【産業上の利用分野】
本発明はカメムシ類の防除方法並びに加害防止方法に関する。
【０００２】
【従来の技術及び発明の解決課題】
害虫防除のため、従来より有機リン酸エステル系の化合物が使用されてきているが、中でも、特許出願公告昭和３５年第１５０２１号には、チオノリン酸エステルのいくつかの化合物が例示され、それらが殺虫活性を有することが記載されている。そしてそのうち、化学名Ｏ，Ｏ−ジメチル Ｏ−（４−メチルスルフィニル−ｍ−トリル）ホスホロチオエートに相当する化合物が、特許出願公開昭和５５年第１２７３０４号に記載されるように、マツ類の枯損防止剤として有効であることが知られている。
森林資源の保護育成のための杉、桧等の林木種子の採種事業に於いて、カメムシ類による吸汁害が著しいことから、その対策が大きな問題になっている。そして、これまで有効な対策がみつけられていない。また果樹栽培（ミカン、梨、桃、リンゴ等々）に於いても、カメムシ類による被害は、収穫時の果実への直接害であることから、経済的に甚大であり、その対策が求められている。
【０００３】
【課題解決のための手段】
本発明者は、従前よりよく知られた化合物を用いる新しいカメムシ類の防除方法並びに加害防止方法を発見した。即ち、本発明は、有効成分として、Ｏ，Ｏ−ジメチル Ｏ−（４−メチルスルフィニル−ｍ−トリル）ホスホロチオエートを含有する殺虫組成物を樹幹内に導入することにより、カメムシ類を防除することを特徴とするカメムシ類の防除方法、並びに、みかん、梨、桃、リンゴ等の栽培果樹の周囲に隣接して、カメムシ類の宿主である桧を移植し、該桧の樹幹内に上記殺虫組成物を導入し、それをもって、カメムシ類を防除することによって、該果樹類に対するカメムシ類の加害を防止する方法を提供するものである。
本発明で用いられる活性化合物は、前記特開昭５５−１２７３０４号に記載されるようにマツ類の枯損防止剤として有効であり、特にマツノザイセンチュウ（Ｂｕｒｓａｐｈｅｌｅｎｃｈｕｓ ｘｙｌｏｐｈｉｌｕｓ Ｎｉｃｋｌｅ ）に対する殺センチュウ効果を示すものである。
【０００４】
本発明者は、意外にも、この活性化合物を、カメムシ類の加害対象である杉、桧の樹幹内に導入することによって、カメムシ類の吸汁の結果、極めて的確に、これらの害虫を防除することができることを見い出した。
本発明の防除方法を用いることにより、杉、桧の採種に於けるカメムシ類による被害を防ぐことができるとともに、カメムシ類の幼虫の好餌である種子それ自体もより健全に保たれ、また収量も著しく増大し、且つ収穫種子の発芽率も、良好であることが確認された。
更に、本発明者等は、全く新しい発想による上記防除方法を応用することによる果樹栽培に於けるカメムシ類の加害防止方法を発見した。すなわち、詳細には、みかん、梨、桃、リンゴ等の栽培果樹の周囲に隣接して、桧を植えることにより、桧を宿主として好むカメムシ類を誘引し、そして予め該桧の樹幹内に前記殺虫組成物を導入しておくことによって、カメムシ類の吸汁の結果、カメムシ類を防除し、間接的に果樹栽培に於けるカメムシ類の加害を未然に防ぐという全く新しい防除体系である。
更に、この防止方法の特筆すべき点は、食用に供する果樹には、全く活性化合物の被曝がないことから、より安全な果実を提供することができる。
【０００５】
本発明のカメムシ類の防除方法並びに加害防止方法に於いて、その対象であるカメムシ類の種類としては、次のものを例示できる。
チャバネアオカメムシ （Ｐｌａｕｔｉａ ｃｒｏｓｓｏｔａ）
クサギカメムシ （Ｈａｌｙｏｍｏｒｐｈａ ｈａｌｙｓ）
アオクサカメムシ （Ｎｅｚａｒａ ａｎｔｅｎｎａｔａ）
ミナミアオカメムシ （Ｎｅｚａｒａ ｖｉｒｉｄｕｌａ）
ツヤアオカメムシ （Ｇｌａｕｃｉａｓ ｓｕｂｐｕｎｃｔａｔｕｓ）。
【０００６】
本発明に於ける活性化合物の樹幹内への導入方法としては、ドリル等で穴をあけ、そこに該化合物を含有する殺虫組成物を導入することが一般的であり、具体的には、液状の該組成物を注入するか、又は、固状の該組成物を埋め込む方法が提供され、特に好ましくは、固状組成物の埋め込みの方法があげられる。
本発明の防除方法は、採種用の杉及び桧に適用することが、最も好適であるが、この方法は、これのみに限定されるものでなく、斯る方法を用いることにより、カメムシ類の防除を達成し得るすべての対象林木に適用し得るものである。
本発明の果樹類に対するカメムシ類の加害防止方法に於いて、果樹類の例としては、みかん、梨、桃、リンゴをあげることができるが、これ以外にも、カメムシ類の加害対象になり得る果樹類に対しても、本発明の加害防止方法は有効であり、本発明は、例示以外の果樹類を包含する。
【０００７】
本発明で用いる殺虫組成物の製剤形態としては、液剤、ペースト、スティック状固形剤を例示できる。また本発明の方法の実施形態から、殺虫組成物を樹幹内に導入できる上記製剤形態以外の製剤形態も本発明は包含する。
これら製剤は、当該分野における通常の公知方法により、製造でき、例えば活性化合物を、液体希釈剤及び／又は担体及び／又は界面活性剤等を用いて、混合することにより調製されることができる。更に、必要ならば、補助剤も使用することができる。
該製剤は、その他の農薬、例えば殺虫剤、殺菌剤、植物成長調整剤並びに肥料等をも含有してよい。
【０００８】
