Description
Technical Field
The invention relates to a gel for preventing and treating stem borers and application thereof.
Background
Trunk borers mainly eat main trunks, branches and other parts of trees, and live in hidden life with larvae in the trees for a long time, so that the trees are sore and have holes, the conducting and transporting tissues are damaged, the transportation of nutrients and water is blocked, the trees are poor in growth, leaves are yellow, branches are withered, the wood quality and the fruit yield are affected, the ornamental value is reduced, the trees die in severe cases, and the damaged branches and trunks of the trees are easy to break and hurt pedestrians and vehicles.
The trunk borers mainly comprise longicorn, bark beetle, sulcus orbital elephant and the like, eggs are laid in bark of adults, and larvae gradually enter phloem, cambium and xylem after hatching to cause harm. Because the insect population is slightly influenced by environmental conditions in a tree body, the insect population is less, the insect population density is relatively stable, and the prevention difficulty is higher. The method for controlling the stem borers by utilizing natural enemies such as scleroderma guani, beauveria bassiana, pathogenic nematodes and the like is the most environment-friendly method, but the production, transportation, storage, multiplication and release of the natural enemies all need certain environmental conditions, the technical difficulty is high, and the application effect is not ideal. Tests show that the prevention and control effects of trunk borers are not ideal when the roots are filled with or buried with drugs, the trunks are punched and filled with drugs or bags are hung on the trunks, and the drug bottles are inserted. The liquid medicine is filled into the moth holes or the excrement discharge holes, so that the pesticide has a good effect of preventing trunk borers which are damaged by eating downwards; for the trunk borers eating upwards or having a plurality of defecation holes, the liquid medicine is easy to run off, and the control effect is obviously reduced.
The Qiaojian is equal to that of 2010, the paste for preventing and treating the stem borers is published, patent invention authorization is obtained in 2013, the paste is ZL 201010592873.8, the paste has certain fluidity and moderate viscosity, the problem that liquid medicine is easy to run off is solved, and the paste has good prevention and treatment effects on the stem borers of one insect, such as anoplophora glabripennis, anoplophora chinensis, rust-colored anoplophora glabripennis, longicorn, mulberry longicorn and the like, but the paste has a relatively quick volatilization, so that the prevention effect on the species with more insects and more excretory holes, such as the small linear horn moth.
