Method of preventing and treating red fat large small moth

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...

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
