- Low mite-infested colonies were defined as < 3 mites/100 bees and high mite-infested colonies were defined as > 8 mites/100 bees. The uppercase letters represent statistical significance within the row (low vs. high mite) and lowercase letters represent statistical significance within the column (paraquat concentrations). Rows or columns not labeled by the same letter represents statistical significance at P < 0.05 as determined by a one-way analysis of variance (ANOVA) followed by Tukey’s post-test
