Description

本発明は、スモモ果実の重要害虫であるスモモヒメシンクイ(学名:Grapholita dimorpha)の性フェロモン組成物、性誘引剤、交信撹乱剤及び交信撹乱方法に関するものである。   The present invention relates to a sex pheromone composition, a sex attractant, a communication disrupter, and a communication disruption method for the plum fruit moth (Scientific name: Grapholita dimorpha), which is an important pest of plum fruit.

スモモヒメシンクイは、スモモの果実を加害するスモモの重要害虫である。果実表面に産みつけられた卵は2〜3日後に孵化し、その直後、果実内に侵入する。終令幼虫まで果実中で生息するため、殺虫剤が害虫に届く期間、いわゆる防除適期は産卵から数日間と非常短いため、殺虫剤による防除が極めて困難である。   The plum tree is a key insect pest of plums that harms the fruits of plums. Eggs laid on the fruit surface hatch after 2-3 days and immediately enter the fruit. Since the end larvae live in the fruit, the period during which the insecticide reaches the pests, the so-called control period, is as short as several days from egg laying, so it is very difficult to control with insecticides.

近年、多くの蛾類で性フェロモンの化学構造が明らかにされ、これを化学合成した合成性フェロモンを用いて害虫の発生消長調査が効率的に行われるようになった。性フェロモンとは、一般に、雌成虫が分泌する化学物質で同種の雄成虫に対して種特異的に誘引作用を示す。このような性フェロモンの化学構造を明らかにして、いわゆる性誘引物質として用いることにより、効率的な発生消長を調査することが可能となる。さらに、この性誘引物質を用いて、雌雄の交尾行動を撹乱する、いわゆる交信撹乱法により、成虫期を対象とした害虫の防除を行うことも可能である(特許文献1〜4)。   In recent years, the chemical structure of sex pheromones has been clarified in many mosses, and the occurrence and development of pests have been efficiently investigated using synthetic pheromones that have been chemically synthesized. A sex pheromone is a chemical substance secreted by a female adult and generally has a species-specific attracting action on the same male adult. By clarifying the chemical structure of such a sex pheromone and using it as a so-called sex attractant, it is possible to investigate the efficient generation and development. Furthermore, it is also possible to control pests targeting the adult stage by the so-called communication disruption method using this sex attractant to disrupt the mating behavior of males and females (Patent Documents 1 to 4).

本発明の目的は、発生消長や交信撹乱に利用が期待されるスモモヒメシンクイの性フェロモンの化学構造を明らかにし、本種の性誘引剤、交信撹乱剤及び交信撹乱方法を提供しようとするものである。   It is an object of the present invention to clarify the chemical structure of the sex pheromone of Prunus japonica, which is expected to be used for developmental fluctuation and communication disruption, and to provide this kind of sex attractant, communication disruptor, and communication disruption method Is.

本発明者らは、上記課題の解決のため、スモモヒメシンクイの性フェロモンの単離同定に関する研究を進めた。
実際には、本種の交尾時間帯に未交尾雌成虫の性フェロモン腺を顕微鏡下で切り取り、個体ごとに50マイクロリットルのn−ヘキサンで抽出した。この抽出液を濃縮し、0.5雌等量をガスクロマトグラフィー質量分析により分析した。その結果、全ての個体から、特徴的な2つのピークがほぼ15:85という一定の比率で観察された。これらのピークは、そのマススペクトラムから、いずれも炭素数12、モノエンの酢酸エステルと推定された。そこで、化学合成した(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートをガスクロマトグラフィー質量分析により分析したところ、リテンションタイムとマススペクトルが完全に一致し、スモモヒメシンクイの主要な性フェロモン成分は、(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートの15:85混合物であることが明らかになった。
In order to solve the above-mentioned problems, the present inventors proceeded with research on the isolation and identification of the sex pheromone of the spruce budworm.
Actually, the sex pheromone glands of unmatured female adults were cut out under a microscope during the mating time of this species, and each individual was extracted with 50 microliters of n-hexane. The extract was concentrated and 0.5 female equivalent was analyzed by gas chromatography mass spectrometry. As a result, two characteristic peaks were observed from all individuals at a constant ratio of approximately 15:85. These peaks were presumed to be monoene acetates with 12 carbon atoms from the mass spectrum. Therefore, when chemically synthesized (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate were analyzed by gas chromatography mass spectrometry, the retention time and mass spectrum were completely in agreement. It was revealed that the main sex pheromone component of Prunus japonica was a 15:85 mixture of (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate.

