This article presents a literature-based review of the population and bioecological characteristics of the major trematode pathogens affecting cattle in the agroecosystems of the Fergana Valley, including Fasciola hepatica, Fasciola gigantica, Paramphistomum spp. and Dicrocoelium dendriticum. The life cycles of the trematodes, their intermediate hosts, their adaptation to environmental factors and the patterns of their distribution within agroecosystems were analysed. The climatic and hydrological conditions of the Fergana Valley were found to have a significant influence on the epizootiological processes of trematode infections.

В статье на основе анализа научной литературы рассмотрены популяционно-биоэкологические особенности основных возбудителей трематодозов крупного рогатого скота, распространённых в агроэкосистемах Ферганской долины, включая Fasciola hepatica, Fasciola gigantica, Paramphistomum spp. и Dicrocoelium dendriticum. Проанализированы жизненный цикл трематод, их промежуточные хозяева, адаптация к экологическим факторам и закономерности распространения в агроэкосистемах. Установлено, что климатические и гидрологические условия Ферганской долины оказывают существенное влияние на эпизоотологические процессы трематодозов.

Maqolada Farg‘ona vodiysi agroekotizimlarida qoramollarda uchraydigan asosiy trematodoz qo‘zg‘atuvchilari — Fasciola hepatica, Fasciola gigantica, Paramphistomum spp. va Dicrocoelium dendriticum ning populyatsion-bioekologik xususiyatlari adabiyotlar tahlili asosida yoritilgan. Trematodalarning rivojlanish sikli, oraliq xo‘jayinlari, ekologik omillarga moslashuvi hamda agroekotizimlarda tarqalish qonuniyatlari tahlil qilingan. Farg‘ona vodiysining iqlim va gidrologik sharoitlari trematodozlarning epizootologik jarayonlariga sezilarli ta‘sir ko‘rsatishi aniqlangan.
