[Background Art] [Problems to be Solved by the Invention] Mammals such as mice and moles that cause harm to conventional agriculture, and insect pests such as beetles, as well as the extension of residential land to habitat of wild animals and bait Since the decrease in the number of animals brought animals closer to the daily lives of humans, wild animals, raccoon dogs, monkeys, and deer insects have become animals that cause harm to humans. In addition, irresponsible breeding of human beings makes pets wild and breeds, and the number of animals that cause harm to humans is increasing.
In recent years, fecal damage caused by the domestication of domestic pigeons has frequently occurred in shrines and temples, public facilities, residential condominiums, etc., and has become one of the serious pollution problems. Conventionally, many methods of avoiding harmful birds appeal to the eyes and eyes such as reflected light and explosion sound. In addition, drug killing, which is considered to be the most effective, is difficult from the viewpoint of animal welfare, and the number of individuals is regulated by the use of contraceptives, but in the case of contraceptives, the effects are extremely short due to various chemical characteristics. However, long-term effects cannot be expected.

Means such as individual dispersion by the use of repellents have also been used, but as repellent substances so far, in addition to essential oils such as spearmint oil, bornyl acetate, camphor, and tetrahydrothiophene and terpenes, pesticides. It is known that a sulfur-containing compound such as thiuram, which is a bactericide, is excellent and effective. However, repellents cannot be said to be a positive means, and because they are not radical methods, systematic studies have not been conducted. It is expected that the development of repellents with more excellent lasting effects will be utilized as one of the most important spot-based control in consideration of human livestock and the surrounding environment. As a result of diligently searching for repellent substances from such a viewpoint, it was found that sulfur-containing terpene compounds and 6- to 8-membered heterocyclic compounds having S and O as ring members exhibit repellent activity.

[0004]

The repellent substance of the present invention is a sulfur-containing terpene compound or 6 to 8 having S and O as ring members.
Member heterocyclic compound as an active ingredient, preferably the sulfur-containing terpene compound is thiogeraniol, 8-mercaptomenthone, limonenethiol or mint sulfide, the sulfur-containing heterocyclic compound is 2-methyl-4-propyl-1, It is 3-oxathian. The compounds used in the present invention are known compounds, and these compounds are commercially available.

BEST MODE FOR CARRYING OUT THE INVENTION Repellents are substances used to keep animals that cause harm away from them. The sulfur-containing terpene is a terpene containing S (sulfur atom), and the terpene is a general term for aromatic compounds that are the main components of plant essential oils, and generally has a skeleton composed of 5n carbon atoms, and n =
Those with 2, 3, 4, 6 are called monoterpenes, sesquiterpenes, diterpenes and triterpenes. Some have a chain structure and some have a cyclic structure. In addition to hydrocarbons, it also has functional groups such as OH, CO, COOH, and -O-.

S of the sulfur-containing terpene of the present invention is contained in the functional group of the terpene and is preferably present as an SH group or as a ring-constituting atom. More preferably, it is a monoterpene thiol compound. Specific examples of the sulfur-containing terpene compound that can be used in the present invention include thiogeraniol (I) (3,7-dimethyl-2,6-octadiene-
1-thiol), 8-mercaptomenthone (II) (2-
(1-mercapto-1-methyl) -ethyl-5-methyl-cyclohexanone), limonenethiol (III) (α,
α, 4-trimethyl-3-cyclohexene-1-methanethiol) and mint sulfide (IV) ((1R)-
Cis-2,6-epithio-cis-8-isopropyl-1
-Methyl-5-methylene-cis-bicyclo [5,3,0]
Decane), or mixtures thereof. Preferred is thiogeraniol, 8-mercaptomenthone or limonene thiol, and more preferred is thiogeraniol.

The 6- to 8-membered heterocyclic compound having S and O as ring members of the present invention has 6 to 12 carbon atoms, and at least one S and O (oxygen atom) is a constituent atom of the ring. Which is a 6- to 8-membered ring compound and may have a substituent. Preferably, S and O having 6 to 12 carbon atoms.
It is a 6-membered ring compound containing. Specifically, 2-methyl-4
-Propyl-1,3-oxathiane (V) (cis and trans) can be mentioned.

These sulfur-containing terpenes or 6- to 8-membered heterocyclic compounds having S and O as ring members are contained in natural fragrances in a trace amount, and even if they are nontoxic or extremely low, they are in repellents. Can be included in any desired amount.

The repellents of the present invention include liquids, powders, suspensions,
It can be formulated into a form such as a spray, a granule and a tablet, and these may be prepared by a usual method using the sulfur-containing compound of the present invention and the additives usually used for the preparation.

Further, the sulfur-containing compound may be gelled together with a natural or synthetic polymer substance or may be mixed with an ultraviolet curable resin to give a solid agent. It can also be adsorbed on activated carbon and formulated as a powder.

The liquid agent can be made into a product by impregnating a synthetic resin or an inorganic porous material and treating it in the same manner as granules and the like. Examples of these inorganic porous materials include calcium silicate, silica gel, and attapulgite (trade name, manufactured by Kagaku Kagaku Kogyo Co., Ltd.).
This is filled in a bag made of a material having air permeability such as nonwoven fabric. Further, the liquid agent can be formulated into a bag in which a perfume-permeable polymer is used as an inner surface in a liquid state or by being impregnated with cellulose.

Particularly when the sulfur-containing compound has high volatility,
In order to suppress the volatility of the sulfur-containing compound and maintain the repellent effect for a long period of time, it is prepared by adding a retaining agent having a retaining effect. Examples of these suspending agents include benzyl benzoate, diethyl phthalate, limonene dimer hydrate, isopropyl myristate, dipropylene glycol and hexylene glycol. Usually, these holding agents are added in an amount of 0.2 to 6 parts by weight, preferably 0.5 to 3 parts by weight, more preferably 1 to 2 parts by weight, based on 1 part by weight of the sulfur-containing compound.

The amount of the formulated repellent is appropriately determined and set in consideration of the target animal, the time of use, the place of use, the temperature of the place, the air volume, and the like.

Repellent activity of sulfur-containing terpenes for cats Method: An experimental enclosure with a side length of 5 m was set in which 0.5-1.0 was placed.
Two females and two males were released. On the other hand, an activated carbon-containing mat (square with a side of 3 cm and thickness of 0.5 cm) impregnated with 5 ml of a 10,000 ppm ethanol solution of each test sample was placed on the center of the enclosure, and baits were placed around it. The subject was evaluated based on the food intake state when a mat impregnated with ethanol alone was placed on the floor. For comparison, the brand name by by cat stock solution was used.
