In my experience most commercial beekeepers use cyanide gas to kill their bees after harvesting the honey; they start fresh with new queens in spring. The rare few who overwinter their bees use sugar syrup and store the bees in a cool warehouse designed to keep them dormant during winter.

From a commercial beekeeping perspective "colony collapse disorder" is nothing but a recent news fad. There are cycles of different problems for decades, but I doubt there is something extraordinary about the current state of beekeeping.

Killing the makers of your livelihood and dealing with catastrophic problems is usually known as "farming".
