Inheritance of Aldrin Resistance in the Indian House-fly, Musca domestica nebulo F

Abstract

The inheritance of aldrin resistance in the Indian house-fly, Musca domestica nebulo F., was studied by making reciprocal crosses between individual as well as groups of flies of an aldrin-resistant and a non-resistant strain of the subspecies at 28±1°C. The offspring of all the families thus formed were tested by the topical application of constant-volume drops of various concentrations of aldrin solution in oil to the dorsum of thorax of groups of flies. Mortality counts were made 24 hours after treatment. The results obtained indicated a multifactorial heredity for aldrin resistance in M. d. nebulo. The phenomenon was found not to be sex linked.
