本発明は、鞘翅目に属する昆虫の誘引剤に関する。特に、本発明は、ホソヒラタムシ科に属するノコギリヒラタムシ、ゴミムシダマシ科に属するコクヌストモドキおよびヒラタコクヌストモドキの誘引剤に関する。 The present invention relates to an attractant for insects belonging to the order Coleoptera. In particular, the present invention relates to an attractant for the sawtoothed flathead beetle, which belongs to the family Polytrichum, and the red flour beetle and flat-headed red flour beetle, which belong to the family Tenebrionidae.
鞘翅目ホソヒラタムシ科に属するノコギリヒラタムシ（学名：Ｏｒｙｚａｅｐｈｉｌｕｓ ｓｕｒｉｎａｍｅｎｓｉｓ）、鞘翅目ゴミムシダマシ科に属するコクヌストモドキ（学名：Ｔｒｉｂｏｌｉｕｍ ｃａｓｔａｎｅｕｍ）とヒラタコクヌストモドキ（学名：Ｔｒｉｂｏｌｉｕｍ ｃｏｎｆｕｓｕｍ）は、日本をはじめ世界各地に生息し、穀粉や加工食品などの貯蔵食品を加害する害虫である。これらの害虫は、単に食糧ロスを生じさせるだけでなく、食品中に混入することでクレームや企業イメージの失墜を引き起こし、食品業界に多大な経済的被害をもたらす。 The sawtooth flour beetle (scientific name: Oryzaephilus surinamensis) belonging to the family Tenebrionidae in the order Coleoptera, the red flour beetle (scientific name: Tribolium castaneum) and the flat-headed flour beetle (scientific name: Tribolium confusum) belonging to the family Tenebrionidae in the order Coleoptera are pests that live in Japan and around the world and damage stored foods such as grain flour and processed foods. These pests not only cause food waste, but also cause complaints and damage to corporate image by contaminating food, causing great economic damage to the food industry.
ノコギリヒラタムシ、コクヌストモドキ、ヒラタコクヌストモドキの被害を予防あるいは防除するためには、総合的害虫管理の観点からモニタリングが重要な役割を担っている。害虫のモニタリングを行う一般的な手段としては、粘着トラップ、光に集まる習性を利用したライトトラップ、誘引物質を利用したトラップなどがあるが、上記３種の虫については、誘引物質を使用したトラップが最も効果的である。 In order to prevent or control damage caused by the sawtooth flathead beetle, red flour beetle, and flat-headed red flour beetle, monitoring plays an important role from the perspective of integrated pest management. Common methods for monitoring pests include sticky traps, light traps that take advantage of the insects' tendency to be attracted to light, and traps that use attractants, but for the three insects mentioned above, traps that use attractants are the most effective.
ノコギリヒラタムシ、コクヌストモドキ、ヒラタコクヌストモドキの誘引物質としては、コクヌストモドキおよびヒラタコクヌストモドキの集合フェロモンである、４，８－ジメチルデカナール（ＳＵＺＵＫＩ， Ｔ．， ＆ ＳＵＧＡＷＡＲＡ， Ｒ． （１９７９）． Ｉｓｏｌａｔｉｏｎ ｏｆ ａｎ ａｇｇｒｅｇａｔｉｏｎ ｐｈｅｒｏｍｏｎｅ ｆｒｏｍ ｔｈｅ ｆｌｏｕｒ ｂｅｅｔｌｅｓ， Ｔｒｉｂｏｌｉｕｍ ｃａｓｔａｎｅｕｍ ａｎｄ Ｔ． ｃｏｎｆｕｓｕｍ （Ｃｏｌｅｏｐｔｅｒａ： Ｔｅｎｅｂｒｉｏｎｉｄａｅ）． Ａｐｐｌｉｅｄ Ｅｎｔｏｍｏｌｏｇｙ ａｎｄ Ｚｏｏｌｏｇｙ， １４（２）， ２２８－２３０．）、ならびにノコギリヒラタムシの集合フェロモンである、３，６－ドデカジエン－１２－オライド、３，６－ドデカジエン－１１－オライド、５，８－テトラデカジエン－１３－オライド（Ｐｉｅｒｃｅ， Ａ． Ｍ．， Ｐｉｅｒｃｅ Ｊｒ， Ｈ． Ｄ．， Ｏｅｈｌｓｃｈｌａｇｅｒ， Ａ． Ｃ．， ＆ Ｂｏｒｄｅｎ， Ｊ． Ｈ． （１９８５）． Ｍａｃｒｏｌｉｄｅ ａｇｇｒｅｇａｔｉｏｎ ｐｈｅｒｏｍｏｎｅｓ ｉｎ Ｏｒｙｚａｅｐｈｉｌｕｓ ｓｕｒｉｎａｍｅｎｓｉｓ ａｎｄ Ｏ． ｍｅｒｃａｔｏｒ （Ｃｏｌｅｏｐｔｅｒａ： Ｃｕｃｕｊｉｄａｅ）． Ｊｏｕｒｎａｌ ｏｆ Ａｇｒｉｃｕｌｔｕｒａｌ ａｎｄ Ｆｏｏｄ Ｃｈｅｍｉｓｔｒｙ， ３３（５）， ８４８－８５２．）