Description

【0001】
【産業上の利用分野】
本発明はアリ類の忌避剤に関する。
【0002】
【従来の技術】
従来、ハエ、カ、ゴキブリ等の衛生害虫の忌避剤としては、ピレスロイド系殺虫剤、有機リン系殺虫剤を始めとする多くの殺虫剤が知られている。
しかし、近年、アリやヤスデのような、衛生害虫の範疇に入らない生物が不快害虫として駆除の対象となってきている。そのため、これらの不快害虫の忌避剤としても前記殺虫剤を利用しているが、満足できる忌避効果を示すものは見うけられない。また、屋外のみならず家屋内も駆除対象区域となってきているため、家具類など人が直接触れる物に対しても前記した殺虫剤が適用されるため、その毒性や環境汚染が問題となっている。
【0003】
上記のような問題から、最近、天然精油又はその成分による忌避剤が提案されている。しかしながら、天然精油については、前記衛生害虫に対する忌避剤としての提案は数多くなされているが、アリ類に対してその有効性が確認されている物質ははるかに少なく、しかも効力的に満足できる忌避剤は見うけられない。
アリ類の忌避剤としては、例えば、特開平1−294601号公報及び特開平4−288003号公報には天然テルペノイドモノマー、これらの低重合オリゴマー又は低共重合オリゴマーがイエシロアリに対して忌避効果を示すことが開示されており、特開平4−321613号公報にはカヤツリグサ科植物からの抽出物がアズマオオズアカアリに対して忌避効果を示すことが開示されている。また、特開平4−321613号公報にはボルネオール又はイソボルネオールがアリの方向感覚を狂わす効果を有することが記載されている。
これらの化合物は安全性の点では評価できるが、忌避効力の点においては未だ満足すべきものではなかった。
【0004】
ところで、害虫忌避剤としては一般にN,N−ジエチル−m−トルアミド(以下、DEETと略称する)が多用されており、アリに対しても同様に忌避剤として有効に用いることができる。
しかしながら、DEETは合成品であり、安定供給といった面からは天然精油の方が供給し易く、安全性の面からも天然精油の方が有利なものが多い。またエアゾール剤に製剤されて、噴霧され微粒子化された場合に、鼻粘膜への刺激が認められる場合もあるといった問題もある。
【0005】
【発明が解決しようとする課題】
したがって、本発明の目的は、安全性が高く、しかもアリ類に対してDEETと同等もしくはそれに近い高い忌避効果を有し、忌避効果の持続性や低濃度でも高い忌避効果を示すことができる効力的に満足できるアリ類の忌避剤を提供することにある。
さらに本発明の目的は、上記のような高い忌避効果や安全性に優れると共に、人の臭覚に対してはマイルドな芳香を示すことにより、屋外のみならず屋内においても問題なく使用できるアリ類の忌避剤を提供することにある。
【0006】
【課題を解決するための手段】
前記目的を達成するために、本発明によれば、ダーウッド油有効成分として含有することを特徴とするアリ類の忌避剤が提供される。
さらに本発明の別の態様によれば、ダーウッド油、ピレスロイド系殺虫剤,有機リン系殺虫剤,カーバメート系殺虫剤の1種又は2種以上とを有効成分として含有することを特徴とするアリ類の忌避剤が提供される。
【0007】
【発明の作用及び態様】
本発明者らは、前記課題を解決すべく、安全性が高く、生態系のバランスをくずさないアリ忌避剤について鋭意検討した結果、天然精油であるシダーウッド油が卓越したアリ忌避効果を有することを見い出した。
上記シダーウッド油以外でも、各種植物体から得られた天然精油、例えばヒノキ科の植物体から得られたヒバ油、シプレス油、タイワンヒノキ油、ネズミサシ油、ヒノキ油、ベニヒ油;マツ科の植物体から得られたパイン油、アビエス油、テレピン油、針葉油、松根油;シソ科の植物体から得られたペニーロイヤル油;セリ科の植物体から得られたアニス油;バンレイシ科の植物から得られたイランイラン油;フトモモ科の植物から得られたユーカリ油、シトロネラ油、クローブ油等にもアリ類に対する忌避効果が認められ、上記シダーウッド油と共に併用できる。
さらに本発明者らの研究によれば、上記シダーウッド油と共に殺虫剤を併用することにより、アリ類に対する忌避効果をさらに増強できることを見い出した。上記シダーウッド油と混合して用いることができる殺虫剤としては、従来より害虫駆除剤として用いられる各種殺虫剤を用いることができ、ピレスロイド系殺虫剤、カーバメート系殺虫剤、有機リン系殺虫剤等を挙げることができるが、もちろんこれらに限定されるものではない。

