Abstract

I fielded a dozen calls regarding whiteflies in Iowa soybeans during the week of July 30-August 3. This insect is probably the sweetpotato whitefly, Bemisia tabaci, but its identification has yet to be confirmed. The primary concern expressed by the callers seems to be whether this insect can cause yield loss in soybeans, either by themselves or in concert with soybean aphids. Almost nothing is known about them in Midwestern soybeans, but Mike Gray, University of Illinois, did report them from soybeans in 1999 in that state. I reported them from Iowa soybeans last year in this newsletter.
