Permeabilization of Cochliomyia hominivorax (Diptera: Calliphoridae) embryos.

Comparison of gelled and meat diets for rearing screwworm, Cochliomyia hominivorax (Diptera: Calliphoridae), larvae.

Amplified fragment length polymorphism used for inter- and intraspecific differentiation of screwworms (Diptera: Calliphoridae).

Morphologically, early immature stages of the economically important pest called screwworms, Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae), and non-pest secondary screwworms, Cochliomyia macellaria (Fabricius) (Diptera: Calliphoridae), are nearly indistinguishable. Correct identification is crucial to the ongoing eradication and exclusion program protecting the United States, Mexi...

Cryopreservation of Embryos of the New World Screwworm <i>Cochliomyia hominivorax</i> (Diptera: Calliphoridae)

A method for cryopreserving embryos of the screwworm, Cochliomyia hominivorax (Coquerel), was developed for the long-term storage of strains used in research projects and for colonies maintained as back-up to production strains that are mass-reared for sterile insect release programs. This protocol, when combined with a previous procedure that was designed to render screwworm embryos permeable ...

Myiasis by screw worm Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) in a wild maned wolf Chrysocyon brachyurus (Mammalia: Canidae), in Brasília, Brazil.

In April 2009, a wild maned wolf, Chrysocyon brachyurus, was captured in an area of cerrado in Brasília, DF, Brazil, with screw worm maggots in external wounds. Fifty larvae were bred in the laboratory and eight adults of Cochliomyia hominivorax (Coquerel) emerged 10 days after pupation. This is the first report of a myiasis by C. hominivorax in a free-living maned wolf in Brazil.

Postlarval fitness of transgenic strains of Cochliomyia hominivorax (Diptera: Calliphoridae).

Eight transgenic strains of Cochliomyia hominivorax (Coquerel) (Diptera: Calliphoridae) were compared with the wild-type parental laboratory strain (P95) in colony. Measurements of average weight of pupae, percentage of adults emerging from pupae, ratio of males to total emerged adults, and mating competitiveness were analyzed. The parental strain colony was subcultured and exposed to handling ...