のほか、特にノコギリヒラタムシについてはイナゴマメ抽出エキス（Ｏ’Ｄｏｎｎｅｌｌ， Ｍ． Ｊ．， Ｃｈａｍｂｅｒｓ， Ｊ．， ＆ ＭｃＦａｒｌａｎｄ， Ｓ． Ｍ． （１９８３）． Ａｔｔｒａｃｔａｎｃｙ ｔｏ Ｏｒｙｚａｅｐｈｉｌｕｓ ｓｕｒｉｎａｍｅｎｓｉｓ （Ｌ．）， ｓａｗ－ｔｏｏｔｈｅｄ ｇｒａｉｎ ｂｅｅｔｌｅ， ｏｆ ｅｘｔｒａｃｔｓ ｏｆ ｃａｒｏｂｓ， ｓｏｍｅ ｔｒｉｇｌｙｃｅｒｉｄｅｓ， ａｎｄ ｒｅｌａｔｅｄ ｃｏｍｐｏｕｎｄｓ． Ｊｏｕｒｎａｌ ｏｆ Ｃｈｅｍｉｃａｌ Ｅｃｏｌｏｇｙ， ９（３）， ３５７－３７４．）が知られ、実用化されている。 As an attractant for the sawtooth flat beetle, the red flour beetle, and the flat-headed flour beetle, 4,8-dimethyldecanal, which is the aggregation pheromone of the red flour beetle and the flat-headed flour beetle (SUZUKI, T., & SUGAWARA, R. (1979). Isolation of an aggregation pheromone from the flower beetles, Tribolium castaneum and T. confusum (Coleoptera: Tenebrionidae). Applied Entomology and Zoology, 14(2), 228-230. ), and 3,6-dodecadien-12-olide, 3,6-dodecadien-11-olide, and 5,8-tetradecadien-13-olide, which are aggregation pheromones of the sawtooth flathead beetle (Pierce, A. M., Pierce Jr, H. D., Oehlschlager, A. C., & Borden, J. H. (1985). Macrolide aggregation pheromones in Oryzaephilus surinamensis and O. mercator (Coleoptera: Cucurbitaceae). Journal of Agricultural and Food Chemistry, 33(5), 848-852. ), and especially for sawtoothed grain beetles, carob extract (O'Donnell, M. J., Chambers, J., & McFarland, S. M. (1983). Attractancy to Oryzaephilus surinamensis (L.), saw-toothed grain beetle, of extracts of carob, some triglycerides, and related compounds. Journal of Chemical Ecology, 9(3), 357-374.) is known and has been put to practical use.
しかし、これらの誘引物質には一定の効果があるものの、実用上十分とまでは言えず、さらに誘引効果の高い物質の発見が望まれていた。 However, although these attractants have a certain degree of effectiveness, they are not sufficient for practical use, and there is a need to discover substances with even greater attractant effects.
フェロモン以外で昆虫を誘引する物質を探索するには、一般的にその昆虫の餌（食草など）の匂い成分を捕集分析し、検出した物質を網羅的に生物実験に供す手法がとられるが、膨大な数の物質を検査するには労力がかかるうえ、結果として効果的な誘引物質が見つからないことも多い。また、ある物質がある昆虫を誘引することが分かっていても、その物質が他の昆虫に対しても同様の効果を持つかどうかは全く予測できず、昆虫の新規誘引物質を発見することは非常に困難なことである。 To search for substances that attract insects other than pheromones, the usual method is to collect and analyze the odor components of the insect's food (such as food plants) and subject the detected substances to comprehensive biological experiments, but testing a huge number of substances is labor-intensive, and as a result, it is often the case that an effective attractant is not found. Furthermore, even if it is known that a certain substance attracts a certain insect, it is impossible to predict whether the substance will have the same effect on other insects, making it extremely difficult to discover new insect attractants.
