An increase in bean leaf beetles has caused an increase in bean pod mottle virus - a yield robbing plant pathogen in Iowa soybeans. The incidence of bean pod mottle virus is often positively correlated with bean leaf beetle populations. For example, the greatest increase in bean pod mottle virus infection occurs after the first generation of bean leaf beetles reaches peak population density (late July). However, soybeans are most affected when soybeans are infected as seedlings.
