Long-chain (Z)-9-alkenes are "psychedelics" to houseflies with regard to visually stimulated sex attraction and aggregation.
Three different tests on houseflies (Musca domestica L.) revealed that both pheromone-free pseudoflies and male partner flies exhibit in the presence of mixtures of long-chain (Z)-9-alkenes or pure (Z)-9-tricosene enhanced releasing effects for two optical cues, which stimulate male houseflies to mating strikes and houseflies of both sexes to aggregation.
