Description

【０００１】
【発明の属する技術分野】
本発明は、松くい虫等の病虫害の防除方法と装置に関し、具体的に言えばマツノザイセンチュウの松への侵入又は侵入したマツノザイセンチュウの増殖を電撃によって抑制して松枯れを予防する松枯れ予防処理装置に関する。
【０００２】
【従来の技術】
出願人は平成８年７月１１日に「害虫被害を受けた立木の枯れ抑制方法」について特許出願をした（特願平８−１８２２０６；特開平１０−２３８５２）。本願発明の松枯れ予防処理装置は特願平８−１８２２０６に開示した装置を本願発明の「害虫による松枯れ予防法」に使用できるよう改良したものである。
【０００３】
【発明が解決しようとする課題】
マツノザイセンチュウの松への侵入又は侵入したマツノザイセンチュウの増殖を電撃によって抑制して松枯れを予防する松枯れ予防法は有効であるが、その予防法を効率的、且つ、効果的に実施するのは、数本の立ち木に対してならともかく、群生している松に対しては現実には不可能といってもよい。
【０００４】
本発明の目的は、大量の松に対しても効率的、且つ、効果的に電撃を加えてマツノザイセンチュウの松への侵入又は侵入したマツノザイセンチュウの増殖を抑制する装置を提供することにある。
【０００６】
【課題を解決するための手段】
カミキリが健全な松の樹枝に飛来して、その樹皮を餌としてかじり、その際カミキリの気門からマツノザイセンチュウ（以下、「線虫」という）が樹枝内に侵入する。樹枝内で線虫は増殖しながら樹幹内に拡散し、その増殖による水ストレスなどにより松は枯死する。
【０００７】
詳しく言えば、樹皮をかじった後、その傷口に数万匹の線虫が定着し、３日も経過するとその侵入部で脱皮、交尾、産卵、増殖を繰り返し、一週間もすると樹幹内に拡散していく。雌雄２対の線虫はほぼ１５日間で２６万匹にも増加する。２０日ぐらいすると、それ以後は線虫は世代交代を４，５日単位で繰り返し、一月も経つと樹幹全体に線虫が分布する。
【０００８】
本発明者は健全な松の幹の中ほどから頂部にかけて幹から延びている枝にカミキリが飛来する傾向があることを確認し、それらの枝で増殖し、幹に侵入、増殖する初期増殖段階で電撃を加えるのが最も効果的であり、また複数の枝に加えたパルス電圧は枝における線虫の増殖を抑制すると同時に、複数の枝から幹内にパルス電流が収束して大地に流れ、それにより幹内に既に侵入した線虫の増殖も抑制することを確認した。その抑制効果は、従来、樹幹に電撃を加えて線虫の増殖を抑制していた場合の効果に比して遥かに顕著である。
【０００９】
すなわち、上記の目的を達成する本発明の松枯れを予防する装置によれば、松の幹の中ほどから頂部にかけて幹から延びている枝のすべて、もしくはその中から複数の枝を選択し、それらの枝に電圧パルスを加えて枝から幹を通して電流パルスを大地に流し前記の枝に寄生した線虫の増殖活動を抑制する。現実には選択されない枝については線虫の増殖は避けられないが、高枝の枯死区域は効果的に限定される。実際に枝の選択は大きな枝、枝振りのよい枝についてなされることもある。
【００１０】
電圧パルスは、一方の極性の小振幅幅広のパルスに続く他方の極性の大振幅幅狭パルスから成り、この両極性電圧パルスを反復して印加する。一方の極性の小振幅幅広のパルスの印加は、後続する他方の極性の大振幅幅狭パルスを効果的に印加させる下ごしらえ的効果を奏し、また両パルスが接続するパルスの立下りと立ち上がりとは加わり合って線虫の増殖抑制に効果的な振幅となる。
【００１１】
すなわち、本発明の松枯れ予防処理装置は、一方の極性の小振幅幅広のパルスに続く他方の極性の大振幅幅狭パルスから成る両極性電圧パルスを発生するパルス発生装置と、このパルス発生装置に接続され、前記の両極性電圧パルスをあらかじめ定めた時間に発生させるタイマーとを備えた電圧パルス印加装置（１）と、そしてこの電圧パルス印加装置（１）から延びる複数の導体（２１）のそれぞれに取付けたパルス印加電極（２２と）を備え、前記の導体（２１）は松の幹の中ほどから頂部にかけて幹から延びている枝に前記の電極（２２）を取り付けるに足りる長さとなっており、さらに、前記のパルス発生装置（１）の非接地側の出力端子（１２）に抵抗を介して接続され、電圧パルス印加装置（１）のケーシングに絶縁して固定された先端がとがった電極（１４）を備えたことを特徴とする。
【００１２】
使用に当たっては、電圧パルス印加装置を樹幹に固定し、選択した高枝に電極を取付ければよい。タイマーで設定した時間に自動的に電圧パルスを加える。一実験例によれば１パルスでほぼ９日間増殖を抑制できる。
【００１３】
上記の予防処理方法を効率よく実施するための本発明の別の松枯れ予防処理装置は、一方の極性の小振幅幅広のパルスに続く他方の極性の大振幅幅狭パルスから成る両極性電圧パルスを発生するパルス発生装置、このパルス発生装置から延びる一本の導体に取付けたパルス印加電極、そして前記の導体をその長さにわたって支持し、前記の電極を頂端に支持する竿を備え、前記の導体と竿とは松の幹の中ほどから頂部にかけて幹から延びている枝に前記の電極を当てるに足りる長さとなっている。
