Hylurgus ligniperda (Fabricius) is an important pest that attacks Pinus species in China. It impacts the vitality of local pine vegetation, reduces the ability to prevent windbreak and sand fixation, and causes ecological loss. MaxEnt and ArcGIS are used to predict and analyze the changes in suitable distribution areas of H. ligniperda under current and future climate scenarios, based on 12 climate factor datasets and 1,001 field distribution data points for this pest. The environmental variables used significantly influence the potential distribution of H. ligniperda. Highly suitable areas of this beetle are located in western Europe, central Asia, and the southeastern regions of Oceania, with sporadic occurrences across North America, South America, and Africa. Highly suitable areas in China occur across the east, central south, and southwest regions. There is a significant increase in the high and medium suitability areas, while the area of low suitability decreases under the 4 future climate scenarios (SSP126, SSP245, SSP370, and SSP585). The suitable distribution area for H. ligniperda shows an overall trend of moving northwestward. The purpose of this current study is to provide important theoretical support for the prevention and management of this pest by predicting and analyzing suitable distribution areas under current and future climate scenarios.
松墨天牛（Hylurgus ligniperda (Fabricius)）是一种在中国危害松属植物的重要害虫。它影响当地松树植被的活力，降低防风固沙能力，并造成生态损失。基于12个气候因子数据集和该害虫的1001个野外分布数据点，利用最大熵模型（MaxEnt）和ArcGIS预测和分析了松墨天牛在当前和未来气候情景下适宜分布区的变化。所使用的环境变量对松墨天牛的潜在分布有显著影响。这种甲虫的高度适宜区位于西欧、中亚和大洋洲东南部，在北美洲、南美洲和非洲有零星分布。在中国，高度适宜区分布在东部、中南和西南地区。在4种未来气候情景（SSP126、SSP245、SSP370和SSP585）下，中高适宜区面积显著增加，低适宜区面积减少。松墨天牛的适宜分布区总体呈向西北移动的趋势。本研究的目的是通过预测和分析当前和未来气候情景下的适宜分布区，为该害虫的预防和管理提供重要的理论支持。
