Abstract The effect of aqueous extract of Olea auvopea L. on inhibition of ovary growth in house fly Musca domestica L. as well as itُs effect on mid gut tissue structure, at concentrations, 0.5 , 1 , 2.5 and 5 % . Results show significant inhibition of ovary growth and itُs follicles at 1 , 2.5 and 5 % during 24 , 48 hours after emergence. After 72 hours of emergence, the concentrations 0.5 and 5 % were caused significant inhibition in ovary growth and its follicles also these concentrations led to reduction in ovary size and number of follicles as well as lyses with deformity in their shape and sheath. The histological pictures showed separation of circular and longitudinal muscles from basal membrane and undistinguished of epithelial cells and reduction in circular muscles thickness.
