Bacteria
Intracellular

when faced with hosts possessing H. defensa, aphid parasitoids are under selection to preferentially attack the youngest host stages and/or to discriminate against symbiont-protected aphids; suggest a high specificity of symbiont-conferred resistance

the effects of attack by parasitoid wasps are ameliorated by infection with H. defensa: the wasp larva dies prematurely, allowing the aphid host to develop to the adult stage and to reproduce
