Description Phthorimaea absoluta is a species of moth known for its impact on tomato plants. It is devastating totomatoes, attacking mainly the leaves, stems, flowers and fruits of tomato plants, and can cause up to 100% damage. Understanding its potential distribution is crucial for pest management and control. The CLIMEX version 4.0, was used to analyze the current global distribution of P. absoluta. It identifies regions or areas where the climatic conditions are suitable for the pest survival and reproduction. In addition to current distribution, the model can also be used to project the potential future distribution of P. absoluta by using RCP 8.5 climate change scenario. This is especially valuable for understanding how climate change may affect the range and abundance of the species. Here, we predicted the P.absoluta geographic distribution on a global scale. This study projects the areas that will be attacked by this bug both now and in the future using a combination of spatial distribution models and the pests existing distribution. Based on the pests thermal requirements and the stress factors that restrict it, we estimated the pests possible range. The model presented here showed large suitable regions for the P. absoluta in the North and Central Americas, Africa, Europe, Asia and Oceania for the current and future times. These forecasts will contribute to understanding of how climate change may affect  P. absoluta possible global distribution and, consequently, offer a theoretical framework for the creation of early detection, quarantine, and control measures.
