摘　　要：木蠹象Pissodes spp.主要危害松科植物,但大多数种类的寄主范围相对较窄,较少跨属危害;该虫可致木材生产量降低、材质变劣,甚至全株死亡,有些种类还可能传播林木病害;大多数种类1a发生1代,但成虫期及产卵期长,世代重叠现象明显;不同种类在不同寄主植物、地理环境及林分条件下,发生发展及危害程度都有可能不同。对该虫的治理策略包括预防监测、人工清除、物理捕杀、药剂防治、营林管理、天敌保护及利用、害虫诱捕及检疫等,今后在实践中要加强害虫防治新技术新方法的研究及推广。Pine weevils （Pissodes spp. ） were a group of pests mainly damaging pines. Most of them had relative narrow range of hosts （ within a single genus）. They could decrease the tree growth, lower the wood quality or even cause the death of the whole plant. Some species might act as the vectors of certain important forest diseases. Most weevils had one generation a year and the generations overlapped due to the long life span and oviposition period of adults ; The occurrence and damage severity of differ- ent species on different host plants under different geographic environments and stand conditions were usually different. Management strategies for pine weevils included preventive monitoring, artificial cleaning, physical killing; chemical control; silvicultural management, protection and utilization of natu- ral enemies, pest attraction, and plant quarantine and so on. In the future, new control techniques and methods should be found in practice.
