Levels of the pheromone 7,11-heptacosadiene in the sibling species Drosophila simulans and Drosophila sechellia

This dataset provides measurements of the cuticular pheromone, 7,11-heptacosadiene of individual female vinegar flies. The purpose of the dataset is to compare the levels between two sibling species, Drosophila simulans and Drosophila sechellia. Single female virgins were isolated from males at eclosion, aged five days, and then washed in hexane to extract cuticular hydrocarbons. The extracts were analyzed by gas chromatography relative to an internal standard.
