Anoplophora chinensis biological prevention method

Abstract

The invention provides an anoplophora chinensis biological prevention method. According to the method, prevention agents with different formulas are used in different growth stages of anoplophora chinensis, thus being strong in pertinence; in egg stage of anoplophora chinensis, bacillus thuringiensis fermentation broth, adonis amurensis extractive juice and absolute ethyl alcohol are matched for use, and the killing rate of anoplophora chinensis eggs is 100%; in larval stage, the bacillus thuringiensis fermentation broth, melia toosendan extractive juice and absolute ethyl alcohol are matchedfor use, and the kill rate of anoplophora chinensis larva is up to 97% or above; in the adult stage, the bacillus thuringiensis fermentation broth, hydrogen peroxide, absolute ethyl alcohol and adonisamurensis extractive juice are matched for use, and the kill rate of adult anoplophora chinensis is up to 98% or above. The number of anoplophora chinensis can be effectively prevented, the application of zinc phosphate, aluminum phosphate and other toxic chemical pesticides can be avoided, the environment pollution can be alleviated, the biological bacillus thuringiensis fermentation broth mainly adopted has no harm to people and livestock, and belongs to a biological insecticidal source having high safety.

Description

Technical field [0001] The invention belongs to the technical field of biological control, and in particular relates to a method for biological control of longicorn beetle. Background technique [0002] The star beetle mainly harms many trees such as phalanx, apple, pear, poplar, elm, and willow, but it is an important stem-boring pest that harms phalanx trees in urban greening trees. Due to its strong growth potential, large crown, and strong adsorption capacity for pollutants, the Phyllostachys vulgaris is one of the important landscaping tree species in my country. In recent years, the hazards and occurrence of longhorn beetles have become more and more serious. They have been flooded in many places, causing a large number of deaths or poor growth and frequent deaths, causing huge losses to the ecological environment and urban greening. It has become urban forestry and garden greening. , Major pests of ecological city construction and development. [0003] At present, most res...

Problems solved by technology

However, due to the long life history of the star beetle, its eggs, larvae and pupae all live in the trunk, the individuals are scattered, live alone, and are rarely affected by external adverse conditions, so the control effect is not ideal

At the same time, paulownia is generally used as a garden or urban greening tree species. The use of a large amount of chemical pesticides will undoubtedly cause pollution to the ecology and human settlements and lack of sustainability, which is contrary to the purpose of people's cultivation of paulownia to improve the environment.
