Analysis of Diversity of Pest Species of Anastrepha in ‘Barranqueño’ Mango (Mangifera indica L.)

Abstract. Alpha and beta diversity of Anastrepha spp. fruit flies in orchards of creole ‘Barranqueño’ mango (Mangifera indica L.) at Amatitán, Tequila, and San Cristóbal de la Barranca municipalities (Jalisco, Mexico) were analyzed. Eighty-two Multilure traps were set up to catch specimens from May to October 2021. The traps were at Amatitán (12), Tequila (12), and San Cristóbal de la Barranca (18) where altitude and temperature variables also were recorded. Alpha diversity (Hill numbers) and beta diversity (βSOR) were analyzed for each component. In total, 21,708 specimens of four species were captured: A. ludens (93.09%), A. serpentina (5.79%), A. obliqua (1.02%), and A. striata (0.09%). Richness of flies between Barranqueño mango orchards might be the same or similar, but diversity and equity of the assemblage differed in each orchard. There was less spatial rotation of Anastrepha species in the orchards. Diversity of flies in Barranqueño mango orchards was related to agroclimatic factors, crop phenology, altitude of the study area, and other pest hosts.
