Abstract
The fruit fly Anastrepha fraterculus is considered the main pest of fruit trees, including feijoa, Acca sellowiana, in the southern region of Brazil. The aim of this study was to evaluate the effect of Carapa guianensis on A. fraterculus. The research was carried out in a feijoa orchard in Lages, State of Santa Catarina, from December 2009 to December 2010. The experimental design was of randomized blocks with four repetitions. The treatments consisted of andiroba oil at 0.5, 1% and 2%, associated with 5% hydrolyzed protein (Bioanastrepha�), which was also used alone as control. Andiroba oil at 1% and 2% reduced the attractive potential of hydrolyzed protein; also, fewer females were captured in these two treatments.
