Similarities and spatial variations of bacterial and fungal communities in field rice planthopper (Hemiptera: Delphacidae) populationsh

This study investigated the bacterial and fungal community compositions of Chinese wil d rice planthoppersLaodelphax striatellus andSogatella furcifera using parallel 16S rRNA gene amplicon and internal transcribed space region sequencing. The bacteria varied significantly between the species and were partitioned significantly by sexes, tissues and host environments in each species. The majority of bacteria were affiliated with the generaWolbachia,Cardinium,Rickettsia andPantoea. The abundance ofWolbachia was negatively correlated with that ofCardinium in both planthopper species. Compared with bacteria, the abundance and diversity of fungi did not differ between sexes but both were enriched in the gut. The bacterial community as a whole showed no significant correlation with the fungal community. The majority of fungi were related toSarocladium,Alternaria,Malassezia,Aspergillus andCurvularia. A phylogenetic analysis revealed that these fungi were closely related to botanic symbionts or pathogens. Our results provide novel insights into the bacteria and fungi of rice planthoppers.This article is protected by copyright. All rights reserved
