Title: Method for stabilizing a sex pheromone compound

Abstract: An efficient method is proposed for the stabilization of a sex pheromone compound of insect pest, which is a long-chain aliphatic unsaturated ester, alcohol, ketone or hydrocarbon compound having at least ten carbon atoms and at least one double bond in a molecule, used in pest control. The method comprises admixing the compound with 2-(2'-hydroxy-5'-methylphenyl) benzotriazole and an antioxidant which is preferably a hydroquinone compound such as tert-butyl hydroquinone, 2,5-di-tert-butyl hydroquinone and 2,5-di-tert-amyl hydroquinone.
