The spread of pest insect species poses major challenges to agriculture, forestry, and biodiversity. The Food and Agriculture Organization of the United Nations estimates that pests cause 20–40% of global crop losses annually, valued at over $290 billion. To
mitigate these losses, understanding where these pests might spread—especially in response to climate change—is crucial for proactive management and food security.</div>

Species distribution modeling (SDM) is a powerful tool for predicting where species are likely to thrive. One widely used method is Maxent, a machine learning-based ecological model. In this talk, I will present a study that predicts suitable habitats for three
key pest insect species in the continental United States:</div>
