摘要
参照FAO推荐的浸渍法,研究了吡虫啉与联苯菊酯的5种配比对麦长管蚜的防治效果。结果表明,吡虫啉和联苯菊酯混配后,表现增效作用的配比为1∶1,2∶1,共毒系数(CTC)分别为273.22,126.17;表现相加作用的配比为1∶2,5∶1,共毒系数(CTC)为95.28,104.65;表现拮抗作用的配比为1∶5,共毒系数(CTC)为60.46。5种配比中以1∶1的配比增效作用最强。
Five kinds ratio of imidacloprid and bifenthrin are reaseached on Macrosiphum avenae（Fabricius）for synergistic effect refered to FAO recommended immersion method. The result shows that mixed ratio of synergistic effect are 1 ∶1,2 ∶1,co-toxicity coefficient（CTC）are 273.22,126.17,additive effect are 1∶2,5∶1,CTC are 95.28,104.65;antagonism effect is 1∶5,CTC is 60.46. The better ratio of synergistic effect was 1∶1,which can provide the reasonable mixed basis for imidacloprid and bifenthrin.
