One of the main reasons for the increase in the number of xylophagous insects is the fact that almost the majority of the territory of the Southern Aral Sea region by geographic location consists of sandy-desert territories. Many historical and cultural objects of the republic were built on these territories. The occurrence of xylophagous insects in natural habitats of the Southern Aral Sea region varied depending on the location of tugai farms. In total, 24.2% of xylophagous insects belonging to 9 orders, 24 families were found in the tugai farms of the Southern Aral Sea region and 100% of the species belonging to the aforementioned group and family in the Nizhne-Amudarya State Biosphere Reserve.
