Abstract Drosophila yakuba is widespread in Africa. Here we compare the cuticular hydrocarbon CHC profiles and mating behavior of mainland Kounden, Cameroon and island Mayotte, Sao-Tome, Bioko populations. The strains each had different CHC profiles: Bioko and Kounden were the most similar, while Mayotte and Sao-Tome contained significant amounts of 7-heptacosene. The CHC profile of the Sao-Tome population differed the most, with half the 7-tricosene of the other populations and more 7-heptacosene and 7-nonacosene. We also studied the characteristics of the mating behavior of the four strains: copulation duration was similar but latency times were higher in Mayotte and Sao-Tome populations. We found partial reproductive isolation between populations, especially in male-choice experiments with Sao-Tome females. View Full-Text
