DEAD COLONY FORENSICS

摘要

Bees die overwinter for a number of reasons. Of course, seasonal losses occur as well, and they too might have a number of root causes. By performing a dead colony necropsy we might be able to determine the likely reason for non-survivorship. Althoughdead colony examinationsare often not clear cut, understanding the why might help us avoid a repeat the next timeThis Spring I joined about a dozen brave individuals gathered in a Portland, OR club apiary mid-April, during a steady Oregon "liquid sunshine" rain event, to do a deadcolony examination workshop. Temperature was low 50s, with only a couple foraging bees venturing forth from four of eight colonies. We did necropsy on two deadouts.
