摘　　要：朱砂叶螨(Tetranychuscinnabarinus)是一类植食性害螨,在我国危害严重,严重破坏我国农业生产,目前国内在该螨防治方面仍具有很大的发展空间.药剂混配不仅对害虫害螨起到了良好的防控效果,还可延缓害虫害螨对单一药剂抗性产生的速度,甚至阻止其抗性产生,在用药成本上还可减少药剂使用频率和使用量,提高经济效益.因此,本研究通过对联苯肼酯、阿维菌素、乙螨唑与植物源杀螨剂滨蒿内酯进行不同比例的复配以及对朱砂叶螨进行生物活性测定,探讨不同杀螨剂对朱砂叶螨的协同增效作用.结果发现,滨蒿内酯对联苯肼酯、阿维菌素、乙螨唑的杀螨活性均有明显的协同增效作用,最佳配比分别为1∶9,3∶7和9∶1,为害螨的防治以及药物混配效应的研究奠定一定的基础.Tetranychus cinnabarinus,a kind of phytophagous mite,which is seriously harmful in China and seriously destroys agricultural production in China.Previous studies have shown that the mixture of pesticides not only has a good effect on the prevention and control of pest mites,but also can delay the rate of resistance development of pest mites to a single pesticide,or even prevent the mites to develop the resistance.In terms of drug cost,it can also reduce the frequency and amount of chemical use,and improve economic benefits.Therefore,in this study,the synergistic effects of biphenyl hydrazine,avermectin,ethacarbazol mixed with botanical acaricidal agent scoparone in different proportions on control of cinnabar spider mite were determined by investigation of biological activity of cinnabar spider mite.The results showed that artemisia lactone had obvious synergistic effect on the acaricidal activities of biphenylhydrazine,avermectin and ethanazole,and the optimal ratio was 1∶9,3∶7 and 9∶1,respectively.This study laid a foundation for the study of prevention and control of harmful mites and the effect of mixed drug.
