Approximately 70% of 1330 tropical crop types benefit from animal pollination (Roubik and (Ed.) 1995). Likewise, it is of great importance in the maintenance of genetic diversity of wild plant communities in natural ecosystems and in agricultural production (Potts et al. Pollination represents a critical ecosystem function in life support that is crucial for planetary ecological stability and the provision of services and resources for food production (Crenna et al. Our results suggest that large body sizes in bees are the most important traits in granadilla pollen transport, regardless of other changes in composition and structure of pollinating insect assemblages in the crop. None of the functional traits evaluated was influenced by taxonomy at species-level. Body size was the most important trait determining the transport of sweet granadilla pollen, while the traits related to body hairs were not significant for the body’s pollen load. Bombus hortulanus (Smith) was one of the large-bodied native bees that carried more sweet granadilla pollen, despite not being an abundant species in the community. Within these, the most abundant species was the exotic common honeybee ( Apis mellifera (Linnaeus)) making up almost half of the specimens collected however, this bee carried less pollen grains than other native bees. Bees (Apidae) were not only the most abundant insects but also the ones that loaded the highest amounts of pollen. We sampled flower-visiting insects of this crop and recorded 10 functional traits (five by direct measurements and five from the literature) that were related to the amount of pollen carried by each insect. We explore the relationship between pollinator insect functional traits and the transport of pollen of sweet granadilla ( Passiflora ligularis Juss) in eight crops. However, the contribution of different functional traits of insects for pollen transport of plants is still poorly known. Pollination is a vitally important function in nature and becomes an ecosystem service because it influences the food and nutritional security for people.
