Three panel pathway map illustrating seasonal Mediterranean fruit fly environmental suitability, Mediterranean fruit fly occurrence risk at origin airports, and predicted passenger flow to California during 2010. The passenger number was obtained from vbd-air.com (Mao et al. 2015) and adjusted (weighted) for risk of Mediterranean fruit fly occurrence. Mediterranean fruit fly presence or absence was designated according to the European and Mediterranean Plant Protection Organization and International Atomic Energy Agency (EPPO 2009, IAEA 2013b). Mediterranean fruit fly seasonal suitability maps were derived from Szyniszewska and Tatem (2014).
