摘　　要：为了探明唑虫酰胺用于防治甘蓝田常见害虫的可行性和合适剂量,参照《农药田间药效试验准则》相应方法测定了30%唑虫酰胺悬浮剂对小菜蛾、黄条跳甲和蚜虫的防治效果。2018年和2019年试验中30%唑虫酰胺悬浮剂90、112.5 g/hm^(2)对小菜蛾药后7天防效达85.63%、89.17%和88.54%、91.34%,略高于或显著高于1.8%阿维菌素乳油13.5 g/hm^(2);该两处理对蚜虫药后7天的防效达79.67%、88.03%和83.28%、90.16%;而112.5 g/hm^(2)处理2天对黄条跳甲成虫的防效为74.91%、72.54%,显著高于5%啶虫脒乳油45 g/hm^(2)。30%唑虫酰胺悬浮剂90~112.5 g/hm^(2)能较好的控制甘蓝小菜蛾、黄条跳甲和蚜虫的为害。The aim of this study is to investigate the feasibility and appropriate dose of tolfenpyrad in controlling common insect pests in cabbage fields.According to Pesticide Guidelines for the Field Efficacy Trials,we determined the control effects of 30%tolfenpyrad SC on Plutella xylostella,Phyllotreta striolata and Brevicoryne brassicae.The results showed that,the control effects of 90 g/hm^(2) and 112.5 g/hm^(2) 30% tolfenpyrad SC on P.xylostella at 7 days after treatment(DAT)were 85.63%and 89.17%in 2018 trials,and 88.54%and 91.34%in 2019 trials,which were higher or significantly higher than that of 13.5 g/hm^(2) 1.8% abamectin EC.At 7 DAT,the above two treatments showed 79.67%and 88.03%control effects on B.brassicae in 2018 trials,and 83.28%and 90.16%control effects in 2019 trials.At 2 DAT,the treatment of 30%tolfenpyrad SC 112.5 g/hm^(2) showed 74.91%and 72.54%control effects on P.striolata in 2018 and 2019 trials,respectively,which were significantly higher than that of 45 g/hm^(2) 5% acetamiprid EC.This study proved that P.xylostella,P.striolata and B.brassicae could be well controlled by 90-112.5 g/hm^(2) 30% tolfenpyrad SC.
