Swarm of blow flies (true synanthropes), Chrysomyia megacephala Fabr. (Diptera:Calliphoridae), are found every where: in the houses, the poultry farms, garbage pile, manure, and any unsanitation areas. The laboratory mass rearing of these blow flies revealed their eggs hatched normally as found in nature. Various concentrations of the juvenile hormone analogue which is a growth regulating substance were tested at all stages of development (from egg to adult) by topical drop and dipping methods. The total mortality (three days) for each stage were recorded. It was found that this substance affected the gastro-intestinal tract and the reproductive system which resulted in the failure of mating, interference of oogenesis, and malformation of eggs in the ovariole sac such that much less eggs were laid. In addition, it affected the body size and the compound eyes. In treated adults it shortened their longevity, lowered the rates of mating and oviposition. It also inhibited the growth of ovaries and ovarioles. This growth regulating substance and its analogues may be acting as a source of mutagen or teratogen of embryo tissues.
