摘　　要：The pine sawfly (Acantholyda posticalis Matsumura) is a serious pest of Pinus sylvestris; P. tabulaeformis and P. koraiensis. Chemical control has been generally applied, but caused a lot of problems. We first found Formica fukaii (new record in China). The ants nesting on Carex sp. preying on pine sawflics is an important predator. When nests are removed on purpose, the ant's behavior is normal and the nest are expanded. It is a dominant species and a natural enemy of pine sawfly in Nehe County.The pine sawfly (Acantholyda posticalis Matsumura) is a serious pest of Pinus sylvestris; P. tabulaeformis and P. koraiensis.
