Abstract : The objective of this research was to know the species and the population fluctuation of fruit flies (Diptera: Tephritidae) in a commercial mango (Mangifera indica L.) orchard in the coast of Ceará State. The study was developed from July of 2005 to July of 2007, in the municipality of Beberibe (CE). The capture of the fruit flies was performed using McPhail traps with 5% corn protein hydrolyzed solution as attractant. Weekly, the captured insects were sorted, the fruit flies were maintained in 70% alcohol solution and subsequently identified. The population fluctuation was estimated using the FTD (Fly/Trap/Day) index. During the research, six fruit flies species were captured: Anastrepha obliqua (Macquart) (63%), A. zenildae Zucchi (7%), A. sororcula Zucchi (5%), A. fraterculus (Wied.) (2%), A. distincta Greene (2%) and Ceratitis capitata (Wied.) (21%). The Anastrepha spp. and C. capitata population peaked was between April and July, in both years of study.
