摘　　要：对西华田间棉铃虫种群，Ｐｂｏ能显著地增加氰戊菊酯、高效氯氰菊酯、灭多威的毒力，大幅度地降低其致死中量，ＴＰＰ对两种拟除虫菊酯杀虫剂也能表现一定的增效作用；对甲基对硫磷、甲胺磷，无论是Ｐｂｏ还是ＴＰＰ其增效作用均十分有限。增效剂对杀虫剂的增效效果与棉铃虫对该杀虫剂的抗性水平及其主导抗性机制密切相关。Pbo significantly synergizes to fenvalerate,α-cypermethrin and methomyl against Xihua field resistant strain of Heliothis armigera,TPP can somewhat synergize to pyrethroids also. Both of Pbo and TPP have little synergistic action to parathion-methyl and methamidophos.The synergistic action of synergists is tightly connected with the resistant level and main mechanism of Heliothis armigera to insecticides.
