoidea

[目的]评价新型杀虫剂5%双丙环虫酯可分散液剂对黄瓜蚜虫的田间防效。[方法]分别于2016、2017年进行田间药效试验。[结果]5%双丙环虫酯可分散液剂7.5~12.5 g a.i./hm^2对黄瓜蚜虫防效显著,药后3 d防效达94.33%~98.32%,药后7 d防效为92.07%~96.20%,持效期可达14 d左右。[结论]5%双丙环虫酯可分散液剂可作为防治黄瓜蚜虫的高效低毒药剂应用推广。

[Aims] This study aims to evaluate the field efficacy of a new insecticide afidopyropen against Aphidoidea. [Methods] Field trials were conducted in 2016 and 2017. [Results] Afidopyropen 5% DC were effective on Aphidoidea at 7.5-12.5 g a.i./ha, the control effect was 94.33-98.32% at 3th day after treatment, the control effect was 92.07-96.20% at 7th day after treatment, and the efficacy could last for 14 days. [Conclusions] Afidopyropen 5% DC can beused as a high efficacy and low toxicity pesticide for control of Aphidoidea.
