Estimation of honey bee colony infection with Nosema ceranae and Varroa destructor using fluorescence spectroscopy in combination with differential scanning calorimetry of honey samples
(Taylor and Francis, 2021)
In this preliminary study, we applied the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) method to analyze the excitation-emission matrices of multifloral honey samples, combined with differential ...
Honey bee colony loss rates in 37 countries using the COLOSS survey for winter 2019–2020: the combined effects of operation size, migration and queen replacement
(Journal of Apicultural Research, 2023)
This article presents managed honey bee colony loss rates over winter 2019/20 resulting from using the standardised COLOSS questionnaire in 37 countries. Six countries were from outside Europe, including, for the first ...
Preliminary trials on effects of lithium salts on Varroa destructor, honey and wax matrices
(International Bee Research AssociationTaylor and Francis, 2022)
In a cage experiment, lithium chloride (LiCl) and lithium citrate hydrate (Li-cit) were tested for varroacidal efficacy and impact on bees. Treatment with Li-cit (4, 7.5, 10, and 25 mM) resulted in 100% varroacidal efficacy ...
