摘要蜘蛛类常与多种内共生菌共生，其感染模式往往表现出时空变异。然而，内共生菌流行与环境因素之间的关系尚不清楚。本文对中国地区元宝山叶螨自然种群内共生菌进行了调查，共筛选出21个地点12种寄主植物的935只叶螨。在不同的感染频率(分别为52.5%、26.3%和8.6%)下，共检出3种兼性内共生菌谱系：沃尔巴克氏菌、卡氏杆菌和螺旋体。在大多数当地人群中观察到了多种内共生菌感染，从人群中每种感染的频率来看，沃尔巴克氏杆菌和螺旋体混合感染的个人发病率高于预期。内共生菌感染频率与环境因素相关：沃尔巴克氏菌感染率在年平均气温较高的地区增加，而卡氏杆菌和螺旋体感染率在海拔较高的地区增加。与玉米相比，沃尔巴克氏菌在番茄和大豆中更常见。这项研究强调，宿主-内共生菌的相互作用可能与环境因素有关，包括气候和其他地理上相关的因素，以及宿主的食用植物。重要性这项研究的目的是调查蜘蛛体内内共生菌的分布和感染模式。主要发现是多重内共生菌感染比预期更常见，内共生菌感染频率与环境因素有关。这项工作强调了宿主-内共生菌的相互作用需要在环境和地理背景下进行研究。
ABSTRACT Spider mites are frequently associated with multiple endosymbionts whose infection patterns often exhibit spatial and temporal variation. However, the association between endosymbiont prevalence and environmental factors remains unclear. Here, we surveyed endosymbionts in natural populations of the spider mite, Tetranychus truncatus, in China, screening 935 spider mites from 21 localities and 12 host plant species. Three facultative endosymbiont lineages, Wolbachia, Cardinium, and Spiroplasma, were detected at different infection frequencies (52.5%, 26.3%, and 8.6%, respectively). Multiple endosymbiont infections were observed in most local populations, and the incidence of individuals with the Wolbachia-Spiroplasma coinfection was higher than expected from the frequency of each infection within a population. Endosymbiont infection frequencies exhibited associations with environmental factors: Wolbachia infection rates increased at localities with higher annual mean temperatures, while Cardinium and Spiroplasma infection rates increased at localities from higher altitudes. Wolbachia was more common in mites from Lycopersicon esculentum and Glycine max compared to those from Zea mays. This study highlights that host-endosymbiont interactions may be associated with environmental factors, including climate and other geographically linked factors, as well as the host's food plant. IMPORTANCE The aim of this study was to examine the incidence of endosymbiont distribution and the infection patterns in spider mites. The main findings are that multiple endosymbiont infections were more common than expected and that endosymbiont infection frequencies were associated with environmental factors. This work highlights that host-endosymbiont interactions need to be studied within an environmental and geographic context.
