The yellow passion Passiflora edulis f. flavicarpa Deg. is allogamous, self incompatible, and it depends of insects pollinators to disseminate the pollen grains. The field work was conducted at Campos dos Goytacazes, Rio de Janeiro, Brazil, from October 17 to November 9 and December 12 to 21, 1995. It was analyzed 1565 flower buds, from which 423 showed well developed ovaries, five days after opening, this represents 27% of fruit set by natural pollination. It was observed 76,86 % of completely curved flowers, 21,22 % of partially curved flowers, and 1,92 % flowers without curvature. Five species of bees where observed on the flowers, from which two were the effective pollinator of yellow passion flower: Xylocopa (Megaxylocopa) frontalis (Olivier, 1789) and X.
