Method for controlling Chinese pine caterpillars

Abstract

The invention discloses a method for controlling Chinese pine caterpillars, which aims to achieve the efficient and thorough control effect. The method for controlling the Chinese pine caterpillars comprises the following steps of: mixing 2.5 percent deltamethrin with diesel oil in a mass ratio of 1:(15-18) to obtain a pesticide, spraying the pesticide to form a pesticide ring with the width of between 5 and 7cm at a position, which is 0.8 to 1m away from the ground, on a trunk by using a plastic atomizer, and fixing a plastic ring with the width of between 5 and 7cm above the pesticide ring on the trunk. In the method, medicaments and plastic cloth have lower expenses, the control cost is low, and the ecological pollution is low; the method is suitable to be promoted in Chinese pine forests of which the trunks are higher in forest land; meanwhile, the death rate of the Chinese pine caterpillars can reach 93 percent by using the pesticide ring and the plastic ring to control the Chinese pine caterpillars.

Description

Technical field [0001] The present invention relates to a method for controlling pine caterpillars. Background technique [0002] The Chinese pine caterpillar is one of the devastating leaf-eating pests in the Chinese pine forest. In severe cases, it can eat up the pine needles, which will seriously affect the growth of the Chinese pine forest. If it is damaged for years, the pine tree will die. At present, pesticide spraying is generally used to prevent and control pine caterpillars. However, due to the living habit of pine caterpillars under the trees to live through the winter and go up the trees in the spring of the following year, the effect of thorough prevention and control cannot be achieved. Summary of the invention [0003] The purpose of the present invention is to provide a method for preventing and controlling Dendrolimus tabulaeformis, so as to achieve the effect of high efficiency and thorough prevention and control. [0004] The present invention is realized through...

AI Technical Summary

Problems solved by technology

At present, spraying pesticides is generally used to prevent and control Chinese pine caterpillars, but because the living habit of Chinese pine caterpillars is to go down the tree and overwinter, and then climb up the tree in the next spring, it is impossible to achieve a thorough control effect.
