Bacterial symbionts are prevalent in arthropods globally and play a vital role in the fitness and resistance of hosts. While several symbiont infections have been identified in the white-backed planthopper Sogatella furcifera, the impact of environmental factors on the microbiota within remains elusive.
In this study, a total of 142 S. furcifera individuals from 18 populations were collected from 14 locations across six countries (China, Thailand, Myanmar, Cambodia, Vietnam, and Laos) analyzed with 2bRAD-M sequencing, to examine the effects of symbionts on the microbiota in the population, as well as the vital effects of environmental factors on the bacterial communities.
Based on the results, in , the presence of symbionts Wolbachia and Cardinium negatively influenced the abundance of other bacteria, including Enterobacter, Acinetobacter, and Lysinibacillus, while Wolbachia infection significantly decreased the diversity of the microbial community. Moreover, several environmental factors, including longitude, latitude, temperature, and precipitation, affected the abundance of symbionts and microbiota diversity in . These results collectively highlight the vital role of Wolbachia in microbiota, as well as the intricate effects of environmental factors on the bacterial communities of .
细菌共生体在全球节肢动物中普遍存在，对宿主的健康和抵抗力起着至关重要的作用。虽然在白背飞虱中已鉴定出几种共生体感染，但环境因素对其体内微生物群的影响仍不清楚。
在本研究中，从中国、泰国、缅甸、柬埔寨、越南和老挝六个国家的14个地点收集了来自18个种群的总共142只白背飞虱个体，用2bRAD-M测序进行分析，以研究共生体对该种群微生物群的影响，以及环境因素对细菌群落的重要影响。
基于结果，在白背飞虱中，共生体沃尔巴克氏体和卡丁氏菌的存在对包括肠杆菌、不动杆菌和赖氨酸芽孢杆菌在内的其他细菌的丰度产生负面影响，而沃尔巴克氏体感染显著降低了微生物群落的多样性。此外，包括经度、纬度、温度和降水在内的几个环境因素影响了白背飞虱中共生体的丰度和微生物群多样性。这些结果共同突出了沃尔巴克氏体在白背飞虱微生物群中的重要作用，以及环境因素对白背飞虱细菌群落的复杂影响。
