Two colonies of glossina pallidipes originating from the Shimba Hills and Nguruman, Kenya, were examined for their susceptibility to two strains of Trypanosoma congolense and for allele frequencies at eight polymorphic loci. These data were compared with data from earlier studies of these colonie...
Trypanosoma vivax is transmitted to domestic livestock by tsetse flies (Glossina spp.) after cyclical development in the vector (cyclical transmission) as well as directly (mechanical transmission) by other bloodsucking insects such as horse-flies and stable-flies (Hoare, 1947; Wells, 1972). Thus...
Druing translocations of black rhinoceros (Diceros bicornis Linnaeus) in Kenya, we studied the relationships between the rhinoceros and biting flies. In trapping experiments, rhinoceros waste products (urine or dung) were substituted for known attractants such as cow urine, 1-octen-3-ol or aceton...
Tsetse flies Glossina spp. (Diptera: Glossinidae) harbor three different symbiotic microorganisms one being an intracellular Rickettsia of the genus Wolbachia. This bacterium infects a wide range of arthropods, where it causes a variety of reproductive abnormalities, one of which is termed cytopl...
In a single generation of selection, two lines of Glossina morsitans centralis were established that differed significantly in susceptibility to Trypanosoma congolense clone IL 1180. Reciprocal crosses demonstrated that susceptibility was a maternally inherited trait. Differences between the line...
The susceptibility of G. longipennis, G. brevipalpis and G. morsitans centralis to various strains of Trypanosoma vivax, T. congolense and T. brucei brucei was investigated in the laboratory. Cattle and goats were infected with the trypanosomes and the tsetse fed from them during the first parasi...
