Invasive mosquito species play an important role in transmitting pathogens that cause diseases in humans and animals around the world. In the last decade, arboviral pathogens transmitted by invasive mosquito species have increased substantially in the southeastern region of the USA ("the Southeast"). Early detection of invasive mosquitoes is an important component of an integrated mosquito management (IMM) plan. To determine the capacity of the southern region of the USA to conduct invasive mosquito surveillance, the Mosquito Biodiversity Enhancement and Control of Non-native Species (BEACONS) working group conducted a survey in 2021 in seven US southern states: Alabama, Florida, Georgia, Louisiana, Mississippi, North Carolina, and South Carolina. A total of 348 mosquito control agencies were contacted, and of those, 90 agencies (26%) responded. Here we report the results about the status of an IMM program and the techniques used for mosquito and pathogen surveillance in the Southeast. Results reveal several gaps in surveillance for invasive mosquito species, compromising the ability for early detection and rapid response. Further, we identified a lack of arbovirus testing, which could result in inadequate arboviral risk assessment and may increase the risk of human and livestock to acquire arboviral infections. This survey data can assist decision makers at the county, regional, and state levels to ameliorate gaps in surveillance capacity in the Southeast.
