Biodiversity of fruit flies of the genus Anastrepha (Diptera, Tephritidae) at the ESALQ-USP campus, Piracicaba, São Paulo. The aim of this study was to determine the number of species of Anastrepha Schiner at the campus and to verify the association between host plant species and Anastrepha species in this area. A total of 23,277 females of Anastrepha collected in McPhail traps was examined, and 18 species belonging to nine species groups were recorded. A total of 563 fruit samples representing at least 23 plant species from nine families was collected in 47 capture sites. A total of 10,243 females was identified. Of the 18 Anastrepha species captured in traps, only six emerged from fruit samples: A. bistrigata Bezzi, A. fraterculus (Wied.), A. obliqua (Macquart), A. pseudoparallela (Loew), A. serpentina (Wied.) and A. sororcula Zucchi. A. fraterculus infested the greatest diversity of hosts. The preferred hosts of A. obliqua were plant species of the family Anacardiaceae. A. pseudoparallela, and A. serpentina only infested species of Passifloraceae and Sapotaceae, respectively. A. fraterculus is recorded for the first time in sapodilla (Manilkara zapota L.) in Brazil.
