Preliminary evidence associating oxidative stress in honey bee drone brood with Varroa destructor
Zbigniew Lipinski and Krystyna Zóltowska
Significantly high activity of three antioxidant enzymes isolated from tissues of Varroa destructor-infested drone prepupae suggest that oxidative stress may be one of the pathogenic pathways of varroosis. The average activity of superoxide dismutase (SOD), glutathione peroxidase (GPX) and plasma protein ceruloplasmin (CP) in infested prepupae were approximately 2–4 times (i.e. significantly) higher than levels in mite-free prepupae. All prepupae were taken from a naturally-infested colony where 47% of prepupae were infested with from 1 to 3 mother varroa mites.
