Description
本発明は、カシノナガキクイムシ集合フェロモン、該フェロモンを含有するカシノナガキクイムシ誘引剤およびフェロモントラップに関するものである。 The present invention relates to an Aspergillus oryzae gathering pheromone, an Aspergillus oryzae attractant and a pheromone trap containing the pheromone.
カシノナガキクイムシ（Platypus quercivorus (Murayama)）はミズナラ、コナラなどのブナ科樹木樹幹に穿入加害するナガキクイムシ科害虫である。カシノナガキクイムシは植物病原菌を媒介するので、カシノナガキクイムシの集中的な穿入を受けたミズナラなどの樹木はほとんど枯死する。主な枯死被害地は日本海側の地域であるが紀伊半島や大隅半島でも被害が発生している。 Platypus quercivorus (Murayama) is a long-horned beetle pest that invades and damages the trunks of beech trees such as Mizunara and Quercus. Since the oak beetle mediates phytopathogenic fungi, most of the trees, such as mizunara, that have undergone intensive penetration of the oak beetle are dead. The main area that suffers withering is the Sea of Japan side, but damage has also occurred in the Kii and Osumi peninsulas.
しかし、カシノナガキクイムシの穿入に伴うブナ科樹木の枯死被害は、単木的に発生した被害が急速に拡がり、５〜６年後には終息する。その間に個体密度が上昇した
カシノナガキクイムシは次々に周辺林分に分散し，隣接地での枯死原因となって
いる。
However, the damage caused by the death of beech family trees due to the penetration of the Platypus quercivorus spreads rapidly as a single tree and ends after 5 to 6 years. In the meantime, the oak beetle, whose population density has increased, disperses in the surrounding forests one after another, causing death in neighboring areas.
カシノナガキクイムシは一生のほとんどの時間を樹幹孔道内で生活するので、通常の農薬散布によって孔道内のカシノナガキクイムシの成虫や幼虫を駆除することは非常に困難である。ビニールシートを樹幹に巻き付けてカシノナガキクイムシの穿入を予防する方法や、樹木をドリル穿孔して、ドリル穴に農薬を注入して防除する方法が考案されているが、このような単木的な防除法は、急傾斜な被害地では危険を伴い、被害面積も増加している現状では有効な方法とは言い難い。カシノナガキクイムシを効果的に防除するために、その発生を的確に知るための手段や、従来の殺虫剤とは異なる新しいタイプの防除方法が強く望まれている。 As the Platypus quercivorus lives in the trunk canal for most of its lifetime, it is very difficult to control adults and larvae of the Platypus quercivorus in the canal by spraying ordinary pesticides. A method of preventing the penetration of Platypus quercivorus by wrapping a vinyl sheet around a tree trunk and a method of drilling a tree and injecting pesticides into the drill hole have been devised. Such a control method is dangerous in a steeply damaged area, and it is difficult to say that it is effective in the present situation where the damaged area is increasing. In order to effectively control the Platypus quercivorus, means for accurately knowing its occurrence and a new type of control method different from conventional insecticides are strongly desired.
害虫の発生地域の確認ならびに防除時期を予測する方法の一つとしてフェロモントラップを用いる方法が知られているが、カシノナガキクイムシの集合フェロモンおよび誘引物質に関する知見はなく、カシノナガキクイムシの発生調査などに使用できるフェロモントラップは知られていない。 A method using a pheromone trap is known as one of the methods for confirming the occurrence area of pests and predicting the time of control, but there is no knowledge about the collected pheromones and attractants of Platypus quercivorus, investigation of the occurrence of Platypus quercivorus, etc. There are no known pheromone traps available.
本発明が解決しようとする課題は、カシノナガキクイムシの発生状況把握や捕獲などに有効なカシノナガキクイムシ集合フェロモン、カシノナガキクイムシ誘引剤およびフェロモントラップを提供することである。 The problem to be solved by the present invention is to provide an oak beetle gathering pheromone, an oak beetle attractant, and a pheromone trap that are effective for grasping or capturing the occurrence of oak beetle.
