Abstract

The level of insecticide resistance of the Mediterranean fruit fly, Ceratitis capitata (Wiedemann) and the peach fruit fly, Bactrocera zonata (Saunders) (Diptera: Tephritidae) to seven insecticides was assessed by bait bioassay technique under laboratory conditions. The tested insecticides were chlorpyrifos-methyl (organophosphates), α-cypermethrin, lambda-cyhalothrin, deltamethrin (pyrethorids), emamectin benzoate, spinosad (microbial) and imidacloprid (neonicotinoids). The results showed that emamectin benzoate and deltamerthin insecticides had the highest toxicity for the laboratory strain of C. capitata and B. zonzta, respectively. While Chlorpyrifos -methyl was the least toxic to both species. C. capitata was more susceptible to tested insecticides than B. zonata. The females of C. capitata as well as B. zonata of the laboratory and field population were less sensitive than the males. The toxicity of the tested insecticides was increased with the increase of exposure time. Moreover, each of chlorpyrifos, lambda-cyhalothrin, deltamethrin and α-cypermethrin showed moderate to high levels of resistance. No to moderate resistance were found for the spinosad, imidacloprid and emamectin benzoate pesticides.
