Lycorma delicatula is a species native to the PR of China that has become invasive in South Korea, Japan, and the United States. It is considered a significant threat to agriculture, particularly the viticulture industry, and its further spread into new areas could exacerbate its economic impact. Species Distribution Models (SDMs) are commonly used to analyze the distribution of invasive species, and while L. delicatula has already been studied using this spatial modeling approach, previous research has mostly focused on the effects of bioclimatic variables, often overlooking the role of habitat characteristics, including the presence of host plants. In our study, to assess the presence of other suitable habitats for the species on a global scale, we developed a two-step SDM calibrated within its native range, within biogeographic barriers. In the first step, we built two separate models: one for habitat suitability (HSM), incorporating land cover, elevation, and host plants, and another for bioclimatic suitability (BSM). The HSM calibration included the allocation of a portion of pseudo-absences (PAs) along background points (BPs) to mitigate the sampling bias of occurrences concentrated in highly urbanized areas (one bias-controlled PA for every four random BPs). In contrast, the BSM calibration was performed using a fully random allocation of BPs. In the second step, the two models were combined to produce an overall suitability map for the native range, which demonstrated...
