Corn is one of the leading field crops in the Stavropol region. It is sown for grain annually on an area of about 120 thousand hectares. Many farms use it as a monoculture, sowing in one place for 3–4 years in a row. This makes it possible for the main pest of maize, the cotton bollworm, to stably maintain its population in field crop rotations for many years, not only in corn crops, but also to spread to other crops. The article provides information on the morphology, biological features of the cotton bollworms development in corn crops.
