Western Bean Cutworm
Western bean cutworm moths continue to emerge in the usual “hot spots” for this particular insect, especially across the central Plains and in the Great Lakes region. Egg laying/hatching is also occurring, and with a higher percentage of the corn crop nearing or in pollination/silking growth phases, Moderate risks continue across far northern Kansas, northeast Colorado, and into Nebraska. Additional Moderate risks are now in the forecast across central and northern Indiana, northwest Ohio, and into southern lower Michigan, as well, as crops in this area are beginning to reach or are in susceptible stages to damage. Low risks surround the Moderate risk areas where more isolated problems are expected, including far southern South Dakota, far western Iowa, extreme northwest Missouri, Wisconsin, and into central lower Michigan and southern Ontario, Canada. Growers are advised to not only regularly check traps but more importantly scout fields and look for egg masses and even potential larvae if the crop is at that point and where ears may be affected. Any treatments needed are very time sensitive as to their effectiveness so regular scouting is strongly encouraged.
