Sustainable tree for fruit pollination; Assuring pollination of fruits in the Mid-Atlantic Region
A possible link between neonicotinoids and honey bee die-offs has led to controversy across the United States and Europe. Beekeepers and environmentalists have expressed growing concern about the impact of neonicotinoids, concern based on the fact that neonicotinoids are absorbed into plant tissue and can be present in pollen and nectar, making them toxic to pollinators.
This video highlights the behavioral differences of two common orchard pollinators in Pennsylvania. On the left is a Blue Orchard Bee (Osmia lignaria), and on the right a Japanese Orchard Bee (Osmia cornifrons). This was recorded during a feeding assay, in which both bees were fed a sucrose solution. As you can see the O. cornifrons is much more active and agitated. It's possible that this has implications on their pollination behaviors and success.
