(Prior Art) In recent years, pesticides such as insecticides are highly toxic to those who handle them, and have developed into one social problem. In order to address this problem, biological pest control methods have been studied, and as one of these methods, a communication disturbance control method that chemically synthesizes the sex pheromone released by female pests and uses this is proposed. Have been. In this control method, it is necessary to release a constant amount of sex pheromone for a long period of time as in the sustained-release body described in JP-B-61-16361. However, many of the sex pheromone substances of the order Pests of Pterygium are higher aliphatic derivatives having an unsaturated double bond. There is a problem that it will be altered and the original purpose will not be achieved. In order to prevent this, a method of adding an antioxidant or an ultraviolet absorber to the preparation has been proposed. For example, Journa
l of Chemical Ecology, Vol. 14, No. 8, 1659 (1988) uses butylhydroxytoluene or butylhydroxyanisole as an antioxidant, and uses an ultraviolet absorber such as 2-hydroxy-4-methoxybenzophenone. It has been reported that the stability can be further improved by adding to a sex pheromone substance. Certainly, with certain antioxidants and UV absorbers, mixed use can help improve the stability of the sex pheromone compound having an unsaturated double bond rather than using it alone. It is not known if the combination is the most effective, such as an absorbent.

In the present invention, examples of the hydroquinone derivative represented by the above general formula I include t-butylhydroquinone, di-t-butylhydroquinone, di-t-amylhydroquinone and the like. In general, hydroquinone compounds are more effective not only for preventing oxidation but also for polymerization and isomerization of double bonds in sex pheromone compounds, as compared with antioxidants such as butylhydroxytoluene, butylhydroxyanisole and vitamin E. However, hydroquinone compounds such as hydroquinone and methylhydroquinone that do not contain a t-butyl group or a t-amyl group used in the present invention have poor compatibility with the sex pheromone, which is a higher aliphatic derivative, and exhibit their effects sufficiently. Can not. Further, even if these hydroquinone compounds are used alone, they do not exert sufficient effects under direct sunlight in the field. Thus, the present inventors have studied the ultraviolet absorber that can exhibit the most effect by mixing with these hydroquinone compounds, and found that the combination with the benzotriazole derivative represented by the general formula II is optimal. .
