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.
Highlights
It is urgent to develop effective and fundamentally based control measures against agricultural pests in the world in order to preserve the lost crops
In the potato field, which was planted on June 15, 2017 and fully germinated on July 1, sexual pheromone traps of autumn and fallow moth were installed and the flight of pest butterflies was taken into account
While the number of moths was 2.1 per day, our observations showed a slight decrease to 10 days (0.1) (Table 1)
Summary
It is urgent to develop effective and fundamentally based control measures against agricultural pests in the world in order to preserve the lost crops. As a result of damage to the root system and sprouted grasses of legumes, vegetables and potatoes during the young growing season due to the damage of underground pests in Uzbekistan, the seedlings are in conflict and cause the death of the plant This leads to a sharp decrease in yield and deterioration of product quality [1]. As a result of damage by root rodent pests, legumes, vegetables and potato crops damage the root portion and sprouted grasses during the young germination period, causing the seedlings to clash and the plant to die This leads to a sharp decrease in yield and deterioration of product quality [10, 11].