【００１４】
作業員がこの竿を手に持って選択した高枝に電極を当て、電圧パルスを印加して予防処理を行う。
【００１５】
【発明の実施の形態】
図１と図２を参照する。健全な松の幹の中ほどから頂部にかけて幹から延びている枝（影をつけた部分）の中から複数の枝を選択し、これらの選択した枝に電圧パルスを加えて枝から幹を通して電流パルスを大地に流し前記の選択した枝に寄生した線虫の増殖活動を抑制する。図４に示すように電圧パルスは、一方の極性の小振幅幅広のパルス（振幅Ｅ１、幅Ｔ１）に続く他方の極性の大振幅幅狭パルス（振幅Ｅ２、幅Ｔ２）から成り、この両極性電圧パルスを反復して印加する。
【００１６】
上記の予防処理方法を効率よく実施する松枯れ予防処理装置を図１を参照して説明する。図１に示すように、松枯れ予防処理装置は両極性電圧パルス（図４参照）を発生するパルス発生装置と、このパルス発生装置に接続され、両極性電圧パルスをあらかじめ定めた時間に発生させるタイマー４とを備えた電圧パルス印加装置１を含み、さらに電圧パルス印加装置１から延びる複数の導体２１のそれぞれに取付けたパルス印加電極２２を含んでいる。導体２１は松の幹の中ほどから頂部にかけて幹から延びている枝に電極２２を取り付けるに足りる長さとなっている。

【００１８】
パルス幅調整回路７の出力端子はトランジスタ１０のベース電極に接続され、エミッター電極は設置されている。昇圧トランス１１の二次巻線１１ｂは電圧パルス印加装置１の出力端子１２，１３に接続され、一方の出力端子１２はケーブル２１を介して電極２２に接続され、高枝に電圧パルスを加え、他方の出力端子１３は接地されている。
【００１９】

BACKGROUND OF THE INVENTION
The present invention relates to a method and apparatus for controlling pests such as pine weevil, and more specifically, a pine that inhibits invasion of pine wood nematodes into pine or proliferation of pine wood nematodes by electric shock to prevent pine wilt. The present invention relates to a withering prevention processing apparatus .
[0002]
[Prior art]
On July 11, 1996, the applicant filed a patent application for “a method for suppressing withering of standing trees damaged by pests” (Japanese Patent Application No. 8-182206; Japanese Patent Application Laid-Open No. 10-23852). The apparatus for preventing pine wilt of the present invention is an improvement of the apparatus disclosed in Japanese Patent Application No. 8-182206 so that it can be used in the “method for preventing pine wilt caused by pests” of the present invention.
[0003]
[Problems to be solved by the invention]
Although pine tree nematode invasion into pine or the growth of invaded pine tree nematode is suppressed by electric shock, pine wilt prevention method is effective, but the prevention method is implemented efficiently and effectively. This is not possible for a few standing trees, but it is actually impossible for a group of pine trees.
[0004]
An object of the present invention is efficient against a large amount of pine, and, effectively providing apparatus for suppressing growth of nematode invaded or invasion of pine nematode added lightning is there.