液体希釈剤としては、例えば、芳香族炭化水素類（例えば、キシレン、トルエン、アルキルナフタレン等）、クロル化芳香族又はクロル化脂肪族炭化水素類（例えば、クロロベンゼン類、塩化エチレン類、塩化メチレン等）、脂肪族炭化水素類〔例えばシクロヘキサン等、パラフィン類（例えば鉱油留分等）〕、アルコール類（例えば、ブタノール、グリコール及びそれらのエーテル、エステル等）、ケトン類（例えば、アセトン、メチルエチルケトン、メチルイソブチルケトン又はシクロヘキサノン等）、強極性溶媒（例えば、ジメチルホルムアミド、ジメチルスルホキシド等）そして水も挙げることができる。
担体としては、例えば、土壌天然鉱物（例えば、カオリン、クレー、タルク、チョーク、石英、アタパルガイド、モンモリロナイト又は珪藻土等）、土壌合成鉱物（例えば、高分散ケイ酸、アルミナ、ケイ酸塩等）、粉砕且つ分別された岩石（例えば、方解石、大理石、軽石、海泡石、白雲石等）、無機及び有機物粉の合成粒、そして有機物質（例えば、おがくず、ココやしの実のから、とうもろこしの穂軸そしてタバコの茎等）の細粒体を挙げることができる。
【０００９】
界面活性剤としては、例えば、非イオン及び陰イオン乳化剤〔例えば、ポリオキシエチレン脂肪酸エステル、ポリオキシエチレン脂肪酸アルコールエーテル（例えば、アルキルアリールポリグリコールエーテル、アルキルスルホン酸塩、アルキル硫酸塩、アリールスルホン酸塩等）〕、アルブミン加水分解生成物を挙げることができる。
本発明に於ける活性化合物の使用濃度は、約２５〜約６０重量％であり、好ましくは約５０重量％である。

[Industrial applications]
The present invention relates to a method for controlling stink bugs and a method for preventing damage.
[0002]
2. Description of the Related Art
For the control of insect pests, organophosphate compounds have been used in the past. Among them, Patent Application Publication No. 15021, No. 15021, illustrates some compounds of thionophosphate esters. It is described as having insecticidal activity. Among them, a compound corresponding to the chemical name of O, O-dimethyl O- (4-methylsulfinyl-m-tolyl) phosphorothioate is described in Japanese Patent Application Publication No. 127304/1982. It is known to be effective as an agent.
In the seeding business of forest tree seeds such as cedars and cypresses for the protection and fostering of forest resources, measures against stinging by stink bugs have become a serious problem due to the remarkable sucking damage. And no effective measures have been found so far. In fruit tree cultivation (tangerines, pears, peaches, apples, etc.), stink bugs are directly harmful to fruits at the time of harvest, so they are economically enormous. I have.
[0003]
[Means for solving the problem]
The present inventors have discovered new stink bug control and harm prevention methods using previously well known compounds. That is, the present invention controls stink bugs by introducing an insecticidal composition containing O, O-dimethyl O- (4-methylsulfinyl-m-tolyl) phosphorothioate as an active ingredient into a tree trunk. A method for controlling stink bugs, and, adjacent to the periphery of cultivated fruit trees such as tangerines, pears, peaches, and apples, transplanting cypress, which is a host of stink bugs, into the trunk of the cypress And a method for controlling stink bugs, thereby preventing damage to stink bugs on the fruit trees.
