Description

Translated fromJapanese

本発明は、飛翔害虫誘引剤に関し、更に詳しくは、ハエ類、コバエ類、蚊類等の飛翔害虫を捕獲するための捕獲器等に利用される飛翔害虫誘引剤に関する。 The present invention relates to a flying pest attractant, and more particularly to a flying pest attractant used as a trap for catching flying pests such as flies, flies and mosquitoes.

従来、ゴキブリ、ハエ、アリ等の害虫を防除するために、毒餌剤等が使用されており、該毒餌剤は防除効果を高めるために誘引殺虫剤として使用されている。誘引殺虫剤は、害虫が生息、活動する範囲に予め設置され、害虫を誘引して、殺虫剤を摂取させることや捕獲器で捕獲することで害虫を防除する。 Conventionally, poison bait agents and the like have been used to control pests such as cockroaches, flies and ants, and the poison bait agents have been used as attracting insecticides in order to enhance the control effect. The attracting insecticide is installed in advance in the area where the pest inhabits and acts, and the pest is controlled by attracting the pest and ingesting the insecticide or catching it with a trap.

ハエ等の飛翔害虫防除に用いられる捕獲器として、例えば、害虫誘引剤を内部に収容した捕獲器が知られている(例えば、特許文献1参照)。このような捕獲器は使用時に、前記容器に設けられた開口から害虫誘引剤を周囲雰囲気中に放出する。すると、害虫誘引剤によって誘引された害虫が、前記開口を介して前記容器内に進入するとともに前記害虫誘引剤にひたって溺死したり、併用されている殺虫剤によって殺虫されたりする。 As a trap used for controlling flying pests such as flies, for example, a trap containing a pest attractant inside is known (see, for example, Patent Document 1). During use, such a trap releases the pest attractant into the ambient atmosphere through an opening provided in the container. Then, the pests attracted by the pest attractant enter the container through the opening and are drowned by the pest attractant, or are killed by the pesticide used in combination.

従来の誘引殺虫剤や害虫誘引剤は、任意の場所に長時間設置して使用されるものであるため、時間の経過につれて有効成分や誘引剤等が変質、乾燥し、十分な防除効果が得られない場合があった。 Since conventional attractant insecticides and pest attractants are used by installing them in any place for a long time, the active ingredients and attractants deteriorate and dry over time, and a sufficient control effect is obtained. In some cases it was not possible.

そこで、このような課題を解決するために、例えば、薬剤組成物に誘引成分の蒸散抑制物質としてグリセリン等の脂肪族多価アルコールを加えること(例えば、特許文献2参照)、また、殺虫用組成物中の基材として微結晶化ワックスやペトロラタムを用いること(例えば、特許文献3参照)が提案されている。 Therefore, in order to solve such a problem, for example, an aliphatic polyhydric alcohol such as glycerin is added to the drug composition as an evaporative inhibitor of the attracting component (see, for example, Patent Document 2), and an insecticidal composition. It has been proposed to use microcrystallized wax or petrolatum as a base material in a substance (see, for example, Patent Document 3).

しかしながら従来の飛翔害虫誘引剤は、時間の経過につれて誘引効果が低下することを十分に防ぐことができず、改善が求められていた。
したがって本発明の課題は、飛翔害虫を捕獲するための捕獲器等に利用される飛翔害虫誘引剤であって、飛翔害虫の良好な誘引効果が長期間にわたり持続可能な飛翔害虫誘引剤を提供することにある。
However, the conventional flying pest attractant cannot sufficiently prevent the attracting effect from decreasing with the passage of time, and improvement has been required.
Therefore, an object of the present invention is to provide a flying pest attractant used for a trap or the like for catching flying pests, and the flying pest attractant having a good attracting effect of flying pests is sustainable for a long period of time. There is.

Can be done. Further, when the average particle size of the gel particles is 25 mm or less, the surface area of the entire flying pest attractant contained in the trap becomes large, so that the attracting component is easily volatilized and the attracting efficiency of the flying pests can be improved. it can.
The average particle diameter of the gel particles means, for example, the diameter if it is spherical, and the length in the longitudinal direction if it is rod-shaped or rectangular (cubic).

