摘要：许多寄生虫能改变寄主的行为，增加寄主被捕食者猎取的风险，因此，促进了寄生虫生命周期下一轮回的起始。但是，法国Bourgogne大学专家和她的团队称：一种寄生虫却能保护寄主，使得捕食者厌恶其寄主。
Many parasites modify their host's behaviour, upping the host's risk of being ingested by a predator, and thus hastening the next stage of the parasites' life cycle. But, say Lucile Dianne and her colleagues at the University of Bourgogne in Dijon, France, one parasite can also do the opposite, making its victims predator-averse.
Pomphorhynchus laevis worms live in the amphipod Gammarus pulex (pictured) until they reach a stage at which they can infect the fishes that consume the amphipods. At this point, the amphipods grow increasingly reckless. But the researchers found that, in an experimental set-up, G. pulex infected with parasites that are at an earlier developmental stage spend more time hiding than uninfected individuals. This hiding behaviour protects the creature against fish predation, allowing time for the worm parasites to prepare for their next victim.
