Re: Neonic facts
Yes as a general rule, plants that are wind pollinated have a very low nutrient pollen that is not beneficial to bees, it has to be this way to make the pollen grains as light as possible. Bees can mostly detect this, although I have seen bees gathering pollen from wind pollinated pine trees, this at a time when there were few options.
To me, it is not impossible that bees could collect contaminated pollen from something that's been sprayed with a systemic insecticide, including neonics. There is scant evidence though, but it's something I feel we should be aware of it could be from beekeepers own observations that breakthroughs are made.
Jim, were that researchers hives in a situation where they suffered pollen shortage but still did not collect the corn pollen? If so, that would help eliminate corn pollen as a danger although of course it's just one experiment.
44 years, been commercial, outfits up to 4000 hives, now 120 hives and 200 nucs as a hobby, selling bees. T (mostly).
