Abstract. Pests damage maize throughout the growing season, causing enormous damage to the plants. Various methods and tools are used to suppress them. It is important to ensure that certain measures are carried out on time, taking into account biological and environmental characteristics of the pests’ morphosis. An important place in solving the problem of increasing food production is occupied by the production of food and feed maize grains. In this regard, it is important to develop effective ways and methods of creating hybrids with high productivity and resistance to various extreme environmental influences and harmful organisms.Asignificant place is given to the diagnosis of the damage caused to maize, which is very important in accounting for pests and predicting their appearance on the maize crops. You can learn about their presence by the nature of the damage they cause. Knowledge of the biology of helicoverpa zea and other dominant pests makes it possible to correctly plan and carry out protective measures in a timely manner. In order to successfully suppress pests, you have to know their biology and developmental features. Plant protection researchers carry out registration and prognosis of the maize phytophages and establish geographical distribution of their most important ones, like cotton bedworm (Helicoverpa armigera Hbn.). Zones of the most harm are determined. This makes it possible to rationally plan the measures for suppressing this danger. The scientists of the Institute are faced with the task of constantly improving the developed integrated pest control systems in relation to certain zones of the republic. These systems should be based on skillful and widespread use of advanced agricultural technology and highyielding zoned varieties, and on a reasonable combination of chemical and biological methods of protection. Much attention is paid to biological methods of suppressing helicoverpa zea, the use of which can significantly reduce the numbers of the pests’ caterpillars, and reduce the consumption rate of chemicals, and improve the quality of the crop as well as the hygienic condition of the maize grains.
