Endosymbiotic bacteria of A. craccivora collected from two different host plants
To investigate whether symbiont infection is structured by host plant in the polyphagous aphid Aphis craccivora Koch, 454 pyrosequencing was performed on pooled aphid populations from two different host plants, alfalfa (Medicago sativa) and black locust (Robinia pseudoacacia). Results indicated that Aphis craccivora harbors distinctly different microbial communities in alfalfa versus locust. The facultative symbiont Hamiltonella was found only in aphids collected from alfalfa, and the facultative symbiont Arsenophonus was found only in aphids from locust.
