Abstract: The bark beetle  Pityogenes scitus  Blandford was previously recorded from China (Tibet), Nepal, India and Pakistan, and its host plants included Cedrus deodara, Pinus wallichiana,  P. gerardiana , and  P. roxburghii . In Beijing, it invades the unhealthy stem and branches of the lacebark pine,  P. bungeana, as a new host plant. Heavy infestation causes the whole pine to death. It also invades healthy pines with high mortality. Here we described the diagnostic characteristics with color pictures provided, and proposed control strategies with emphasis on plant quarantine and promoting the health of the lacebark pine.

Key words: Pityogenes scitus, Pinus bungeana, morphology, diagnostic characteristics, control strategies
