    Nowadays, global climate change is leading to the widespread distribution of bird ectoparasites, specifically mites of the Dermanyssidae family, and an increase in their harmful effects. This has caused a sharp decline in poultry farming development and productivity. Therefore, studying the bioecology of bird ectoparasites and developing new methods to protect poultry from them is a pressing issue. During the spring, summer, and autumn of 2022-2023, acarological examinations were conducted to identify infestations of Dermanyssus gallinae (red poultry mites) in poultry farms and household flocks across 25 locations in the Dehqonobod, Kasbi, Kitob, Koson, and Mirishkor districts of the Kashkadarya region, Uzbekistan. In the research, 457 Gallus gallus domesticus (chickens) were examined using both route and stationary methods, and 1,700 mite specimens belonging to the Dermanyssidae family were collected. The species composition and morpho-biological characteristics of Dermanyssus gallinae were analyzed. Molecular genetic studies were conducted on D. gallinae , focusing on the mitochondrial DNA 16S rRNA region, and the nucleotide sequences were analyzed. The obtained sequences were compared with those in the NCBI database. Additionally, the phylogenetic tree of species belonging to the Dermanyssus genus was studied.