更に、本発明者らは野外誘引試験を実施したところ、性誘引物質としての活性は、(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートの混合比が15:85において最も高くなるが、(5:95)〜(50:50)の混合比にも誘引されることを見出し、さらに、この混合物を高濃度で圃場に漂わせると交信撹乱現象が起こることを見出し、本発明の完成に至った。   Furthermore, when the present inventors conducted a field attraction test, the activity as a sex attractant was determined by the mixing ratio of (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate. It becomes the highest at 15:85, but it is found that it is also attracted by the mixing ratio of (5:95) to (50:50). Further, when this mixture is floated in the field at a high concentration, a communication disturbance phenomenon occurs. As a result, the present invention has been completed.

本発明は、(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートを(5:95)〜(50:50)の重量割合で含んでなるスモモヒメシンクイの性フェロモン組成物、スモモヒメシンクイの性誘引剤、スモモヒメシンクイの交信撹乱剤を提供する。また、スモモヒメシンクイの交信撹乱剤を用いるスモモヒメシンクイの交信撹乱方法を提供する。   The present invention relates to a plum tree comprising (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate in a weight ratio of (5:95) to (50:50). A sex pheromone composition, a sex attractant for Prunus persimmon, and a communication disruptor for Prunus persimmon. Also provided is a method for disrupting the communication of the peach moth.

本発明によれば、スモモヒメシンクイの雄成虫を特異的に誘引し、発生状況を知るのに有効な誘引剤を得ることができ、さらに、交信撹乱への応用により、直接的に本種を防除することが可能となる。   According to the present invention, it is possible to obtain an attractant effective for specifically attracting male adults of the spruce budworm, to know the occurrence state, and further, by directly applying it to communication disturbance, Can be controlled.

本発明の性フェロモン組成物、誘引剤や交信撹乱剤に含まれる(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートは、公知の方法により製造することができる。また、(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートとの混合重量比率は、(5:95)〜(50:50)、特に(5:95)〜(20:80)であることを要する。この範囲を外れると、スモモヒメシンクイの誘引及び交信撹乱の効果が極端に低下する。   (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate contained in the sex pheromone composition, attractant and communication disrupter of the present invention can be produced by known methods. it can. The mixing weight ratio of (E) -8-dodecenyl acetate to (Z) -8-dodecenyl acetate is (5:95) to (50:50), particularly (5:95). It is necessary to be (20:80). If it is out of this range, the effect of attracting the plum and the disruption of communication will be extremely reduced.

誘引剤は、雄成虫を積極的におびき寄せるため、虫が利用している性フェロモンに、その組成や量を近づけ製剤化したものである。害虫の発生時期や発生量を把握する目的で利用される。
一方、交信撹乱剤は、雌雄の性フェロモン交信を撹乱させるために、虫が利用している性フェロモンの千倍以上の高濃度で、合成性フェロモンを放出するように製剤化されたものである。交信撹乱剤を処理することで、雌雄の交尾を不成功に終わらせ、次世代の害虫発生を防ぐ目的で利用されている。
The attractant is a drug that is made close to the composition and amount of the sex pheromone used by insects to attract male adults. It is used for the purpose of grasping the generation time and generation amount of pests.
On the other hand, communication disrupters are formulated to release synthetic pheromones at a concentration more than 1000 times that of sex pheromones used by insects in order to disrupt sex pheromone communication between males and females. . It is used for the purpose of preventing the generation of next-generation pests by treating male and female unsuccessfully by treating the communication disruptor.

本発明の誘引剤と交信撹乱剤の使用に際し、ブチルヒドロキシトルエン、ブチルヒドロキシアニソール、ハイドロキノン、ビタミンE等の抗酸化剤や2−ヒドロキシー4−オクトキシベンゾフェノン等の紫外線吸収剤を適量加えても良い。適量とは、(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートとの合計重量に対して、例えば、抗酸化剤は1〜5重量%であり、紫外線吸収剤は1〜5重量%である。   When using the attractant and communication disruptor of the present invention, an appropriate amount of an antioxidant such as butylhydroxytoluene, butylhydroxyanisole, hydroquinone, vitamin E, or an ultraviolet absorber such as 2-hydroxy-4-octoxybenzophenone may be added. . The appropriate amount is, for example, 1 to 5% by weight of an antioxidant with respect to the total weight of (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate. The absorbent is 1 to 5% by weight.

本発明の誘引剤および交信撹乱剤は、有効成分の一定量の放出を長期間にわたり持続させるために、ゴム、ポリエチレン、ポリプロピレン、エチレン−酢酸ビニル共重合体、ポリ塩化ビニル等の放出量制御機能を有する物資からなるキャップ、細管、ラミネート製の袋、カプセル等の容器に充填して用いられる。   The attracting agent and communication disrupting agent of the present invention has a function of controlling the release amount of rubber, polyethylene, polypropylene, ethylene-vinyl acetate copolymer, polyvinyl chloride, etc. in order to maintain a certain amount of release of the active ingredient over a long period of time. It is used by filling a container such as a cap, a thin tube, a laminate bag, a capsule or the like made of a material having the above.

