Abstract

Each spring, black cutworm moths migrate into Iowa from southern states, and they lay eggs in soybean stubble (a preferred site) and corn stubble. Also, at the same time, we invariably experience some early spring cold temperatures that drop below freezing. When these two events occur simultaneously, it doesn't take long before people begin asking what the freezing temperatures did to the black cutworms.
