  • In experiments, researchers showed that bees initially put off by sugar water containing neonicotinoids — the most widely-used class of insecticides worldwide — soon started seeking them out to the exclusion of untainted food.
  • Neonicotinoids, earlier research has shown, disrupt the ability of bees to reproduce and lower their resistance to disease.
  • Even when the position of their feeders was switched, the pollinators made a beeline for the one laced with insecticide.
  • Neonicotinoids target nerve receptors in insects.
  • The United Nations warned last year that 40% of invertebrate pollinators risk global extinction.
