Description

The present invention relates to a repellent and a repellent method against harmful insects such as cockroaches, flies (such as house flies, Drosophila, butterflies, etc.), mosquitoes, flyfish, and flies.
More specifically, the present invention provides at least one compound selected from cyclic monoterpene alcohols and / or compounds selected from cyclic monoterpene ketones and compounds selected from cyclic sesquiterpenes. The present invention relates to an insect repellent characterized by containing a combination as an active ingredient, and a repellent method using the same.

  Harmful insects such as cockroaches, flies (fly, Drosophila, butterfly, etc.), mosquitoes, flyfish, and flies are not only stinging and making them uncomfortable, but they also cause problems such as being a vector of pathogens and their control Is desired.

  Many insecticides have been proposed for these harmful insects, and organophosphorus, carbamate, and pyrethroid insecticides have excellent insecticidal power and are inexpensive and are now widely used. ing. However, these insecticides are concerned about direct effects on the human body, adhesion to food and agricultural products, and effects on the ecosystem due to residues in soil, etc. This processing is also troublesome.

For this reason, there is a great demand for repellents. For example, conventionally, repellents containing diet (N, N-diethyl-m-toluamide) have been applied to the skin surface against flying pests such as mosquitoes, flyfish and flies. Although the method of applying to the surface has been widely used, Diet has a peculiar off-flavor and has a somewhat low volatility, so that a sufficient spatial repellent effect cannot be expected.
In order to improve the off-flavor, a pest repellent composition for human body with a reduced concentration of diet has also been proposed (Patent Document 1), but the effect persistence is not sufficient.

  In addition, some volatile natural essential oils and repellents using their constituent components have been proposed as repellent components. For example, a cockroach repellent characterized by containing a monoterpenoid having a specific group such as an isopropyl group in the molecule (Patent Document 2), a fly repellent and a mosquito repellent characterized by containing limonene as an active ingredient (Patent Document 3) is known, but the repelling effect is not sufficient, and the sustainability of the effect is not satisfactory. Furthermore, in order to improve the repellent effect, it is also proposed to use a modified product of a specific terpenoid compound (Patent Document 4) or to use a combination of multiple components. For example, a specific terpenoid compound monomer or / and a low polymerization thereof. Or a harmful animal repellent composition comprising a low-copolymerization oligomer and a low-copolymerization oligomer of these terpenoid monomers and a compound selected from phenolic, styrene-based, vinylic, maleic, and monomers (Patent Literature) 5) etc. are known, but these require chemical synthesis of the components, and it takes time to prepare the components.

In the result of the repelling of German cockroaches in Test Example 5 (Table 6), regarding the comparison of the repelling rate after 24 hours, the cyclic monoterpene alcohol and the cyclic monoterpene ketones were repelled after 24 hours alone. Since the rate is high (around 100%), the synergistic effect of the combined use (comparative example) is unknown, but when the repellency rate after 8 hours is compared, the repellency effect is the same as in Test Example 1 to Test Example 4. Showed a trend.
In other words, all the combinations of the present invention exhibited a repellent effect earlier than when only a single terpene was used, had a large repellent effect, and a synergistic effect due to the combined use was recognized.
By using cyclic sesquiterpenes alone, which have no repellent effect after 8 hours and have a low repellent rate after 24 hours, the repellent rate after 8 hours of the whole combination is improved, and 24 hours later The result that the repellent effect is also highly sustained is a great effect that exceeds expectations.
