ABSTRACT. A comparison of orthopteran assemblage distribution in the Hissar Valley was made for two periods, namely, the 1930s and the end of the 20th century - beginning of the 21st century. Anthropogenic factors that influenced the assemblage transformation are revealed. The irrigation changes are among the most important factors. The abundance and local distribution of Orthoptera depend on environmental alterations, especially those resulting from agrotechnical treatments. The local modern assemblages are rather uniform and include a few species that usually actively populate transformed ecosystems. They are distinguished by dynamic changes, the nature of which is determined not so much by seasonality and long-term changes but rather by very rapid changes in human activity.
