"In 2017 Wonderful needed about 76,000 honeybee colonies to pollinate its almonds (at two colonies per acre). But that number will diminish by 320 this spring because Wardell will put 128,000 female BOBs into the orchards—the largest deployment ever."

So 128000 BOBs equals the pollinating effectiveness of 320 honeybees? That's a 400:1 honeybee/BOB ratio. Or perhaps they're just using really high margins because it's so experimental.
