Description

【0001】
【発明の属する技術分野】
本発明は、ツヤコガネ成虫に対し、優れた誘引性を示すことを特徴とする誘引剤に関するものである。
【0002】
【従来の技術】
ツヤコガネ(学名:Anomala lucens Ballion)は、幼虫が芝や牧草などの地下部を、成虫が多くの広葉樹の葉を食害する広食性の農業上重要な害虫の一つである。この虫の成虫は比較的広範囲を飛翔するため、また、幼虫は土壌中に生息するため、共に確認が難しく、また薬剤を直接に接触させることが難しいことから薬剤による防除は極めて困難な害虫である。すなわち従来からこの害虫の防除には、幼虫を対象としたカルボスルファン・ダイアジノン・MPP粒剤などの土壌混和処理等が行われているが、これらの薬剤は残効性が低いために、長期間にわたって防除効果を維持することが極めて困難であり、また土壌深くまで薬剤を浸透させなければならないために、散布量も多くなることから環境上の問題も生じやすい。近年、殺虫剤を用いない防除方法のひとつとしてフェロモンや誘引剤の研究がなされるようになり、これらを誘引剤として利用したトラップが害虫の発生調査や捕獲などに利用されている。
【0003】
【発明が解決しようとする課題】
上記トラップで使用する誘引剤の中には、ドウガネブイブイの誘引剤(特許第2545179、特許第3085894)、食葉性コガネムシの誘引剤(特許第2520374)等の特定のコガネムシに対する誘引剤は知られているがツヤコガネに関する誘引剤は未だ創出されておらず、ツヤコガネの誘引剤の創出が強く要望されていた。
【0004】
【課題を解決するための手段】
本発明者らは、上記課題を解決すべく、ツヤコガネに対して誘引活性をもつ物質を広範囲から検索した結果、他のコガネムシの誘引物質として知られている物質の中からツヤコガネに対し極めて誘引効果の高い化合物群を新たに見出した。
【0005】
本発明は以下の構成を有する。
【0006】
(R,Z)−5−(1−オクテニル)オキサシクロペンタン−2−オン、(R,Z)−5−(1−デセニル)オキサシクロペンタン−2−オン、(Z)−3−ヘキセン−1−オールまたは1,2−ジメトキシ−4−(1−プロペニル)ベンゼンから選ばれる少なくとも1種または複数の化合物を含有することを特徴とするツヤコガネ成虫の誘引剤。好ましくは、(R,Z)−5−(1−オクテニル)オキサシクロペンタン−2−オン、(R,Z)−5−(1−デセニル)オキサシクロペンタン−2−オンから選ばれる1種または複数の化合物を含有することを特徴とするツヤコガネ成虫の誘引剤。もしくは、(Z)−3−ヘキセン−1−オール、1,2−ジメトキシ−4−(1−プロペニル)ベンゼンから選ばれる少なくとも1種または複数の化合物を含有することを特徴とするツヤコガネ成虫の誘引剤。さらに好ましくは、(Z)−3−ヘキセン−1−オール、1,2−ジメトキシ−4−(1−プロペニル)ベンゼンから選ばれる1種以上の化合物、(R,Z)−5−(1−オクテニル)オキサシクロペンタン−2−オン及び(R,Z)−5−(1−デセニル)オキサシクロペンタン−2−オンを含有することを特徴とするツヤコガネ成虫の誘引剤。
【0007】
これらの化合物はツヤコガネ以外のコガネムシの誘引剤として容易に入手可能であるか、香料の原料として安価に入手可能であるか、あるいはそれらの試薬から常法によって、容易に合成が可能な物質であり、この発明においては特に限定はされず、何れの手段によって得られたものでも使用することができる。
【0008】
本発明にかかわる誘引剤の調製は、これらの化合物群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利用して行なうことができる。例えば、これらの化合物群をそのまま、あるいはアルコール、エーテル、アセトン、ジクロルメタン、トルエン、ヘキサン、酢酸エチル、ペンタンなどの適当な溶媒で希釈した後に、適当な担体、例えば各種合成高分子体・ゴムなどに吸着させたり、綿や不織布・紙などに含浸させたり、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。
【0009】
これらの誘引剤において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、通常製剤当たり有効成分量を化合物群全体で0.1mg〜20g、好ましくは1mg〜5g含有すればよい。また、有効成分として含有される化合物群の配合比率は、任意の比率で配合することができる。
【0010】

BACKGROUND OF THE INVENTION
The present invention relates to an attractant characterized by exhibiting excellent attractability to adults of the pearl moth.
[0002]
[Prior art]
Tsutsukogane (scientific name: Anomala lucens Ballion) is one of the broadly edible agricultural pests in which larvae damage the underground such as turf and pasture, and adults eat many broadleaf leaves. Because this adult worm flies over a relatively wide area and the larvae live in the soil, it is difficult to confirm both, and it is difficult to control the drug directly. is there. In other words, conventionally, pest control has been carried out with soil mixing treatments such as carbosulfan, diazinon, and MPP granules for larvae. It is extremely difficult to maintain the control effect over a period of time, and since the chemical must be infiltrated deep into the soil, the amount of application is large, and environmental problems are likely to occur. In recent years, pheromone and attractants have been studied as one of the control methods that do not use insecticides, and traps using these as attractants have been used for investigation and capture of pests.