ゲル粒の形状は特に限定されないが、ゲル粒同士の間に飛翔害虫が進入可能な空隙を形成するという観点からは、球状、楕円球状、略立方体状、略直方体状、略円柱状等であることが好ましい。なお、上記したように、ゲル粒の形状は、吸液性材料の形状をそのまま採用してもよいし、液体誘引成分を含浸させて膨潤したゲル粒を所望の形状に粉砕してもよい。 The shape of the gel grains is not particularly limited, but from the viewpoint of forming voids between the gel grains in which flying pests can enter, the gel grains are spherical, elliptical spherical, substantially cubic, substantially rectangular parallelepiped, substantially columnar, or the like. Is preferable. As described above, the shape of the gel granules may be the same as that of the liquid absorbing material, or the gel granules swelled by impregnating with the liquid attracting component may be pulverized into a desired shape.

(Solid attractant component)
The solid attractant component used in the present invention may be one that exists on the surface of the gel granules in a solid state when the flying pest attractant of the present invention is used.
Such solid attractants include animal-derived substances such as sardines, krill, fish meal, beef, crickets, butterflies, moths, flies, fish, livestock, and eggs; onions, peanuts, pumpkin seeds, wheat bran, and wheat flour. , Plant-derived substances such as corn, broad beans, soybeans, sugar, brown sugar; substances derived from microorganisms such as yeast, and the like. These may be used alone or in combination of two or more. Among them, it is preferable to use onion powder, onion, krill, and fishmeal, and specifically, it is preferable to use at least one of powdered onion powder, onion powder, krill powder, and fishmeal.

固形誘引成分は、上記したように粉末の形状であることが好ましく、その平均粒子径は、例えば、0.1〜1000μmであることが好ましく、10〜300μmがより好ましい。固形誘引成分の平均粒子径が0.1μm以上であると、固形誘引成分をゲル粒の表面に均一に付着させることができ、1000μm以下であると、固形誘引成分をゲル粒の表面から落下することなく付着させることができる。なお、固形誘引成分の平均粒子径は、例えばふるい分け法等の常法により算出することができる。 The solid attracting component is preferably in the form of a powder as described above, and the average particle size thereof is preferably, for example, 0.1 to 1000 μm, more preferably 10 to 300 μm.

As shown in FIG. 2, the flyingpest attractant 14 is in a state in which the solid attractingcomponent 2 adheres to the surface of the gel grain 1 and the gel grain 1 is covered with the solid attractingcomponent 2. It is presumed that this configuration improves the sustainability of the attracting effect due to the gel-retaining action of the attached solid attracting component and the concentration adjusting action of the volatilizing attracting component.

固形誘引成分をゲル粒の表面に付着させる方法としては、ブレンダー等でゲル粒と粉体状の固形誘引成分を混合させて付着させる方法、ゲル粒に粉体状の固形誘引成分を噴霧して付着させる方法、ゲル粒に固形誘引成分を振り掛ける方法等を挙げることができる。また、液体誘引成分を含有した水溶液に固形誘引成分を分散させた混合液を作製し、この混合液に合成ポリマー系吸水性樹脂を浸漬させることで、合成ポリマー系吸水性樹脂は液体誘引成分を含有した水溶液を吸液し膨潤してゲル粒を形成すると共に、ゲル粒の表面には固形誘引成分が付着するので、ゲル粒の作製と固形誘引成分の付着を一度に行うことができる。 As a method of adhering the solid attractant component to the surface of the gel granules, a method of mixing and adhering the gel granules and the powdery solid attractant component with a blender or the like, or spraying the powdery solid attractant component on the gel granules. Examples thereof include a method of adhering and a method of sprinkling a solid attracting component on gel particles. Further, by preparing a mixed solution in which the solid attracting component is dispersed in an aqueous solution containing a liquid attracting component and immersing the synthetic polymer-based water-absorbent resin in the mixed solution, the synthetic polymer-based water-absorbent resin can be used as a liquid-attracting component. The contained aqueous solution is absorbed and swollen to form gel grains, and the solid attracting component adheres to the surface of the gel grains. Therefore, the gel grains can be prepared and the solid attracting component can be attached at the same time.

