CYTOGENETIC AND ISOZYMIC COMPARISONS OF 2 LABORATORY LINES OF GLOSSINA-PALPALIS-GAMBIENSIS

The genetics of two laboratory colonies of Glossina palpalis gambiensi s were characterized by C-banding and isoenzyme studies. The colonies, derived from flies collected in the same locality, had different hist ories in the laboratory and different susceptibilities to trypanosome infection. Although the two lines were also found to differ in the fre quencies of chromosome and isozyme variants, the variation was not eno ugh to put their specific status in doubt; it was probably the result of genetic drift since the foundation of the colonies.
