Abstract

The performance of native and laboratory-bred Glossina morsitans morsitans Westw. was observed in Kariba, Rhodesia, the original natural habitat of the colonised Langford strain. After two years in captivity, the Langford strain was similar to the native strain in survival, dispersal, and rate of recovery in the field. No differences were detected in laboratory studies of the mating behaviour of the two strains. Native-strain males sterilised in the pupal stage with tepa were similar to untreated males in dispersal, survival, and rate of recovery. Also, both the released laboratory-bred flies and the released native strain flies compared favourably with the native population.
