Abstract : The tephritids of the genus Anastrepha and Ceratitis capitata are economically important pests that occur in Brazil and other countries. The identification of the species is fundamental for management, mainly in areas responsible for fruit production. A study was carried out between January and March 2006 to evaluate food baits to monitor fruit fly populations and to provide knowledge associated to host range in the municipality of Ilhéus, Bahia. Fruits were randomly collected in urban and rural areas and transferred to plastic cups with substrate to promote larval pupation. The pupa were collected and placed in plastic cups with substrate until adult emergence. McPhail traps using 5% hydrolysed protein (BioAnastrepha) and Torula were used as baits. The insects captured in the traps were collected and brought to the laboratory weekly and the bait was changed every 15 days. The main fruiting trees sampled were: abiu (Pouteria caimito, Oxalidaceae), guava (Psidium guajava, Myrtaceae), water apple (Syzygium malaccense, Myrtaceae) and mango (Mangifera indica, Anacardiaceae). Five species from the Anastrepha genus were collected: A. fraterculus, A. obliqua, A. serpentina, A. pseudoparallela and A. distincta, as well as C. capitata. A. fraterculus, A. obliqua, A. serpentina and A. sororcula emerged from the sampled fruits. C. capitata occurred mainly in the urban zone and the species of Anastrepha in the rural areas. The food baits were efficient to capture fruit flies.
