本発明の匍匐害虫忌避剤並びに匍匐害虫の忌避方法は、匍匐害虫に対する忌避効果と人畜に対する安全性に優れ、匂いもそれほど強くなく使い易いので、その実用性は極めて高い。 The pest-repellent repellent and the method for repelling pests of the present invention are excellent in practicality because they are excellent in repellent effect on pest-insects and safety for human animals, and are not so strong and easy to use.
本発明の匍匐害虫忌避剤は、匍匐害虫忌避成分として、ｐ−メンタン−３，８−ジオール及び／又はｐ−メンタン−１，８−ジオールを担持する。
ｐ−メンタン−３，８−ジオール及び／又はｐ−メンタン−１，８−ジオールは、レモンユーカリの精油に含まれる物質で、蚊などの飛翔害虫用忌避剤の忌避成分として公知であるが、ゴキブリなどの匍匐害虫に対する忌避効果に付いては、これまで検討された報告はない。
一方、ｐ−メンタン−１，８−ジオールについても、蚊に対して若干の忌避効果を示すと言われているものの、従来それほど注目されていなかった。
The pest repellent of the present invention carries p-menthane-3,8-diol and / or p-menthane-1,8-diol as a pest repellent component.
p-menthane-3,8-diol and / or p-menthane-1,8-diol is a substance contained in the essential oil of lemon eucalyptus, and is known as a repellent component of flying insect repellents such as mosquitoes, There have been no reports on the repellent effect against cockroaches such as cockroaches.
On the other hand, although p-menthane-1,8-diol is also said to show some repellent effect against mosquitoes, it has not received much attention.
しかるに、本発明者らは、これらの化合物の匍匐害虫に対する忌避効果を鋭意検討し、試験の結果、テルペン系化合物のなかでは特に優れた匍匐害虫忌避効果を奏することを見出したものである。そして、これらの化合物は、人畜に対して安全性が高く、匂いも弱いことから使い易いというメリットも有する。 However, the present inventors have intensively studied the repellent effect of these compounds against worms, and as a result of the test, they have found that the terpene compounds exhibit particularly excellent worm repellent effects. And these compounds have the merit that they are easy to use because they are highly safe for human animals and have a weak odor.
従来の知見によれば、例えば、メントール（ｐ−メンタン−３，８−ジオールの８位の水酸基が水素原子の化合物）は、飛翔害虫にある程度の忌避効果を示すが、ゴキブリに対する忌避効果は低い。本発明者らは、シクロヘキサン環の８位の水酸基が、詳細な理由は不明ながら、匍匐害虫に対する忌避効果発現に極めて重要な役割を果たすことを知見し、本発明を完成するに至った。 According to conventional knowledge, for example, menthol (a compound in which the hydroxyl group at the 8-position of p-menthane-3,8-diol is a hydrogen atom) exhibits a certain amount of repellent effect on flying insects, but has a low repellent effect on cockroaches. . The present inventors have found that the hydroxyl group at the 8-position of the cyclohexane ring plays an extremely important role in the expression of the repellent effect against worms, although the detailed reason is unknown, and have completed the present invention.
本発明の匍匐害虫忌避剤は、上記匍匐害虫忌避成分のみで構成しても構わないが、通常、各種の成分を加えて種々の形態に調製され、匍匐害虫忌避成分の含有量や忌避剤全体量に対する比率は、忌避剤の形態によって変化しうる。例えば、液剤のような液状である場合は、０．２〜２０質量％程度に設定するのが好ましい。０．２質量％未満であると忌避効果が十分でなく、一方、２０質量％を超えるとベタつき感が出るなど実用的でない。
また、担体に担持させるような形態の場合、１ｃｍ2当り０．０１〜１００ｍｇ／ｃｍ2担持させると伴に、当該匍匐害虫忌避成分の２４時間当りの揮散量を０．２〜２００ｍｇの範囲に調整するのが適当である。
The pest repellent of the present invention may be composed only of the above pest repellent component, but is usually prepared in various forms by adding various components, and the content of the pest repellent component and the whole repellent The ratio to the amount can vary depending on the form of the repellent. For example, when it is liquid like a liquid agent, it is preferable to set to about 0.2 to 20% by mass. If the amount is less than 0.2% by mass, the repellent effect is not sufficient, while if it exceeds 20% by mass, a sticky feeling is produced, which is not practical.
Also, if the form as carried on the carrier, the companion when is 1 cm 2 per 0.01 - 100 / cm 2 carrying the volatilization amount per 24 hours of the crawling pest repellent component in the range of 0.2~200mg It is appropriate to adjust.
本発明では、好ましくは、ｐ−メンタン−３，８−ジオール及び／又はｐ−メンタン−１，８−ジオールと、更に、沸点の中央値が１６０〜２５０℃である溶剤を効力増強剤として配合する。このような溶剤としては、グリコール、グリコールエーテル、脂肪族炭化水素系溶剤等が挙げられ、特に、グリコール、グリコールエーテル、灯油が好ましい。
具体的には、プロピレングリコール、１，３−ブチレングリコール、１，２−ヘキサンジオール、ジエチレングリコールモノブチルエーテル、プロピレングリコールモノブチルエーテル、ジプロピレングリコールモノメチルエーテル、１−メトキシ−１，２−プロパンジオール等を例示できるが、これらに限定されない。
In the present invention, preferably, p-menthane-3,8-diol and / or p-menthane-1,8-diol and a solvent having a median boiling point of 160 to 250 ° C. are blended as efficacy enhancers. To do. Examples of such solvents include glycols, glycol ethers, aliphatic hydrocarbon solvents, and glycols, glycol ethers, and kerosene are particularly preferable.
