Problems solved by technology

Trapping and killing adults with environmentally friendly and protective agricultural and forestry insecticidal lamps or black light lamps has limited killing effect and cannot completely kill adults
②Injecting medicine control: injecting medicine into wormholes to kill pests, and injecting medicines starts to prevent and control after pests penetrate into trees, and the damage has already occurred. This method is labor-intensive and time-consuming, and is not conducive to large-scale control
At present, there is no good control method that has a good control effect when it is harmful.

Embodiment 1

[0012] A method for preventing and controlling forestry pests, comprising the following steps:

[0013] (1) Insecticide spraying: 7 days after the discovery of the adult beetle moth, the 5-year-old ginkgo was sprayed with insecticides on the stems and leaves of the whole plant, once at intervals of 15 days, and 3 times in a row. The insecticide is 40% dimethion, the concentration is 1ppm, and 2.5% deltamethrin 2.5ppm is added for 1; 2.5 mixing.

[0014] (2) Pruning: Before overwintering, prune the branches that are still infested with insects and cause them to wither, and the pruned branches are burned intensively.

[0015] (3) Re-control in the second year: In the coming year, spray insecticides on the stems and leaves of the whole plant again after 7 days after the adults of the small beetle moth. The concentration of methapon is 1ppm, add 2.5% deltamethrin 2.5ppm for 1; 2.5 mixing.

[0016] Before overwintering, no damaged branches were found.

Embodiment 2

[0018] A method for preventing and controlling forestry pests, comprising the following steps:

[0019] (1) Insecticide spraying: 7 days after the discovery of the adult beetle moth, the 4-year-old eucalyptus was sprayed with insecticides on the stems and leaves of the whole plant, once every 15 days, and 3 times in a row. The insecticide is 40% dimethion, the concentration is 1ppm, and 2.5% deltamethrin 2.5ppm is added for 1; 2.5 mixing.

[0020] (2) Pruning: Before overwintering, prune the branches that are still infested with insects and cause them to wither, and the pruned branches are burned intensively.

[0021] (3) Re-control in the second year: In the coming year, spray insecticides on the stems and leaves of the whole plant again after 7 days after the adults of the small beetle moth. The concentration of methapon is 1ppm, add 2.5% deltamethrin 2.5ppm for 1; 2.5 mixing.

[0022] Before overwintering, no damaged branches were found.

Abstract

A prevention and treatment method for forest pests comprises the following operating steps: complete-stool stem leaf pesticide spraying is conducted seven days after holcocerus insularis staudinger imagos are found; spraying is conducted at intervals of 15 days for three times continuously; branches withered due to insect pests before overwintering are trimmed; the trimmed branches are incinerated in a centralized manner; and next year, pesticide spraying is conducted once more seven days after holcocerus insularis staudinger imagos are found. Through the embodiment of the prevention and treatment method, the insecticidal effect is good; the labor intensity is low; through two years of government, radical treatment of insect pest in a large area can be realized.

Description

technical field [0001] The invention relates to the technical field of tree maintenance, and mainly relates to a method for preventing and controlling forestry pests of the small brown wood beetle moth. Background technique [0002] Lesser horned wood beetle moth, Holcocerus insularis Staudinger, belonging to the order Lepidoptera, is an insect of the genus Lepidopteridae. parasitic on hawthorn , crabapple ,ginkgo, Magnolia , lilac, cherry blossom, elm leaf plum, crape myrtle ,white wax, toon , Yellow Thorn Rose , pentagonal maple, eucalyptus, etc. The larvae eat the xylem of the branches of flowers and trees, and dozens to hundreds of them gather in the borer channel to cause damage. The light ones cause the wind to break the branches, and the severe ones cause the flowers and trees to die gradually, causing great economic losses to the seedling farmers and seriously affecting the effect of urban greening and beautification. This worm takes place in one gene...
