Abstract
In the conditions of Tashkent and Samarkand provinces of Uzbekistan, autumn moth ( Agrotis segetum Den. Et Sshiff ) is one of the most common pests in irrigated agricultural areas. The worms of this pest damage hundreds of crops belonging to 34 families and infect cotton, alfalfa, sugar beet, corn, cereals, legumes, oilseeds and vegetables, melons and potatoes, as well as ivy, wild coconut, sorghum, and oats. Autumn nocturnal worms pierce the seed pods, damaging the root collar of young sprouting crops. The developmental characteristics of underground pests of potatoes planted in the post-grain recurrence period were studied, their bioecology according to the characteristics of damage to various crops.
