Median lethal dose (LD₅₀) of acaricides to honey bees in 2009 following sublethal treatment with acaricides, fungicides, or detoxicative enzyme inhibitors.

<p>Confidence intervals (95%) are indicated below the LD₅₀ values. Significant differences compared to the control treatment are indicated with a superscript letter: a = significant pre-treatment effect, b = significant pre-treatment*acaricide dose effect (<a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054092#pone.0054092.s001" target="_blank">Table S1</a>). LD₅₀ values taken from previous work: † = <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054092#pone.0054092-Johnson3" target="_blank">[35]</a>, ‡ = <a href="http://www.plosone.org/article/info:doi/10.1371/journal.pone.0054092#pone.0054092-Johnson1" target="_blank">[22]</a>. Names for classical enzyme inhibitors are abbreviated as follows DEM = diethyl maleate, DEF = S,S,S-tributylphosphorotrithioate, PBO = piperonyl butoxide. A dash “−” indicates an LD₅₀ that could not be calculated because of insufficient data.
