Method for preventing and killing pests of longhorn beetle

Abstract

The invention discloses a method for preventing and killing pests of longhorn beetle. The method is characterized by comprising the following steps that small cotton swabs which are dipped in omethoate are inserted into wormy places on a fruit tree; then an emulsion is prepared from fluorescent powder, quick lime and water according to a proportion of 1:(45-80):(200-300); and the emulsion is uniformly coated on a tree trunk and a bare root on the ground surface, and the places with the cotton swab are coated with the emulsion. The wormy places of the fruit tree are inserted by the small cottonswabs which are dipped in the omethoate, so that the pests of longhorn beetle can be killed; then the emulsion is prepared according to a certain proportion, so that white light reflection of the quick lime in the day time is utilized to prevent adult longhorn beetles from oviposition and parasitism, and at the same time, the theory that the fluorescent powder can absorb light energy during the daytime and emit light at night is utilized to prevent the adult longhorn beetles from oviposition and parasitism at night; and in addition, the emulsion provides alkaline environment, and thus has a good prevention effect on other pests and diseases.

Description

Technical field [0001] The invention belongs to a technology for removing insects, and specifically relates to a method for preventing and repelling longhorn beetles. Background technique [0002] Longhorn beetle pests are important stem-boring pests of many forest trees, fruit trees, and flowers. Its periodic outbreaks often cause huge economic losses in forestry and fruit industry. Dry branches in orchards are mostly caused by longhorn beetles. Female adults of long beetles pierce the ovipositor into the xylem of twigs, causing egg-laying nests and laying eggs in them. The eggs develop into larvae, and the wounds of the nests are linear Splitting directly destroys the water and nutrient transport of the branches, resulting in withered branches and leaves. The larvae stage is the most severe. The larvae eat inside the fruit tree to hollow out the trunk, which affects the normal growth and life of the fruit tree, and also affects the production yield. Insect-eaten trees and sus...

Problems solved by technology

The larval stage is the most severe. The larvae eat inside the fruit tree and make the trunk hollow, which affects the normal growth and lifespan of the fruit tree, and also affects the production output.
