Our research works have been in north and south districts of Surkhandaya region, South Uzbekistan in between 2017-2019. Damage to the cotton crop of cotton shredder bug was carried out in special entomologic cages at different times. The experiments were conducted in the Bukhara-102 cotton variety which was planted in 90 cm rows. Special entomologic cages are 120 cm X 120 cm X 120 cm and it puts to 10 cotton plants Adult cotton shredder bugs were placed at 0 (cultivation time of cotton), 10, 30, 50 (early), and 0 (control), 3, 5, and 10 in cultivation late time of the plant. In experiments, the reduction of cotton yield relative to the control was calculated at each decade of the month. According to the results of the study, Creontiades pallidus increased in the number of cotton during early shading caused the reduction of cotton yield by 62.5, 89.6, 94.8% compared to the control, and by 12.5, 26.9, 34.9%. Creontiades pallidus is widely multiplied on cotton fields near of the Amu Darya, and in July-August the number ranges from 500 to 1000 insects per 100 plants.