固形誘引成分は、本発明の効果が向上するという観点から、ゲル粒の表面積に対し、5〜80%の割合で付着していることが好ましく、20〜50%の割合が更に好ましい。 From the viewpoint of improving the effect of the present invention, the solid attracting component is preferably attached at a ratio of 5 to 80% with respect to the surface area of the gel grains, and more preferably at a ratio of 20 to 50%.

また、本発明の飛翔害虫誘引剤において、吸液性材料100質量部に対して、固形誘引成分を1〜500質量部含むことが好ましく、より好ましくは30〜100質量部である。固形誘引成分とゲル粒の含有量が前記範囲であると、付着した固形誘引成分によるゲル保形性作用および揮発する誘引成分の濃度調節作用により、効果的に誘引できる。 Further, the flying pest attractant of the present invention preferably contains 1 to 500 parts by mass of a solid attracting component with respect to 100 parts by mass of the liquid absorbing material, and more preferably 30 to 100 parts by mass. When the contents of the solid attracting component and the gel granules are in the above range, the solid attracting component can be effectively attracted by the gel shape-retaining action and the concentration adjusting action of the volatilizing attracting component.

本発明において、固形誘引成分の平均粒子径とゲル粒の平均粒子径の比は、0.2:100〜40:100であることが好ましく、0.5:100〜10:100であることがより好ましい。このような平均粒子径の比を有することにより、ゲル粒の表面に固形誘引成分が良好に付着し、ゲル粒の周囲に固形誘引成分を保持できるため、効果的に捕獲できるという効果を奏することができる。 In the present invention, the ratio of the average particle size of the solid attracting component to the average particle size of the gel particles is preferably 0.2: 100 to 40: 100, and preferably 0.5: 100 to 10: 100. More preferred. By having such an average particle size ratio, the solid attractant component adheres well to the surface of the gel grain, and the solid attractant component can be retained around the gel grain, so that the effect of effectively capturing the gel grain can be achieved. Can be done.

また、本発明の飛翔害虫誘引剤は、誘引性に影響を及ぼさない範囲で、各種殺虫剤を含有させて殺虫効果を付与することも可能である。飛翔害虫誘引剤が更に殺虫剤を含有することにより、飛翔害虫の殺虫効果を、良好な持続性でもって維持することが可能となる。 In addition, the flying pest attractant of the present invention can also contain various insecticides to impart an insecticidal effect as long as it does not affect the attractiveness.

In addition, for insects other than Diptera, such as aphids of the order Hemiptera (Hemiptera), planthoppers, scale insects, stink bugs, leafhoppers, and fruit suckers of the order Lepidoptera (Lepidoptera). Can also be used.

