Various rates of lindane and dimethoate were used in different localities against cabbage maggots in cabbages and tests were done on hatching larvae of Delia floralis Fall. to determine the possible resistance of 3 field strains to these insecticides. Considerable differences were noted in the efficacy of both insecticides in various localities and significant differences were found in the susceptibility of different strains to both insecticides. The LC 50-values compared with those of the most susceptible strain were, however, less than 3-fold. The reasons for the poor efficacy of the insecticides are discussed.
