Abstract
Ushbu maqolada 2022-2025 yillarda Farg‘ona vodiysining turli hududlarida o‘tkazilgan dala kuzatuvlari asosida invaziv hasharotlar va ularning ozuqa o‘simliklari o‘rtasidagi trofik aloqalar ekologik jihatdan tahlil qilindi. Tadqiqotlar davomida 24 ta o‘simlik oilasi, 83 ta o‘simlik taksoni va 26 ta invaziv kompleks bo‘yicha jami 256 ta trofik aloqa o‘rganildi. Oilalar kesimida invaziv bosim notekis bo‘lib, ayrim xo‘jalik ahamiyatli oilalarda komplekslar soni yuqori darajada to‘plandi. Trofik nishalar funksional gildiyalarga ajratilganda sanchib-so‘ruvchi fitofaglar ulushi (43,4%) yetakchi bo‘lib, barg fitofaglari (24,6%) va poya-novda zararkunandalari (11,3%) keyingi o‘rinlarni egalladi. Keng polifag yondashuvida polifag komplekslar bilan bir qatorda tor doirali (1 oila bilan cheklangan) komplekslar ham mavjudligi aniqlandi. Natijalar asosida qishloq xo‘jaligi ekinlariga qarshi kurash va fitokarantin nuqtayi nazaridan amaliy tavsiyalar ishlab chiqildi
