Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel agent for repelling adult pests and a method for repelling adult pests using the same. More specifically, it is substantially odorless and fiber pests, such as iga, kiga, himemarukatsuobushi,
The present invention relates to a repellent for adult pests, which can prevent an adult such as a burrowing beetle from approaching a fiber product and thereby prevent damage to the textile product, and a method for repelling adult pests using the same.

[0002]

2. Description of the Related Art Conventionally, as a method for preventing the damage of textile products such as clothing by fiber pests, paradichlorobenzene, naphthalene, camphor, pyrethroid compounds and the like have been used as insect repellents. These insect repellents are said to act on larvae of fiber pests and have effects such as feeding inhibition, repellency, and insecticide.

[0003] On the other hand, the inventors of the present invention ate larvae that damage fiber products earlier, but the fiber pests lay eggs by the adult entering the fiber storage location, which hatch and larvae. Therefore, if the fiber product is placed in a condition where the adult of the fiber pest does not invade, no spawning or larva is generated, and the idea that the effect of preventing the food damage can be sufficiently expected can be obtained. And, based on this idea, as a result of searching for compounds that fiber pests repel, some terpene-based compounds, alcohol-based compounds, phenolic compounds, and aldehyde-based compounds have been found to have an effect of repelling fiber pests. (Hereinafter referred to as "adult repellent") and a method for controlling insects using the same (hereinafter referred to as "adult repellent").
2907 and JP-A-7-126110).

[0004]

However, these adult repellents are components of essential oils or fragrances and generally have a strong odor. Therefore, it is convenient for producing a product utilizing an odor, but is not suitable for producing an insect control agent having no odor. On the other hand, in recent years, consumers who have almost no odor, such as insect repellents using pyrethroid compounds, are preferred by consumers, and provide an adult repellent that is substantially odor-free and matches the taste of consumers. This is the subject of the present invention.

[0005]

The reason why adults repel essential oils and fragrance components is that they avoid smell and do not approach.
It was thought before. Therefore, it was a general view that compounds having no odor also had no adult repellent effect. In contrast, the present inventors have conducted extensive searches for a wider range of compounds, and as a result, surprisingly, 2-
Phenoxyethanol and 2-dihydroterpinyloxyethanol have almost no odor,
The present inventors have found that they have a repellent effect on adults, and have reached the present invention.

[0006] That is, the present invention provides an adult repellent containing 2-phenoxyethanol and / or 2-dihydroterpinyloxyethanol as an active ingredient.

Another object of the present invention is to provide a method for repelling adult pests, which comprises applying the above-mentioned adult repellent to textiles.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION 2-phenoxyethanol, which is one of the active ingredients of the adult repellent of the present invention, is a compound which exists naturally as a component of gyokuro, a high-grade green tea, and the like.
Industrially, it is synthesized from phenol and ethylene oxide. This compound is a colorless and transparent liquid, has almost no odor, and has an effect as an adult repellent, and can prevent an adult from entering a fiber storage location.

Further, 2-dihydroterpinyloxyethanol, which is another active ingredient of the adult repellent of the present invention, is a compound represented by the formula (I): 2- (1-methyl-1)
-(4-methylcyclohexyl) ethoxy) -ethanol. This can be produced by, for example, hydrogenating 2-terpinyloxyethanol obtained by reacting α-pinene contained in a natural essential oil such as turpentine oil with ethylene glycol.

This compound is also a colorless and transparent liquid and has an effect as an adult repellent for fiber pests, despite having almost no odor, and can prevent the adult from entering the fiber storage place. .

Note that the present inventors have previously made at least one
Compounds having at least one atom selected from an oxygen atom, a nitrogen atom or a sulfur atom outside the ring and having 15 or less carbon atoms are effective as a fiber insect pest egg hatching inhibitor (Japanese Unexamined Patent Publication No.
236302). And, 2-phenoxyethanol is a typical example of the above compound, and 2-dihydroterpinyloxyethanol is also included in the definition of the above compound. Has also been confirmed.

[0013] However, the adult repellent and the egg hatching inhibitor act on different stages of the fiber pests, and have the same purpose of preventing the damage of the fiber products. Even though both are called insect repellents, Functionally different and different agents. The mechanism of action is different between the adult repellent and the egg hatching inhibitor, and even if one of the actions is present, it cannot be said that the other action is present. The finding of an adult repellent effect in addition to the hatching inhibitory effect is a new discovery.

