Preliminary trials on effects of lithium salts on Varroa destructor, honey and wax matrices
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 and 100% bee survival. Due to better results in the cage experiment, Li-cit was further tested in field experiments on full-sized…
