FAUNA AND ECOLOGY OF THE TRUE GRASSHOPPERS (ORTHOPTERA: ACRIDIDAE) OF EASTERN FERGANA

Abstract

In this article, a wide scientific analysis of the fauna and ecology of true grasshoppers (Orthoptera: Acrididae) distributed in the eastern Fergana region was carried out. The study was carried out in 2021-2024 in different landscape zones of the Fergana Valley, with a total of 27 species identified. Grasshopper species have been classified into ecological groups and their distribution, seasonal population dynamics, and environmental factor effects have been studied.nnotation: in this article, a wide scientific analysis of the fauna and ecology of true grasshoppers (Orthoptera: Acrididae) distributed in the eastern Fergana region was carried out. The study was carried out in 2021-2024 in different landscape zones of the Fergana Valley, with a total of 27 species identified. Grasshopper species have been classified into ecological groups and their distribution, seasonal population dynamics, and environmental factor effects have been studied. The results showed that species belonging to the xerophilous, mesophilous, hygrophilous, and agrophilous groups are closely linked to the landscape conditions of the region. It has been confirmed that temperature, humidity and anthropogenic factors play an important role in annual and seasonal fluctuations in population numbers. This research provides a scientific basis for improving the monitoring system of eastern Fergana grasshoppers and measures to combat pests in agricultural ecosystems.