Specific examples include propylene glycol, 1,3-butylene glycol, 1,2-hexanediol, diethylene glycol monobutyl ether, propylene glycol monobutyl ether, dipropylene glycol monomethyl ether, 1-methoxy-1,2-propanediol and the like. Although it can, it is not limited to these.
ピレスロイド系殺虫成分に、グリコールやグリコールエーテルを配合してゴキブリに噴霧施用すると、一般に皮膚浸透性が悪くなり殺虫効果の低下を招くことが知られている。一方、本発明のｐ−メンタン−３，８−ジオール及び／又はｐ−メンタン−１，８−ジオールに基づく忌避効果では、グリコールやグリコールエーテルは対照的に効力増強剤として作用することが認められた。これは、匍匐害虫忌避成分の場合、その揮散性が殺虫成分の場合と異なる形で忌避作用に大きく関与し、ｐ−メンタン−３，８−ジオール及び／又はｐ−メンタン−１，８−ジオールと、沸点の中央値が１６０〜２５０℃である、特にグリコール、グリコールエーテル系溶媒や灯油との組み合わせが作用発現に特に効果的なためと推察される。なお、効力増強剤の配合量は、匍匐害虫忌避成分の０．５倍量以上、好ましくは、２．０〜５０倍量が適当である。 It is known that when a pyrethroid-based insecticidal component is blended with glycol or glycol ether and sprayed on cockroaches, skin permeability is generally deteriorated and the insecticidal effect is reduced. On the other hand, in the repellent effect based on p-menthane-3,8-diol and / or p-menthane-1,8-diol of the present invention, it is recognized that glycol and glycol ether, in contrast, act as an efficacy enhancer. It was. This is because, in the case of a pest repellent component, its volatility is greatly related to the repellent action in a form different from that of the insecticidal component, and p-menthan-3,8-diol and / or p-menthan-1,8-diol It is presumed that the median boiling point is 160 to 250 ° C., and particularly a combination of glycol, glycol ether solvent or kerosene is particularly effective for action expression. In addition, the compounding amount of the efficacy enhancer is 0.5 times or more, preferably 2.0 to 50 times the amount of the pest repellent component.
本発明の匍匐害虫忌避剤は、忌避効果と人畜に対する安全性に支障を来たさない限りにおいて、ディート、他のテルペン系化合物や天然精油、例えば、ヨノン、アリルヨノン、ダマスコン、シトロネラール、シトロネロール、シトラール、リナロール、テルピネオール、メントール、ジメチルフェニルエチルカルビトール、メンタン、カンフェン、メチルサリシレート、ピネン、リモネン、ゲラニオール、ボルネオール、ゲラニルフォーメート、シトロネラ油、シナモン油、ヒバ油、ラベンダー油、オレンジ油、グレープフルーツ油、シダーウッド油、ゼラニウム油、タイムホワイト油、ハッカ油などを配合しても構わない。なかでも、高い相乗的な忌避効果を期待できる点で、ヨノン、アリルヨノン、ダマスコンが好適である。
また、緑茶抽出物や柿抽出物のような植物由来の消臭成分や、香調の調整のために他の芳香成分を配合してもよく、例えば、「緑の香り」と呼ばれる青葉アルコールや青葉アルデヒド等を添加してリラックス効果を付与することができる。
The pest repellent of the present invention is a diet, other terpene compound or natural essential oil, for example, nonone, allylonone, damascon, citronellal, citronellal, citronellol, citral, as long as the repellent effect and safety for human livestock are not hindered. , Linalool, terpineol, menthol, dimethylphenylethyl carbitol, menthane, camphene, methyl salicylate, pinene, limonene, geraniol, borneol, geranyl formate, citronella oil, cinnamon oil, hiba oil, lavender oil, orange oil, grapefruit oil, Cedarwood oil, geranium oil, thyme white oil, peppermint oil, etc. may be blended. Of these, yoon, allyl yonon, and damascon are preferred because they can be expected to have a high synergistic repellent effect.
In addition, plant-derived deodorant components such as green tea extract and koji extract, and other fragrance components for adjusting the fragrance may be blended. For example, green leaf alcohol called “green fragrance” Green leaf aldehyde etc. can be added and the relaxation effect can be provided.
更に、常温揮散性のピレスロイド系殺虫成分、例えば、エムペントリン、２，３，５，６−テトラフルオロベンジル−２，２−ジメチル−３−（２，２−ジクロロビニル）シクロプロパンカルボキシレート［トランスフルトリン］、４−メチル−２，３，５，６−テトラフルオロベンジル−２，２−ジメチル−３−（１−プロペニル）シクロプロパンカルボキシレート、４−メトキシメチル−２，３，５，６−テトラフルオロベンジル−２，２−ジメチル−３−（１−プロペニル）シクロプロパンカルボキシレートなどを添加すれば忌避効果を増強させることも可能となる。 Further, room temperature volatile pyrethroid insecticides such as empentrin, 2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (2,2-dichlorovinyl) cyclopropanecarboxylate [Transflu Thrin], 4-methyl-2,3,5,6-tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate, 4-methoxymethyl-2,3,5,6- Addition of tetrafluorobenzyl-2,2-dimethyl-3- (1-propenyl) cyclopropanecarboxylate or the like can enhance the repellent effect.
