Honeybee floral constancy and pollination efficiency in sunflower (Helianthus annuus) crops for hybrid seed production

Honeybee Apis mellifera are considered essential pollinators in sunflower (Helianthus annuus) crops for hybrid seed production where they have to transfer pollen from male fertile (MF) to male sterile (MS) cultivars. Despite their biased preference for specific resources defined as floral constancy,...
