Caged honey bees, Apis mellifera L., are often used to pollinate white clover, Trifolium repens L., particularly when a large number of controlled crosses are needed. A hive with openings on opposite sides was placed in one end of a screen cage so honey bees would be free to travel into or outside the cage. Clover clones with genetic leaf markings were used as indicator plants to determine if pollen was brought into the cage from outside sources. .chi.2 Analysis of the ratio of resulting progeny indicated that crosses were made only from pollen of the red leaf-marked clover.
