Escherichia coli

Pseudomonadota
Bacteria
Extracellular

Escherichia coli may produce the semiochemical 4,8-dimethyldecanal (DMD), which is strongly associated with female attraction and host pheromone communication in Tribolium castaneum.

Enterobacter

Pseudomonadota
Bacteria
Extracellular

Enterobacter (as part of a probiotic consortium) significantly influences the intestinal microbiota structure, leading to improved functional potential and increased carbohydrate-active enzymes (CAZymes) in Ceratitis capitata.

Serratia

Pseudomonadota
Bacteria
Extracellular

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.

Serratia symbiotica

Pseudomonadota
Bacteria
Intracellular

Serratia symbiotica improves the host aphid (Acyrthosiphon pisum) growth and fecundity while reducing longevity. It also provides defense against the predator P. japonica by impeding the predator's development and modulating its foraging behavior.

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.
