. Gonotrophic and embryonic development of Wohlfahrtia magnifica were studied on pupae and adults reared in the laboratory. Gonotrophic development in screwworm begins 8 days after pupation in yellow eye pharate adults. The adult female emerges with its oocytes at stage 3 and requires only 2 days for complete oogenesis and 5 days for complete embryogenesis. Mating occurs 2–5 days after adult emergence, starting the embryonic development. Each female produces an average of 76.8 active larvae which can produce a traumatic lesion in their hosts. When food sources were regularly supplied, synchronization of gonotrophic stages can be observed. These stages together with the embryonic ones are described.
