Description
本発明は、半翅目ヘリカメムシ科に属するホソヘリカメムシ（学名Ｒｉｐｔｏｒｔｕｓ ｃｌａｖａｔｕｓ）の誘引剤に関する。 [Technical Field] The present invention relates to an attractant for Hosohelimera (Scientific name Riptortus clavatus) belonging to the family Hemiptera.
ホソヘリカメムシは、大豆その他豆類に大害を与えているので、誘引効果を有する物質の研究が進められている。 Hosohelikamushi is a serious harm to soybeans and other beans, so research on substances that have an attracting effect is underway.
本件出願人は、ホソヘリカメムシの誘引剤に関する技術として、（Ｅ）−２−ヘキセニル（Ｚ）−３−ヘキセノエート、（Ｅ）−２−ヘキセニル（Ｅ）−２−ヘキセノエート及びミリスチルイソブチレートを活性成分として含有する、ホソヘリカメムシ及びカメムシタマゴトビコバチの誘引剤を出願した（特許文献１）。
ホソヘリカメムシは豆類に多大な損害を与えるので、その研究は、日夜進められており、誘引効果を示す新たな物質が求められている。 As the beetle bugs cause a lot of damage to beans, the research is being carried out day and night, and a new substance showing an attractive effect is required.
従って、本発明が解決しようとする課題は、ホソヘリカメムシに対して誘引効果を示す新たな化合物を見出すことにある。 Therefore, the problem to be solved by the present invention is to find a new compound that exhibits an attracting effect on the giant bug.
本発明者らは、ホソヘリカメムシに対して誘引効果を示す新たな化合物を見出すべく、鋭意研究を続けた結果、特許文献１に記載の合成フェロモン剤を単独で使用するよりも、ダイズ種子と組み合わせたトラップに、多数のホソヘリカメムシが集合していることに着目した。 As a result of continual research to find a new compound having an attracting effect on the winged beetle, the present inventors have found that soybean seeds and the seeds are more suitable than the synthetic pheromone agent described in Patent Document 1 alone. We paid attention to the fact that a large number of stink bugs gathered in the combined traps.
そこで、その成分を抽出して特定したところ、ミリスチルイソブチレートと、（Ｅ）−２−ヘキセニルヘキサノエートとが関与していることを見出した。 Then, when the component was extracted and specified, it discovered that myristyl isobutyrate and (E) -2-hexenyl hexanoate were concerned.
ここで、（Ｅ）−２−ヘキセニルヘキサノエートは、ホソヘリカメムシに対して、警報フェロモンとして作用することが知られており（Biosci.Biotech.Biochem.,56(6),1004-1005,1992）、通常は、誘引剤の成分として用いることは考えられていなかった。 Here, it is known that (E) -2-hexenylhexanoate acts as an alarm pheromone against Hosohelikamushi (Biosci. Biotech. Biochem., 56 (6), 1004-1005, 1992), it was not normally considered to be used as an attractant component.
しかしながら、本発明者らは、各成分を合成し、その２成分を組み合わせた化合物が、意外にも、ホソヘリカメムシに対して顕著な誘引効果を有することを見出し、本発明を完成した。 However, the present inventors have synthesized each component, and found that the compound obtained by combining the two components surprisingly has a remarkable attracting effect on the giant bug, and completed the present invention.
すなわち、本発明の課題を解決するための手段は、次の通りである。 That is, the means for solving the problems of the present invention are as follows.
第１に、
ミリスチルイソブチレートと、（Ｅ）−２−ヘキセニルヘキサノエートとを含有することを特徴とする、ホソヘリカメムシの誘引剤。
第２に、
ミリスチルイソブチレートと、（Ｅ）−２−ヘキセニルヘキサノエートとを、１〜３：３〜１となるように調製した化合物を含有することを特徴とする、ホソヘリカメムシの誘引剤。
First,
An attractant for Hosohelikamushi, characterized by containing myristyl isobutyrate and (E) -2-hexenylhexanoate.
Second,
An attractant for the worm, characterized in that it comprises a compound prepared from myristyl isobutyrate and (E) -2-hexenylhexanoate in a ratio of 1-3: 3-1.
