Abstract: The use of pesticide would adversely affect the predatory mites, and reduce their control of pest mites. To filter out the pesticides safe to predatory mites and guide productive practices, this study determined the lethal effect of six kinds of commonly used acaricides and three kinds of fungicides on Amblyseius pseudolongispinosus by indoor leaves spray method. The results indicated that the correction mortality rates of female adult Amblyseius pseudolongispinosus were low, which were 0, 5% and 7.7% respectively, by 72% curzate wettable powder, 70% topsin methyl wettable powder, and 50% carbendazol wettable powder. There was no significant difference between them. The correction mortality rates of female adult Amblyseius pseudolongispinosus were higher, which were 79.5% and 53.9% respectively, by 1.8% chongmanke emulsifiable solution and 15% pyridaben emulsifiable solution. The correction mortality rates of female adult Amblyseius pseudolongispinosus were lower, which were 15.4%、17.9%、20.5% and 28.2% respectively, by 73% propargite emulsifiable solution, 20% azacyclotin suspending agent, 5% hexythiazox emulsifiable solution and 8% Zhongbaoshaman emulsifiable solution. Compared with 1.8% Chongmanke emulsifiable solution and 15% pyridaben emulsifiable solution, the correction mortality rates of female adult Amblyseius pseudolongispinosus were statistically significant.
