Figure 1From: Salmon lice (Lepeophtheirus salmonis) showing varying emamectin benzoate susceptibilities differ in neuronal acetylcholine receptor and GABA-gated chloride channel mRNA expressionSusceptibility of salmon louse laboratory strains to emamectin benzoate (EMB). Toxicity responses of adult male salmon lice (Lepeophtheirus salmonis) laboratory strains S and PT in 24Ā hours immotility bioassays. Symbols represent the immotility response observed in one of duplicate beakers of ten individuals included for each combination of strain and treatment. Doseāresponse relationships (solid lines) were established using probit analysis, and yielded EC50 values of 73.9Ā Ī¼gĀ L-1 (95% confidence intervals: 58.9 - 92.0Ā Ī¼gĀ L-1) for the S strain and 642.3Ā Ī¼gĀ L-1 (642.3 - 957.4Ā Ī¼gĀ L-1) for the PT strain.Back to article page
