Fig. 1 in Area freedom in Mexico from Mediterranean fruit fly (Diptera: Tephritidae): a review of over 30 years of a successful containment program using an integrated area-wide SIT approach

Fig. 1. Schematic representation of the Pest Free Area (PFAs) in Mexico and in the Containment Barrier in Guatemala, with its 3 working areas: the Eradication or Low Pest Prevalence Area (LPA) (2a), the Suppression Area (2b) and the Monitoring Area (2c). The Mediterranean fruit fly pressure is from the east and the south toward the west and the north, with the leading edge of the pest population infestation located at some point within the suppression area along the 3 main infestation fronts as described in the text. The case is shown where the border between Mexico and Guatemala is the limit of the PFA; however, in years of high pest pressure the barrier was partially moved into the PFAs of Chiapas and Tabasco, while in favorable years the PFA in Guatemala grew an annual average of 20-30 km with the containment barrier being moved away from the Mexico-Guatemala border.
