A new study provides valuable insights into pollen abundance and diversity available to honeybee colonies employed in five major pollinator-dependent crops in Oregon and California, including California’s massive almond industry.
The study, a collaboration between OSU and Texas A&M University, found that almond, cherry and meadowfoam provide ample pollen to honeybees, but highbush blueberry and hybrid carrot seed crops may not. In addition, California almonds don’t provide as much pollen diversity as other crops, according to the findings, published in the Journal of Economic Entomology.
The western honeybee is the major pollinator of fruit, nut, vegetable and seed crops that depend on bee pollination for high quality and yield. The findings are important because both pollen abundance and diversity are critical for colony growth and survival of the western honeybee, said study corresponding author Ramesh Sagili, associate professor of apiculture and honeybee Extension specialist in OSU’s College of Agricultural Sciences.
“Pollen diversity is important for the growth and development of bees, and low amounts of pollen availability to honeybee colonies can dramatically affect brood rearing,” Sagili said. “Beekeepers that employ their colonies for pollination of crops like hybrid carrot seed and highbush blueberry should frequently assess the amount of pollen stores in their colonies and provide protein supplements if pollen stores are low.”
