The scientists exposed some of the studied bees to low doses of imidacloprid and tracked their movement with the help of electronic tags. Unexposed bees were also tracked, and each insect flying out and returning to a hive was weighed to find out the amount of pollen it gathered. It turned out that bees exposed to the neonicotinoid brought back pollen from only 40 percent of their trips asopposed to 63 percent of useful trips which their “healthy” counterparts undertook. Intoxicated bees cut the amount of pollen gathered by nearly a third – overall, the comparative study showed that the hives exposed to the pesticide received 57 percent less pollen. “Even near-infinitesimal doses of these neurotoxins seem to be enough to mess up the ability of bees to gather food. Given the vital importance of bumblebees as pollinators, this is surely a cause for concern,” Hannah Feltham of the University of Stirling, another member of the research team, stated.

Well along those lines HL I also feel that it will eventually effect humans also if it hasn't already. We like to think of ourselves as being so superior but we are still a carbon based life form as are the insects. So if it kills them it will kill us. Rachael Carson, Silent Spring. You are right it does not take a chemist to figure this out.
Not very well ;( Hiya suzie!
