Low corn earworm migration risks are in the forecast tonight into tomorrow morning especially across far eastern Illinois, Indiana, Ohio, and southern lower Michigan as well as into far southern Ontario, Canada as a rather deep area of low pressure drifts slowly east from Missouri/Iowa into central Illinois by tonight. While rainfall will certainly hamper migration possibilities further west, a combination of south to southwest winds along with more scattered precipitation may lead to isolated moth flights especially into the eastern corn-growing and southern Great Lakes regions overnight. No additional migration risks are predicted until late week into next weekend as southerly flow remains at bay until then. By late week into next weekend, fields from eastern South Dakota into the Great Lakes region will be at risk of some additional isolated moth flights as southerly winds return along with potential precipitation chances leading to isolated drop zone regions. Many area of the northern corn-growing region have seen corn earworm moth flights in the past few weeks with pressure remaining especially from Minnesota into Michigan, so growers should continue to monitor traps and scout fields especially where crop stage is susceptible to damage.
