Epiphyas postvittana, commonly known as the light brown apple moth (LBAM), is native to Australia and has a restricted global distribution. Its polyphagous nature recent surge in interceptions have emphasized need for focused risk assessments guide effective measures curb entry of this pest into new countries. This study aimed perform detailed invasion assessment using an optimized MaxEnt model that incorporated 19 bioclimatic variables elevation. The predictive outcomes underscored significance key variables, specifically minimum temperature coldest month (bio6), precipitation driest (bio14), quarter (bio19), shaping potential geographical distribution LBAM. Regions beyond existing range, including southeastern United States, southern Brazil, eastern Argentina, Uruguay, Chile, various Western European countries, were identified susceptible establishment by An increase suitability was observed above 45°N 40°S under future climate scenario.

ABSTRACT Climate change significantly contributes to shifts in the geographical range of pests and diseases. Leafhoppers (Hemiptera: Cicadellidae), known vectors phytoplasmas pathogens, are linked transmission more than 600 diseases affecting a thousand plant species worldwide. Despite this, potential effects climate on leafhopper remain critical knowledge gap. To address this gap, our study investigated impact 14 Nearctic leafhoppers previously associated with phytoplasma-related Using MaxEnt distribution algorithm other ecological niche modeling techniques, we assessed (i) expected richness under current conditions four future scenarios (ii) environmental similarity among these across scenarios. Our projections suggest that eastern region North America holds for highest richness, trend persist all scenarios, gradually expanding eastward. Notably, findings indicate increasing suitability northern Canada species. Network analysis further revealed remarkable niches most Moreover, there is tendency an increase similarity. Altogether, underscores persistent presence their habitats while pointing shift toward These have significant implications sustainable pest management practices, prompting necessary discussion strategies mitigate migration’s agricultural systems.
