Starch gel electrophoresis was used to resolve gene frequencies among populations of screwworm, Cochliomyia hominivorax (Coquerel). The loci examined coded for alpha-glycerophosphate dehydrogenase, octanol dehydrogenase, and phosphoglucomutase. Flies

Native screwworms, Cochliomyia hominivorax, in Chiapas, southwestern Mexico, had polymorphic chromosome variation characteristic of a single interbreeding population rather than of highly reproductively isolated gamodemes. Most of the variation found

The pattern of inheritance of resistance to methyl parathion in larvae of Heliothis virescens (F.) was studied by cross mating strains that were susceptible (S) or resistant (R) to topical applications. Homozygous, or apparently homozygous, S and R c

The longevity and mating behavior of 6 Texas and Mexico strains of screwworms, Cochliomyia hominivorax (Coquerel), were evaluated in the laboratory. None showed any unacceptable degree of laboratory adaptation at the time of testing. The mating behav

During 1978 in the Pacific coastal area of Chiapas, Mexico, populations of the primary screwworm, Cochliomyia hominivorax , reached seasonal highs in July and November-December and a seasonal low in April. Secondary screwworm, Cochliomyia macellaria

Two factory production strains of the screwworm, Cochliomyia hominivorax (Coquerel), were subjected to directional selection for increasing or decreasing pupal weight at 4 days. After seven or eight cycles of mass selection, average pupal weight incr

Karyotypes of 23 lines of screwworm, Cochliomyia hominivorax (Coquerel), flies originating as isofemale lines collected in the Mexican states of Colima, Michoacan, Oaxaca, Chiapas, Quintana Roo, and one line from the island of Jamaica were investigat

Visual sensitivity of flies of 4 colonized strains of screwworms was compared by use of an electroretinogram (ERG) technique. Flies of newly colonized strains were more visually sensitive than those from strains that had been colonized for long perio

Fluorescein sodium, a water soluble dye detectable under UV light, proved to be an excellent material for marking adult Cochliomyia hominivorax (Coquerel). The dye was detected by squashing adult screwworms on white filter paper and then viewing the
