Add to ORKGIncreased activity of bean leaf beetles and soybean aphids in Iowa soybean fields has challenged many of us over the last five years. Not just because of the sap feeding and leaf defoliation that can cause significant yield loss but also because we are dealing with another yield robber that we often can\u27t see. Iowa soybean fields can be infected with bean pod mottle and soybean {m}osaic viruses that are transmitted by bean leaf beetles and soybean aphids, respectively. The challenge that we are dealing with is, first of all, we can\u27t always see that we have a virus in soybean, and yield loss caused by viruses can occur even when symptoms are not apparent
