The first individuals of western corn rootworms (Diabrotica virgifera virgifera Le Conte) were noticed in the border zone of Transcarpathia region in 2001. These insect pests had inhabited only two regions of the country for a long period of time. However, the gradual spread of Diabrotica species from the places of the first detection to the South and West of Ukraine has been noticed recently. The main aim of the research is to study the spreading tendency of the western corn rootworms (WCR) in the Ukrainian forest-steppe zone and to create the preventative system for identifying insect pest localization and extermination. According to the research results, it has been determined that the population of insect pests is increasing every year. There is a plant-feeding insect adaptation due to corn cultivation increase, poor crop rotation and climate change. The research priority and relevance has been done on the basis of the interest in insect pest identification, studying of their biological spread peculiarities under the consideration of modern conditions and improving of the insect pest control preventative methods.
