Mean (±SE) cumulative bee mortality (%) in treatments when worker bees were exposed to different doses of amitraz (3.91 mg, 0.391 mg or 0.0319 mg), solvent (acetone) or left untreated (control) in a 800 mL Apiarium or in a 60 mL Mason jar through 4 h and 24 h assessments. Each value represents an average of replicates for jars (n = 5) or Apiariums (n = 3). Means within each row followed by the same letter among treatments are not significantly different (p> 0.05).
