Depending on when the moths arrive in Minnesota and temperatures, black cutworms will go through one or more generations until late-summer conditions trigger a southward migration. The black cutworm goes through a complete metamorphosis with egg, larval, pupal and adult stages. In addition to corn, the larvae feed on a wide range of broadleaf and grass crops, weeds and other plants. Black cutworm adults feed on plant nectar. The larva -caterpillar - is the life stage that damages crops.

In these areas, annual infestations are produced by moths migrating from southern overwintering areas each spring. Although a native of North America, it can’t survive winters in Minnesota or other latitudes with freezing winter temperatures. The black cutworm – Agrostis ipsilon Hüfnagel (Lepidoptera: Noctuidae) – is widely distributed in the temperate regions of the world. economic thresholds, chemical control, transgenic control, and biological control andīy the end of this presentation, the practitioner should know more about the ecology and management of western bean cutworm and how to implement integrated pest management and resistance management techniques for this damaging pest.Find information about black cutworm in Minnesota corn, including their characteristics, habitat, at-risk fields, signs of damage and strategies for managing infestations.integrated pest management options, such as population monitoring, field scouting,.range expansion and current pest status.Specifically in this presentation, practitioners will learn the following about western bean cutworm: This presentation will help consultants, growers, and other practitioners, particularly in the western Great Plains, to understand Integrated Pest Management options for controlling western bean cutworm. Infestations in field corn are capable of inflicting up to 40% yield loss and can also lead to secondary fungal infections, decreasing grain quality. While the western bean cutworm has long been a pest of corn and dry beans in the western Great Plains region, its significant range expansion eastward in the past 16 years has greatly increased the potential damage that this pest can do.
