Abstract
Natural populations of Glossina morsitans submorsitans Newstead, G. palpalis gambiensis Vanderplank and G. tachinoides Westwood occurring within 150 km of Bobo-Dioulasso, Upper Volta were examined using polyacrylamide gel electrophoresis. No variation was found in the banding pattern for arginine phosphokinase (ED 2.7.3.3). G. p. gambiensis and G. tachinoides had 3 alleles for each of the thoracic enzymes octanol dehydrogenase (EC 1.1.1.73), malic dehydrogenase (EC 1.1.1.37) and .alpha.-glycerophosphate dehydrogenase (EC 1.1.1.8) and for midgut alkaline phosphatase (EC 3.1.3.1). The same situation was found with G. m. submoristans except that only 2 alleles for .alpha.-glycerophosphate dehydrogenase and 1 for alkaline phosphatase were found. In each species, and for each of the enzymes, 1 allele was present at a frequency .gtoreq. 95%. There was little or no variation between populations. Two laboratory colonies of G. p. gambiensis had less genetic variation than wild populations.