本発明は、従来技術の問題点を解決するためになされたものであり、ノコギリヒラタムシ、コクヌストモドキ、ヒラタコクヌストモドキに対して強い誘引効果を有する誘引剤を提供することを目的とする。さらに、その有効成分が安全であり、日常的な使用にも耐えうることも目的とする。 The present invention was made to solve the problems of the prior art, and aims to provide an attractant that has a strong attractant effect on sawtooth flathead beetles, red flour beetles, and flat-headed red flour beetles. It is also an object of the present invention to provide an active ingredient that is safe and can withstand daily use.
本発明者は、上記課題を解決すべく、ノコギリヒラタムシ、コクヌストモドキ、ヒラタコクヌストモドキに対して誘引効果を持つ物質について鋭意検討した。その結果、以下に示す誘引剤を見出した。 In order to solve the above problems, the present inventors have conducted extensive research into substances that have an attractive effect on the sawtooth flathead beetle, the red flour beetle, and the flat-headed red flour beetle. As a result, they have discovered the attractants shown below.
すなわち、本発明は、第一に、ソトロンとマルトールからなる群より選択される少なくとも一つを含むことを特徴とする、ノコギリヒラタムシの誘引剤である。
第二に、ソトロンを含むことを特徴とする、鞘翅目ゴミムシダマシ科に属する昆虫の誘引剤である。
第三に、鞘翅目ゴミムシダマシ科に属する昆虫が、コクヌストモドキ又はヒラタコクヌストモドキであることを特徴とする、上記第二に記載の誘引剤である。
That is, firstly, the present invention relates to an attractant for sawtooth flathead beetles, which is characterized by containing at least one selected from the group consisting of sotolon and maltol.
The second is an attractant for insects belonging to the Tenebrionidae family of the Coleoptera order, which is characterized by containing sotolon.
Thirdly, there is provided the attractant according to the above-mentioned second aspect, characterized in that the insect belonging to the family Tenebrionidae of the order Coleoptera is Tribolium castaneum or Tribolium confusum.
ソトロンは、鞘翅目のホソヒラタムシ科に属するノコギリヒラタムシ、およびゴミムシダマシ科に属する昆虫、特に、コクヌストモドキまたはヒラタコクヌストモドキに対する誘引効果を有する。さらに、マルトールは、鞘翅目の中でもノコギリヒラタムシに対する誘引効果が顕著である。 Sotolon has an attractive effect on the sawtooth flathead beetle, which belongs to the family Polytrichum communes, and insects belonging to the family Tenebrionidae, particularly the red flour beetle and the flat-headed red flour beetle. Furthermore, maltol has a remarkable attractive effect on the sawtooth flathead beetle, which belongs to the family Coleoptera.
本発明に係る誘引剤の調製は、これらの物質を用いて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用いて行うことができる。例えば、これらの化合物をそのまま、あるいはエーテル、アセトン、アルコール、ヘキサン、ペンタン、ジクロロメタン、トリグリセライド等の適当な溶媒で希釈した後、適当な担体、例えば、各種合成高分子体、ゴム等に吸着させたり、綿や不織布、紙、繊維等に含浸させたり、さらに適当な高分子材料の成型物に封入して製剤化することができる。 The attractant of the present invention can be prepared using these substances by using formulation techniques that are normally applied when preparing attractants. For example, these compounds can be used as is or diluted with a suitable solvent such as ether, acetone, alcohol, hexane, pentane, dichloromethane, triglyceride, etc., and then adsorbed onto a suitable carrier such as various synthetic polymers or rubber, or impregnated into cotton, nonwoven fabric, paper, fiber, etc., or further encapsulated in a molded product made of a suitable polymer material to form a formulation.
誘引剤における有効成分の含有量は使用環境に応じて適宜定めることができるが、本発明においては、通常製剤あたり有効成分量を０．００１ｍｇ～１ｇ添加することができ、好ましくは０．０１ｍｇ～１０ｍｇの範囲である。 The amount of active ingredient in the attractant can be determined appropriately depending on the environment in which it is used, but in the present invention, the amount of active ingredient can usually be added per formulation in an amount of 0.001 mg to 1 g, and preferably in the range of 0.01 mg to 10 mg.
