WebAug 5, 2003 · 1 . Specialised nectar-feeding birds tend to prefer sucrose over glucose-fructose mixtures or to be indifferent when tested at concentrations close to 584 mmol L −1 sucrose equivalents. The role of the potential interaction between sugar composition and concentration on the sugar preferences of these birds, however, has not been explored. WebNov 12, 2024 · The western honey bee, Apis mellifera L. (Hymenoptera), is arguably the most important pollinator worldwide. While feeding, A. mellifera uses a rapid back-and-forth motion with its brush-like mouthparts to probe pools and films of nectar. Because of the physical forces experienced by the mouthparts during the feeding process, we …
WebAs sucrose concentration increased, the volume of solution ingested per meal first increased and then decreased gradually, while sucrose intake was highest at concentrations ≧40%. Females fed more than males at all concentrations >10% while temperature had no significant effect on meal size. WebAug 12, 2024 · We found that the optimal concentration of suction mode in honeybees coincided with the one calculated for other typical suction feeders. Moreover, we found …
