(4Z,9Z)-7,9-Dodecadien-1-ol

This substance is a synthetic sex pheromone, specifically designed to mimic the chemical communication signals of certain insect species.

The primary mode of action is mating disruption, a technique that saturates the orchard environment with synthetic pheromone molecules.

By creating a high-concentration pheromone fog, male insects are unable to locate females, effectively shutting down the mating cycle.

This disruption prevents fertilization, ensuring that no viable eggs are laid, which leads to a collapse of the pest population over time.

This method acts as a biological control tool that reduces the necessity for broad-spectrum insecticide sprays in commercial orchards.

The compound is primarily targeted at controlling the codling moth (Cydia pomonella), a major pest of pome fruits worldwide.

It interferes with the adult moths' ability to find mates, thereby protecting apples, pears, and walnuts from larval infestation.

The pheromone profile is specific to certain moth species, ensuring that beneficial insects and pollinators remain unaffected by the treatment.

It is an essential component of Integrated Pest Management (IPM) programs aimed at reducing fruit damage caused by lepidopteran larvae.

Targeting the reproductive stage provides a highly selective approach to controlling orchard pests without inducing chemical resistance.

The application rate depends on the pest pressure level and the specific layout of the orchard canopy to ensure uniform coverage.

Dispensers containing the active ingredient should be deployed in the upper canopy before the first moth flight begins.

Monitoring traps are necessary to determine the exact timing of deployment based on the first emergence of adults in the current season.

The pheromone release duration is engineered to last for the entire seasonal activity period of the target moth generation.

• Typical field application: 400 to 600 dispensers per hectare.
• Uniform distribution is critical to prevent gaps in the pheromone plume.

Mating disruption is most successful in larger, contiguous orchard blocks to avoid the intrusion of mated females from surrounding areas.

Active ingredients are sensitive to environmental conditions, so storage should occur in a cool, dark environment to maintain potency.

The pheromone does not kill existing larvae; therefore, high initial populations may require supplementary chemical interventions.

It is not a curative treatment for current fruit damage and acts strictly as a preventative long-term management strategy.

Users should handle dispensers with protective gloves to avoid personal exposure and ensure the integrity of the release mechanism.
