Isozymic comparison of five laboratory lines of tsetse flies belonging to the two subspecies of Glossina palpalis (Diptera: Glossinidae).

ABSTRACT

Three laboratory colonies of Glossina palpalis palpalis and two of G. p. gambiensis have been characterized by means of 14 polymorphic enzyme loci. The presence/absence of some alleles for three enzymes (octanol dehydrogenase, phosphoglucomutase and aldehyde oxidase) distinguished the two subspecies. Other differences in allozymes could not be used to discriminate between subspecies but could be used to distinguish populations within each of the subspecies. The genetic differences between populations of a given subspecies are briefly discussed.
