ことで松の木を保護するようにしたものである。[Prior Art and Problems to be Solved by the Invention] The pine beetle, which is a pest that eats away at pine trees, is carried in large numbers at a time by the pine beetle insect and becomes parasitic on the pine tree, quickly causing the tree to wither. Previously, in order to prevent pine blight damage, pine tree beetles were killed by injecting insecticides into pine trees.
It is troublesome as it is necessary to inject insecticide into many parts many times, and furthermore, it is difficult to completely kill insects because there are an infinite number of insecticides. For this reason, the current situation is to cut down and burn pine trees in order to prevent further damage from pine blight. Therefore, the present invention is designed to protect pine trees by electrically killing pine tree insects.
このため本発明は、マツシブ・ｆセン虫に食われている
松に電流を流すことにより、マツノザイセン虫を！＋！
電死させる方法としている。For this reason, the present invention eliminates the pine beetles by passing an electric current through the pine trees that are being eaten by the pine beetles. +!
It is a method of electrocution.

較的弱い電流でよいのである。By passing an electric current through a pine tree that has been eaten by pine beetles, the pine beetles inside will be electrocuted while being grounded from the tree through the trunk and branches due to its high conductivity. In particular, since the pine beetle is parasitic in humid areas, a relatively weak current is sufficient.
以下、本発明の詳細な説明する。

１アンペアが妥当である。The present invention will be explained in detail below. First, using a DC voltage battery with an ammeter as a voltage application device, turn on the battery with one electrode placed against a pine tree and the other electrode grounded to the ground.
A direct current of several tens of amperes is applied. As a result, while the current flows from the tree through the trunk and branches to ground, it also flows to the pine beetle inside, causing electrocution. It has been found that the current required to kill pine woodworms is inversely proportional to the pine wood resistance to the 0.8th power, and as the surrounding resistance increases, it is easier for the current to pass through the body of the pine woodworm. It seems to flow in a concentrated manner. Therefore, several tens of amperes per 10 meters of tree height is appropriate.
