摘　　要：[目的]评价胡椒基丁醚对四氯虫酰胺和高效氯氰菊酯防治菜青虫的增效作用。[方法]田间试验采用喷雾法。[结果]药后1 d胡椒基丁醚对四氯虫酰胺和高效氯氰菊酯都有显著的增效作用,在药后3、7、14 d无增效作用。与胡椒基丁醚预处理后再施药相比,胡椒基丁醚与药剂桶混施药的防效差异不显著。[结论]胡椒基丁醚对四氯虫酰胺和高效氯氰菊酯防治菜青虫在短时间内具有显著的增效作用,且增效作用与胡椒基丁醚的使用方式无关。[Aims] This study aims to evaluate the synergistic effect of piperonyl butoxide to tetrachlorantraniliprole and beta-cypermethrin against Pieris rapae. [Methods] The field efficacy trials were conducted by spraying. [Results] On the1 st day after treatment, piperonyl butoxide exhibited a significant synergistic effect on both tetrachlorantraniliprole and beta-cypermethrin against P. rapae, however, no synergistic effect was found on the 3 th, 7 th, 14 th day after treatment.Moreover, there was no significant difference in efficacy against P. rapae between the treatment by insecticide after pretreated with PBO and the treatment with the tank mixture of insecticide and PBO. [Conclusions] Piperonyl butoxide has a significant synergistic effect on tetrachlorantraniliprole and beta-cypermethrin against P. rapae for a short period of time, furthermore, the synergistic effect has nothing to do with the application way of piperonyl butoxide.
