Effects of caffeine on mating frequency and pre-copulation and copulation durations in Drosophila prosaltans.
Parameters of sexual behaviour were studied in Drosophila prosaltans treated with 2,500 micrograms/ml of caffeine per 1 ml of banana culture medium. The mating frequency and copulation duration were greater in control than in treated flies, while the pre-copulation duration was greater in treated flies than in controls. Statistical analysis showed that for the pre-copulation duration the difference was significant.
