Tsvetan Tsvetanov

Abstract: The infestation of bee families bred in the experimental apiary of IAS-Kostinbrod was studied. Queen bees are sisters of the breed Apis mellifera macedonica. The survey was conducted in two consecutive economic seasons 2018-2019. Prior to initiation of the study, initial and final infections were determined. The experiment was carried out in August in Kostinbrod at an altitude of 530 m. For families in the experimental groups, mites were recorded on the first and fifth days of administration of the drug. Oxalic acid was administered to all families as a control treatment. The effect of the drugs on the amount of mites dropped by the bee families during the two business seasons 2018-2019 was assessed by one-way ANOVA, and the differences between the two treatments with the drugs were established by t-test. Pre-treatment and post-treatment differences in pre-treatment and posttreatment levels are highly reliable (p < 0.001).) When using the Bipin-T. preparation p < 0.001). A highly significant effect was observed between the period of the first and the second treatment with the medicines and the amount of mites dropped during the studied business seasons 2018-2019 (p < 0.001).
