Abstract: 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.