The above-mentioned 2-phenoxyethanol and / or
Alternatively, the preparation of an adult repellent using 2-dihydroterpinyloxyethanol (hereinafter, referred to as “the active ingredient of the present invention”) is carried out by adding an effective amount of the active ingredient of the present invention to a liquid preparation or a solid preparation, for example, by a conventional method. do it. The amount of the component of the present invention used in the formulation is not particularly limited, but is generally 0.01 g to 50 g per formulation.
It is about 0 g, preferably about 0.02 g to about 100 g.

[0015] Specifically, a liquid preparation can be prepared by directly dissolving or solubilizing the active ingredient of the present invention in an appropriate solvent. As the solvent, water, alcohols, hydrocarbons, glycol ethers and the like can be used. The prepared liquid formulation can be used as it is in a container as it is, a spray formulation, a liquid core formulation that is sucked up and volatilized by a suction wick, or a formulation that is put in a container having a permeable film and vaporized through the film. Alternatively, a gel preparation can be prepared by adding a gelling agent.

On the other hand, a solid preparation can be prepared by supporting the active ingredient of the present invention on a suitable carrier. As carriers, cellulose, rayon, polyethylene, polypropylene, polyester, polyurethane, wool, talc,
Powders, granules, tablets, sheets, mats, felts, sponges, plates, papers, woven fabrics, nonwoven fabrics, porous or non-porous carriers such as clay, unglazed, ceramic powders, etc., triisopropyltrioxane, cyclododecane And other sublimable carriers. Examples of the method of supporting the carrier include dripping, spraying, spraying, impregnation, coating, printing, kneading, and the like.
The solid preparation can also be a preparation contained in a plastic case or a non-woven bag, or a garment cover-like preparation.

In preparing the adult repellent of the present invention,
If necessary, it can be used together with other insect repellents such as pyrethroid compounds. In addition, if necessary, optional components such as a fungicide, an antioxidant, and an ultraviolet absorber can be added. Furthermore, if a fragrance is appropriately added, an insect repellent having a slight scent or a pleasant scent can be obtained. Each of the active ingredients of the present invention has excellent properties as a solvent, and is therefore suitable for dissolving optional ingredients.

The adult repellent of the present invention thus obtained is
It has almost no odor and does not cause any odor during use, that is, it has substantially no odor. This adult repellent is applied to stored textiles,
It may be used so that the adult fiber pest does not approach. As a specific usage method, in addition to using liquid preparations or solid preparations in closed containers such as closets, drawers, costume cases, placing them near textiles, placing them at the entrance of closets, impregnating with repellents There is a method of providing a curtain or the like to prevent the fiber pest adult from entering the closet, a method of spraying a liquid or spray-like adult repellent on the fiber product, and the like.

[0019]

The adult repellent of the present invention has an excellent adult repellent effect of fiber pests despite substantially no odor. Therefore, by using this, adults can be repelled, and as a result, it is possible to prevent the spawning of the adults and the larvae on the textile products, and since it is substantially free of odor, Odor can also be prevented.

[0020]

Next, the present invention will be described in more detail with reference to examples, but the present invention is not limited to these examples.

Example 1 Adult repellent effect of 2-phenoxyethanol: 250 mg of 2-phenoxyethanol was 55 mm long and 60 m wide.
m of a cellulose porous carrier to obtain an adult repellent. When this insect repellent was checked for odor,
It had almost no smell.

Next, the insect repellent effect of the adult repellent was examined by the following method. As a result, when no adult repellent was used, invasion of 12 adults was observed in the costume case, whereas when two adult repellents were placed on clothing, no invasion was observed. I couldn't.

(Test Method) A commercially available plastic drawer-type outfit case was placed in a cubic enclosure with each ridge having a length of 1 m. The enclosure was made of a steel pipe framed with a plastic film. On the other hand, the outer dimensions of the installed costume case are 43 cm in width, 64 cm in depth, and 23 cm in height, and there is a gap of 5 mm between the upper part of the front drawer and the outer frame. In this costume case,
Cloth made of wool covered with black felt was put in, and kept in a constant temperature room at 25 ° C. for 10 days, and then 50 males and females of Iga adults one day after emergence were put in the enclosure. The temperature was further maintained for 7 days, and the number of adults that had invaded the costume case was examined.

Example 2 Adult repellent effect of 2-dihydroterpinyloxyethanol: In the same experiment as in Example 1, 2-phenoxyethanol was used instead of 2-phenoxyethanol (Nippon Terpene Chemical Co., Ltd.) The same applies to the reference examples)
Was used to impregnate a porous carrier made of cellulose with a length of 60 mm and a width of 70 mm to obtain an adult repellent. This adult repellent,
Almost no smell. As a result of a test performed in the same manner as in Example 1, the number of invading adults was 1 when no adult repellent was placed.
