Africanized honey bees (Hymenoptera : Apidae) have a greater fidelity to sunflowers than European bees

A study of sunflower, Helianthus annuus L., pollen collection by Africanize d and European honey bees, Apis mellifera L, was conducted in a hybrid seed production field in Argentina. Africanized honey bees collected significan tly larger proportions of sunflower pollen than did European honey bees. Th e result suggests that Africanized bees would be more efficient for commerc ial sunflower seed production.
