The cultivation of pejibaye (Bactris gasipaes Kunth) has been expanding in Brazil, especially in the Vale do Ribeira, SP, where the edaphoclimatic condition is compatible with its production. With the purpose of learning about insects that visit the inflorescence of pejibaye, a survey was conducted at Polo Regional do Vale do Ribeira, located in the municipality of Pariquera-açu, SP, Brazil, and on a private property located in the municipality of Registro, SP, areas where selected pejibaye palm trees from Yurimaguas, Peru, are grown. During the month of January of 2006 and 2007, yellow sticky insect traps were placed at the inflorescences of different pejibaye matrices, soon after the bracts opened. The traps were kept throughout female and male anthesis, and removed at the end of the cycle, which lasted for about 72 hours. The 9,743 insects collected were then separated, counted, and identified according to their orders. It was observed that the most frequent insects on the inflorescence of pejibaye palms in the Vale do Ribeira, SP are Diptera, Coleoptera, and Hymenoptera.
