Abstract : Plastic McPhail Traps (PMT), placed in mango and guava trees in Ceára, Brazil during March 2001, were baited with the following attractants and lures: Nulure (NL), ammonium acetate (AA), putrescine (PT), trimethylamine (TMA), propylene glycol (PG), ammonium bicarbonate (AB), torula (T), Brazilian hydrolyzed protein (BHP) plus borax and the surfactant Triton to determine the most effective combinations of attractants that will lure fruit flies. The highest captures of female adults of Ceratitis capitata in mango and guava orchards were obtained from combinations of AA + PT + TMA + H2O and AA + PT + TMA + PG. The highest adult captures (5397 males and 5962 females) of Anastrepha spp. in guava orchards came from traps baited with NL + H2O. The best trap efficiencies for female adults of C. capitata were obtained by combinations of NL + H2O, AA + PT + TMA + Triton and AA + PT + TMA + PG. However, for Anastrepha spp. the best efficiencies came with NL. In mango orchards, the best combination for C. capitata was AA + PT + TMA and for Anastrepha spp. was AA + PT + TMA + PG. The treatment NL + H2O allowed the highest fly per trap per day (FTD) indices for both fruit flies.
