Insecticide Resistance: Effects of WARF Antiresistant on Toxicity of DDT to Adult Houseflies.
Addition of N, N-dibutyl-p-chlorobenzene sulphonamide (Antiresistant/DDT) in amounts equal to one fifth the dose of DDT increased the toxicity of DDT to the DDT-resistant portion of a housefly population. Full susceptibility was not regained. There was no increase in toxicity to the DDT-susceptible portion.
