Abstract

The response of a susceptible strain of the adult house fly Musca domestica L. to eight insecticides was determined. Two organophosphorus (OP) insecticides, fenthion and propetamphos, five pyrethroid (PY) insecticides: cyfluthrin, cypermethrin, permethrin (cis: trans, 25:75), permethrin (cis:trans, 40:60), and d- tetramethrin, and one carbamate (C) insecticide, propoxur, were under investigation. The field house fly population was slightly tolerant to propetamphos followed by fenthion of the OP insecticides, with Resistance Factors (RFs) of 3.55x and 7.61x, respectively. For pyrethroid insecticides, the fly showed various degrees of tolerance to cypermethrin, permethrin 25:75 and permethrin 40:60, with RFs of 4.19x, 6.14x and 8.18x, respectively. On the other hand, the house fly was slightly resistant to cyfluthrin and d-tetramethrin with RFs of 10.84xand 28.12x, respectively. For the carbamate insecticide propoxur, the RF was 15.24 indicating that the house fly population was slightly resistant and rather homogenous in its response to this insecticide. The population of the house fly was found to have various degrees of homogeneity with tolerance or resistance to the tested insecticides. The field population is still least tolerant to propetamphos and cypermethrin. However, all insecticides with RFs less than 10 can still be used for the control of the house fly.
