(Lamiales: Oleaceae)), causing economic losses worldwide. The pest has been detected in the United States and Mexico, showing potential to invade new areas. Among the parasitoids used to control B. oleae, Fopius arisanus (Sonan, 1932) and Psyttalia concolor (Szépligeti, 1910) (Hymenoptera: Braconidae) are considered cenobiont and sinovigene endoparasitoids. Through the study of the potential geographic distributions, the size of regions environmentally suitable for the species can be understood, and the areas of distribution of the pest can be related with those of the parasitoids, with the goal to estimate whether the parasitoids would be suitable for use in classic biological control. The aim of this study was to map the potential global distribution regions, with an emphasis on South America, of B. oleae and the two parasitoids F. arisanus and P. concolor and show the overlap of geographically environmentally adequate areas for the joint establishment of the pest and natural enemy. For map the potential global distribution regions, a predictive model correlative of the distribution of the species was used, generated from known data of...
