Genetic diversity of seven-spotted ladybug populations in Iran using cytochrome oxidase gene analysis

Lady beetles, particularly the seven-spotted lady beetle, play an essential role as biological control agents against aphids and other pests in agricultural ecosystems. Studying their molecular biology can provide insights into their adaptation, behavior, and potential for pest control. Recent progress in genomic technologies has led to a better understanding of the molecular mechanisms involved in these processes. In this study, we examined the genetic structure of Iranian populations of this species by sequencing the cytochrome oxidase gene. Analysis of thirty-three genetic sequences (positions ۱-۵۷۶) showed a haplotype diversity of ۰.۹۴۵, with ۲۵ distinct haplotypes identified. The nucleotide diversity was relatively low (π = ۰.۰۰۶۵۸), revealing a discrepancy between haplotype diversity and nucleotide diversity. This pattern suggests the presence of a genetically diverse population with conserved genomic regions, likely resulting from recent population expansion or selective pressures. Our findings provide important information about population dynamics and offer valuable insights for conservation strategies and ecological planning.