本発明の誘引剤は水盤式、滑落式、粘着式等の任意の形態の捕虫器の誘引源として利用することができる。また、接触毒作用を有するダイアジノン等の殺虫剤を塗布した木片、樹脂片等に含浸させ、誘引捕殺に利用することも可能である。 The attractant of the present invention can be used as an attraction source for any type of insect trap, such as a water pan type, a sliding type, or a sticky type. It can also be used to attract and kill insects by impregnating pieces of wood or resin coated with an insecticide such as diazinon, which has a contact poisoning effect.
本発明によれば、ソトロンとマルトールのうち少なくとも片方、または両方を任意の比率で混合したものを含む誘引剤により、従来の誘引剤と比べ強力に、ノコギリヒラタムシ、コクヌストモドキ、またはヒラタコクヌストモドキといった害虫を誘引することができる。また、ソトロンやマルトールは食品香料のため安全であり、食品工場等での日常的な使用にも耐えうるものである。 According to the present invention, an attractant containing at least one of sotolon and maltol, or a mixture of both in any ratio, can attract pests such as sawtooth flathead beetles, red flour beetles, and flat-headed red flour beetles more strongly than conventional attractants. In addition, sotolon and maltol are safe because they are food flavorings, and can withstand daily use in food factories, etc.
以下に実施例を用いて本発明を詳細に説明するが、本発明は以下の実施例に限定されるものではない。また、以下の実施例で使用した誘引剤は、全て不織布に誘引物質を規定量含浸させ、その後ポリエチレンフィルムで覆って製剤化したものである。 The present invention will be described in detail below using examples, but the present invention is not limited to the following examples. In addition, all of the attractants used in the following examples were formulated by impregnating a specified amount of attractant into nonwoven fabric and then covering it with a polyethylene film.
ノコギリヒラタムシの誘引剤として、以下の誘引物質Ａ、Ｂ、Ｃ、Ｄ、Ｅ、Ｆ、Ｇを上記の手法に則りそれぞれ製剤化したものを用いた。
Ａ：５，８－テトラデカジエン－１３－オライド（ノコギリヒラタムシフェロモン）１ｍｇ
Ｂ：イナゴマメ抽出エキスをエタノールで精製したもの５ｍｇ
Ｃ：ソトロン１ｍｇ
Ｄ：ソトロン０．１ｍｇ
Ｅ：マルトール１ｍｇ
Ｆ：マルトール０．１ｍｇ
Ｇ：ソトロン１ｍｇ＋マルトール１ｍｇ
As attractants for sawtooth flathead beetles, the following attractants A, B, C, D, E, F, and G were formulated in accordance with the above-mentioned method and used.
A: 5,8-tetradecadiene-13-olide (sawtooth beetle pheromone) 1 mg
B: Carob extract purified with ethanol 5 mg
C: Sotolone 1 mg
D: Sotolone 0.1 mg
E: Maltol 1mg
F: Maltol 0.1 mg
G: Sotolone 1mg + Maltol 1mg
これらの誘引剤を、粘着紙を使用した害虫捕獲器（「トリオス」、富士フレーバー株式会社製）に装填し、何も誘引剤を入れない同一の害虫捕獲器とともに、互いに３０ｃｍの距離を置いて一辺５０ｃｍの塩化ビニル製ケージの底面に設置した。このケージ内部に、ノコギリヒラタムシ１００匹を放飼し２４時間自由に活動させた。 These attractants were loaded into pest traps using sticky paper ("Trios", Fuji Flavor Co., Ltd.) and placed on the bottom of a polyvinyl chloride cage measuring 50 cm on each side, 30 cm apart from each other, along with identical pest traps containing no attractants. 100 sawtooth flathead beetles were released into the cage and allowed to move freely for 24 hours.
２４時間後、各捕獲器の捕虫数を計測しＥＰＩ：（誘引剤入りトラップの捕虫数－何も入れないトラップの捕虫数）／（誘引剤入りトラップの捕虫数＋何も入れないトラップの捕虫数）を算出した。複数回行ったＥＰＩの平均値は、Ａ：０．１１、Ｂ：０．１３、Ｃ：０．３９、Ｄ：０．２４、Ｅ：０．３４、Ｆ：０．４８、Ｇ：０．３１であった。 After 24 hours, the number of insects caught in each trap was counted and the EPI was calculated: (number of insects caught in traps with attractants - number of insects caught in traps with nothing) / (number of insects caught in traps with attractants + number of insects caught in traps with nothing). The average EPI values from multiple runs were A: 0.11, B: 0.13, C: 0.39, D: 0.24, E: 0.34, F: 0.48, G: 0.31.
