Cochliomyia is a genus in the family Calliphoridae, known as blowflies, in the order Diptera. Female screwworm flies, Cochliomyia hominivorax (Coquerel), visit wounds of warm-blooded animals to feed and oviposit, with feeding visits occurring twice as of We use cookies to enhance your experience on our website.By continuing to use our website, you are agreeing to our use of cookies. Other genera of myiasis-causing flies (including Cochliomyia, Cuterebra, and Wohlfahrtia) have a more direct life cycle, where the adult flies lay their eggs directly in, or in the vicinity of, wounds on the host . Such pigmentation is unique to this species among those encountered in wound myiasis and is a major character for identification keys. The use of ivermectin to kill third instar larvae in the patient did not interfere in its life cycle; however, the lower winter temperatures increased the pupal stage, which normally lasts an average of eight days (Neves et al.

As they are serious pests, considerable effort has been made to develop genomic resources and functional tools aiming to improve their management and control. Snail and slugs are the intermediate hosts, but the cat is probably infected by eating transport hosts, e.g., rodents, birds, amphibia, and reptiles.
