Hamiltonella defensa

Pseudomonadota

Bacteria

attenuate the systemic release of volatiles by plants after aphid attack, reducing parasitic wasp recruitment and increasing aphid fitness.

2017

Hamiltonella defensa

Pseudomonadota

Bacteria
Intracellular

aphid larvae become darker green when co-infected with Rickettsiella viridis and Hamiltonella defensa

2015

Bacteria
Intracellular

Provides resistance to certain parasitic wasps, such as Aphidius

2015

Bacteria
Intracellular

the genome of Hamiltonella revealed that this secondary symbiont can not only provide vitamins and cofactors, but also complete the missing steps of some of the pathways of Portiera

2015

Bacteria
Intracellular

symbiont provided strong protection against L. fabarum and Aphidius colemani, but there was no evidence that H. defensa-infected aphids were more resistant to the other parasitoid species

Hamiltonella defensa

Pseudomonadota

Bacteria
Intracellular

mediates whitefly–plant interactions by suppressing induced plant defences in tomato

Bacteria
Intracellular

confers protection against parasitoid wasps

Hamiltonella defensa

Pseudomonadota

Aphis fabae

Hemiptera

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

Hamiltonella defensa

Pseudomonadota

Bacteria

2012

Bacteria

can block larval development of the solitary endoparasitoid wasps Aphidius ervi and Aphidius eadyi, rescuing the aphid hos

2009

Hamiltonella defensa

Pseudomonadota

Bacteria
Intracellular

kills parasitoid wasp larvae, allowing aphid hosts to survive and reproduce

2008

Bacteria
Intracellular

provides protection against parasitism by the wasp, Aphidius ervi

2008

Bacteria

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

2005

Hamiltonella defensa

Pseudomonadota

Bacteria

source of resistance to A. ervi is infection by the facultative bacterial symbiont Hamiltonella defensa
