Solutions of 1.0 and 1.5% OA gave similar mite control (98,39 ± 0,01% and98,28 ± 0,01%); the 0.5% aqueous solution gave a weaker, but significant effect (94,92± 0,00%) (ANOVA, LSD test, F3;8 = 4466.64, p = 0.00) (Fig. 1). However, the 1.0 and1.5% concentrations were highly toxic to bees: about twice the number of bees in thecolony died according as estimated in the Liebefeld method (Gerig; 1983, Imdorf et al.,1987) before and after the spraying experiments (t-test, p < 0.05). The 1.0 and 1.5%concentrations weakened the colonies considerably, whereas the 0.5% solution had nonoticeable toxic effect
