Domesticated honeybees get all the buzz, but wild bumblebees are in decline too, both globally and here in the United States. What gives? It’s an important question, because while managed honeybees provide half the pollination required by US crops, bumble and other wild bees deliver the other half.
Insecticides used in agriculture are one possible trigger—they exist to kill insects, after all, and bumblebees are insects. But a different kind of farm chemical, one designed to kill fungi that harm crops, has emerged as a possible culprit. A new study by a team of researchers led by Cornell University entomologist Scott McArt adds to the growing dossier of studies pinpointing fungicide as a potential bee killer (see here, here, and here).
