Mr Bush has been successful in keeping bees without treatment for years for this I applaud him. So has cao which I also applaud while recognizing many more have not realized this success and the reasons are wide, long, and also debatable... I really hope this topic
"Varroa detected in Australia" does not turn into a treatment vs non treatment debate. There are good points made for both sides of the equation; While recognizing good wholesome discussion is a win for all... I am posting a link from Beemaster, started by
"Salvo" just this past June, where we had such; a respectful 4 page discussion of Varroa packed with information, facts as well as theories concerning varroa in treating, non-treating, heavy hitters in beekeeping, different approaches and strategies concerning Varroa Destructor, links to top researchers for dealing with varroa by treatment, links concerning varroa by the quest and ongoing search for a 'truly varroa resistant bee' as well, and more... It is my hope that the information posted in
"Beemaster Forums" in the following link 'one of many' will be of aid to our friends in Australia...
