Abstract:
:Gut microbiota has been suggested as an important component of host defense. However, microbiota in other parts of the body have rarely been characterized. In our present work, we give a detailed view of the body of Spodoptera exigua larvae, the midgut with intestinal contents (MG), midgut excluding intestinal contents (PM), intestinal contents (IC) and remaining parts excluding the MG (RM), with the objective of revealing the complexity of microorganisms and comparing the biodiversity of the S. exigua larvae-associated microbiota. Our results provide the first evidence that third and fifth larvae samples of S. exigua were dominated by members of the phyla Firmicutes and Proteobacteria. In addition, there were no obvious differences in relative abundances of microbiota among MG, PM and RM at the phylum level. MG3 and MG5 (nearly RM5) harbored the richest microbial community, with much higher abundance of Halomonas, Pseudomonas and Methylobacterium, respectively. Intestinal contents contained the lowest diversity and highest abundance of Enterococcus. Knowledge of the bacteria in a major herbivorous insect, such as S. exigua, can facilitate the acquisition of special biological resources for agricultural pest control.
