Animals assess the quality and quantity of food and choose among different foods based on these assessments. We explored whether there was genetic variation for assessment of pollen quality by foraging honey bees,Apis mellifera. Honey bees derived from two genotypic strains foraged for pollen of varying quality from a petri dish placed inside an outdoor flight cage. The strains were the result of...
The amount of pollen stored in honey bee, Apis mellifera, colonies is a selectable trait. Five generations of two-way selection resulted in high and low strains that differed more than six-fold in quantities of stored pollen. Comparisons with hybrid crosses suggested that colony-level, high pollen-hoarding behaviour is inherited as a recessive trait. Colony levels of stored honey, however, showed...
