摘　　要：对红脂大小蠹越冬部位及虫态,胁迫条件下的寄主、生活习性进行模拟试验,对各地红脂大小蠹的年生活史进行系统研究。结果显示,在我国红脂大小蠹各主要发生地,该害虫主要在油松伐桩、衰弱树和新死亡树的根部以大龄和老熟幼虫或少量成虫越冬。在山西、河北和河南、陕西的北部部分发生区,油松伐木树皮下也是红脂大小蠹的重要越冬场所之一,红脂大小蠹成虫还可以转主为害。林地火灾、割松脂作业过度和偷砍乱伐等人为不良因素干扰的林地,红脂大小蠹发生程度较重。做好林地的防火、防盗伐,合理的抚育是控制红脂大小蠹发生非常重要的措施。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.
