Abstract The honey bee Apis cerana plays a significant role in maintaining ecosystem stability through its involvement in pollinating over 500 species of both wild and cultivated plants. Due to its high ecological plasticity, this species is widely distributed across diverse climatic zones, ranging from the tropical regions of Vietnam to the sharply continental areas of Russia’s Primorsky Krai. Under anthropogenic pressures such as urbanization and habitat degradation, the study of the genetic diversity and adaptive potential of A. cerana becomes increasingly important. In this study, polymorphism of the orcokinin A gene (OK-A)—a neuropeptide involved in the regulation of physiological and behavioral responses in bees—has been analyzed. Nucleotide sequences of the OK-A gene were obtained from worker individuals collected from 45 bee colonies representing A. cerana populations from Russia (A. c. ussuriensis), South Korea (A. c. koreana), and Vietnam (A. c. indica). These populations have been shaped by differences in geographic and climatic conditions as well as by genetic-stochastic processes. The OK-A gene showed moderate levels of polymorphism: ten allelic variants were identified among the 45 samples, including two nonsynonymous substitutions within exonic regions (73 tv A/C and 359 ts A/G) and eight variations located in intronic regions. Results of Tajima’s neutrality test (D = –1.90, p < 0.01) suggest possible effects of purifying selection, which may indicate functional significance of the studied gene. The analysis of genetic distances (p-distance) revealed low levels of intraspecific divergence among A. cerana populations (0.004–0.006), whereas interspecific divergence compared to other Apis species, specifically A. mellifera, A. dorsata, and A. florea, was considerably higher (0.097–0.157). Phylogenetic analysis confirmed clear species separation and partial differentiation among A. cerana populations. Some of the identified nucleotide variations, particularly at positions 142 tv (C/G) and 423 tv (G/T), exhibited high discriminatory power and could serve as potential markers for population identification.
