AI Technical Summary

Technical Problem

Existing sustained-release formulations of aldehyde compounds with 14 to 18 carbon atoms and three or more carbon-carbon unsaturated bonds suffer from inconsistent release rates, leading to polymerization on the container surface and requiring frequent reinstallation, which increases labor and pheromone substance use.

Method used

A formulation comprising an aldehyde compound with 14 to 18 carbon atoms and three or more carbon-carbon unsaturated bonds, combined with an aliphatic acetate having 2 to 4 more carbon atoms, sealed in a container, ensures a constant release rate over the pest control period.

Benefits of technology

The formulation maintains a consistent release of the aldehyde compound for about 6 months, reducing the need for frequent reinstallation and minimizing pheromone substance use, thus lowering labor and costs.

Abstract

The present invention provides a sustained-release pheromone formulation containing a pheromone substance, such as a sex pheromone substance, which is an aldehyde compound having 14 to 18 total carbon atoms and three or more carbon-carbon unsaturated bonds, wherein the release rate of the aldehyde compound remains constant throughout the pest control period, and also provides a method for controlling pests using the formulation. [Solution] A sustained-release pheromone preparation is provided, comprising at least a mixture containing a pheromone substance which is an aldehyde compound having 14 to 18 total carbon atoms and having three or more carbon-carbon unsaturated bonds, such as a sex pheromone substance, and an aliphatic acetate having a total carbon atom number 2 to 4 more than the total carbon atoms of the sex pheromone substance, and a container containing the mixture. A method for controlling pests is also provided, comprising at least the step of placing the sustained-release pheromone preparation in a field and releasing the pheromone substance, such as a sex pheromone substance, from the sustained-release pheromone preparation.
