Résumé
Many trophically transmitted parasites with complex life cycles manipulate their intermediate host’s antipredatory defenses in ways facilitating their transmission to final host by predation. Some parasites also protect the intermediate host from predation when noninfective during its ontogeny. The acanthocephalan Pomphorynchus laevis, a fish intestinal helminth, infecting freshwater gammarid amphipods as intermediate hosts, is using such a strategy of protection- then-exposure to predation by the definitive host. The whole time-course of this sequence of behavioral switch is however not yet known, and only one antipredator behavior has been studied to date. Are provided in this data set: the day of death of the animals, infected or not, their refuge use scores and their inactivity rate.
