Scientists then measured the levels of these markers in a collection of queens in B.C. that had failed in the field, and found that they had higher levels of heat-shock and pesticide protein markers compared to healthy queens. The results pave the way for a future diagnostic test to help beekeepers understand, and prevent, queen bee failure in the future.
