(E)-10-dodecen-1-yl acetate

The mechanism works by releasing the pheromone into the orchard environment, which masks the natural scent trails left by females, preventing males from successfully locating mates.

By disrupting the reproduction cycle, the population density of the next generation is significantly reduced without the use of broad-spectrum chemical insecticides.

This compound acts as a species-specific attractant, making it highly targeted and harmless to beneficial predatory insects, bees, and other non-target species.

The controlled release of the substance ensures a stable concentration of pheromone throughout the flight period of the target moths, maintaining effectiveness under various weather conditions.

This pheromone is aimed at controlling various species within the Tortricidae family, which are notorious pests of pomaceous and stone fruit crops.

It is widely used in apple, pear, and plum orchards, as well as in vineyard management to protect fruit from internal damage caused by larval feeding.

By minimizing larval populations, growers can significantly reduce the risk of secondary fungal diseases that infect fruit through insect-created wounds.

The active substance is part of a sophisticated approach to integrated pest management (IPM) designed to secure high-quality fruit yields.

• Codling moths (Cydia pomonella)
• Leafrollers
• Various Tortricid moth species

The application rate is defined by the number of dispensers or lures placed per hectare, which should be aligned with the density and canopy structure of the orchard.

Timing is critical: dispensers must be installed just before the onset of the first adult flight, which is monitored using standard trap records.

Consistent placement is essential, as the effectiveness of the mating disruption system depends on creating a uniform pheromone cloud throughout the orchard block.

Standard field longevity of dispensers ranges from 60 to 120 days, covering the main breeding seasons of multiple generations of the pest.

Growers should follow specific guidelines for placement height and pattern to optimize the saturation of the canopy space.

The technique is most effective on large, continuous orchards; small plots are prone to re-infestation from neighboring areas where mating disruption is not applied.

Proper storage is required to maintain product efficacy; dispensers should be kept in a cool, dark environment until the moment of field application.

Mating disruption is not a "quick fix" for high-pressure situations and should be used in conjunction with monitoring to assess if supplemental controls are required.

Personnel handling the dispensers must be cautious to avoid cross-contamination of clothing, which could render the pheromone system less effective.

Regular maintenance and monitoring of the field situation are necessary to confirm that the disruptant levels remain sufficient to prevent mating.
