Technology for artificial domestication and breeding of sclerodermus and applied to prevention and treatment of pine sawyer beetles

Abstract

The invention discloses a technology for artificial domestication and breeding of sclerodermus and applied to prevention and treatment of pine sawyer beetles. The technology for artificial domestication and breeding of sclerodermus comprises the following steps of: firstly, feeding the sclerodermus to be substituted for the host of a barley pest; secondly, carrying out the selecting and refrigerating treatment of female sclerodermus; thirdly, packing the initiated pupa barley pest and the female sclerodermus into a finger-shaped tube, and plugging the tube with an ordered pine plug; and finally, neatly stacking and placing the tubes into a weather cultivation box with a cultivation temperature and conditions as well as prompts. In a bursaphelench xylophilus epidemic area, the throwing technology of sclerodermus comprises the following steps of: firstly, setting bait woods to induce the pine sawyer beetles to lay eggs; then examining the parasitic situation of the pine sawyer beetles in a pine tree section in an appropriate weather condition, and releasing the sclerodermus according to the groove number of the sawyer beetles; and finally investigating the parasitic situation of the sclerodermus. By the adoption of sawyer pests to prevent and treat the pine sawyer beetles so as to inhibit the occurrence of a bursaphelench xylophilus disease, the environment can not be polluted, the ecological balance is maintained, the biological diversity is kept, and the technology is an advanced technology for controlling the pine sawyer beetles and the bursaphelench xylophilus disease.

Description

technical field [0001] The invention relates to a technology for biological control of pine wood nematode disease, in particular to a series of technologies for artificial domestication and breeding, and release of swollen beetles in epidemic areas. Background technique [0002] Pine wood nematode disease is a major and destructive disease of pine trees. It has strong pathogenicity, rapid host death and rapid spread. Once it occurs, it is difficult to control. It is known as the "AIDS" of pine trees. It not only causes huge losses to the national economy, but also destroys the natural landscape and ecological environment, posing a serious threat to my country's huge pine forest resources. However, the main way for pine wood nematode disease to spread in close range in nature is to rely on the insect Monochamus alternata as a medium. At present, the forestry industry agrees that the effective means to control pine wood nematode disease is to control the transmission vector o...

Problems solved by technology

[0005] The above-mentioned chemical control and other conventional control methods are difficult to effectively prevent and control the monochamus alternatus, and the large-scale use of chemical agents has seriously polluted the environment, and the gains outweigh the losses.
