Abstract

The invention discloses a method for preventing the harm from North-America red-maple long-horned beetles, and the method comprises the steps: employing 30% phoxim microcapsule to achieve 500-time dilution and employing 20% imidacloprid to achieve 500-time dilution during the middle ten days of April, so as to carry out root irrigation; employing and spraying green weilei (microcapsule water aqua produced by Chongqing Zonbon Pesticides and Medicals (groups) Co., Ltd.), diluted 400 times, and silica gel to tree trunks in the range from the ground to a position at a height of 80 cm during the middle ten days of June; and manually capturing adult pests during the last ten days of June when the adult pests come out for eating and mating. The method can prevent the long-horned beetles from slotting and laying eggs at a root, can kill laid eggs, prevents the eggs from being hatched and becoming larvae, prevents the larvae and mature larvae from entering into the tree trunks, enables the rate of insect pest of wood to be reduced to less than 20%. Moreover, the poison is low, the residual is small, and the method is safe.

Description

A kind of method of preventing and treating the red maple Anoplophora glabripennis in North America

technical field:

The present invention relates to techniques of pest control field, specifically prevent and treat the method for the red maple Anoplophora glabripennis in North America.

background technology:

The red maple in North America (Acer rubrum L.) is world-renowned ornamental trees and shrubs.Nearly 5 years, in the red maple process in introducing and planting North America, China various places, the harm of anoplophora glabripennis was the most serious, and difficulty of governance is maximum.

The harm of anoplophora glabripennis to the red maple in North America is mainly, and becomes insect bite food bark, leaf, and bites from tree body root, cutting, to lay eggs; Larvae at bark and xylembetween take food, particularly gnaw bark at root cap position, cause trees weak even dead; Mature larva is eaten into into xylem, and survives the winter in root xylem.

Because anoplophora glabripennis has, diffusivity is strong, growth rate is fast, mortality is high, life area is hidden, current using method is mainly artificial capture method, biological control, chemical control, traditional prevention and controls is difficult to control spreading of insect pest fast and effectively, even causes environmental pollution and the injury to people, animal.

summary of the invention:

Technical problem to be solved by this invention be to provide a kind of can long-acting, environmental protection, low toxicity control anoplophora glabripennis to the method for the red maple insect pest in North America.

The technical solution used in the present invention comprises the following steps:

(1) mid-April, dilute 500 times of+20% Imidacloprid with 30% Phoxim microcapsule and dilute 500 times of filling roots, around trunk, form the pesticide-clay mixture of diameter 20-40cm.

(2) trunk is sprayed with the Lu se weilei+silica gel of dilution 400 times mid-June.

(3) mid or late June, when adult is out taken food with mating, manually flutter and catch.

Phoxim microcapsule described in step (1) has slow release characteristic, makes the drug effect phase extend to more than 6 months, with Imidacloprid with the use of, enhance the effect killed rapidly.

Trunk spraying altitude described in step (2) is more than ground in 80 cm range.

Lu se weilei described in step (2) is a kind of touch-broken microcapsule aqua, can break immediately when longicorn steps on tactile, the former medicine discharged adheres to longicorn foot and enters in body, kill longicorn, do not preserved by the capsule stepped on brokenly is intact after using, avoiding agricultural chemicals, to reuse the waste drug effect caused rapid, lasting period is long, micro-poison is to person poultry safety, residual low in the environment.

Lu se weilei described in step (2) is the Lu se weilei of dilution 400 times, sprays trunk after mixing with silica gel.

Beneficial effect: the present invention is for solving the custom-designed a kind of prevention and controls of North America red maple anoplophora glabripennis insect pest, longicorn can be intercepted lay eggs in the cutting of rhizome place, and parasite elimination ovum can be killed, prevent larvae and mature larva from entering trunk, trees insect pest rate can be down to less than 2%, and low toxicity, low-residual, to person poultry safety.

embodiment:

Example 1.

In late April, 2013, dilute 500 times of+20% Imidacloprid with 30% Phoxim microcapsule and dilute 500 times of filling roots; Mid-June, spray trunk in the tree above 100cm in body ground with the Lu se weilei+silica gel of dilution 400 times; Mid or late June, when adult is out taken food with mating, manually flutter and catch.The American red-maple anoplophora glabripennis insect pest incidence processed is only 1.2%.

Example 2.

In late April, 2014, dilute 500 times of+20% Imidacloprid with 30% Phoxim microcapsule and dilute 500 times of filling roots; Mid-June, spray trunk in the tree above 100cm in body ground with the Lu se weilei+silica gel of dilution 400 times; Mid or late June, when adult is out taken food with mating, manually flutter and catch.The American red-maple anoplophora glabripennis insect pest incidence processed is lower than 2%.
