7,11heptacosadiene

The mating and social behaviors of insects are largely orchestrated by a suite of volatile cuticular hydrocarbon pheromones. 7(Z),11(Z)-Heptacosadiene is the predominant female-specific courtship pheromone of the fruit fly D. melanogaster. At amounts above 100 ng, 7(Z),11(Z)-heptacosadiene elicits wing vibrations in male D. melanogaster flies in a dose-dependent manner.
