Abstract

Targeting an insect pest having a carboxylic acid compound as a pheromone substance, provided is a sustained release pheromone preparation enabling a high amount of pheromone to be released during the control period. More specifically, provided is a sustained release pheromone preparation, comprising: a carboxylic acid compound to be released, and an ethylene-vinyl acetate copolymer membrane through which the carboxylic acid compound can permeate, wherein the preparation is targeted for an insect pest having the carboxylic acid compound as a pheromone substance.

First claim

The invention claimed is:

1. A sustained release pheromone preparation, comprising:
a container;
a carboxylic acid compound in the container to be sustainedly released to the outside of the container, said carboxylic acid compound is selected from the group consisting of 3,5-dimethyl dodecanoic acid, Z-5-undecenoic acid, and E-5-undecenoic acid; and
an ethylene-vinyl acetate copolymer membrane which comprises at least part of the container, through which the carboxylic acid compound can permeate,
wherein the preparation is targeted for an insect pest having said carboxylic acid compound as a pheromone substance.

2. The sustained release pheromone preparation according to claim 1 , wherein the ethylene-vinyl acetate copolymer contains 4 to 20% by weight of vinyl acetate repeating units.

3. The sustained release pheromone preparation according to claim 1 , wherein the preparation is in form of a capsule, an ampoule or a bottle.

4. The sustained release pheromone preparation according to claim 2 , wherein the preparation is in form of a capsule, an ampoule or a bottle.
