Isozyme Variation in Simulium (Edwardsellum) Damnosum S.L. (Diptera: simuliidae) from Kenya
Abstract
Isozyme variation of the Simulium damnosum sibling species complex was studied by cellulose acetate electrophoresis (CAE) from four Kenyan river systems. Two enzymes, PGM and HK, were diagnostic adn differentiated the larvae collected in Western and Nyanza provinces from the larvae collected at Mt. Kenya. Allele frequency differences of the enzyme PGI allowed about 75% separation of the geographically distinct populations. In recent years, isoenzyme electrophoresis has been extensively used in the discrimination and identification of medically important insect sibling species including Simuliidae. Raybould and White (1979) indicated that there are four members of the Simulium damnosum sibling species complex in Kenya. These four members have been classified by Dunbar (1976) into two major groups; the Sanje group and the Kibwezi group. The Sanje group, which is found only in eastern Africa, is a group of eight forms and a ninth form which is a hybrid of Sebwe and Nyamagasani forms. Reprints.
