Experiments were conducted on the chemical control of a Held population of Tetranychus telarius (L.) on cotton, suspected of being resistant to organophosphorous miticides. Varying degrees of resistance by this spider mite were exhibited to demeton, ethion, carbophenothion, Bidrin ® (3 - hydroxy -N, N - dimethyl-cis-croton-amide dimethyl phosphate), and phorate. Other types of miticides such as Aramite® (2 (p-tert-butylphenoxy) isopropyl-2- chloroethyl suIrite) , chlorobenzilate, and Kelthane®(1,1- bis (p-chlorophenyl) -2,2,2-trichloroethanol) were found to have retained their effectiveness against this species. However, these materials were not so effective as the organophosphorous miticides were prior to the development of a resistant strain. Furthermore, field surveys revealed that difficulties in controlling either resistant or susceptible mites were induced largely by the failure to utilize cultural and natural controls On the basis of field observations, control of T. atlanticus McGregor with organophosphorous acaricides was not so good as that obtained in previous years.
