A new way to assess the danger that pesticides can pose to bees

(The Bee Report) Discussing the hazards that different pesticides might potentially pose to bees can be a frustrating and tricky thing. The problem is that risk assessments are done with honey bees. And the honey bee is by no means representative of the roughly 3,999 other bee species in North America. Sure, a certain dose of a certain chemical under certain conditions might not kill off a perennial honey bee colony with tens of thousands of individuals. But what would the effect be on a single bee who is alive for only six weeks, raising her brood of eight? Especially when the greatest exposure to pesticides can come from the soil.
