Maqolada iqlim o‘zgarishining O‘zbekiston Respublikasidagi qishloq xo‘jaligi zararkunandalariga,
xususan, g‘o‘za tunlami (Helicoverpa armigera) populyatsiyasiga ta’siri o‘rganildi. 1901–2024 yillardagi o‘rtacha
harorat ma’lumotlari asosida statistik tahlil o‘tkazilib, haroratning oshishi bilan zararkunandalarning avlodlar soni
ortib borishi aniqlangan. 2024–2050 yillarga mo‘ljallangan prognozlarga ko‘ra, global isish davom etsa, g‘o‘za tunlamining
avlodlar soni 3,5 dan 5,3 gacha ko‘payishi mumkin. Bu tendensiya qishloq xo‘jaligiga salbiy ta’sir ko‘rsatib,
o‘simliklarni himoya qilish chora-tadbirlarini takomillashtirish zarurligini ko‘rsatadi.

В данной статье исследовано влияние изменения климата на сельскохозяйственных вредителей
в Республике Узбекистан, в частности на популяцию хлопковой совки (Helicoverpa armigera). На основе данных о
средней температуре за период 1901–2024 годов проведен статистический анализ, который показал увеличение
числа поколений вредителей с ростом температуры. Согласно прогнозам на 2025–2050 годы, при продолжении
глобального потепления число поколений хлопковой совки может возрасти с 3,5 до 5,3. Эта тенденция указывает
на негативное воздействие на сельское хозяйство и необходимость совершенствования мер защиты растений.

This article examines the impact of climate change on agricultural pests in the Republic of Uzbekistan, with a
focus on the cotton bollworm (Helicoverpa armigera) population. Based on average temperature data from 1901 to 2024, a
statistical analysis was conducted, revealing an increase in the number of pest generations with rising temperatures. Forecasts
for 2025–2050 suggest that, if global warming continues, the number of cotton bollworm generations could rise from 3,5 to
5,3. This trend highlights a negative impact on agriculture and underscores the need to improve plant protection measures.