上記課題を解決すべく鋭意研究を重ね、カシノナガキクイムシが穿入孔から排出するフラス（木屑と排泄物の混合物）揮発成分を固相微量抽出法による捕集または溶媒抽出による抽出を行い得られた物質をガスクロマトグラフィー質量分析計にて分析した。並行して、カシノナガキクイムシ成虫の触角を用いた室内生物検定を行い活動電位を誘起する物質の特定を行い、ガスクロマトグラフィー質量分析計の結果と併せて化学構造の推定を行ったところ、特定のシクロヘキセン誘導体がカシノナガキクイムシのフェロモンとして有効であることを見出し、本発明を完成するに至った。 Through extensive research to solve the above-mentioned problems, it is possible to collect the volatile components (mixture of wood chips and excrement) volatile components discharged from the borehole by the solid-phase microextraction method or extract by solvent extraction. The material was analyzed with a gas chromatography mass spectrometer. In parallel, we conducted a laboratory bioassay using the antennae of the adult beetle, and identified the substance that induces action potential, and estimated the chemical structure along with the results of the gas chromatography mass spectrometer. The present inventors have found that this cyclohexene derivative is effective as a pheromone of Platypus quercivorus, and has completed the present invention.

以下、実施例により本発明を詳細に説明するが、これにより本発明が限定されることはない。 EXAMPLES Hereinafter, although an Example demonstrates this invention in detail, this invention is not limited by this.
トランス−１−メチル−４−（メチルエチル）−２−シクロヘキセン−１−オール約０．７ｇを脱脂綿に含浸させ、プラスチック容器内に入れてトラップに装着した。比較にはエタノールまたは蒸留水を含浸させた脱脂綿を用いた。各製剤を装着したトラップをミズナラ林内に各製剤当たり２基設置し、誘引されたカシノナガキクイムシ成虫数を調査した。その結果を表１に示す。 Absorbent cotton was impregnated with about 0.7 g of trans-1-methyl-4- (methylethyl) -2-cyclohexen-1-ol, placed in a plastic container, and attached to a trap. For comparison, absorbent cotton impregnated with ethanol or distilled water was used. Two traps equipped with each preparation were installed in each of the oak forests, and the number of attracted adults of Platypus quercivorus was investigated. The results are shown in Table 1.
1) t-MMCO: トランス−１−メチル−４−（メチルエチル）−２−シクロヘキセン−１−オール 1) t-MMCO: trans-1-methyl-4- (methylethyl) -2-cyclohexen-1-ol
表１に示した結果から明らかなように、トランス−１−メチル−４−（メチルエチル）−２−シクロヘキセン−１−オールを含まない脱脂綿を装着したトラップにはほとんど誘引されなかったが、トランス−１−メチル−４−（メチルエチル）−２−シクロヘキセン−１−オールを含浸させた脱脂綿を装着したトラップには発生状況の把握に使用できる誘殺が認められた。 As is apparent from the results shown in Table 1, the trap fitted with absorbent cotton not containing trans-1-methyl-4- (methylethyl) -2-cyclohexen-1-ol was hardly attracted. The trap equipped with the cotton wool impregnated with -1-methyl-4- (methylethyl) -2-cyclohexen-1-ol was found to be a killing that can be used for grasping the occurrence state.
トランス−１−メチル−４−（メチルエチル）−２−シクロヘキセン−１−オールはカシノナガキクイムシの集合フェロモンとして有用であり、カシノナガキクイムシの誘引剤として使用することができ、該誘引剤を用いたフェロモントラップはカシノナガキクイムシの発生調査や捕獲駆除に有用である。 Trans-1-methyl-4- (methylethyl) -2-cyclohexen-1-ol is useful as an aggregation pheromone for the wood beetle, and can be used as an attractant for the wood beetle. The pheromone trap was useful for investigating outbreaks and capturing of Platypus quercivorus.
