Abstract: Fruit flies are among the most important group of pests causing economical losses by damaging fruits worldwide. They have countless economic significance in Pakistan due to their substantial losses. In current research entomopathogenic nematode (EPNs) and bacterial based spinosad was checked against melon fruit fly, Bactrocera cucurbitae under laboratory conditions. Different concentrations of nematodes and spinosad sole and in combination was applied on B. cucurbitae. Bacterial based spinosad was applied by dip method whereas nematodes were applied on the soil surface. Mortality data was checked against larvae, pupae and adults. Single and combine effect of EPNs and spinosad was also checked on fruit fly developmental time. Results showed that spinosad bacterial based concentrations cause maximum mortality against melon fruit fly as compared to nematode. While combine effect of spinosad and nematode mortality was increased gradually with increasing concentrations as compared to alone treatment. Our results conclude that nematode and bacterial based spinosad have a sound base for the effective management of fruit flies species. These results could be helpful for application of nematode and spinosad in Insect Pest Managements Programs.

Keywords: Mortality, nematodes, spinosad, larvae, pupae, adult, development.
