The Honeybees Are Just Fine
Is a relatively new class of insecticides, known as neonicotinoids or “neonics,” harming bees and other wildlife? That’s what the International Union for the Conservation of Nature claimed in a recent press release announcing the results of a meta-study the organization conducted earlier this year. One might have expected the press release to be accompanied by the underlying scientific studies. But that wasn’t the case.
The proper way to engage in scientific debate is to publish studies so peers can confirm or refute the findings. Frustratingly, IUCN has only released one of its seven studies, preferring to conduct science by press release. This lack of transparency—together with the well-known anti-pesticide position of many of the scientists involved—raises suspicions as environmental groups lobby regulators to ban neonics in Canada and the U.S. The pesticides are already banned for two years in the European Union, and IUCN is calling for even-tighter restrictions and a global phaseout.
IUCN’s claims rest on the idea that neonics can be harmful to bees, worms, and other fauna, and that long-term exposure can cause “impaired sense of smell or memory; reduced fecundity; altered feeding behaviour; and reduced food intake” in species that feed on plants.
First introduced in the 1990s as a replacement for older, more toxic organophosphates and pyrethroids, neonics are often used to coat seeds to obviate the need for widespread spraying, thus reducing exposure to farm workers. Although we can’t know exactly how IUCN arrived at its conclusions, we can examine the existing science and published data, particularly on bees. These data don’t support the anti-neonics case.
