Efficient trapping systems for Anastrepha spp is an essential requirement for integrated fruit fly management. In order to find more efficient attractants for this genus, food-based attractants were tested in two orchards in Colombia against A. obliqua, A. striata and A. fraterculus populations. Six experiments were carried out from 2001 to 2004, four of them were done in a mango orchard and the other two in a coffee plantation. The synthetic food attractants tested were different combination of Ammonium Acetate (AA), Putrescine (PT), Ammonium Bicarbonate (AB) and Trimethylamine (TMA); the controls were NuLure and Torula. Attractants were placed in Multilure traps using equidistant spacing of 28 m. Trap catches were recorded twice per week for a total of eight weeks. Traps were serviced once per week and rotated after each service. The experimental design was random blocks with five repetitions. In experiments 1, 2, 3, 5 and 6, NuLure and Torula were statistically the best attractants, however, synthetic lures caught more flies than the controls in the fourth one, when climate was hot and dry: 1/2AA+PT, 1/2AB+PT and 1/4AB+PT were the best attractant for males of A. obliqua and 1/2AA+PT and 1/4AB+PT were the best for females. In some repetitions the synthetic lures capture more or equal numbers of flies than the controls, perhaps when in the previous days the weather was hot and dry. Attractants in general caught a larger number of old females than young or mature females in the first tests, but the mature females were predominant in the fourth one when the synthetic attractants showed to be better. Fruit flies showed different response to attractants depending on sex, species and climatic conditions. More studies are needed in order to improve trapping systems for Anastrepha. (author)