本発明の飛翔害虫誘引剤の使用に際しては、従来の害虫捕獲器を利用することができ、例えば、国際公開WO2008/062613号に開示されたような、開口部を有する容器に、本発明の飛翔害虫誘引剤を層状に収容した害虫捕獲器を利用できる。
具体的には、図1に示すように、害虫捕獲器10は、蓋体12と本体13とを備えた容器11と、本発明の飛翔害虫誘引剤14(図2参照)と、から構成される。蓋体12には、突出部15と外縁部との間に5個の大形側開口部16が円周方向に等間隔で形成されているとともに、突出部15の周囲に5個の小形側開口部17が等間隔で形成されている。蓋体12はドーム形状を好む飛翔害虫の習性を利用して、蓋体12に飛翔害虫を集めて、更に開口部16,17から内部に進入することを促すことができる。なお、蓋体12の開口部の数や大きさは、飛翔害虫が容器11内に進入可能な限り特に限定されるものではない。容器11(本体13)内には、図2に示したように、多数の飛翔害虫誘引剤14が層状に収容されている。飛翔害虫誘引剤14間には、飛翔害虫が容器11の深部(本体13の底部)へ進入可能な空隙が設けられている。また、容器11の外面は赤や茶やオレンジの暖色系に着色されることで、また、シボ加工を設けることで誘引性をより高めることができるため好ましい。
In using the flying pest attractant of the present invention, a conventional pest trap can be used, for example, in a container having an opening as disclosed in International Publication WO2008 / 062613, the flying pest of the present invention can be used. A pest trap can be used that contains a layer of pest attractant.
Specifically, as shown in FIG. 1, thepest trap 10 is composed of acontainer 11 having alid 12 and amain body 13 and a flying pest attractant 14 (see FIG. 2) of the present invention. To. In thelid 12, fivelarge side openings 16 are formed between theprotrusion 15 and the outer edge at equal intervals in the circumferential direction, and five small sides are formed around theprotrusion 15. Theopenings 17 are formed at equal intervals. Thelid body 12 can utilize the habit of flying pests that prefer a dome shape to collect flying pests on thelid body 12 and further encourage them to enter the inside through theopenings 16 and 17. The number and size of the openings of thelid 12 are not particularly limited as long as the flying pests can enter thecontainer 11. As shown in FIG. 2, a large number of flyingpest attractants 14 are housed in a layer in the container 11 (main body 13). A gap is provided between the flyingpest attractants 14 so that the flying pests can enter the deep part of the container 11 (the bottom of the main body 13). Further, it is preferable that the outer surface of thecontainer 11 is colored in warm colors such as red, brown, and orange, and that the texture can be provided to further enhance the attractiveness.

更に、本体13の形状は飛翔害虫誘引剤14を収容できる限り特に限定されるものではない。例えば、本体13の底部を突起状にすれば、害虫捕獲器を土壌に突き刺して設置することができ、農業用や園芸用として有用である。また、設置箇所に応じて粘着テープ、粘着剤等を付し、壁面、床面、柱等に固定可能としてもよい。
図2に示すように、本体13の底部の中央部に嵩上げ部22が突出して設けられると、当該嵩上げ部22は本体13内に収容される飛翔害虫誘引剤14の容量を必要以上多くしないようにして飛翔害虫誘引剤14を無駄に使うことを防止する機能を有する。なお、嵩上げ部22が飛翔害虫誘引剤14の表面より上方に向けて突出する場合には、飛翔害虫に止まり木を与える機能を更に有することとなるので更に好ましい。
Further, the shape of themain body 13 is not particularly limited as long as it can accommodate the flyingpest attractant 14. For example, if the bottom of themain body 13 has a protruding shape, the pest trap can be pierced into the soil and installed, which is useful for agriculture and horticulture. Further, depending on the installation location, an adhesive tape, an adhesive or the like may be attached so that the adhesive can be fixed to a wall surface, a floor surface, a pillar or the like.
As shown in FIG. 2, when the raisingportion 22 is provided so as to project from the central portion of the bottom of themain body 13, the raisingportion 22 does not increase the capacity of the flyingpest attractant 14 housed in themain body 13 more than necessary. It has a function of preventing the flyingpest attractant 14 from being wasted. In addition, when the raisedportion 22 protrudes upward from the surface of the flyingpest attractant 14, it is more preferable because it further has a function of giving a perch to the flying pest.

害虫捕獲器10の開口部16,17から容器内に進入してきた飛翔害虫は、飛翔害虫誘引剤14によって誘引されていき、飛翔害虫誘引剤14に接触したところで羽等が濡れて動けなくなって死んだり、殺虫剤を併用した場合はその作用も加わって死に至る。これにより、飛翔害虫を効果的に捕獲及び/又は防除することができる。 The flying pests that have entered the container through theopenings 16 and 17 of thepest trap 10 are attracted by the flyingpest attractant 14, and when they come into contact with the flyingpest attractant 14, their wings and the like get wet and become immobile and die. However, when pesticides are used in combination, the action is added and death occurs. As a result, flying pests can be effectively captured and / or controlled.

また、本発明の飛翔害虫誘引剤は毒餌剤としても使用できる。飛翔害虫が集まる室内又は室外に設置することにより、効果的に飛翔害虫を防除できる。 The flying pest attractant of the present invention can also be used as a poison bait. By installing it indoors or outdoors where flying pests gather, it is possible to effectively control flying pests.
