摘　　要：[目的]旨在明确不同药剂对马铃薯蛴螬的防治效果及果实防效,并确定施药时期和用量。[方法]选择1%氯虫苯甲酰胺·氟氯氰菊酯颗粒剂、2%噻虫胺·氟氯氰菊酯颗粒剂、2%噻虫胺·嘧菌酯颗粒剂、0.5%噻虫嗪颗粒剂4种药剂,采用撒施法进行田间试验。[结果]在所选4种药剂中,2%噻虫胺·氟氯氰菊酯颗粒剂的防治效果最好,300、375、450 g a. i./hm^(2)的防治效果分别为89.00%、91.32%、92.87%。且有效成分450 g a.i./hm^(2)处理的果实防效达到91.84%。[结论]2%噻虫胺·氟氯氰菊酯颗粒剂具有快速、高效、对作物安全的特点,可用于马铃薯蛴螬的防治。[Aims] The aim was to determine the control effect of different insecticides on potato grubs and the fruit control effect, and to determine the application period and dosage. [Methods] The field experiment was carried out using chlorandiamide·cyhalothrin 1% granules, clothianidin·cyhalothrin 2% granules, clothianidin·pyrimethanil 2%granules and thiamethanidam 0.5% granules four kinds of insecticides by spraying application. [Results] Among the four selected agents, clothianidin· cyhalothrin 2% granules had the best control effect, and the control effect of 300,375 and 450 g a.i./ha were 89.00, 91.32 and 92.87%, respectively. The control effect of fruit treated with 450 g a.i./ha reached 91.84%. [Conclusions] Clothianidin-cyhalothrin 2% granules are fast, efficient and safe to crops, and can be used for the control of potato grubs.
