Objective:
Determine the expression rates in nectar and pollen of imidacloprid in three tree species and the potential impacts of pesticide residues on pollinators.

Approach:
APHIS is proposing to treat multiple species of hardwoods located in and around Worcester County, Massachusetts, with imidacloprid (IMI) to help eradicate the invasive Asian longhorned beetle (ALB). The treatment of these trees (by injection and soil application) should result in translocation of IMI throughout the tree and could result in the potential expression of IMI in nectar and pollen. USDA-ARS is proposing to monitor the movement of IMI to pollen and nectar and evaluate the potential effects on honeybees and other non-target species over a three year period.
