RESUMO:A pupunha (Bactris gasipaes) vem ganhando cada vez mais importância econômica para a região do Vale do Ribeira/SP. Poucos estudos são realizados com a cultura, porém sabe-se que um dos fatores limitantes ao seu cultivo esta associado à ocorrência de insetos praga, como a coleobroca Rhynchophorus palmarum. Suas larvas broqueiam o caule da planta podendo ocasionar perdas devido à redução do perfilhamento e abertura de ferimentos facilitando a ocorrência de doenças. Para o monitoramento de R. palmarum pode-se utilizar armadilhas do tipo balde contendo atrativos alimentares e feromônio sintético. O presente estudo visou avaliar diferentes atrativos em armadilhas tipo balde sobre a captura de adultos de R. palmarum. Foram testados cinco tratamentos compondo diferentes combinações de atrativos: feromônio, feromônio + toletes de cana-de-açúcar, toletes de cana-de-açúcar, feromônio + resíduo de pupunheira e resíduo de pupunheira somente. As armadilhas foram rotacionadas em cinco pontos da arena montada no campo. Por meio de avaliações semanais observou-se que o tratamento contendo resíduo de pupunha + feromônio foi o mais atrativo a broca. Palavras-chave:Feromônio. Coleta missal. Amostragem. EVALUATION OF THE ATTRACTIVENESS OF DIFFERENT BAITS TO Rhynchophorus palmarum (COLEOPTERA: CURCULIONIDAE) AT PEACH PALM CULTIVATION (Bactris gasipaes) SUMMARY:The peach palm (Bactris gasipaes) has gained increasing economic importance to the region of Vale do Ribeira, SP. Few studies are conducted with this culture, but it is known that one of the limiting factors to its cultivation is associated with the occurrence of insect pests, such as palm weevil Rhynchophorus palmarum. Its larvae boring plant's stem may cause losses due to reduced tillering and opening holes that can serve as a gateway to pathogens. For management and monitoring of R palmarum it can be used bucket traps containing different attractive foods and synthetic pheromone RMD1. This study aimed to evaluate different baits on the attractiveness of R. palmarum. Five treatments were studied: pheromone; pheromone and sugar cane stalks; sugar cane stalks; pheromone and peach palm residue and only peach palm residue. The traps were rotated at five points of the arena set up in the field. Weekly evaluations indicated that treatment that contained pheromone and peach palm residue was more attractive to the weevil, being greater than other treatments. Otherwise, traps containing only sugar cane stalks as baits were not attractive for this weevil.
