Embodiment Construction

[0028] The present invention will be further described in detail through specific embodiments below.

[0029] The method of the present invention is used to prevent and control the ornamental Erythrina japonica that has been infested by Erythrina japonicus in a certain scenic spot in Shenzhen and produces a large number of galls. The specific steps are as follows:

[0030] 1. Dig the topsoil layer at the base of the erythrina tree to a depth of 15cm to 20cm;

[0031] 2. Use a chisel to shovel off the uneven old bark on the surface of the tree base near the root after excavating the topsoil layer, and the width of the shovel is about 15cm;

[0032] 3. Wrap the base of the Erythrina tree trunk after eradicating the old bark with a sponge block. The specification of the sponge block: width 10cm×thickness 1cm×length, the length depends on the thickness of the trunk, which is the length of a circle around the trunk;

[0033] 4. The sponge block is wrapped with a 0.14mm thick polyv...

Abstract

A method for preventing and controlling the tiny ichneumon fly of erythrina tree includes removing the old bark from the root part on the trunk of erythrina tree, binding the hydroscopic material to the positions where the old bark has been removed, and injecting the agriculture chemical into said hydroscopic material.

Description

technical field [0001] The invention relates to a method for controlling insect pests, in particular to a method for controlling Erythrina chinensis. Background technique [0002] In July 2005, a certain scenic spot in Shenzhen suffered serious insect damage to ornamental Erythrina. After investigation, it was found that there were a large number of galls on the Erythrina tree, and the damage was extremely serious. After taking the samples back to the room for breeding, a total of 362 adult parasitic wasps emerged. It was identified as Quadrastichus erythrinae Kim. [0003] Erythrina is a new species published in 2004, currently only reported in Mauritius, Reunion in Africa, Singapore, Taiwan in Asia, and Hawaii in the United States. There is no distribution record in my country, and it is a new record species. After the discovery of the Erythrina spp. epidemic, the General Administration of Quality Supervision, Inspection and Quarantine, the State Forestry Administration...
