Disruption of host‐seeking behaviour by the salmon louse, Lepeophtheirus salmonis, using botanically derived repellents
Abstract The potential for developing botanically derived natural products as novel feed‐through repellents for disrupting settlement of the salmon louse , Lepeophtheirus salmonis (Caligidae) upon farmed Atlantic salmon, Salmo salar , was investigated using an established laboratory vertical Y‐tube...
