Problems solved by technology

Since our country is far away from Europe, if we directly purchase the biological control of the red beetle beetle for our country, the cost will be too high, and because the adult beetle beetle is a living body, a certain number of natural enemies will die during the long-distance transportation. Every purchase must go through the quarantine procedures of the customs of both sides, which has greatly increased the cost of our country's direct purchase of natural enemies from Belgium

Embodiment 1

[0032] Embodiment 1, the artificial large-scale propagation and release of Derma chinensis

[0033] (1) Propagation: room temperature is 20±2°C, humidity is 70±5%:

[0034] 1) Raising of adults: put 2 / 3 of the sawdust in a circular culture box made of polypropylene material (the box body is shown in Figure 1, the diameter is 65mm, the depth is 17mm, and the depth of the box cover matched with it is 23mm) , The sawdust is mixed with distilled water, and the humidity is preferably such that no water droplets can be squeezed out by hand. Put 10-15 large red beetle larvae or 20-30 small larvae in the sawdust, then place 10 adult beetles ♀ and ♂ adults, and then cut a piece with an area slightly smaller than the box. Chinese pine bark (the bark is required to have a phloem), the phloem covers the sawdust downwards, then covers the box and puts it in a dark place. Adults will feed on beetle larvae and lay eggs. The eggs are long oval, and the egg period is about 6 days.

Embodiment 2

[0039] Embodiment 2, invention effect investigation

[0040] Shanxi Province is the hometown of Pinus tabulaeformis, and it is also the most severely damaged by the red fat beetle. In late July 2002, we released 1,000 adult beetles we raised artificially in the Lingkong Mountain Forest Farm of Taiyue Forestry Bureau, Qinyuan County, Shanxi Province, where the red beetle was seriously infested, and carried out a control test. The area of ​​the test area is 33 hectares, and most of the Chinese pine trees are over 20 years old. 40 days after the release, the control effect inspection was carried out at the place of release. After dissecting the trees, it was found that the adult beetles had entered the tunnels eaten by the red beetle under the bark of the Chinese pine tree, and had eaten up all the small larvae of the beetle. In July 2003, we carried out the second inspection of the control effect, and found that the red beetle beetle could not be found in the forest land where...

Abstract

A method for artificially reproducing a lot of a kind of beetles and releasing it for preventing and controlling a kind of tree moth includes reproducing the beetles through culturing adults, culturing larvas, pupating and low-temp naturalization of adults, and releasing the female and male beetles onto host tree.

Description

technical field [0001] The invention relates to a method for preventing and controlling the red beetle, in particular to a new technology for using predatory natural enemy insects to biologically control foreign invasive forestry pests—the red beetle, and belongs to the field of biological control. technical background [0002] The red beetle is a major forestry pest that was introduced into my country from the United States with imported logs in the 1980s. It mainly damages Chinese pine (Pinus tabulaeformis Carr.) and other pine trees. Because the red fat beetle harms healthy Chinese pine, especially Chinese pine plants that are more than 30 years old and in the peak growth period, the losses caused are very serious. In 1999 alone, 3.516 million Chinese pine trees were killed in Shanxi Province, and the damaged area was 3.71 million mu. By 2002, the national affected area had reached 7.02 million mu. The damage characteristic of the red beetle is that it lives in seclusio...
