Abstract

The European corn borer (ECB) is the second most significant insect pest of field corn. Though its impact is variable each year, it can cause from $ 100 to $250 million in crop losses annually in Iowa alone. Presently, growers use chemical insecticides to suppress populations of this insect. But sometimes this approach does not provide adequate protection from this pest, in part because the ECB's tunneling damage within the corn stalk is usually recognized too late (see Figs. 1 and 2). Moreover, because chemical insecticides are not only expensive but potentially threatening to groundwater quality, corn growers need an environmentally compatible management alternative.
