Honeybees prefer warmer nectar and less viscous nectar, regardless of sugar concentration.
The internal temperature of flowers may be higher than air temperature, and warmer nectar could offer energetic advantages for honeybee thermoregulation, as well as being easier to drink owing to its lower viscosity. We investigated the responses of Apis mellifera scutellata (10 colonies) to warmed 10% w/w sucrose solutions, maintained at 20-35°C, independent of low air temperatures, and to 20%...
متن کاملSugar Metabolism in Hummingbirds and Nectar Bats
Hummingbirds and nectar bats coevolved with the plants they visit to feed on floral nectars rich in sugars. The extremely high metabolic costs imposed by small size and hovering flight in combination with reliance upon sugars as their main source of dietary calories resulted in convergent evolution of a suite of structural and functional traits. These allow high rates of aerobic energy metaboli...
متن کاملNectar Availability and Parasitoid Sugar Feeding
Habitat diversification can potentially benefit natural enemies by providing alternative prey, a suitable microclimate, or nectar and pollen (Landis et al., 2000). Laboratory and field cage studies demonstrate that parasitoids with access to sugar have greater longevity, fecundity, and more femalebiased sex ratios than starved parasitoids (Idris and Grafius, 1995; Dyer and Landis, 1996; Berndt ...
متن کاملEnergy saving strategies of honeybees in dipping nectar
The honeybee's drinking process has generally been simplified because of its high speed and small scale. In this study, we clearly observed the drinking cycle of the Italian honeybee using a specially designed high-speed camera system. We analysed the pattern of glossal hair erection and the movement kinematics of the protracting tongue (glossa). Results showed that the honeybee used two specia...
متن کاملModeling Function of Nectar Foraging of Honeybees using Operant Conditioning
Behaviors of the colonies of small unsophisticated agents have been analyzed in the literature with the purpose of developing efficient algorithms to solve complex, dynamic and burden problems in other societies. Among them, only a few research have been conducted in the area of swarm cognition which tries to understand the cognitive behaviors exhibited by human brain by using the cognitive beh...