この結果により、ソトロンやマルトールは既知のフェロモンやイナゴマメ抽出エキスに比べ、格段に高い誘引力を持つことが示された。 These results show that sotolon and maltol have a much stronger attractant power than known pheromones and carob extracts.
コクヌストモドキの誘引剤として、以下の誘引物質Ｈ、Ｉを上記の手法に則りそれぞれ製剤化したものを用いた。
Ｈ：４，８－ジメチルデカナール（コクヌストモドキフェロモン）１ｍｇ
Ｉ：ソトロン０．１ｍｇ
As attractants for the red flour beetle, the following attractants H and I were formulated in accordance with the above-mentioned method and used.
H: 4,8-dimethyldecanal (red flour beetle pheromone) 1 mg
I: Sotolone 0.1 mg
これらの誘引剤を、粘着紙を使用した害虫捕獲器（「トリオス」、富士フレーバー株式会社製）に装填し、何も誘引剤を入れない同一の害虫捕獲器とともに、互いに５０ｃｍの距離を置いて一辺１００ｃｍの塩化ビニル製ケージの底面に設置した。このケージ内部に、コクヌストモドキ１００匹を放飼し、２４時間自由に活動させた。 These attractants were loaded into pest traps using sticky paper ("Trios", Fuji Flavor Co., Ltd.) and placed on the bottom of a 100 cm x 100 cm vinyl chloride cage, 50 cm apart from the other pest traps containing no attractants. 100 red flour beetles were released into the cage and allowed to move freely for 24 hours.
２４時間後、各捕獲器の捕虫数を計測し、実施例１と同様にＥＰＩを算出した。複数回行ったＥＰＩの平均値は、Ｈ：０．１９、Ｉ：０．２５であった。 After 24 hours, the number of insects caught in each trap was counted, and the EPI was calculated in the same manner as in Example 1. The average EPI values obtained by multiple runs were H: 0.19 and I: 0.25.
この結果により、ソトロンは既知のフェロモンに比べ、高い誘引力を持つことが示された。 These results indicate that sotolon has a stronger attractant power than known pheromones.
ヒラタコクヌストモドキの誘引剤として、以下の誘引物質Ｊ、Ｋを上記の手法に則りそれぞれ製剤化したものを用いた。
Ｊ：４，８－ジメチルデカナール（ヒラタコクヌストモドキフェロモン）１ｍｇ
Ｋ：ソトロン１ｍｇ
As attractants for the flat-headed flour beetle, the following attractants J and K were formulated according to the above-mentioned method and used.
J: 4,8-dimethyldecanal (Flour beetle pheromone) 1 mg
K: Sotolone 1 mg
これらの誘引剤を、粘着紙を使用した害虫捕獲器（「トリオス」、富士フレーバー株式会社製）に装填し、何も誘引剤を入れない同一の害虫捕獲器とともに、互いに５０ｃｍの距離を置いて一辺１００ｃｍの塩化ビニル製ケージの底面に設置した。このケージ内部に、ヒラタコクヌストモドキ８０匹を放飼し、２４時間自由に活動させた。 These attractants were loaded into pest traps using sticky paper ("Trios", Fuji Flavor Co., Ltd.) and placed on the bottom of a 100 cm x 100 cm vinyl chloride cage, 50 cm apart from the other pest traps containing no attractants. Eighty flat-headed flour beetles were released into the cage and allowed to move freely for 24 hours.
２４時間後、各捕獲器の捕虫数を計測し、実施例１と同様にＥＰＩを算出した。複数回行ったＥＰＩの平均値は、Ｊ：－０．０４５、Ｋ：０．１３であった。 After 24 hours, the number of insects caught in each trap was counted, and the EPI was calculated in the same manner as in Example 1. The average EPI values obtained multiple times were J: -0.045 and K: 0.13.
この結果により、ソトロンは既知のフェロモンに比べ、高い誘引力を持つことが示された。
These results demonstrated that sotolone has a stronger attractive power than known pheromones.
