Insecticides And Hive Death

New Evidence that Our Insecticides are Killing Off the Bees

Scientists call the mysterious wasting-away of the the world’s bee populations “colony collapse disorder.” Researchers have come up with numerous hypotheses to explain the collapse, including parasites, viruses, and — yes — insecticides, but quantifying the impact of these and other suspects has proven to be an onerous task.

Two studies, which are published in this week’s issue of Science, opted to take a closer look at a class of insecticides called neonicotinoids. Neonicotinoids have been linked to colony collapse in the past; the incredibly effective pesticide works by spreading throughout the seeds and stems of treated plants; making its way into nectar and pollen supplies, where it is picked up by pollinators like bees; and, finally, attacking the nervous system of the exposed insects.
