导致密歇根-印第安纳地区蓝莓产量下降的主要因素似乎是授粉媒介数量少以及授粉媒介对蓝莓品种的强烈歧视。蜜蜂（Apis mellifera L.）对“Rubel”品种表现出强烈的偏好，而不是主要商业品种“Jersey”。在实验条件下，用作传粉媒介的蜜蜂将产量提高了近 5 倍。浆果大小和成熟率也有所增加。在良好的天气条件下，每英亩蓝莓有两个强大的蜜蜂群似乎足以满足授粉目的。在这个浓度下，蜜蜂似乎没有表现出品种偏好。两年的观察表明，可能需要改变施肥建议，以允许大量蜜蜂种群带来的年产量。实验地块的果实种子计数表明，观察到的果实特征的变化是由于授粉增加造成的。
The major factors contributing to the decline of blueberry yields in the Michigan-Indiana region seem to be low pollinator populations and strong discrimination by pollinators among blubbery varieties. Honey bees,Apis mellifera L., showed a strong preference for the ‘Rubel’ variety over ‘Jersey,’ the major commercial variety. Under experimental conditions, honey bees used as pollinators increased production nearly 5-fold. Berry size and maturation rate were also increased. Two strong colonies of honey bees per acre of blueberries under good weather conditions appeared to be adequate for pollination purposes. At this concentration honey bees did not appear to exhibit varietals preferences. Two-year observations indicate that fertilization recommendations may need to be altered to permit the heavy yearly production made possible by high honey bee populations. Seed counts of fruit from the experimental plots indicate that the changes observed in fruit characteristics resulted from increased pollination.
