Western bean cutworm (WBC) infestations can cause significant yield losses and may facilitate subsequent colonization by pathogens, furthering damage and impacts. This pest has become an economic issue for many growers ranging from the Midwest through the Northeast US and Southern Ontario and Quebec. Losses from this insect can be as high as 8-10% in dry beans and 40% or more in field corn grain yields. WBC was first found in New York in 2009. This pest has expanded and has steadily increased across the state since first discovered. A trapping network was established in 2010 to monitor WBC populations as they invade NYS. There were not a lot of reports of economic damage by WBC this year. We also established a migratory insect pest-monitoring network for black cutworm (BCW) and true armyworm (TAW) with 25 locations in 2021. This was useful for knowing when BCW and TAW arrived in New York, and could potentially be used to. We could calculate degree-day models from the biofix dates.en-USAttribution-NonCommercial-NoDerivatives 4.0 InternationalAgricultural IPMField CropsField CornWestern Bean CutwormBlack CutwormTrue Armywormreport
