Most biodiesel (I own a vw diesel) comes from vegetable oils with soybean the greatest contributor. I do not know how much commercial pollinators are involved with soybean pollination, so that would be the the link of bees, pollination and education. Corn, obviously is not. Other players are canola, which is commercially pollinated as well as sunflowers, which have a major increase in seed production from honeybees. So the key is soybeans, and what I have seen is that there is an increase (small to .95x depending on variety) in production by bees, but not the many-fold increase as with other crops like sunflowers (3x or more).
