Bees nosemosis in Roumania – therapeutic efficacy of plant dietary supplement [PDF]

open access: yes, 2022
Honeybee nosemosis, produced by two microsporidii species, Nosema ceranae and Nosema apis, is a serious disease which develops diarrhea, reducing honey production, increased mortality in winter and underdeveloped colony passed through illness. For treatment were tested over 200 compounds but only fumagillin and several organic compounds of mercury gave

Effects of Synthetic Acaricides and Nosema ceranae (Microsporidia: Nosematidae) on Molecules Associated with Chemical Communication and Recognition in Honey Bees

open access: yesVeterinary Sciences, 2020
Acaricides and the gut parasite Nosema ceranae are commonly present in most productive hives. Those stressors could be affecting key semiochemicals, which act as homeostasis regulators in Apis mellifera colonies, such as cuticular hydrocarbons (CHC ...
