摘　　要：为了检验不同的杀虫剂混配对沟金针虫的毒力效果,本研究采用浸渍法测定5种单剂及各复配药剂对沟金针虫的毒力。通过使用共毒因子法和共毒系数法,一共筛选出11组共毒因子高于20的组合,并最后筛选出8组共毒系数高于120的配比组合,高效氯氟氰菊酯与噻虫嗪的混配比为11∶2、11∶20时,共毒系数依次为161.13、197.11;联苯菊酯与硫双威的混配比为1∶2、5∶4、5∶1、25∶2时,其共毒系数依次为216.01、200.98、163.15、212.11;联苯菊酯与噻虫胺的混配比为1∶5、5∶1时,共毒系数依次为338.13、122.72,其中增效作用最明显的是混配比1∶5的联苯菊酯与噻虫胺组合。In order to test the toxicity of different combined insecticides on the Pleonomus canaliculatus,the immersion method was used to determine the toxicity of five single and various combined insecticides on the P.canaliculatus.By using the co-toxicity factor method and the co-toxicity coefficient method,a total of 11 groups of combinations with a co-toxicity factor higher than 20 were selected,and among the 11 groups of combinations,another screening was conducted.Finally,8 groups of combinations with a co-toxicity coefficient higher than 120 were selected.The co-toxicity coefficients lambda-cypermethrin and thiamethoxam with the ratio of 11∶2 and 11∶20 were 161.13 and 197.11,respectively.The co-toxicity coefficients of mixture ratio of bifenthrin and thiodicarb with the ratio of 1∶2,5∶4,5∶1 and 25∶2 were 216.01,200.98,163.15 and 212.11,respectively.The co-toxicity coefficient of bifenthrin and clothianidin with ratio of 1∶5 and 5∶1 were 338.13,122.72.The most obvious synergistic effect was the combination of bifenthrin and clothianidin with ratio of 1∶5.
