This type of interaction is obviously restricted to ectoparasites or to the free stadium of endoparasites. Although UVR is generally associated with negative effects, it may also play a positive role on species interactions. Thus, for example, the ectoparasite copepod Lepeophtheirus salmonis (salmon lice) uses photoreceptors to avoid UVR and eventually to optimise host finding (e.g., by utilizing UV contrast vision [74]). 

Azamethiphos has a sufficiently low fish toxicity to be used against parasitic crustaceans (salmon lice) in fish breeding, whereas phoxim is used a lot in public health.

Semiochemicals associated with host and mate interaction have also been studied in the salmon louse L. salmonis and a host location molecule, isophorone, which activated adult male L. salmonis has been characterised (Ingvarsdottir et al. 2002). As a result, the authors proposed a slow release system for field trapping of lice. Moredue and Birkett (2009) reviewed the...
