Method for artificially propagating pyemotes bark beetle through Callosobruchus chinensis and application in biological control of bark beetle pests

Abstract

The invention discloses a method for artificially propagating pyemotes bark beetle and the application in biological control of bark beetle pests. The method for artificially propagating pyemotes bark beetle through Callosobruchus chinensis comprises the steps as follows: firstly, a host that is Callosobruchus chinensis is produced; secondly, protospecies of pyemotes bark beetle is prepared; and thirdly, pyemotes bark beetle is propagated. The method and the application have the benefits as follows: the difficult problem of propagating pyemotes bark beetle to replace the host is solved; pyemotes bark beetle can be propagated in large quantities; the method is simple and convenient to operate; large-scale production can be carried out; the method is applicable to control Scolytus seulensis Murayama pests on forests and fruit trees such as apricot trees, peach trees and plum trees; the problem that the forests and the fruit trees such as the apricot trees, the peach trees and the plum trees are damaged by the Scolytus seulensis Murayama pests and whole branches or entire trees die back further because the parasitism rate of pyemotes bark beetle is lower can be solved; therefore, the requirements of forestry and fruit Industry production can be satisfied, pollution on the environment cannot be caused, and the method is an effective technological means for controlling the Scolytus seulensis Murayama pests in an environmental protection manner.

Description

technical field [0001] The invention relates to a method for artificially multiplying the bark beetle mite and in the technical field of biological control of bark beetle pests, and relates to a method for artificially multiplying the bark beetle mite and its application in the biological control of bark beetle pests. Background technique [0002] hairy beetle ( Scolytus seulensis Murayama) belongs to the bark beetle family, and it occurs all over Xinjiang, especially in Aksu, Korla, Luntai County, and Kuqa County. Damage, hinder the transportation of water and nutrients, and eventually lead to dryness and death of whole branches or whole plants. Cause tree body grooming tissue to die. [0003] "Xinjiang Agricultural Science and Technology", 1993, (5): "The Occurrence and Comprehensive Control Techniques of the Hairy Beetle" published by Li Zhong et al. on pages 215 to 216 made the following report: Kuqa, Shaya, and Xinhe in the Aksu area of ​​Xinjiang have occurred. 4...

Problems solved by technology

[0008] The present invention provides a method of using mung bean elephants to artificially multiply the bark mite. The problem

[0009] The present invention also provides a kind of use mung bean elephant to artificially multiply the application of bark beetle mites in bark beetle pest biological control, overcomes the deficiencies in the prior art, Solve the problem that the low parasitic rate of bark beetle mites causes fruit trees such as apricots, peaches, and plums to be harmed by bark beetle pests, making the pruning or the whole plant dry and dead
