Bees Like Big Hemp And They Cannot Lie, Study Shows

Some pollinators tend to flock to hemp, but according to a recent study, the taller the trees, the more plentiful the bees. Researchers at Cornell University collected bees at 11 hemp farms in the Finger Lakes region of central New York in the summer of 2018 to identify which ones are attracted to hemp and “to analyze the effects of landscape composition” when they visit the crop. In the study, published in the journal Environmental Entomology last week, the team found that plant height is “strongly correlated” with bee abundance and that hemp plants at least two meters tall attract “nearly 17 times the number of [bee] visits compared to short plants.” Both the sheer number and species of bees found visiting hemp “increased with plant height.” Additionally, they found that the cash crop can support 16 different bee varieties in the northeastern United States. Of the 355 individual bees captured by “repeated sweep net collections,” 60 percent were Apis mellifera, or western honey bees, while 30 percent were Bombus impatiens, the most commonly encountered bumblebee in eastern North America, which “is intensively relied upon” for pollination, the authors note. “As cultivation of hemp increases, growers, land managers, and policy makers should…
