Abstract:

This paper investigated the biological characteristics and occuring law of Dendroctonus valens (Red Turpentine Beetle, RTB) in China. D. valens lived through the winters mainly at elder larvae and mature larvae stage under the roots of Pinus tabulaeformis stumps and weak trees in most of areas infested. The RTB adults were also able to over winter under the bark of P. tabulaeformis stocks in some areas of southern Shanxi, Henan, Hebei and Shaanxi Provinces. The RTB occurred for 1~2 generations in different regions. A RTB adult could probably transfer to attack other trees. Fired stands or
stands suffered wanton cutting were susceptible to infection by RTB.

Key words: Dendroctonus valens, biological characteristics, occurring law, exotic invasive pest, forestry pest
