Resumen:
Honeybees Apis mellifera are important pollen
vectors for many crop plants. In some crops, productivity is ensured only
through the pollination service of this insect species. Beekeepers use to condition honeybee
colonies by feeding them with syrups containing crushed flowers of the species
that pretend to be pollinated. Despite the use of this procedure little
is known about the process that guide bees to the flowers of crop plants or
about the dynamic and extent to which floral scent contributes to pollinator
attraction in agricultural settings. Recent studies show that insect
pollinators need only a few volatile compounds to recognize a specific floral
scent. Based on this idea, we developed synthetic mixes of volatile compounds
that bees confound with the natural floral fragrances of some specific crop
plants. Our hypothesis is that memories established by the offering of synthetic-mix
odor within the colonies (i) are used to orientate pioneer foraging bees while
search for food nearby the crop field; and (ii) facilitate the transference of
crop-related information through recruiting mechanisms such as dances. As an
example, we will show evidences at the levels of cognition, orientation and
navigation that suggest a prompt foraging task in sunflower crops, a fact that opens the possibility for an
improved efficiency in pollination and crop yield.
