Evaluation of corn resistance to the Asian corn borer Ostrinia furnacalis (Guenee, 1854) in the conditions of the southern Far East

Recently, the production of grain corn has increased significantly in the Primorsky Territory. When growing corn, agricultural producers have noted the high harmfulness of the Asian corn borer Ostrinia furnacalis (Guenee, 1854). This pest is polyphagous but causes the most damage to corn plants (Zea mays L.). The caterpillars feed inside the plant, which creates the problem of protecting the crop with insecticides. In this regard, one of the radical measures to combat Ostrinia furnacalis Gn. is the creation of resistant varieties, lines and hybrids of corn. Resistant varieties are able to contain the pest population and maintain productivity even when they are significantly damaged. The objective of this study was to establish the true resistance of the specimen against an artificial background of colonization of corn plants with phytophage eggs, since in selection the assessment of Zea mays L. for resistance to pests is carried out using provocative and artificial backgrounds. Evaluation of nine promising breeding samples of corn was carried out for their resistance to Ostrinia furnacalis (Guenee, 1854): 3015, 3016, 3019, 3092, 3147, 3195, 3271, 3274, 3278. These samples were previously isolated from the Zea mays L. breeding nursery as resistant to natural pest infestation. Two components of corn resistance to the Aisian corn borer were studied: plant antibiosis and their tolerance to damage. Each indicator of plant resistance to the pest is characterized. As a result of the studies, two lines of corn (3147 and 3271) with average stem resistance (2.1 and 2.9 points, respectively) and high tolerance were identified. Five hardy samples of Zea mays L. were also found. The studied material is recommended for inclusion in the selection process.
