| 摘 要： | 采用点滴法测定高效氯氰菊酯与辛硫磷混配对菜青虫幼虫的增效作用。结果表明:高效氯氰菊酯和辛硫磷以1∶15.7、1∶11.5和1∶6.1的比例混配共毒系数(CTC)分别为79.4、84.1和109.9,无增效作用。而高效氯氰菊酯和辛硫磷以1∶9、1∶7.3混配其共毒系数分别为174.3和129.0,表现出明显的增效作用。

| Abstract: | With the topical application method,the synergistic effect of beta cypermethrin mixed with phoxim to Pieris rapae was determined.The results indicated that beta cypermethrin combined with phoxim in 1:15.7,1:11.5,1:6.1 showed no synergism.The co-toxicity coefficients(CTC) were 79.4,84.1 and 109.9,respectively.Whereas the combinations in 1:9 and 1:7.3 showed significant synergistic effect to the pest,and CTCs were 174.3 and 129.0. |