以下、本発明の具体的態様を実施例及び比較例によって説明するが、本発明は実施例に限定されるものではない。
実施例1〜7、比較例1〜3
表1に、誘引剤として使用した性フェロモン組成物の種類、組成及びその使用量を示した。これらに2.0重量%のブチルヒドロキシトルエンを添加したものをそれぞれイソプレンより成るゴムキャップに担持させ一晩放置後、白色粘着型トラップに取り付けた。
各性誘引剤がセットされた各トラップを、スモモヒメシンクイの発生が認められるスモモ圃場に5m間隔で、目通りの高さに吊した。5日に一度の間隔でそれぞれのトラップに捕獲されたスモモヒメシンクイ雄成虫の数を約2ヶ月間調べた。なお、この野外圃場試験は山梨県果樹試験場の協力によった。
Hereinafter, specific embodiments of the present invention will be described with reference to examples and comparative examples, but the present invention is not limited to the examples.
Examples 1-7, Comparative Examples 1-3
Table 1 shows the types and compositions of the sex pheromone compositions used as attractants and the amounts used. Those added with 2.0% by weight of butylhydroxytoluene were each supported on a rubber cap made of isoprene, allowed to stand overnight, and then attached to a white adhesive trap.
Each trap on which each sex attractant was set was hung at an expected height at intervals of 5 m in a plum field where the occurrence of plums was observed. The number of adult spruce moths captured in each trap at an interval of once every 5 days was examined for about 2 months. This field test was conducted in cooperation with the Yamanashi Fruit Tree Experiment Station.

比較例1〜3の誘引剤には一頭も誘引されなかったが、実施例1〜7には誘引が認められ、混合重量比が15:85の場合に(実施例1)誘引数が最大になることがわかる。   Although none of the attractants of Comparative Examples 1 to 3 was attracted, Examples 1 to 7 showed attraction, and the mixing argument was 15:85 (Example 1). I understand that

実施例8、比較例4
次に、本発明の性フェロモン組成物による交信撹乱の実例を示す。(E)−8−ドデセニルアセテートと(Z)−8−ドデセニルアセテートの重量比を6:94に調整した混合液に、安定剤としてBHTとスミソーブ300を各2重量%添加したものを、外径1.41mm、内径0.81mm、長さ20cmの高密度ポリエチレンの細管に封じ込め、徐放性の交信撹乱製剤とした。そして、20アールの日本梨園に計400本を均等に交信撹乱製剤を処理した。また、ここから直線距離で約500m離れた日本梨園を、交信撹乱剤を処理しない、いわゆる無処理対照園として設けた。
Example 8, Comparative Example 4
Next, the example of the communication disturbance by the sex pheromone composition of the present invention is shown. 2% by weight each of BHT and Sumisorb 300 are added as stabilizers to a mixed solution in which the weight ratio of (E) -8-dodecenyl acetate and (Z) -8-dodecenyl acetate is adjusted to 6:94. The product was encapsulated in a high-density polyethylene capillary having an outer diameter of 1.41 mm, an inner diameter of 0.81 mm, and a length of 20 cm to obtain a sustained release communication disruption preparation. Then, the communication disruption preparation was uniformly treated in a total of 400 in 20 Earl Nihonen. In addition, a Japanese pear garden that is about 500 m away from here was provided as a so-called untreated control garden that does not treat the communication disruptor.

これら二つの圃場に、スモモヒメシンクイの未交尾雌雄成虫を閉じ込めたステンレス製のカゴを吊り下げ、一晩放置後、雌成虫を解剖し、精包の有無を顕微鏡下にて調べて、各圃場一晩あたりの交尾率を調べた。その結果を表2に示す。   In these two fields, a stainless steel cage trapped with male and female adults of the spruce budworm was suspended and left overnight, and then the female adults were dissected and examined for the presence of spermatozoa under a microscope. The mating rate per night in the field was examined. The results are shown in Table 2.

交信撹乱剤が処理されていない圃場でのスモモヒメシンクイの交尾率(比較例4)は66%であったが、本発明の性フェロモン組成物より作成した交信撹乱剤を処理した圃場(実施例8)では、交尾率を5%に抑制することができたことがわかる。   Although the mating rate of the spruce budworm (Comparative Example 4) was 66% in the field where the communication disruptor was not treated, the field treated with the communication disruptor prepared from the sex pheromone composition of the present invention (implementation) In Example 8), it can be seen that the mating rate could be suppressed to 5%.
