The aim of this study was to analyze the entomofauna diversity found in the orchard of fruit trees, in function of different techniques to capture, in Southern Brazil. Three traps were used for insect collection, hunting-fly, colored tray technique and pitfall. Were choose the follow fruit trees: Citrus sinensis, Ficus carica, and Rubus fruticosus. An abundance of 12,943 individuals was recorded, distributed in nine orders and 46 families. The most abundant orders were Diptera (60.07%), Coleoptera (31.07%) and Hymenoptera (7.47%). Considering the diversity index in function of the traps, there were a bigger diversity on the trays (H= 0.9454) than on pitfall (H=0.7788) and hunting-fly traps (H=0.6306). That occurs due, possibly, a smaller dominance in the trays. Each method considers an insect behavior, of feed or of locomotion, and complete each other to a realistic assessment in a fruit trees orchard.
