Optimal concentrations in nectar feeding

Webof nectar trapping, as opposed to capillarity, while feeding (cf. 2, 5). Hence, the outputs of their model and conclusions with regard to optimal concentrations in nectar feeding may be broadly unrealistic. Alejandro Rico-Guevara1 and Margaret A. Rubega Department of Ecology and Evolutionary Biology, University of Connecticut, Storrs, CT 06269 1. 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.
