^a International Air Transport Association (IATA) airport codes: MIA (Miami), FLL (Fort Lauderdale), MCO (Orlando), LAX (Los Angeles), and SFO (San Francisco).

^b The adjusted total passenger number was derived by summing the products of the estimated number of passengers arriving from Mediterranean fruit fly-infested countries multiplied by the seasonal risk (ARI_ij) of Mediterranean fruit fly occurrence at a departing flight location.

^c An arrival risk ratio was derived for each destination airport by summing the risk-adjusted number of passengers arriving each season from Mediterranean fruit fly-infested locations and dividing the sum by the total of all passengers that arrived on international flights.

^d Risk indicators (ARI_ij) were derived by multiplying the risk of Mediterranean fruit fly occurring at the departing flight location in each season by the estimated number of passengers on the route and dividing the product by the estimated total number of seasonal passengers on the route. Higher ARI_ij scores indicate greater annual risk of Mediterranean fruit fly arrival relative to the total estimated passenger number.

^e The estimated number of passengers arriving at Florida and California on direct flights from all and Mediterranean fruit fly-infested countries was derived from the open-access passenger flow model for 2010, Vbd-air.com (Mao et al. 2015).
