摘要: 本文描述了北京白皮松上一种新的重要蛀干害虫——品穴星坑小蠹 Pityogenes scitus  Blandford,它分布于我国西藏、尼泊尔、印度和巴基斯坦,寄主植物为雪松、乔松、西藏白皮松和西藏长叶松。在北京品穴星坑小蠹为害白皮松,成虫入侵生长不良的白皮松主干或枝条,大量小蠹的为害可致白皮松死亡;品穴星坑小蠹也可入侵健康的白皮松,但小蠹死亡率很高。本文提供了品穴星坑小蠹的鉴别特征,附有识别特征图,并依据生物学特性提出防治策略,重点在于植物检疫和提高白皮松的健康水平。

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 wallichianaP. 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
