The Pinus sylvestris var.mongolica forest of Honghuaerji Forestry Bureau is the only natural forest provenance base of Pinus sylvestris var.mongolica in sandy land in China.In recent years,Pinus sylvestris var.mongolica diseases and insect pests have been seriously damaged,and the tree strength of pure Pinus sylvestris var.mongolica forest has weakened.The species of longicorn beetle have increased.In this paper,the species and harm of Pinus sylvestris var.mongolica and longicorn beetle in Honghuaerji Forestry Bureau were investigated by manual investigation and hanging trap.The research shows that there are 6 species of longicorn beetle that endanger Pinus sylvestris var.mongolica in Honghuaerji Forestry Bureau,and the most serious harm is Monochamus saltuarius.From 2021 to 2023,the total number of traps was 3 773,accounting for 62.49％of the total number of traps,which is moderate hazard.In view of the fact that Monochamus saltuarius is the vector insect of pine wood nematode disease,it is necessary to closely monitor the insect situation,strengthen the control and effectively control its large-scale occurrence.
