There was an article in our Sunday paper regarding bee populations. Almond growers here are concerned about a lack of colonies for spring pollination.
The paper interviewed commercial beekeepers for the story and these beekeepers report losing anywhere from 30% to 50% of their hives due to mites. They expect to lose additional colonies over this stretch of the winter. They claim the mites are becoming resistent to the chemical treatments.
Is this true? Are the mites becoming resistent to Check Mite? Beekeepers in my area were noticing that Apistan was no longer effective in controlling mites and were starting to use Check Mite. I am curious as I am going to start some colonies again this spring.
