Abstract: Carmine spider mite is one of the most important pest insects of cotton in Henan Province,Resistance of the mite to insecticides was studied during 1986-1987, Susceptibilities of thirteen strains of the mite collected from diff-erent cotton areas to two principal acaricides-dicofol and omethoate were determined by slide dip method. The result showed that the resistance had appeared almost all cotton counties sampled.The toxicities of 23 kinds of selective pesticides to the female adult of susceptible strain (Baiquan strain) and resistance strain(Xinxiang strain) were eveluated still by the slide dip method, The strain of Xinxiang had a high degree of resistance to organoph-osphor,especially parathion(466.8-fold at LCS。),but no resistances were found to methrin,PP32I,plictran,propargite,ect,
