Defensiveness of honeybee colonies of Apis cerana and Apis mellifera (actively balling the wasps but reduction of foraging) against predatory wasps, Vespa velutina, and false wasps was assessed. There were significantly more worker bees in balls of the former than latter. Core temperatures in a ball around a live wasp of A. cerana were significantly higher(More)
The ectoparasitic mites Varroa destructor and Tropilaelaps mercedesae share life history traits and both infect honeybee colonies, Apis mellifera. Since V. destructor is a biological vector of several honeybee viruses, we here test whether T. mercedesae can also be infected and enable virus replication. In Kunming (China), workers and T. mercedesae mites(More)
Diffuse Lewy body disease is characterised pathologically by the presence of rounded eosinophilic intraneuronal inclusion bodies (Lewy bodies) in brainstem nuclei (where the changes are indistinguishable from those of idiopathic Parkinson's disease) and throughout the cerebral cortex.' The disease has recently attracted attention as a potential pathological(More)
