"Efforts To Kill Invasive Plant Worry Beekeepers"

"An effort to fight an invasive plant with insects that eat it has drawn opposition from beekeepers who worry it will leave them without an adequate source of nectar and pollen for their honeybees.

Researchers in Michigan released bugs that feed on spotted knapweed earlier this year. Western states and big honey producers, such as Minnesota and Wisconsin, previously used so-called biological control to help restrain the flowering plant, which produces chemicals that deter the growth of other plants and crowds out native vegetation."
