In this study, the genetic diversity and phylogenetic relationships of Eurygaster austriaca (Schrank) samples collected from various agrocenoses in Uzbekistan were investigated. Analysis of mtCOI gene revealed nucleotide differences ranging from 0.2% to 1%, indicating genetic closeness and stability among these populations. A phylogenetic tree was constructed which revealed that E. austriaca samples formed a distinct cluster different from E. maura (BS = 100), E. amerinda (BS = 96-97), and E. testudinaria (BS = 79-94). Genetic distance analysis showed low intraspecific divergence within E. austriaca populations (0.0022-0.0139) and significant interspecific differences (e.g., between E. austriaca and E. testudinaria, 0.1250-0.1317). The Ch. fallax sample stood apart from all others, displaying the highest genetic distance (1.0947-1.1824), indicating its affiliation with a separate evolutionary lineage.