本発明にかかる誘引剤を調製するには、ミリスチルイソブチレートと、（Ｅ）−２−ヘキセニルヘキサノエートとを含有する化合物をそのまま誘引剤とする他にも、通常誘引剤の調製に際して適用されている製剤化技術を利用して、製剤化することもできる。 In order to prepare the attractant according to the present invention, the compound containing myristyl isobutyrate and (E) -2-hexenylhexanoate is used as the attractant as it is, and it is usually applied in the preparation of the attractant. It can also be formulated by using a known formulation technology.
例えば、ミリスチルイソブチレートと、（Ｅ）−２−ヘキセニルヘキサノエートとを含有する物質を、そのまま、またはジクロロメタン等の有機溶媒を用いて溶液とし、この溶液を適当なデバイス、例えば、ポリエチレン等のプラスチックやゴム等に吸着させるか、プラスチック製のカプセルや毛細態様に応じた適切な材料あるいは器具を用いて、実用的な形態の誘引剤とすることができる For example, a substance containing myristyl isobutyrate and (E) -2-hexenylhexanoate is used as it is or as a solution using an organic solvent such as dichloromethane, and this solution is used as an appropriate device, such as polyethylene. Can be adsorbed on plastics, rubber, etc., or can be made into a practical form of attractant by using plastic capsules or suitable materials or instruments according to the capillary mode
本発明によれば、ホソヘリカメムシに対して誘引効果を有する新たな物質を提供することができる。 ADVANTAGE OF THE INVENTION According to this invention, the new substance which has an attraction effect with respect to a Hosohelikamemushi can be provided.
以下に、本発明にかかる誘引剤の一実施例について説明する。 Below, one Example of the attractant concerning this invention is described.
ミリスチルイソブチレート［ＭＩ］と、（Ｅ）−２−ヘキセニルヘキサノエート［Ｅ２ＨＨ］とを、各１０ｍｇずつ用い、Ｍ１：Ｅ２ＨＨ＝１：１となるように混合することで、本発明に係る誘引剤（本発明区）を調製した。 By using 10 mg each of myristyl isobutyrate [MI] and (E) -2-hexenylhexanoate [E2HH] and mixing so that M1: E2HH = 1: 1, the present invention is applied. An attractant (invention zone) was prepared.
また、比較のために、イソブチレート［ＭＩ］を単独で１０ｍｇ用いたもの（比較区１）と、（Ｅ）−２−ヘキセニルヘキサノエート［Ｅ２ＨＨ］を単独で１０ｍｇ用いたもの（比較区２）とを調製した。 Further, for comparison, one using 10 mg of isobutyrate [MI] alone (Comparative Group 1) and one using 10 mg of (E) -2-hexenylhexanoate [E2HH] (Comparative Group 2) And were prepared.
上記で得た各区の物質を各々充填したゴムキャップを誘引源とした粘着板を、各区毎に、ダイズほ場内に設置し、３日後に回収して、各区の捕獲個体数をカウントした。 Adhesive plates using the rubber caps filled with the substances obtained in the above sections as the attracting source were placed in the soybean field for each section, collected three days later, and the number of individuals captured in each section was counted.
これを、各区について、４回、同一条件の基に繰り返して行い、統計処理をした。 This was repeated four times for each section under the same conditions, and statistical processing was performed.
その結果は、次のとおりであった。 The results were as follows.
イソブチレート［ＭＩ］による比較区１の個体数が１．３、（Ｅ）−２−ヘキセニルヘキサノエート［Ｅ２ＨＨ］による比較区２の個体数が０．５であったのに対して、本発明区の個体数は７．８であった。 Whereas the number of individuals in comparative group 1 with isobutyrate [MI] was 1.3 and the number of individuals in comparative group 2 with (E) -2-hexenylhexanoate [E2HH] was 0.5, the present invention The number of individuals in the ward was 7.8.
結果を考察すると、本発明区は比較区１と比較区２の個体数の結果を合計した数である１．８の４倍程度の数値を示し、予想外の顕著な効果を示すことが確認できた。
Considering the results, the present invention group shows a numerical value about 4 times 1.8, which is the total number of the results of the number of individuals in the comparison group 1 and the comparison group 2, and confirms that it shows an unexpected remarkable effect. did it.
