Field evaluation of attractant substances on the catch of Anastrepha spp. (Diptera: Tephritidae), pest of fruit in tropical America. III. Borated hydrolysed protein and borated torula yeast.
McPhail traps were used in studies to evaluate the effectiveness of borated hydrolysed soya protein, borated torula yeast type B and S and an aqueous solution of borax for catching Anastrepha spp. in guava plantations in Costa Rica in 1987. Hydrolysed soya protein caught the highest proportion (49.3%) of adult flies in each sampling, followed by type B yeast (24.7%), type S Yeast (16.7%) and borax solution (9.3%). A total of 4 species of the genus Anastrepha were caught: A. striata (61.0%), A. serpentina (23.0%), A. obliqua (16%) and A. balloui (0.01%). Adults of Ceratitis capitata and Toxotrypana curvicauda were also caught.
