The overwintering bean leaf beetles are gone and we are looking forward to the appearance of the first-generation adults. The second generation, not the first, will have the greatest impact on yield by feeding on the soybean pods and beans. Monitoring the first generation, however, can aid in the management of the second generation. Larry Pedigo and his students at Iowa State University have developed research-based information to help make a management decision for second-generation bean leaf beetles based upon the population size of the first-generation bean leaf beetles. This article reviews this management concept, which was presented last year.
