Abstract
The house fly, Musca domestica L., is a vector for more than
100 human and animal diseases and has the ability to develope
resistance to different insecticides. This study evaluated toxicity of
Cypermethrin, Imidacloprid and Spinosad, in addition to, their mixtures
under laboratory conditions against larvae and adults of M. domestica
for laboratory strain. The LC50s of the three tested insecticides were
579.30, 415.46 and 16.32ppm, respectively, against larvae 48h post
treatment. The toxic effect of these insecticides against M. domestica
adults was assessed 24h post treatment. The LC50s of Cypermethrin,
Imidacloprid and Spinosad were 208.75, 238.3 and 86.05 ppm,
respectively, against the laboratory strain. This study also showed
efficacy of the binary mixtures of these insecticides, where the mixture
of Cypermethrin+Imidacloprid and Cypermethrin+Spinosad showed
potentiation at ratios 1:1, 1:2 and 2:1. On other hand, the mixture of
Imidaclporid+Spinosad showed an additive effect at all mixing ratios.
