摘　　要：用乙酰甲胺磷原粉等6种杀虫剂的两元混合物对水稻大螟幼虫的室内活性测定表明,乙酰甲胺磷与毒死蜱的有效成分按4∶1复配增效最明显;溴氰菊酯与毒死蜱、乙酰甲胺磷分别以有效成分1∶8、1∶1复配的增效作用最大;高效氯氰菊酯和溴氰菊酯有效成分按5∶1复配的增效作用明显。阿维菌素与毒死蜱的有效成分复配没有增效作用;阿维菌素与乙酰甲胺磷复配表现为拮抗作用。The synergism of six insecticide mixture against Sesamia inferens larvae was measured, and the best ratio was confirmed. The result showed that the mixture of acephate and chlorpyrifos had synergic action certainly. When the ratio was 4：1, the CTC was the highest. Mixture of deltamethrin with chlorpyrifos and acephate by 1：8, 1：1 gave the greatest synergies, respectively. Mixture of beta-cypermethrin and deltamethrin by 5：1 complex gave obvious synergism effect. Avermectin with chlorpyrifos was no synergism effect. Avermecitin and acephate complex perfor mance antagonistic effect.
