Five inorganic salts were evaluated to detect their effect on the cucurbit fly, Dacus ciliatus (Leow) (Diptera: Tephritidae) by applying the pupal dipping method in a serial of descending concentrations. The result showed that all tested inorganic salts adversely affected the adult emergence and reduced the egg laying capacity and egg hatchability. These salts could be arranged according to their toxicological effect to D. ciliatus as following: KBr2 NaoH ZnSo4 NaHpo4 CUCI2 ,and according to their sterility effect as following: Cucl2= KBr2=NaoH =ZnSo4 NaHpo4. This approach helps in mass production techniques of this pest and utilization the spreading sterilized pupae as a tool minimizing the population size.
