Resistance against dicofol was investigated in the carmine spider mite, Tetranychus cinnabarinus. Higher resistance levels were detected by leaf residual bioassays than by topical bioassays, both done using a Potter spray tower, in almost all populations of T cinnabarinus examined from Antalya, Turkey. For instance, the resistance level at LC95 was 17.5-fold in topical bioassays but 58.9-fold in leaf residual bioassays for the population collected from greenhouses in the Topcular district. There were differences of resistance levels at LC95, ranging between 2.6- and 23.9-fold using topical bioassays and between 5.0- and 58.9-fold in residual bioassays, in populations collected from greenhouses from various districts. Populations from cotton showed lower resistance levels against dicofol than populations from greenhouses.
