摘　　要：为了筛选出防治甘薯田蛴螬的理想药剂,以优质鲜食型甘薯新品种齐宁18号为试材,在蛴螬严重发生的甘薯试验田选用辛硫磷、氟虫腈、苦参碱、绿僵菌和白僵菌等药剂对蛴螬进行防治试验。结果表明,在甘薯栽秧时穴施10%吡虫啉微胶囊剂或5%氟虫腈悬浮剂,均对蛴螬具有良好的防治效果,10%吡虫啉微胶囊剂用药量4500和6750 mL/hm 2时,对蛴螬的防治效果分别为71.93%和85.96%,显著高于其他药剂,且显著提高了甘薯的商品率。经农药残留检测部门检测,试验所用药剂均在甘薯薯块中无残留。In order to screen out the effective insecticides against white grubs in sweetpotato fields,the control efficacy of phoxim,fipronil,matrine,Metarhizium anisopliae and Beauveria bassiana on white grubs was evaluated in the sweetpotato fields where grubs occured seriously and Qining 18 cultivar were planted.The results showed that in the treatments of imidacloprid 10%CJ or fipronil 5%FS dibble application before planting sweet potato seedlings had good control efficacies.The control efficacies of imidacloprid 10%CJ(4500 and 6750 mL/hm 2)on sweet potato grubs was 71.93%and 85.96%respectively,which were significantly higher than that of other pesticides,and the quality of sweet potato was significantly improved.No insecticide residue was detected by the pesticide residue detection department in the sweet potato produced in all treatments and all the insecticides were safe for sweetpotato production.
