For honey bees, queen health is synonymous with colony health.  Failing queens are a common reason cited for colony losses. New research, funded in part by PAm, describes conditions when queens might be vulnerable to heat stress, which could damage fertility. 

​The first round of the North American Mite-A-Thon is right around the corner. From May 2nd through May 17th submit your mite counts to help keep track of varroa across the United States, Canada, and Mexico.
​
You can also participate in the second round of mite counting, August 15th through August 30th. 
 
Use a sugar shake, or an alcohol wash, to measure your varroa and submit your data here.  The Honey Bee Health Coalition has a video demonstrating both methods.
