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. | ||||
