General linear model analysis considering the influence of the number of mites (covariate) on treatment efficiency via the ANCOVA (homogeneous slope) design revealed that the efficiency of anti-Varroa LiCl treatments did not vary with the sugar concentration of the trickling solution, whereas it differed between single and repeated treatments. Results of Tukey HSD post hoc tests are shown in Figure 2.
