Bacteria

Mammaliicoccus sciuri produces the secreted chitinolytic lysozyme Msp1, which damages fungal cell walls and completely inhibits the spore germination of the fungal entomopathogens Metarhizium robertsii and Beauveria bassiana.

Bacteria

The silkworm microbiome contains genes that encode functions, such as the chitinolytic lysozyme Msp1, that confer antimicrobial activity against fungal entomopathogens.

Microbacterium

Actinomycetota
Bacteria
Extracellular

In host larvae, Microbacterium could contribute to the balance and resiliency of the gut microbiome under stress conditions. In addition, Rhodococcus was found in host larvae and is known for its detoxification capabilities

Burkholderia

Pseudomonadota
Bacteria
Extracellular

Burkholderia is commonly found in the gut of Coccinella septempunctata and may exhibit nitrogen fixation abilities and trigger the expression of disease resistance genes.

Methylovirgula

Pseudomonadota
Bacteria
Extracellular

Methylovirgula is associated with carbon activity and has been found to be a major species producing carbon activity in soil systems.

Rhodobacter

Pseudomonadota
Bacteria
Extracellular

Rhodobacter (Rhodanobacter genera) can utilize various carbon sources, including cellobiose, and may aid Coccinella septempunctata in digesting carbon nutrients.

Bacteria and Fungi
Intracellular

Serratia is rich in the long-winged Nilaparvata lugens and is speculated to help the host adapt to harsh environments, potentially related to virulence variation.
Developmental Modulation

Pantoea dispersa

Pseudomonadota
Bacteria
Intracellular and Extracellular

Pantoea dispersa acts as a probiotic for the fall armyworm (Spodoptera frugiperda), helping to detoxify benzoxazinoids (maize secondary metabolites) and promote caterpillar growth.
Detoxification Enzymes

Acetobacter

Pseudomonadota
Bacteria
Extracellular

Acetobacter (as part of the gut microbiome) enhances the brain levels of tyrosine decarboxylase 2 (Tdc2), an enzyme that synthesizes the neuroactive substance octopamine (OA), thereby promoting larval locomotion in Drosophila melanogaster.
