Cerotoma trifurcata
Bean Leaf Beetle
Cerotoma trifurcata, commonly known as the bean leaf beetle, is a chrysomelid beetle native to North America and a significant agricultural pest of soybean and other leguminous crops. Adults overwinter in sheltered woodland edges and fence rows, migrating to soybean fields in spring to feed and reproduce. The species has been documented as a vector of Bean Pod Mottle Virus (Comoviridae), transmitting the pathogen between plants during feeding. Its life cycle includes soil-dwelling larval stages that feed on root nodules, potentially affecting nitrogen fixation in host plants.
