Characteristics of 10 collection sites and 16S rRNA gene sequence clone libraries and species richness estimates.

aPopulation was named according to the abbreviation of the province or municipality where they were collected.bCrop grown at the field where Holotrichia parallela larvae were collected.cNumber of clones isolated from the host population.dNumber of representative clones that were chosen and sequenced.eNumber of OTUs identified in the 16S rRNA gene clone library. OTUs were defined based on 3% sequence divergence.flibrary coverage calculated by the equation C = (1−n/N)*100, where n is the number of unique clones and N is the total number of clones examined.
