Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for controlling insect pests, a method for inhibiting the growth of clothes pests, and an agent for killing clothes pests. More particularly, the present invention relates to the mating of clothes pests and the propagation of hatches from eggs. The present invention relates to an insect repellent method, a growth inhibitor and an ovicidal agent which can effectively inhibit an act or a breeding activity and have an excellent ovicidal action.

[0002]

2. Description of the Related Art Conventionally, a large number of various substances are known as insecticides or insect repellents against pests. A very large number of substances ranging from synthetic chemical substances to natural substances are used as insecticides or insect repellents, Those suitable for the intended use are selected and used. For outdoor wide areas, strong ones are used so that only a small amount is needed, and weak ones are selected indoors so as not to affect the human body. Those that are used in an enclosed space do not need to be so powerful, but rather those that are small and effective for a long time were considered suitable.

[0003] Various compounds have also been proposed for clothing pests, and a fiber pest repellent containing a specific compound as an active ingredient is used to prevent the pests from penetrating into textile products, thereby improving the effect of preventing food damage. It has gained. For clothing, pesticides and pesticides are selected and used because they must be effective in a small amount and for a long time.

[0004]

Substances conventionally known as insecticides or insect repellents against insect pests are generally considered to be effective against clothing pests, but even if effective, they can be used practically. Not something. Because clothing is the target, anything that smells clothing is not suitable,
It should not discolor or decolor the fibers or dyes of the clothing. In addition, in situations where the insecticidal effect is not perfect with conventional products in situations where it is used for a long time in a closet or closet, mating, spawning, etc. may be performed at that location, causing harm to clothing. Yes, inadequate. This is because, in a closet or clothes box, clothing is hung side by side and placed on top of each other, so that clothing is so close to each other that even if the drug volatilizes, it will not enter between the close parts. It is hard to act on pests.

[0005] Furthermore, so that a considerable amount of drug is volatilized,
Even when the drug is placed, the fibers of the clothing itself are porous substances and have a strong adsorbing power, so that the drug is absorbed by the clothing fibers before the drug spreads and spreads between close parts of the clothing. The pests will inevitably survive. If any pest survives, it will propagate, and as the amount of drug decreases over time, the pest will spread throughout its area. In order to prevent this situation, it is necessary to put a considerable amount of insecticide throughout the closet and the clothes box. Therefore, it is desirable to be able to prevent the harm of clothing pests without using such a large amount of chemicals.

[0006]

Means for Solving the Problems The present inventor has studied means for preventing the harm of clothing pests without using a strong insecticide. As for harm to clothing, "egg-hatching-larva-adult-mating-
In the "spawning" cycle, hatched larvae are known to damage clothing. Thus, in order to prevent food damage to clothing, it was not always necessary to completely kill adults and even eggs, and it was conceived that minimum larvae should not be hatched. Therefore, in order to prevent larvae from hatching, it is necessary to prevent any stage of adult mating, spawning, and even hatching from eggs, or to kill the eggs themselves, In short, it suffices to inhibit the propagation of clothing pests. The present inventors have studied the substances that inhibit the proliferation action of the clothing pests, and found that some terpene compounds have the property of inhibiting the proliferation action, and completed the present invention.

The present invention has solved the above-mentioned problems by the following means. (1) A method for controlling insect pests of clothing, comprising using a terpene compound as an active ingredient. (2) A clothing pest growth inhibitor comprising a terpene compound as an active ingredient. (3) The growth inhibitor of clothing pests according to (2), wherein the terpene compound is an alcohol, aldehyde, ether, ketone, or pyran. (4) An insecticide for clothing pests, characterized by comprising at least one of carvone and its isomer as an active ingredient. That is, the present invention comprises a terpene compound as an active ingredient, and inhibits mating of clothing pests, inhibits proliferation of insects such as hatching from eggs, etc. It provides an ovicidal agent. Here, the term “proliferation inhibition” refers to “inhibition of the propagation of insects, such as mating, laying eggs, and hatching from eggs”.

Hitherto, it has long been known that the above-mentioned natural essential oils and flavor components are effective as insecticides or insect repellents, and various studies have been made. For example, against mites in the house, organic solvent extracts of plants such as sapling, hinoki, pinaceae, etc. have extermination ability, repellent effect, and volatile terpene compounds in essential oils etc. It is known to have lethal and repellent effects. In addition, acaricides, insecticides, and repellents containing benzaldehyde, perilaldehyde, 1-carboxylic acid and the like as active ingredients are known. However, they exhibit excellent insecticidal efficacy mainly against ticks, and are used as agents that act as insecticides or repellents. Therefore, the amount used or the effective amount is as an insecticide or repellent, and there has been no new use in the present invention.

[0009]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Effective terpene compounds used in the present invention are, for example, alcohols, aldehydes, ethers, ketones and pyranes. Specifically, it is as follows. Alcohols: linalool, citronellol, geraniol, α-terpineol, isopulegol, thymol, eugenol Aldehydes: decylaldehyde, citral, perilaldehyde Ethers: anethole, 1,8-cineole Pyrans: rose oxide ketones: carvone (d-form) , L-form, dl-form), menthone and the like. These include various isomers, and one or more of them can be used in combination. These compounds have an action such as copulation inhibition, invasion inhibition, and eclosion inhibition against clothing pests such as moth and moth. Among them, carvone is also excellent in ovicidal action.

The amount of use depends on the place where it is used. For example, in the case of a closet, 2 to 1 per m ³ is used.
000 mg, preferably 10 to 200 mg. In the case of a garment case, the amount is 0.5 to 500 mg, preferably 5 to 100 mg per 1 m ³ . The form of use of the drug, that is, the dosage form, can be any of mat, sheet, film, gel, powder, granule, tablet, honeycomb, liquid-absorbent core, etc. Is preferred.
