Role of kairomones in host location in the pennellid copepod parasite, Lernaeocera branchialis (L., 1767).
International audience The life cycle of the parasitic copepod Lernaeocera branchialis involves 2 hosts, typically a pleuronectiform host upon which development of larvae and mating of adults occurs and a subsequent gadoid host, upon which the adult female feeds and reproduces. Both the copepodid an...
