Although it is likely that a combination of different factors is contributing to the global bee die-offs, increasing attention is now devoted to the toxic effects of a group of pesticides called neonicotinoids, or neonics for short. They are systemic pesticides—their solubility in water allows them to reach leaves, flowers, roots and stems, even pollen and nectar. One could therefore infer that these pesticides will likely kill not only the insects that farmers want to eliminate, but also pollinators. Continue reading
