Laboratory-reared and field-collected P. chrysocephala all contained three core genera Pantoea, Acinetobacter and Pseudomonas, and reintroduction of Pantoea sp. Pc8 in antibiotic-fed beetles restored isothiocyanate degradation ability in vivo (by 16S rRNA gene sequencing and LC-MS)

Larvae developed in unripe olive harbored more E. dacicola (by 16S rRNA gene sequencing)

Abundance of genus Pseudomonas in D. superans larvae increased, but Serratia and Enterobacter decreased, and L. dispar larvae fed on aconitine-treated diet and nicotine-treated diet shared dominant bacteria Enterococcus (by 16S rRNA gene sequencing)

Laboratory-reared and field-collected P. chrysocephala all contained three core genera Pantoea, Acinetobacter and Pseudomonas, and reintroduction of Pantoea sp. Pc8 in antibiotic-fed beetles restored isothiocyanate degradation ability in vivo (by 16S rRNA gene sequencing and LC-MS)

R. aquatilis decreased (−)-α-pinene (38%) and (+)-α-pinene (46%) by 40% and 45% (by GC-MS), respectively

Genera contained most genes involved in terpene degradation (by metagenomics)

Degraded 20–50% of α-pinene (by GC-MS)

S. marcescens reduced 49–79% of 3-carene and (−)-β-pinene

Genera contained most genes involved in terpene degradation (by metagenomics)

Degraded 20–50% of α-pinene (by GC-MS)

Acinetobacter sp. in C. chinensis enriched after treating with saponin, and when incubating bacteria with saponin for 72 h, saponin content significantly decreased from 4.054 to 1.867 mg/mL (by 16S rRNA metagenome sequencing and HPLC)

showed significant volatile inhibition activity against fungal entomopathogen Fusarium moniliforme, Botryosphaeria dothidea and both Fusarium oxysporum respectively

aphid endosymbiont Buchnera aphidicola can facilitate cucumber mosaic virus (CMV) transmission by modulating plant volatile profiles

shown to be highly abundant in a specific portion of the gut and necessary for the host development
