Abstract
A preliminary study was carried to elucidate resistance to acarcides in red mites which is considered as the most important problem facing their control. Experiments were carried to test number of acaricides on a resistant strain of Tetranychus urticae Koch to Dimethoate. The following acaricides Abamectin, Lufenuron, Diafenthiuron, Bromopropylate, Biphenthrin and Azocyclotin, gave good results, where the mortality exceeded 80% for each, compared with a sensitive strain to Dimethoate. These results suggest the possible use of these compounds in the control programs of mites without fear from occurrence of resistant strains. However, the acaricides Carbosulfan, Buprofeezin and Spenosad gave unsatisfactory results.
