@DegenRolf @SteveStuWill Adaptive suicide in pea aphids: Pea aphids jump to their death to protect clone-mates when parasitized by parasitoid wasps, but only in xeric habitats when jumping would result in actual death: https://t.co/gz36L8hjNw
The pea aphid. “We believe this to be the first convincing evidence in support of the host suicide hypothesis." https://t.co/t6t2oRt2aP
“Here we report that pea aphid (Acyrthosiphon pisum) parasitized by the braconid wasp Aphidius ervi, exhibit apparent suicidal behaviour in response to both aphid alarm pheromone and approaching coccinellid (ladybird beetle) predators.” https://t.co/t6t2oR
“But the host will benefit from suicide, if by its death (and that of its parasite) the level of subsequent parasitism in its kin is reduced relative to that in non-kin.” https://t.co/t6t2oRt2aP
The host suicide hypothesis. “The fitness cost associated with suicide becomes negligible when infection by a parasitoid causes the expected reproduction of the host to approach zero." https://t.co/t6t2oRt2aP
“The host suicide hypothesis, which derives from inclusive fitness theory, postulates that parasitized individuals in spatially aggregated populations consisting of close kin may actively enhance their probability of dying.” https://t.co/t6t2oRt2aP
@katzider No luck with sauce... :( But here's another interesting case: http://t.co/WJMNNHjuB0
