摘要
为筛选出防效较好的杀虫剂用于大庆地区蝗虫的防治,采用笼罩式方法,应用印楝素乳油、阿维菌素、丁烯氟虫腈乳油、氰戊菊酯和阿维·苏云菌共5种杀虫剂对大庆地区草原蝗虫进行了田间药效对比试验。结果表明:药后3d,阿维·苏云菌和印楝素防效为56.0%和60.0%,其余防治效果均高于76.0%。药后12d,阿维·苏云菌防效达到82.9%,其余4种杀虫剂均达到100.0%。说明化学杀虫剂作用效果迅速,生物杀虫剂作用效果缓慢,应根据蝗虫的发生情况选择适宜的药剂进行防治。
In order to screen out the better insecticide against grassland locust in Daqing ,the efficiency of Avi Su Yunjun ,Azadirachtin ,Butene fipronil EC ,Fenvalerate and Avermectin against locust were compared by hanging method in Daqing .The results showed that 3 days after medieation ,the control efficiencies of Avi Su Yunjun and Azadirachtin were 56 .0% and 60 .0% ,and other insecticides were above 76 .0% .After 12 days for medica-tion ,the efficiency of Avi Su Yunjun reached 82 .9% ,other four insecticides attained 100 .0% .It illustrated that the efficiency of chemical insecticides was quick ,the efficiency of biological insecticides was slow ,suitable insec-ticides should be selected on the basis of situation to control grassland locusts .
