AB  - Microbial communities associated with animals vary based on both intrinsic and 
      extrinsic factors. Of many possible determinants affecting microbiome 
      composition, host phylogeny, host diet, and local environment are the most 
      important. How these factors interact across spatial scales is not well 
      understood. Here, we seek to identify the main influences on microbiome 
      composition in a specialist insect, the western corn rootworm (WCR; Diabrotica 
      virgifera virgifera), by analyzing the bacterial communities of adults collected 
      from their obligate host plant, corn (Zea mays), across several geographic 
      locations and comparing the patterns in communities to its congeneric species, 
      the northern corn rootworm (NCR; Diabrotica barberi). We found that bacterial 
      communities of WCR and NCR shared a portion of their bacterial communities even 
      when collected from disparate locations. However, within each species, the 
      location of collection significantly influenced the composition of their 
      microbiome. Correlations of geographic distance between sites with WCR bacterial 
      community composition revealed different patterns at different spatial scales. 
      Community similarity decreased with increased geographic distance at smaller 
      spatial scales (~25 km between the nearest sites). At broad spatial scales 
      (>200 km), community composition was not correlated with distances between sites, 
      but instead reflected the historical invasion path of WCR across the United 
      States. These results suggest bacterial communities are structured directly by 
      dispersal dynamics at small, regional spatial scales, while landscape-level 
      genetic or environmental differences may drive community composition across broad 
      spatial scales in this specialist insect.
