Effect of the porphyrinoid PP(Asp)2 on the mortality of the uninfected honeybees (A) and honeybees infected with microsporidia (B) in the cages over 12 days of the experiment. Lowercase letters (a, b) indicate significant differences between the control (bees fed pure sucrose syrup), PP(Asp)2 −10 µM and PP(Asp)2 −100 µM (bees fed with sucrose syrup supplemented with the porphyrin at concentrations of 10 and 100 µM, respectively) experimental groups (p ≤ 0.05) (ANOVA, Tukey test).
