Fig 3. Increased sensitivity of honey bees to the neonicotinoid insecticide acetamiprid.

Mean mortality (±SE) of honey bees fed 0.1 μg/μl acetamiprid with 1 mM solutions of inhibitors in sucrose syrup. All inhibitor-acetamiprid combinations had significantly greater 24 h mortality than the acetamiprid-only control (P < 0.0002).
