1 According to the ecology behavior of polar longicorn, this paper puts forward the prevention principle and countermeasures.

2 The growth and development of longicorn larvae were obviously affected by different tree species.

3 Longicorn beetles are a group of important pests of forest, ornamental and fruit trees.

4 The spread of the disaster caused by longicorn beetle has not only endangered forestry,[] but also become a menace to the Yellow River agriculture which largely depends on ecological environment.

5 After being processed, rusty pine longicorn beetle and pine wood nematode in infected wood could be killed 100%, which meets the corresponding requirements of the national standard.

6 Carry on research to 11 kinds of longicorn beetles by two molecular marking techniques (RAPD, ITS-2).

7 The damages to mulberry trees caused by main longicorn beetles were summarized and some solutions were introduced.

8 The design of the test was directed against the serious harm which longicorn is doing to populous planted in Poyang Lake.

9 The experiment aims to investigate the occurrence and harm of longicorn (Anoplophora chinensis Forster ) to orange orchards, and to find out the methods of controlling longicorn.

10 In addition, S. guani could form field population in the poplar forest after it was released. Poplar longicorn was also sustained.