The active compound used in the present invention is effective as a pine mortality inhibitor as described in the above-mentioned JP-A-55-127304, and particularly shows a nematicidal effect on Bursaphelenchus xylophilus Nickle. It is.
[0004]
The present inventors surprisingly, by introducing this active compound into the trunks of cedars and cypresses that are the target of stink bugs, as a result of sucking stink bugs, extremely accurately control these pests. I found that I could do it.
By using the control method of the present invention, it is possible to prevent damage by stink bugs in seeding of cedars and cypresses, and the seeds themselves, which are the bait of stink bug larvae, are also kept healthy and yield. And the germination rate of the harvested seeds was also confirmed to be good.
Furthermore, the present inventors have discovered a method for preventing stink bugs from infesting fruit trees by applying the above control method based on a completely new idea. That is, in detail, oranges, pears, peaches, adjacent to the periphery of cultivated fruit trees such as apples, by planting cypress, attracts stink bugs that prefer cypress as a host, and in advance in the trunk of the cypress By introducing the insecticidal composition, the stink bugs are sucked by the stink bugs, thereby controlling the stink bugs and indirectly preventing the stink bugs from being damaged in fruit tree cultivation.
Furthermore, a remarkable point of this prevention method is that fruit trees to be edible are not exposed to the active compound at all, so that safer fruits can be provided.
[0005]
In the method for controlling stink bugs and the method for preventing harmful insects according to the present invention, the following can be exemplified as the types of stink bugs to be treated.
Brown stink bug (Plautia crossota)
Halyomorpha halys
Blue stink bug (Nezara antennanata)
Southern stink bug (Nezara viridula)
Glaucias subpunctus.
[0006]
As a method for introducing the active compound into the trunk of the present invention, it is general to make a hole with a drill or the like, and to introduce an insecticidal composition containing the compound into the hole. Or a method of embedding the composition in a solid state, and particularly preferably a method of embedding the solid composition.
The control method of the present invention is most preferably applied to cedar and cypress for seeding, but this method is not limited thereto, and by using such a method, stink bugs can be controlled. It can be applied to all target forest trees that can achieve control.
In the method for preventing stink bugs from injuring fruit trees of the present invention, examples of orchards include tangerines, pears, peaches, and apples, but in addition to these, they can be infested by stink bugs. The method for preventing damage of the present invention is also effective for fruit trees, and the present invention includes fruit trees other than those exemplified.
[0007]
Examples of the formulation of the insecticidal composition used in the present invention include a liquid agent, a paste, and a stick-like solid agent. In addition, the present invention also encompasses pharmaceutical forms other than the above-mentioned pharmaceutical forms that enable the insecticidal composition to be introduced into the trunk, according to the embodiment of the method of the present invention.
These preparations can be produced by a known method in the art, and can be prepared, for example, by mixing the active compound with a liquid diluent and / or a carrier and / or a surfactant. In addition, if necessary, auxiliary agents can be used.
The formulation may also contain other pesticides such as insecticides, fungicides, plant growth regulators, fertilizers and the like.
[0008]
Examples of the liquid diluent include aromatic hydrocarbons (eg, xylene, toluene, alkylnaphthalene, etc.), chlorinated aromatic or chlorinated aliphatic hydrocarbons (eg, chlorobenzenes, ethylene chlorides, methylene chloride, etc.) ), Aliphatic hydrocarbons (eg, cyclohexane, etc., paraffins (eg, mineral oil fractions, etc.)), alcohols (eg, butanol, glycol and their ethers, esters, etc.), ketones (eg, acetone, methyl ethyl ketone, methyl) Mention may also be made of isobutyl ketone or cyclohexanone, strong polar solvents (eg dimethylformamide, dimethylsulfoxide, etc.) and water.
As the carrier, for example, soil natural minerals (eg, kaolin, clay, talc, chalk, quartz, attapull guide, montmorillonite or diatomaceous earth), soil synthetic minerals (eg, highly dispersed silicic acid, alumina, silicate, etc.), pulverized And fractionated rocks (eg, calcite, marble, pumice, sepiolite, dolomite, etc.), synthetic grains of inorganic and organic flour, and organic substances (eg, sawdust, coconut, corn cob and Fine granules such as tobacco stems).
[0009]
Examples of the surfactant include nonionic and anionic emulsifiers [eg, polyoxyethylene fatty acid ester, polyoxyethylene fatty acid alcohol ether (eg, alkylaryl polyglycol ether, alkyl sulfonate, alkyl sulfate, aryl sulfonic acid) And the like) and albumin hydrolysis products.
The use concentration of active compound in the present invention is about 25 to about 60% by weight, preferably about 50% by weight.
Next, the contents of the present invention will be specifically described with reference to examples, but the present invention is not limited thereto.
