A research group from the University of Guelph (Ontario, Canada) has now taken a closer look at varroa mite sensitivity towards different miticides in the province (amitraz, flumethrin, tau-fluvalinate).
The damaging effects of high varroa mite infestation and high prevalence of DWV (Deformed Wing Virus) on honey bee colony health are well known and continue to be a widely investigated subject.
As the days are getting longer, and we are all looking forward to those extra rays of sunshine, you are not alone in the desire to stretch your legs and get fit for the warm season. Your bees are “stretching their antennae” too – so to speak – to prepare for a new colony buildup.
Effects of rising temperatures due to global climate change on honey bee colony development and health have been suggested in the past and are increasingly being investigated.
