Brazil is the largest producer of passionfruit (Passiflora edulis) in the world, but holds low fruit productivity due to the lack of natural pollinators such as carpenter bees (Xylocopa spp.) in cultivated areas. The present work investigated the use in passionfruit plantations of a model of rational nesting box for carpenter bees suggested by FREITAS & OLIVEIRA FILHO (2001). Results showed that the introduction of inhabited nesting boxes in the studied area raised in 505% the frequency of carpenter bees to passionfruit flowers and in 92.3% initial fruit setting. Therefore, it is concluded that the use of this model of rational nesting boxes is efficient to increase carpenter bee population in an agricultural area and can contribute to increase levels of pollination and productivity in passionfruit plantations.
