A. Percent colony losses (mean ± SEM) in 2006–2007 and the three years prior. The bars with different letters indicate significantly different percent colony losses at P < 0.05. B. Beekeepers reporting CCD-like symptoms in 2007 reported higher colony losses even in years where general losses were typical. * indicates a significant (P < 0.05) difference across colony mortality of beekeepers with (black bars) and without (white bars) CCD symptoms.