[0006]
[Means for Solving the Problems]
The beetle flies to a healthy pine tree branch and gnaws its bark as food. At that time, the pine wood nematode (hereinafter referred to as “nematode”) enters the tree branch. Nematodes spread within the tree trunk while growing in the tree branches, and the pine trees die off due to water stress caused by the growth.
[0007]
More specifically, after biting the bark, tens of thousands of nematodes settle on the wound, and after 3 days, the molting, mating, egg-laying, and multiplication are repeated at the invading part, and after a week, they diffuse into the trunk. I will do it. Two pairs of male and female nematodes increase to 260,000 in almost 15 days. After about 20 days, nematodes repeat generation changes every 4 or 5 days, and after a month, nematodes are distributed throughout the trunk.
[0008]
The inventor has confirmed that there is a tendency for the beetles to fly to the branches extending from the trunk from the middle to the top of a healthy pine trunk, proliferates in those branches, invades the trunk, and proliferates the initial growth stage It is most effective to apply an electric shock at the same time, and the pulse voltage applied to multiple branches suppresses the growth of nematodes on the branches, and at the same time, the pulse current converges from the multiple branches into the trunk and flows to the ground, As a result, it was confirmed that the growth of nematodes that had already entered the trunk was also suppressed. The inhibitory effect is far more remarkable than the effect of conventionally suppressing the growth of nematodes by applying electric shock to the trunk.
[0009]
That is, according to the device of the present invention that prevents the pine wilt of the present invention that achieves the above object, select all of the branches extending from the trunk from the middle to the top of the trunk of the pine, or select a plurality of branches from the branches, A voltage pulse is applied to these branches, and a current pulse is passed from the branches through the trunk to the ground to suppress the proliferation activity of nematodes parasitic on the branches. For branches that are not actually selected, the growth of nematodes is inevitable, but the dead areas of the high branches are effectively limited. In fact, branch selection may be made for large branches or branches with good branching.
[0010]
The voltage pulse is composed of a small amplitude wide pulse of one polarity followed by a large amplitude narrow pulse of the other polarity, and this bipolar voltage pulse is repeatedly applied. The application of a small-amplitude wide pulse of one polarity has a preparatory effect that effectively applies a subsequent large-amplitude narrow pulse of the other polarity, and the fall and rise of the pulse connected by both pulses Together, the amplitude is effective in suppressing the growth of nematodes.
[0011]
That is, the pinion prevention processing device of the present invention includes a pulse generator that generates a bipolar voltage pulse composed of a small amplitude wide pulse of one polarity followed by a large amplitude narrow pulse of the other polarity, and the pulse generating device. And a voltage pulse applying device (1) having a timer for generating the bipolar voltage pulse at a predetermined time, and a plurality of conductors (21) extending from the voltage pulse applying device (1 ) . Each has a pulse application electrode (22) attached thereto, and the conductor (21) has a length sufficient to attach the electrode (22) to a branch extending from the middle to the top of the pine trunk. and, further, the non-ground side of the output terminal (12) via a resistor connected, fixed is then insulated casing of the voltage pulse application device (1) of the pulse generator (1) Wherein the tip is provided with electrodes (14) pointed.
[0012]
In use, the voltage pulse applying device is fixed to the tree trunk, and an electrode is attached to the selected high branch. A voltage pulse is automatically applied at the time set by the timer. According to one experimental example, growth can be suppressed for approximately 9 days with one pulse.
[0013]
Another pinion prevention processing apparatus of the present invention for efficiently carrying out the above prevention processing method is a bipolar voltage pulse comprising a small amplitude wide pulse of one polarity followed by a large amplitude narrow pulse of the other polarity. A pulse applying electrode attached to a single conductor extending from the pulse generating device, and a rod for supporting the conductor over its length and supporting the electrode at the top end, The conductors and ridges are long enough to apply the electrodes to the branches extending from the middle to the top of the pine trunk.
[0014]
An operator places the electrode on the high branch selected by holding this bag in his hand and applies a voltage pulse to prevent the treatment.
[0015]

As shown in FIG. 4, the voltage pulse is composed of a small amplitude wide pulse (amplitude E1, width T1) of one polarity followed by a large amplitude narrow pulse (amplitude E2, width T2) of the other polarity. A voltage pulse is applied repeatedly.
[0016]
