摘　　要：【目的】为明确辽宁省瓦房店市得利寺镇果园内蔷薇科果树上天牛的种类、危害特征和种群动态。【方法】采用笼养法和虫害木解析法进行研究。【结果】(1)共发现天牛8种,分别是家茸天牛Trichoferus campestris Faldermann、双隆短翅天牛Glaphyra kojimai Matsushita、多斑坡天牛Pterolophia multinotata Pic、拟蜡天牛Stenygrinum quadrinotatum Bates、樱桃虎天牛Chlorophorus diadema Motschulsky、桃红颈天牛Aromia bungii Faldermann、薄翅锯天牛Megopis sinica White和四点象天牛Mesosa myops Dalman。(2)桃红颈天牛为害果树活立木的主干;四点象天牛、樱桃虎天牛和多斑坡天牛主要为害衰弱的果树主干和树枝;薄翅锯天牛为害果树朽木;家茸天牛为害枯死的果树树干和树枝;双隆短翅天牛和拟蜡天牛为害细枝。(3)家茸天牛、双隆短翅天牛、多斑坡天牛、拟蜡天牛、桃红颈天牛和薄翅锯天牛一年中均有1个明显的羽化高峰,四点象天牛一年中有2个成虫出现高峰,樱桃虎天牛的羽化高峰不明显。【结论】不同果树上为害的天牛种类存在差异。8种天牛为害果树的健康程度存在差异,其中桃红颈天牛对果树的为害最严重。8种天牛的种群动态规律存在差异。[Objectives] To determine the species, damage and population dynamics of longicorn beetles （Cerambycidae） infesting Rosaceous fruit trees （Rosaceae） in an orchard in Delisi township, Wafangdian city, Liaoning Province. [Methods] Longicorn beetle larvae were reared in cages to adulthood and identified to the species level and the types of damage caused by different species was analyzed. [Results] （1） Eight species were identified; Trichoferus campestris Faldermann, Glaphyra kojimai Matsushita, Pterolophia multinotata Pic, Stenygrinum quadrinotatum Bates, Aloe bungii Faldermann, Megopis sinica White, and Mesos myops Dalman. （2） Aromia bungii commonly infested the main stem of trees, whereas Mesosa myops, Chlorophorus diadema and Pterolophia multinotata mainly infested weakened stems and branches. Megopis sinica mainly infested rotten trees and Trichoferus campestri infested withered trunks and branches. Glaphyra kojimai and Stenygrinum quadrinotatum mainly damaged slender branches. （3） Trichoferus campestris, Glaphyra kojimai, Pterolophia multinotata, Stenygrinum quadrinotatum, Aromia bungii and Megopis sinica each had one annual peak of emergence but Mesosa myops had two and Chlorophorus diadema had no obvious peak period of abundance. [Conclusion] The population dynamics of the eight species of beetle differed and different species infested different parts of fruit trees and caused differing degrees of damage to the health of infected trees. The most serious damage was caused by Aromia bungii.
