Abstract

PURPOSE:To stabilize a sex pheromone compound by adding a specific catechol derivative and a specific benzotriazole derivative to a higher aliphatic pheromone having unsaturated double bond and mixing these derivative. CONSTITUTION:A catechol derivative (e.g. catechol or p-tert. butyl catechol) expressed by formula I (R<1> to R<4> are H, tert. butyl or 1-5C alkyl) and benzotriazole derivative [e.g. 2-(2-hydroxy-5'-methylphenyl)benzotriazole] expressed by formula II (X is H or Cl; R<5> is H, tert. butyl or tert. amyl; R<6> is methyl, tert. butyl or tert. amyl) are each added to a sex pheromone compound at amounts of about 0.1-20wt.% to stabilize the sex pheromone compound.

2. Description of the Related Art In recent years, pesticides such as pesticides are highly toxic to those who handle them and have developed into one social problem. In order to deal with this problem, a biological pest control method has been studied, and as one of the methods, a communication disturbance control method that chemically synthesizes a sex pheromone released by a female pest and uses it is proposed. Has been done. In this control method, Japanese Patent Publication Sho 61
It is necessary to release a constant amount of sex pheromone for a long period of time like the sustained release form described in JP-A-16361. However, most of the sex pheromone substances of Lepidoptera pests are higher aliphatic derivatives having unsaturated double bonds, so that the double bonds can be easily oxidized, isomerized and polymerized when left in the field for a long time. 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 in the preparation has been proposed. For example, Journal

It has been reported that the stability is further improved by using and adding to the sex pheromone substance. Certainly, with certain antioxidants and UV absorbers, mixed use is more effective than single use in improving the stability of the sex pheromone compound having an unsaturated double bond. It is not known what combination of absorbents would be most effective.

In general, catechol compounds are effective not only for antioxidants such as double bonds in sex pheromone compounds but also for polymerization and isomerization, as compared with antioxidants such as butylhydroxytoluene, butylhydroxyanisole, and vitamin E. . However, even if it is used alone, it is not sufficiently effective in direct sunlight in the open air. Then, the present inventors have examined the ultraviolet absorber that can exert the most effect by mixing with these catechol compounds, and found that the combination with the benzotriazole derivative represented by the general formula 4 is optimal.

However, depending on the type of higher aliphatic pheromone compound having an unsaturated double bond to be applied, the solubility of these benzotriazole derivatives having a short molecular chain is low, and it becomes difficult to secure a sufficient stabilizing effect. Therefore, in such a case, it is desirable to use one having a long molecular chain such as t-butyl group or t-amyl group. The use amount of these catechol derivative and benzotriazole derivative is required to be 0.1% or more based on the sex pheromone compound, and if the amount is less than this amount, the effect is small, and even if it is used in an amount of 20% by weight or more, further improvement of the effect cannot be expected.

EXAMPLES Hereinafter, specific embodiments of the present invention will be described with reference to Examples and Comparative Examples, but the present invention is not limited thereto. A mixture of the sex pheromone compound shown in Table 1 and a stabilizer in a glass tube having an inner diameter of 1 mm, an outer diameter of 2 mm and a length of 20 cm.
After filling 100 g, both ends were plugged and exposed to direct sunlight in the field for 6 to 3 months. Then, the mixture was opened and the mixture was taken out, and the amount of the sex pheromone remaining without denaturation was quantified by internal standard method gas chromatography to determine the residual ratio with respect to the sex pheromone at the time of filling. From Table 1, it was found that the combination of the examples had a higher survival rate of the sex pheromone than the comparative example and had a remarkable stabilizing effect.
