Method for breeding pyemote, and its culturing vessel, and method for releasing same

Abstract

A method for reproducing pyrmotide includes such steps as buying the developed pyrmotides, storing in cold storage case at -5-15 deg.C, choosing the bee larva, silkworm pupa, or grub as host, putting it in the internal plastic culture utensil, preferably selecting seed pyrmotide, inoculating it to said host, and test tube culture to obtain the second generation pyrmotide. It culture device is composed of a culture tray made of stainless steel and several pairs of internal and external culture utensils. A method for releasing the pyrmotides features that the cultured pyrmotides are loaded from test tubes to an open release box.

Description

technical field [0001] The invention relates to a breeding method of the cat mite, a cultivator thereof and a release method of the cat mite. technical background [0002] Stem borer is a forest pest that seriously harms forest plants and threatens forest ecological security. Outbreaks of borer pests often kill large areas of the forest. The stem borer pest lives in seclusion, and in its entire life generation, most of the time is harmed in the trunk or roots of the host, and the control method of ordinary spraying pesticides has almost no effect on it. Therefore, the prevention and control of borer pests is not only very difficult, the control cost is very high, and the control effect is not ideal, but also a large amount of chemical pesticides will cause serious environmental pollution. The use of natural enemies to control borer pests is the development direction of biological control, and it is also the key to sustainable, stable and effective control of forestry pests...

AI Technical Summary

Problems solved by technology

At present, there is a large-scale breeding method in China. This method adopts the following alternative hosts to breed cat mites, all of which have disadvantages: adopting the larvae of Cyperus chinensis to breed cat mites requires a large number of natural parasitic larvae of Cyperus chinensis, This is not only greatly affected by natural conditions, but also the number of larvae provided by nature cannot meet the requirements, and the source of insects cannot be guaranteed

Applying repellent is time-consuming and labor-intensive, not suitable for industrial production and application

[0004] The existing method of releasing the mites is to hang the test tube containing the mites on the tree trunk. Because the mites have the habit of climbing up, the opening of the test tube is inclined upwards, so that the mites are all at the bottom, which is not conducive to the mites quickly climbing out to find the host; The mouth of the test tube is upward, and once it rains, the rain will pour into the test tube and drown the mites; at the same time, some natural enemies of the mites will climb into the test tube to feed on the mites, which will affect the control effect

When it is necessary to repeat the prevention and treatment, it is necessary to hang the test tube again, so that the prevention and treatment is lower
