Organic farming has increased to an $8 billion industry in the United States and continues to expand approximately 20 percent annually. The current 20-400 percent market premium for certified organic products has served as a powerful incentive for producers. Bean leaf beetles are one of the few insect pests lacking any natural enemies (parasites, predators, or pathogens) on organic farms in the Midwest. Because the bean leaf beetle is associated with bean pod mottle virus and fungi that stain the soybean seed coat, many soybean seeds have been rejected from the premium tofu/soymilk market since 1997.
