Figure 3. Pollen recovered from honey bee colonies during and after exposure to canola grown from control or clothianidin-treated seed.

Mean amount of pollen recovered from pollen traps on honey bee colonies during and after placement in canola fields grown from seeds treated with or without (control) clothianidin (n = 5 fields per treatment). Colonies were in canola for 14 days and thereafter moved to an isolated apiary away from agricultural crops.
