The African citrus psyllid, (Del Guercio) (Hemiptera: Triozidae), is a vector of Liberibacter africanus (CLaf), a pathogen that causes huanglongbing (HLB) in Africa. has invaded areas of Asia and Europe and has threatened citrus production due to its biological habits and the transmission of CLaf. Mexico is a country where citrus production has a vital role from the economic and social point of view. Therefore, ecological niche modeling (ENM) was used to determine if Mexico has the environmental availability that will allow invasion. We analyzed whether or not the distribution of La Llave (Rutaceae) in the country could be a factor that enables the dispersal of . The environmental connectivity between five points of entry into the country (two ports and three airports) was explored to determine possible routes of dispersal of . The results showed that Mexico has wide availability for the invasion of the African citrus psyllid, which coincides with essential citrus areas of the country and with the distribution of . Of the entry points studied, the Port of Veracruz showed nearby areas with environmental connectivity. Preventive monitoring measures for in Mexico should focus on Veracruz state because it has an entry point, ideal environmental availability, citrus areas, and specimens of .
非洲柑橘木虱（Diaphorina citri Kuwayama）（半翅目：木虱科）是非洲韧皮杆菌（Candidatus Liberibacter africanus，CLaf）的传播媒介，该病原体在非洲引发黄龙病（HLB）。非洲柑橘木虱已入侵亚洲和欧洲部分地区，因其生物学特性及CLaf传播而对柑橘生产构成威胁。墨西哥从经济和社会角度看，柑橘生产至关重要。因此，利用生态位建模（ENM）来确定墨西哥是否具备允许非洲柑橘木虱入侵的环境条件。我们分析了该国莱檬（Citrus aurantifolia (Christm.) Swingle）（芸香科）的分布是否可能成为非洲柑橘木虱扩散的一个因素。探讨了该国五个入境点（两个港口和三个机场）之间的环境连通性，以确定非洲柑橘木虱可能的扩散路线。结果表明，墨西哥对于非洲柑橘木虱的入侵具有广泛的适宜性，这与该国重要的柑橘产区以及莱檬的分布相吻合。在所研究的入境点中，韦拉克鲁斯港附近区域显示出环境连通性。墨西哥针对非洲柑橘木虱的预防性监测措施应聚焦于韦拉克鲁斯州，因为该州有一个入境点、理想的环境适宜性、柑橘产区以及非洲柑橘木虱样本。
