Extract
The susceptibility of Musca domestica nebulo F. and M. d. vicina Macq. to topical applications of p,p' DDT, technical dieldrin and γ BHC was determined in Aligarh, India, and the effects of using acetone, Eisella oil or ethanol as solvents were also investigated. Of the three insecticides examined, BHC was found to be the most toxic to both forms of house-fly, and DDT the least toxic, though the latter would be effective for control purposes at concentrations exceeding 1 per cent. Solutions of the insecticides in ethanol were more toxic than solutions at the same concentration in Eisella oil, and the latter were slightly more toxic than solutions in acetone. The two forms of house-fly were about equally susceptible to DDT, but M. d. vicina was somewhat more susceptible to dieldrin and BHC than M. d. nebulo. Males of both forms were more susceptible than females to all three insecticides.
