| description | <i>Varroa destructor</i> is a parasitic mite, which is considered a severe pest for honey bees causing serious losses to beekeeping. Residual hydrolats from steam extraction of hop essential oils, generally considered as a waste product, were tested for their potential use as acaricides on <i>V. destructor</i>. Four hop varieties, namely Cascade, Spalt, Victoria, and Mapuche, showed an interesting performance as feasible products to be used in the beekeeping industry. Some volatile oxidized terpenoids were found in the hydrolats, mainly β-caryophyllene oxide, β-linalool, and isogeraniol. These compounds, together with the presence of polyphenols, flavonoids, and saponins, were probably responsible for the promissory LC<sub>50</sub> values obtained for mites after hydrolat exposition. Victoria hydrolat was the most toxic for mites (LC<sub>50</sub>: 16.1 µL/mL), followed by Mapuche (LC<sub>50</sub> value equal to 30.1 µL/mL), Spalt (LC<sub>50</sub> value equal to 114.3 µL/mL), and finally Cascade (LC<sub>50</sub>: 117.9 µL/mL). Likewise, Spalt had the highest larval survival, followed by Victoria and Mapuche. Cascade was the variety with the highest larval mortality. In addition, none of the extracts showed mortality higher than 20% in adult bees. The Victoria hydrolat presented the best results, which makes it a good compound with the prospect of an acaricide treatment against <i>V. destructor.</i> |