[Industrial applications]
The present invention relates to ant repellents.
[0002]
[Prior art]
Conventionally, as insect repellents for sanitary pests such as flies, mosquitoes and cockroaches, many insecticides such as pyrethroid insecticides and organophosphorus insecticides are known.
However, in recent years, organisms that do not fall into the category of sanitary pests, such as ants and millipedes, have been targeted for control as unpleasant pests. For this reason, the insecticide is also used as a repellent for these unpleasant pests, but none of them show a satisfactory repellent effect. In addition, since not only outdoors but also indoors have become the target areas for extermination, the above-mentioned insecticide is applied to furniture and other objects that are directly in contact with humans, and its toxicity and environmental pollution pose a problem. ing.
[0003]
Due to the above problems, repellents using natural essential oils or components thereof have recently been proposed. However, although there have been many proposals for natural essential oils as repellents against the above-mentioned sanitary pests, there are far fewer substances that have been confirmed to be effective against ants, and yet repellents that can be effectively satisfied. Can not be seen.
As ant repellents, for example, JP-A-1-294601 and JP-A-4-288003 disclose natural terpenoid monomers, their low-polymerized oligomers or low-copolymerized oligomers, which have a repellent effect on house termites. JP-A-4-321613 discloses that an extract from a Cyperaceae plant has a repellent effect on Azuma-okazu-antai. Japanese Patent Application Laid-Open No. 4-321613 discloses that borneol or isoborneol has an effect of disturbing the sense of direction of an ant.
Although these compounds can be evaluated in terms of safety, they have not been satisfactory in terms of repellency.
[0004]
By the way, N, N-diethyl-m-toluamide (hereinafter, abbreviated as DEET) is generally widely used as a pest repellent, and can be effectively used as a repellent for ants as well.
However, DEET is a synthetic product, and natural essential oil is easier to supply in terms of stable supply, and natural essential oil is more advantageous in terms of safety in many cases. In addition, there is also a problem that irritation to the nasal mucosa may be observed when the composition is formulated into an aerosol, sprayed and atomized.
[0005]
[Problems to be solved by the invention]
Therefore, an object of the present invention is to provide a highly safe and highly repellent effect similar to or close to DEET against ants, and to exhibit a long repellent effect and a high repellent effect even at a low concentration. An object of the present invention is to provide a repellent for ants which is satisfactory in terms of ants.
Furthermore, an object of the present invention is to provide an ant that can be used not only outdoors but also indoors without any problem by exhibiting a high aversion effect and safety as described above and exhibiting a mild fragrance against human smell. It is to provide a repellent.
[0006]
[Means for Solving the Problems]

(2) Insects to be tested Insects (Pristomymex pungens) bred under constant temperature (25 ° C.) and long-day conditions (14L10D) and Tobiraokeari (Lasius niger) living outdoors were used as test insects.
(3) Test method: Filter paper contact test Toyo filter paper NO. 1A of each test agent diluted to a predetermined concentration with acetone was applied to 5A, and air-dried for 1 hour. This was cut into two semicircular pieces, and one of them was fixed to a 9 cm diameter petri dish together with untreated filter paper similarly cut into a semicircular shape with double-sided tape. From above, powdered talc was applied to the inner wall. A coated glass ring having an inner diameter of 7 cm was placed, and 10 test insects were placed therein. At 30 minutes and 60 minutes after the treatment, the number of individuals present in each area was counted, the average value was obtained, and the repellent rate was calculated by the following equation. The test was performed in duplicate and repeated twice for each run (when the first run was completed, the test insects inside were dispersed with a brush and the second run was performed).

d-T80-resmethrin 0.1% by weight
Kerosene (solvent) 43.7% by weight
LPG (propellant) 56.0% by weight
(2) Test method: Veneer plate contact test An aerosol formulation containing an insecticide and natural essential oil and an aerosol formulation containing only an insecticide were sprayed onto a 10 × 10 cm plywood from a distance of 30 cm for 3 seconds. The plywood was air-dried for 1 hour, then placed side by side, and a glass ring (7 cm inside diameter) coated with powdered talc on the inner wall was placed thereon. Five test insects were put in the test, the number of individuals present in each area was counted 5 minutes after the treatment, and this operation was repeated three times to calculate the average abundance. Table 4 shows the results.
[0025]
[ Table 4 ]
Figure 0003556981
From the results shown in Table 4, it can be seen that a sufficient repellent effect on ants cannot be obtained with the insecticide alone, but a high repellent effect can be obtained by using cedarwood oil in combination.
