Acute toxicity of Advise (imidacloprid) and seven binary pesticide mixtures to honey bees.

All concentrations used are listed in Table 1 as LC₂₀ determined in a previous study [30]. Advi, Brac, Kara, Vyda, Doma, Roun, Tran, and Bela were used as abbreviations for the same order of eight pesticides listed in Table 1. Same letters above the error bars indicate no significant difference: lower case letters are for within-group comparisons; capital letters refer to comparisons among all treatments. The corrected mortality from Advise only was reused in each group for within-group comparison and statistics.
