Description of the Related Art Attempts to use repellent substances for controlling agricultural pests and sanitary pests have been made for a long time, and many natural products have been used. Recently, the relationship between the life of living organisms and essential oils of plants has become known, and it has been clarified that various terpenoids contained in plant components are repellent to certain insects. It is being defeated. For example, it has been reported that the monoterpenoids menthol and citronellal are repellent to mosquitoes, and linalool, geraniol, menthol and the like are repellent to cockroaches (Japanese Patent Laid-Open No. 53-86021 and Shin Inazuka). 1: Journal of Japan Society of Pesticides, 7 (2), 145 (19)

Therefore, by converting these compounds to compounds having an amide group, it was possible to further enhance the activity and the durability. However, among the terpenylamide compounds, the repellent activity, the exterminating activity, and their persistence were found to be different depending on the terpene skeleton. That is, it was the compound based on the limonene skeleton that showed excellent activity and durability in the secondary screening test that was actually applied to human skin. In addition, DEET and the compound of the present invention have an amide group and an ethyl group as structurally common sites. This analog compound, N, N-diethyldiamide or N, N-diethyl [2 Since-(propoxycarbonyl) ethyl] carboxamide and the like also show high repellent activity, it is considered that this common structural site is closely related to repellent property and repellent property.

Description of the Related Art Attempts to use repellent substances for controlling agricultural pests and sanitary pests have been made for a long time, and many natural products have been used. Recently, the relationship between the life of living organisms and essential oils of plants has become known, and it has been clarified that various terpenoids contained in plant components are repellent to certain insects. It is being defeated. For example, it has been reported that the monoterpenoids menthol and citronellal are repellent to mosquitoes, and linalool, geraniol, menthol and the like are repellent to cockroaches (Japanese Patent Laid-Open No. 53-86021 and Shin Inazuka). 1: Journal of Japan Society of Pesticides, 7 (2), 145 (19)

Therefore, by converting these compounds to compounds having an amide group, it was possible to further enhance the activity and the durability. However, among the terpenylamide compounds, the repellent activity, the exterminating activity, and their persistence were found to be different depending on the terpene skeleton. That is, it was the compound based on the limonene skeleton that showed excellent activity and durability in the secondary screening test that was actually applied to human skin. In addition, DEET and the compound of the present invention have an amide group and an ethyl group as structurally common sites. This analog compound, N, N-diethyldiamide or N, N-diethyl [2 Since-(propoxycarbonyl) ethyl] carboxamide and the like also show high repellent activity, it is considered that this common structural site is closely related to repellent property and repellent property.

The mite repellent effect of (citraamide) (all N, N-diethylamide compounds) was tested. DEET was also tested for comparison. Test method: 1 g of a medium having a mite density of 10,000 / g was placed in a petri dish having a diameter of 7 cm, and allowed to stand for 3 hours until the mite became stable. On the other hand, an acetone solution (0.67%) was prepared by diluting each test agent to a prescribed concentration so that the amount of drug treated was 1 g / m 2.
