| Latin Name | Polygraphus proximus | 
| Common Name | Siberian four-eyed spruce bark beetle | 
| Biology | Coleoptera (Curculionidae, Scolytinae); similar to P. subopacus; infests conifers (e.g., spruces); larvae develop in phloem galleries.  | 
                                
| Damage | Causes phloem damage, weakening trees; contributes to forest decline in coniferous stands.  | 
                                
| Distribution Regions | Eastern Europe, Asia (e.g., Russia, Northeast China, Korea).  | 
                                
| Monitoring | Trapping with aggregation pheromones; surveys of stressed conifers.  | 
                                
| Recommended Traps | Multiple-funnel traps or sticky traps with species-specific pheromones.  |
