Damaging Regularity of Red Turpentine Bark Beetle (Scolytidae: Dendroctonus valens Le Conte) In Northwest China
摘要
Abstract
Damaging regularities of the red turpentine bark beetle (Scolytidae: Dendroctonus valens Le Con-te) occurring in northwest China were studied. It was observed that the beetle only fed and damaged Chinese pine (Pinus tabulaeformis). The damages were more serious in pure Chinese pine forests than in mixed forests, including P. tabulaeformis with Betula platyphylla , Populus davidiana , Quercus liao-tungensis and shrubs. The damages in the forests located in low slope positions and valleys were more serious than those in the middle and up slopes, more serious in half-sunny slopes than in shade slopes. The damage degree in sunny slope was the least serious, and more serious in the forest edge and road side. The beetle was the most serious at the altitude above 1 500 m in Malan Mountains, and 1 100 to 1 300 m in Huanglong Mountain.关键词
