Colorado Potato Beetle (CPB) is a devastating invasive pest of potato both in its native North America and now across Eurasia. It also damages eggplant, tomato and feeds on several wild species in the Solanaceae, such as S. eleagnifolium and S. rostratum Dunal (SR). Since first categorized as a pest in 1864, CPB has spread rapidly across North America, Europe and Asia. In light of its invasiveness and economic importance, it is necessary to study how climate change and host availability may alter the distribution of the CPB. Maximum Entropy (MaxEnt) models were used to anticipate global range expansion as influenced by environmental conditions, and by the possibility of cooperative invasion of CPB and its wild host SR. The results indicate that both CPB and SR can occupy warm areas of North America, South Africa, Europe, China, and Australia. Future climate conditions may promote CPB expansion into northern regions and SR into the circumpolar latitudes. The existing range and continued spread of SR may also assist the global expansion of CPB. Future management of this pest should consider the impacts of global climate change and host availability on its potential global distribution.
科罗拉多马铃薯甲虫（CPB）是一种破坏性的马铃薯入侵害虫，原产于北美的马铃薯，现在已遍布欧亚大陆。它还会损害茄子、番茄，并以茄科中的几种野生物种为食，如 S.eleagnifolium 和 S.rostratum Dunal（SR）。自 1864 年首次被归类为害虫以来，CPB 已迅速在北美、欧洲和亚洲传播。鉴于其入侵性和经济重要性，有必要研究气候变化和寄主可用性如何改变 CPB 的分布。最大熵（MaxEnt）模型用于预测环境条件和 CPB 及其野生宿主 SR 合作入侵的可能性对全球范围扩大的影响。结果表明，CPB 和 SR 都可以占据北美、南非、欧洲、中国和澳大利亚的温暖地区。未来的气候条件可能会促进 CPB 向北部地区扩张，SR 向极地纬度扩张。SR 的现有范围和持续传播也可能有助于 CPB 的全球扩张。未来对这种害虫的管理应考虑全球气候变化和寄主可用性对其潜在全球分布的影响。
