Abstract

In alfalfa the clonal preferences of Golden Italian, Apis Mellifera liguslica Spinola, and Carniolan, Apis mellitera carnica Pollmann, honey bees (chosen because of similarity in behavior and difference in color) were similar when they foraged alone in a cage during June and August 1965 at Manhattan, Kansas. Similarly, the parallelism of the clonal preferences of the 2 bee races, when foraging together in the cage, were striking. Equality of clonal attractiveness in field and cage was demonstrated for the 25 clones used. Preferences of neither honey bee race were appreciably altered by equalizing racemes per plant. The bee races appeared to compete for clones in foraging, but the effect on individuals of each race was about equal. Carniolans caged alone appeared to be more efficient pollinators of alfalfa than Golden Italians.
