Diversity and Influencing Factors of Endosymbiotic Bacteria in Tetranychus truncatus Sourced from Major Crops in Xinjiang

Year: 2025

Type: article

Abstract: The Xinjiang Uygur Autonomous Region, situated in northwest China, boasts a unique geographical position and a consequent variety of environmental characteristics. T. truncatus is prevalent throughout this region as the primary pest affecting various crops. In this study, we analyzed the microbial community structures of endosymbiotic bacteria in T. truncatus collected from 17 regions and three host plants in Xinjiang using 16S rRNA sequencing. Through composition analysis of the endosymbiotic bacteria in T. truncatus from Xinjiang, it was found that the dominant bacterial phyla were Pseudomonadota and Bacillota. At the genus level, in addition to Wolbachia, Cardinium, and Spiroplasma (common symbiotic bacteria in T. truncatus), the infection rate of Rickettsia in T. truncatus in Xinjiang was found to be 92.8%. The diversity of the endosymbiotic bacteria community in T. truncatus is shaped by both host plant species and geographical region. Specifically, the endosymbiotic bacterial diversity in T. truncatus populations on corn was significantly higher than that observed in populations on cotton and soybean (p < 0.05). Furthermore, we discovered the diversity of endosymbiotic bacteria in T. truncatus was significantly higher in southern Xinjiang than in northern Xinjiang (p < 0.05).
