An effort to kill an invasive plant by releasing bugs that eat it has drawn the ire of some beekeepers in Michigan.
They say the plant provides an important source of nectar and pollen to keep honeybees productive and healthy.
Researchers released insects in Michigan this year to see if their feasting would help control spotted knapweed. The plant produces chemicals that deter the growth of other plants and crowds out native vegetation.
Western states and big Midwest honey producers like Minnesota and Wisconsin have previously used bugs to kill knapweed. It's unclear why the method is drawing such opposition in Michigan and not elsewhere.
Michigan officials say they're looking at ways to use native flowers as a replacement for knapweed.
Michigan is among the nation's top 10 honey producers.
