Varooacidna učinkovitost primjene dodatka hrani tijekom ljetnog tretmana zajednica medonosne pčele (Apis mellifera)
The aim of this field study was to evaluate the varroacidal efficacy of the product Hive Clean® during summer treatment of honeybee colonies (Apis mellifera). Treatment efficacy was assessed by counting the number of Varroa destructor mites killed after multiple applications of Hive Clean®, according to the instructions provided by the producer. Hive Clean® was applied consecutively, with two varroacides with different active ingredients as shock treatment. The treatment with Hive Clean® resulted in a median mite drop of 91.51% (89.25-93.26%). Total mite mortality was always significantly higher than the natural mite fall observed during the pre-treatment period. According to the results obtained, Hive Clean®, as a food additive with acaricidal effect, could be considered an appropriate alternative for varroosis control and also suitable for use in combination with authorized veterinary medicine products, in organic and conventional apiaries under mild climate conditions.Cilj ovog istraživanja bio je utvrditi učinkovitost Hive Clean® proizvoda tijekom ljetnog tretmana zajednica medonosne pčele (Apis mellifera) protiv varooze, u poljskim uvjetima. Učinkovitost tretmana je utvrđena brojenjem otpalih grinja Varroa destructor nakon višekatne uporabe Hive Clean® proizvoda prema uputama proizvođača, kao i nakon kombinirane uzastopne primjene dva varooacida s različitim aktivnim tvarima. Nakon provedenog tretmana s Hive Clean® proizvodom prosječna učinkovitost pada grinja iznosila je 91,51 % (89,25-93,26 %). Ukupan broj otpalih grinja je u svim tretiranim zajednicama medonosne pčele bio značajno veći u odnosu na prirodni pad grinja utvrđen tijekom razdoblja prije tretmana. Sukladno dobivenim rezultatima provedenog istraživanja učinkovitosti Hive Clean® proizvoda, kao dodatka hrani s akaricidnim učinkom, može ga se smatrati prikladnim za kontroliranje varooze. Također, prihvatljiv je za uporabu u kombinaciji s odobrenom veterinarsko medicinskim proizvodima za kontroliranje varooze, i to u pčelinjacima s ekološkim i konvencionalnim načinom pčelarenja
