The objective of this field trial was to evaluate the efficacy of a single application of foliar
insecticides at preventing feeding damage by the western bean cutworm (WBC), an
important pest of corn and dry beans. Direct feeding by WBC larvae on developing kernels
in the ear can result in yield loss, whereas WBC infestation can also lead to secondary
fungal infections. WBC has undergone a rapid range expansion into the eastern Corn Belt
within the last 16 yr. This study was conducted within the historic range of WBC, at the …

The western bean cutworm (WBC) is an important pest of corn and dry beans. In addition to
yield loss due to direct feeding on developing kernels in the ear, WBC infestation can also
lead to secondary fungal infections. This study was conducted within the historic range of
WBC in western Nebraska; however, it has undergone a rapid range expansion into the
eastern Corn Belt within the last 16 years. This field trial was established to evaluate the
efficacy of a single application of foliar insecticides against this pest to prevent feeding …
