摘　　要：为了探究杀虫剂对玉米大豆带状复合种植大豆田甜菜夜蛾的防治效果,选取9种杀虫剂开展药剂筛选试验,结果表明,各处理试验药剂对大豆植株安全;喷施6%乙基多杀菌素SC 450 mL/hm^(2)、20%多杀霉素SC 450 mL/hm^(2)、5%溴虫氟苯双酰胺SC 450 mL/hm^(2)对玉米大豆带状复合种植大豆田甜菜夜蛾具有较好的防治效果,药后1 d对大豆田甜菜夜蛾的防效均达65%以上,药后3 d均达85%以上,药后7 d均达90%以上。以上3种处理药剂防治效果显著高于其他药剂处理,且这3种药剂处理药效迅速,可在短时间内显著减少甜菜夜蛾的种群数量。该研究监测了2022年8月滨淮农场地区甜菜夜蛾发生情况,为玉米大豆带状复合种植大面积生产科学防控甜菜夜蛾提供依据。In order to investigate the effect of insecticides on the control of Spodoptera exigua in corn-soybean banded composite planting soybean fields,nine kinds of insecticides were selected to carry out the screening test,and the results showed that the test agents of the treatments were safe for soybean plants;the spraying of 6%ethyl polymyxin SC 450 mL/hm^(2),20%polymyxin SC 4mL/hm^(2),5%broflanilide SC 450 mL/hm^(2)had a better control effect on the Spodoptera exigua in corn-soybean banded composite planting soybean fields,the prevention effect reached 65%1 d after the drug.3 d after the drug reached more than 85%,7 d after the drug reached more than 90%.The control effects of the above three treatments were significantly higher than those of other treatments,and the three treatments had rapid efficacy,which could significantly reduce the population size of the Spodoptera exigua in a short period of time.This study monitored the occurrence of Spodoptera exigua in Binhuai farm area in August 2022,which provides a basis for scientific prevention and control of Spodoptera exigua in large-scale production of corn-soybean banded compound planting.
