Laboratory experiments were carried out to evaluate the activity of Colocynth (cucurbitaceae) leaf powder and leaf chloroform extract against the house fly (Musca domestica L.) larvae and pupae. Addition of Colocynth leaf powder to the food of House fly larvae caused dose –dependant reduction in larvae weight, faster development to pupae with subsequent reduction in number of emerged adults especially at high dose. Further dipping of house fly pupae in leaf chloroform extracts, caused significant delay and reduction in number of emerged adults .

    Generally, the result indicated the presence of antifeedant and growth regulatory agent in the examined members of the family cucurbitaceae. Further lines of research were outlined.
