(Z)-9-Tricosene 27519-02-4 86%TC,0.05%WDG



Introduction: (Z)-9-Tricosene, known as muscalure, is an insect pheromone found in dipteran flies such as the housefly. Females produce it to attract males to mate. It is used as a pesticide, luring males to traps to prevent them from reproducing.

(Z)-9-tricosene or (cis-9-tricosene), is a twenty-three carbon straight chain compound with a double bond between the ninth and tenth carbon atom. It is in the general hydrocarbon family referred to as alkenes. This family of compounds is relatively more reactive than saturated hydrocarbons (alkanes) in laboratory reactions. However, in the environment alkenes would be expected to persist. The solubility of straight chain alkenes generally tends to decrease as the number of carbons increases. The major routes of dissipation in the environment would be expected to be volatilization and microbial mediated degradation.

Usage: (Z)-9-Tricosene was sex hormone derived from the female flies by Carlson et al., and developed as an insect attractant by Zoecon Industries Ltd.(Sandoz AG). Pheromones are volatile chemicals produced by a given species to communicate with other individuals of the same species. The purpose is to change the behavior of the individuals who smell or otherwise sense the pheromone. For example, many kinds of female insects, including flies, produce pheromones that attract males of the same species. Animals also use pheromones to mark territory (dogs, bears), or to warn other individuals of danger. Pheromones are effective in tiny amounts, and act only on one species or a few closely related species.

Application: Although pure (Z)-9-tricosene is a liquid, the final form of the active ingredient is usually a solid that has been impregnated with the pheromone. The impregnated material is then attached to a bait station, trap, strip, or other item. The pheromone is slowly released to the air over a period of weeks.
