Effect of Modern Drugs to Some Biophysiological Properties
of Sunflower Pests (Homoesoma Nebulella)
Abstract
One of the most widespread and leading pests in sunflower fields due to the damage it causes is the sunflower weevil, which belongs to the order of Lepidoptera. The distribution of this species in the fields is 46.3%, and its caterpillars have been found to damage 37-39% of the seeds in the baskets of the plants. Other representatives of the order, accounting for 13-18% of the total distribution, damage the plants by 13-30%. Studies conducted in 2023-2024 show that 20-25% of the sunflower crop's productivity is reduced annually by its dangerous pest, the sunflower moth (Homoesoma nebulella Hb.). From this, the great economic importance of the sunflower weevil is clearly evident. Therefore, we considered it appropriate to study the bioecological characteristics, development dynamics, and economic damage threshold of this pest in more detail, and to clarify the effectiveness of various preparations against it.
