Secrets of resistant varroa revealed

New research by Rothamsted has revealed the different gene mutations that have enabled varroa mites to become resistant to acaricides, including pyrethroids (such as the active ingredients of Apistan and Bayvarol). The findings have also helped explain Vita’s earlier observations about differing patterns of resistance across the world.

Tau-fluvalinate is a pyrethroid that can kill vulnerable mites by overstimulating their nervous systems. It interferes with sodium channel proteins that are involved in generating electrical signals in nerve cells.

Earlier research showed that resistance to tau-fluvalinate in central and southern England evolved through a mutation of a single base in the varroa’s DNA. This latest research has shown that a different mutation evolved in resistant varroa mites in the USA.

Dr Max Watkins, Technical Director of Vita (Europe) Ltd, explained: “In our ongoing studies of resistance to pyrethroids, we noticed that the pattern of resistance in the USA was different to that of the UK which was different again to that of continental Europe. We have long suspected that different mutations are responsible for these variations.

Swarming Infographic

SIGVita has produced a fun seasonal infographic about swarms. It’s free and downloadable from the Vita Gallery.

Go to the Vita Gallery to download the Swarm Infographic

Sebastian Owen of Vita (Europe) Ltd said: “We thought it would be a good idea to link Vita’s own research on swarms with some well-known, little-known and fun facts and folklore about swarms. We encourage anyone to download it, print it out and use it wherever they like. As beekeepers know well, healthy swarms are for sharing.”

Vita is also running a competition on its Facebook, Twitter and Google+ pages for anyone to win a free A3 poster version of the infographic.
