a International Air Transport Association (IATA) airport codes: GRU (Brazil), CCS (Venezuela), LIM (Peru), EZE (Argentina), BOG (Colombia), SJO (Costa Rica), MDE (Colombia), PTY (Panama), CDG (France), SAL (El Salvador), ZRH (Switzerland), MIA (Miami), FLL (Fort Lauderdale), MCO (Orlando), LAX (Los Angeles), and SFO (San Francisco). Origin–destination airports were selected based on the highest number of passengers arriving to Florida and California.
b The seasonal risk of Mediterranean fruit fly abundance at departing flight locations was derived from the Mediterranean fruit fly environmental suitability model (Szyniszewska and Tatem 2014) and classified as high (1.0), medium (0.6), or low (0.2).
c The estimated seasonal number of passengers departing on direct flights from international airports in Mediterranean fruit fly-infested countries and arriving in Florida and California was derived from the open-access passenger flow model for 2010, Vbd-air.com (Mao et al. 2015).
d The annual risk indicators for paired origin–destination airports (AORIijk) were derived by multiplying the risk of Mediterranean fruit fly occurring at the departing flight location (low = 0.2, medium = 0.6, and high = 1.0) in each season by the estimated number of passengers on the route and dividing the product by the total number of seasonal passengers on the route. Higher AORIijk scores indicate greater annual risk of Mediterranean fruit fly arrival relative to the total estimated number of passengers.
