PROBLEM TO BE SOLVED: To provide a sustained-release preparation of sexual pheromones enabling them to be simultaneously released under control with a plurality of kinds of pests as targets and enabling them to be released so as to match with the breeding periods of the pests, and to provide a method of controlling the pests.SOLUTION: The sustained-release preparation for sexual pheromones contains at least two sexual pheromones each consisting of a 10-20C aliphatic derivative. This preparation comprises a 1st chamber of polymeric material containing part or the whole of the sexual pheromone with the minimum number of carbon atoms except the carbon atoms in the functional group among the aliphatic derivatives and a 2nd chamber of polymeric material containing the balance of the sexual pheromones. The method of controlling pests using this preparation is also provided.COPYRIGHT: (C)2005,JPO&NCIPI【課題】複数の害虫を対象として制御された同時放出を可能とし、害虫の発生期間に適合させて性フェロモンを放出することができる性フェロモンの徐放性製剤及びその防除方法を提供する。【解決手段】炭素数10~20の脂肪族誘導体の性フェロモン物質を少なくも2つ以上含有する性フェロモン徐放性製剤であって、該脂肪族誘導体のうち、官能基の炭素数を含めない炭素数が最少の性フェロモン物質の一部又は全部が含まれる高分子材料の第1室と、残りの性フェロモン物質が含まれる高分子材料の第2室を備えてなる性フェロモン徐放性製剤を提供する。また、この性フェロモン徐放性製剤を用いる防除方法を提供する。【選択図】 なし
