Soil-derived bacteria endow Camellia weevil with more ability to resist plant chemical defense.

ABSTRACT:

Background

Herbivorous insects acquire their gut microbiota from diverse sources, and these microorganisms play significant roles in insect hosts' tolerance to plant secondary defensive compounds. Camellia weevil (Curculio chinensis) (CW) is an obligate seed parasite of Camellia oleifera plants. Our previous study linked the CW's gut microbiome to the tolerance of the tea saponin (TS) in C. oleifera seeds. However, the source of these gut microbiomes, the key bacteria involved in TS tolerance, and the degradation functions of these bacteria remain unresolved.

Results

Our study indicated that CW gut microbiome was more affected by the microbiome from soil than that from fruits. The soil-derived Acinetobacter served as the core bacterial genus, and Acinetobacter sp. was putati