[0003]
[Problems to be solved by the invention]
Among the attractants used in the above traps, there are known attractants for specific scarab beetles, such as the attractant of Doganebuibuy (Patent No. 2545179, Patent No. 3085894), the attractant of leafy beetle (Patent No. 2520374), etc. However, no attractant has been created yet, and there has been a strong demand for the creation of the attractant.
[0004]
[Means for Solving the Problems]
In order to solve the above-mentioned problems, the present inventors searched a wide range of substances having an attracting activity against the pearl moth, and as a result, among the substances known as attractants of other scarab beetles, an extremely attractive effect on the pearl moth. A new compound group with a high value was found.
[0005]
The present invention has the following configuration.
[0006]
(R, Z) -5- (1-octenyl) oxacyclopentan-2-one, (R, Z) -5- (1-decenyl) oxacyclopentan-2-one, (Z) -3-hexene- An attractant for adults of Aspergillus oryzae, which contains at least one compound selected from 1-ol and 1,2-dimethoxy-4- (1-propenyl) benzene. Preferably, one type selected from (R, Z) -5- (1-octenyl) oxacyclopentan-2-one and (R, Z) -5- (1-decenyl) oxacyclopentan-2-one or An attractant for adult moths, comprising a plurality of compounds. Or at least one or more compounds selected from (Z) -3-hexen-1-ol and 1,2-dimethoxy-4- (1-propenyl) benzene. Agent. More preferably, one or more compounds selected from (Z) -3-hexen-1-ol and 1,2-dimethoxy-4- (1-propenyl) benzene, (R, Z) -5- (1- An attractant for an adult moth, characterized in that it contains octenyl) oxacyclopentan-2-one and (R, Z) -5- (1-decenyl) oxacyclopentan-2-one.
[0007]
These compounds are easily available as attractants for chafer beetles other than tsumugi, or can be obtained inexpensively as raw materials for fragrances, or can be easily synthesized from these reagents by conventional methods. The invention is not particularly limited, and those obtained by any means can be used.
[0008]
The attractant according to the present invention can be prepared by using a formulation technique which is usually applied in preparing the attractant using these compound groups. For example, these compound groups are used as they are or after being diluted with an appropriate solvent such as alcohol, ether, acetone, dichloromethane, toluene, hexane, ethyl acetate, pentane, etc., and then applied to an appropriate carrier such as various synthetic polymers and rubbers. It can be adsorbed, impregnated with cotton, non-woven fabric, paper, or the like, and further encapsulated in a molded product of an appropriate polymer material to be formulated.
[0009]
In these attractants, the content of the active ingredient can be determined as appropriate according to the use environment, but the amount of the active ingredient per preparation is usually 0.1 mg to 20 g, preferably 1 mg to 5 g for the entire compound group. Moreover, the compounding ratio of the compound group contained as an active ingredient can be mix | blended by arbitrary ratios.
[0010]
The attractant of the present invention can be used as an attracting source for any form of insect trap such as laver type, sliding-down type, adhesive type, etc., and a piece of wood coated with an insecticide such as diazinon having contact poisoning action, It is also possible to impregnate a resin piece or the like and use it for attracting and killing. The installation location is a location where the violet is generated, for example, a golf course, a lawn such as a park, or an orchard, but is not limited thereto. Next, the present invention will be described more specifically with reference to examples.
[0011]
【Example】
A piece of filter paper was impregnated with 4 mg of (R, Z) -5- (1-octenyl) oxacyclopentan-2-one and 1 mg of (R, Z) -5- (1-decenyl) oxacyclopentan-2-one. Thereafter, it was formulated with a polyethylene film (Formulation 1). A filter paper piece was impregnated with 1500 mg of (Z) -3-hexen-1-ol and 500 mg of 1,2-dimethoxy-4- (1-propenyl) benzene, and then sealed with a polyethylene film to prepare a formulation (Formulation 2). . 4 mg of (R, Z) -5- (1-octenyl) oxacyclopentan-2-one and 1 mg of (R, Z) -5- (1-decenyl) oxacyclopentan-2-one (Z) -3 A filter paper piece was impregnated with 1500 mg of hexen-1-ol and 500 mg of 1,2-dimethoxy-4- (1-propenyl) benzene, and then sealed with a polyethylene film to prepare a formulation (Formulation 3). These preparations were mounted on a dry-type sliding trap (trade name Winds Pack, manufactured by Nippon Tobacco Inc.), and placed on a golf course for 10 days with a trap without an attractant as a control. Three traps were used for each preparation, and the average number of insects was investigated.
[0012]
As a result, as shown in Table 1, it was not attracted to the trap without the attractant as a control, whereas the attractant of the present invention (R, Z) -5- (1-octenyl) An attractant (formulation 1), comprising (O) cyclohexan-2-one, (R, Z) -5- (1-decenyl) oxacyclopentan-2-one as an active ingredient, (Z)- An attractant (formulation 2) comprising 3-hexen-1-ol and 1,2-dimethoxy-4- (1-propenyl) benzene as an active ingredient, (Z) -3-hexene-1- One or more compounds selected from all, 1,2-dimethoxy-4- (1-propenyl) benzene, (R, Z) -5- (1-octenyl) oxacyclopentan-2-one and (R, Z ) -5- (1-decenyl) Kisa attractant agent characterized by containing cyclopentane-2-one (preparation 3) clearly showed the attractant activity against Tsuyakogane adults.
