5种杀虫剂对筛豆龟蝽的田间防治效果评价
Evaluation of Field Control Efficacy of Five Insecticides against Megacopta cribraria
摘要
Abstract
In order to screen out highly effective insecticides for the control of Megacopta cribraria,a field efficacy test was conducted on M.cribraria in the soybean-maize strip intercropping fields using five commonly used insecticides.The test results showed that 3 days after application,imidacloprid 70%WG exhibited the highest control effect(72.66%),followed by deltamethrin 2.5%EC(70.84%),while the control effects of other insecticides were not satisfactory.At 7 days post-treatment,deltamethrin 2.5%EC achieved the best control effect(81.38%),followed closely by imidacloprid 70%WG(80.56%).Both were significantly more effective than the other treatments.Based on these findings,deltamethrin 2.5%EC and imidacloprid 70%DWG are recommended as emergency insecticides options for M.cribrariacontrol.关键词
