Potential Distribution of Aedes (Ochlerotatus) scapularis (Diptera: Culicidae): A Vector Mosquito New to the Florida Peninsula

Aedes scapularis is a neotropical mosquito known to transmit pathogens of medical and veterinary importance. Its recent establishment in southeastern Florida has potential public health implications. We used an ecological niche modeling approach predict the abiotic environmental suitability for Ae. across much Americas Caribbean Islands. Georeferenced occurrence data obtained from Global Biodiversity Inventory Facility collection records southern served as input model calibration. Environmental layers included bioclimatic variables provided 2000 2010 average Modern Era Retrospective-analysis Research Applications climatic (MERRAclim) data. Models were run software program Maxent. Isothermality values often found costal environments, had greatest contribution performance. Model projections suggested that there are areas predicted be suitable Scapularis portions Amazon Basin, Yucatán Peninsula, multiple Additionally, predictions connectivity highly or relatively environments spanning United States Gulf Coast, which may facilitate geographic expansion this species. At least sixteen counties scapularis, suggesting vigilance needed by vector control agencies recognize further spread vector.
