Serratia symbiotica explained

Serratia symbiotica is a species of bacteria that lives as a symbiont of aphids.^[1] In the aphid Cinara cedri, it coexists with Buchnera aphidicola, given the latter cannot produce tryptophan.^[2] It is also known to habitate in Aphis fabae.^[3] Together with other endosymbionts, it provides aphids protection against parasitoids.
