The pollination of California's almonds is the largest annual managed pollination event in the world, with close to one million hives (nearly half of all beehives in the USA) being trucked in February to the almond groves. Much of the pollination is managed by pollination brokers, who contract with migratory beekeepers from at least 49 states for the event. This business has been heavily affected by colony collapse disorder, causing nationwide shortages of honey bees and increasing the price of insect pollination...
Does anyone feel that transporting livestock from this many places to a single place where they can all commingle is a needlessly risky strategy? Assuming that CCD is caused by pesticides, this seems to guarantee exposure to a large number of bees that might otherwise live in pesticide-free areas. Additionally, if CCD has a fungal/parasitic component, then this would be an ideal way to infect as many hives as possible, in as short a time as possible.
