Infobox references

(Z)-9-Tricosene (muscalure) is an insect pheromone used as a pesticide.

Biological functions

(Z)-9-Tricosene is a sex pheromone produced by female house flies (Musca domestica) to attract males. In bees, it is one of the communication pheromones released during the waggle dance.^[3]

Uses

As a pesticide, (Z)-9-tricosene is used in fly paper and other traps to lure male flies, trap them, and prevent them from reproducing.^[4]

Biosynthesis

(Z)-9-Tricosene is biosynthesized in house flies from nervonic acid.^[5] The acid is converted into the acyl-CoA derivative and then reduced to the aldehyde (Z)-15-tetracosenal. Through a decarboxylation reaction, the aldehyde is converted to (Z)-9-tricosene. The process is mediated by a cytochrome P450 enzyme and requires oxygen (O₂) and nicotinamide adenine dinucleotide phosphate (NADPH).

Safety

Products containing (Z)-9-tricosene are considered safe for humans, wildlife, and the environment.^[4]
