Abstract
The present study was conducted to evaluate the toxicity of different insecticides: imidacloprid, fipronil, cypermethrin and chlorpyrifos against the adult stage of fruit fly during 2019. B. zonata maggots were found vigorously feeding inside the cucurbit hosts (pumpkin, cucumber, bitter gourd, watermelon, round melon, bottle gourd) collected from different localities of district Peshawar, Pakistan. Susceptibilities of B. zonata to insecticides were evaluated using topical method. Mortality was checked after 3, 6, 8 and 24h of exposure. Cypermethrin was most effective to kill 50% of adult stage, respectively followed by imidacloprid. Imidacloprid most effectively killed 90% of adult population respectively after 24 hours. Toxicity of each insecticide increased with exposure for longer time and increased dose.
