On the invasion of the Western corn rootworm (Diabrotica virgifera virgifera Le Conte) in Belarus
Abstract
Western corn rootworm is included in the Unified List of quarantine objects of the Eurasian Economic Union. To detect the invasion in Belarus, more than 7 000 hectares of corn crops are controlled. According to pheromone monitoring, the first invasion of the Western corn root worm has been recorded in 2009. Since 2011, foci of invasion have been recorded annually. In 2019, 11 outbreaks have been identified, including 5 outbreaks in the Grodno region. The beetle invades corn crops located along the border with Poland and Ukraine and the Brest – Minsk highway. Over 10 years, foci of invasion have been recorded at a distance of 180–200km along the highway. The main factors contributing to the Western corn rootworm invasion are the territorial location of farms along the borders with the Ukraine and Poland, the cultivation of corn over a large area without crop rotation, spatial isolation in the quarantine zone. Considering the prevailing weather conditions in Belarus, the biology and ecology of the Western corn root warm, the spread of the quarantine pest in the northern and eastern directions is predicted. Only with the strict observance of the recommendations for quarantine, agrotechnical and chemical measures, itis possible to prevent the formation of permanent foci of the Western corn rootworm.
