Pan traps of various heights and colors were tested to determine the optimal combination for monitoring pollinators in highbush blueberry. Captures of bees were compared from 12 oz yellow bowls placed at 0, 2, 4, and 6 ft above the ground between blueberry plants and deployed for 9 h. Yellow, blue and white bowls of the same size were compared at 4 ft height. Captured bees were identified to genus for members of family Apidae and to family for all others. Significantly more solitary bees were captured in pan traps positioned at 2 ft compared to the other heights. Trap color did not significantly affect the total number of bees trapped. White and yellow traps at the optimal height were used to monitor bees at eighteen commercial Michigan blueberry fields to examine how surrounding landscapes influence abundance and diversity of non-managed bees. Results from the first year of this research will be discussed.
