Abstract
Examination of chromatograms of karyotyped larvae of Anopheles gambiae s.s. and Anopheles arabiensis has revealed that there are differences in the profile of their epicuticular hydrocarbons. A discriminant analysis of the quantitative hydrocarbon data has shown that the An. gambiae Mopti 2Rbc/bc karyotype from Mali could be separated from the Forest 2La/a karyotype from Liberia in >80% of cases. Similar analysis permitted > 80% separation of individuals of two karyotypes of Anopheles arabiensis: 2Rab/ + from Burkina Faso, and 2Rb/b from Madagascar.
