  abstract = {{T}he hairworm ({N}ematomorpha) {P}aragordius tricuspidatus has the ability to alter the behaviour of its terrestrial insect host (the cricket {N}emobius sylvestris), making it jump into the water to reach its reproductive habitat. {B}ecause water is a limited and critical resource in the ecosystem, we predicted that hairworms should adaptively manipulate host behaviour to maximize parasite reproductive success. {O}ur results supported the hypothesis that the host manipulation strategy of hairworms consists of at least two distinct steps, first the induction of erratic behaviour and then suicidal behaviour per se. {H}airworms secured mating by starting to manipulate their host before being fully mature. {O}nce induced, the cricket's suicidal behaviour was maintained until the host found water but the fecundity of worms decreased over time. {A}s expected, the fecundity of worms was better in crickets with suicidal rather than erratic behaviour.},
