| Abstract: | "(Z)-11-Octadecenyl acetate (Z11-18ratioAc) and (Z)-11-eicosenyl acetate (Z11-20ratioAc) were identified as the aggregation pheromones ofDrosophila ananassae, andZ11-20ratioAc was identified as the aggregation pheromone ofDrosophila bipectinata. Z11-18ratioAc andZ11-20ratioAc were not attractive alone; however, in combination with fermenting food odors, the acetates attracted flies of both sexes in a wind-tunnel olfactometer. The pheromones were present in the ejaculatory bulb of sexually mature male flies and transferred to the female during mating. MaleD. bipectinata released little if anyZ11-20ratioAc to the food; however, recently mated females releasedZ11-20ratioAc to the surrounding surfaces in just a few hours after mating.D. ananassae males, on the other hand, appeared to release moreZ11-18ratioAc andZ11-20ratioAc to the surroundings than mated females. AlthoughD. bipectinata males had noZ11-18ratioAc, flies were as attracted toZ11-18ratioAc as to an equal quantity ofZ11-20ratioAc.D. ananassae were attracted toZ11-18ratioAc but not toZ11-16ratioAc orZ11-20ratioAc. However,Z11-20ratioAc in combination withZ11-18ratioAc was significantly more attractive thanZ11-18ratioAc alone" |
