...These effects are commonly beneficial to the host, as in the case of H. defensa, which uses a bacteriophage-encoded mechanism to protect its host against parasitoid wasp larvae, thereby enabling its own survival and transmission (Oliver et al., 2010)....

...Interestingly, Rickettsiella is often found in concert with Hamiltonella or Serratia, those aphids that confer protection against parasitoid wasps (Oliver et al., 2010; Tsuchida et al., 2010)....

...More and more traits can now be correlated with the presence of the often less well characterised secondary symbionts (Teixeira et al., 2008; Brownlie & Johnson, 2009; Oliver et al., 2010)....

...The endosymbiont community was largely transmitted maternally as expected, however, hybrids carrying Arsenophonus were found significantly less often than expected, pointing either towards loss of this endosymbiont in viable hybrids or lower viability of hybrids carrying it....
