Abstract
The present study indicated that the repeated exposure of the
laboratory strain of the house fly, Musca domestica (Linnaeus) to
Cypermethrin, Imidacloprid and Spinosad lead to developing resistance
against these insecticides. The resistance level of the selected strains
reached after 30th generation to 24.8, 15.53 and 9.56 folds for
Cypermethrin, Imidacloprid and Spinosad compared with the laboratory
strain.
This study also showed the breakdown of resistance using
insecticide binary mixtures, where the mixture of Cypermethrin+
Imidacloprid exhibited potentiation at the ratio of 1:1 and 1:2 against all
the resistant strains. Also, the combination of Cypermethrin with
Spinosad gave potentiation at the ratios of 1:1, 1:2 and 2:1 against
Imidacloprid and Spinosad resistant strains.
