Table 1 Data on the 36 samples used in the RNAseq study

From: Candidate genes for monitoring hydrogen peroxide resistance in the salmon louse, Lepeophtheirus salmonis

Group n Description
Ls A-2013 4 Laboratory strain, sensitive to all delousing chemicals. Collected in northern Norway in 2011. Sixth generation. Not exposed to delousing chemicals during cultivation of any generation
Ls V-2013 5 Field strain, resistant to azamethiphos, deltamethrin, emamectin benzoate and hydrogen peroxide. Collected in mid-Norway in 2013
Ls A-P0 3 Laboratory strain. 12th generation of Ls A (sensitive). Not exposed to delousing chemicals during cultivation of any generation
Ls V-P0 4 Laboratory strain. Sixth generation of Ls V (resistant). Not exposed to delousing chemicals during cultivation of any generation
Ls F2-S 8 Second generation after crossing of Ls A-P0 and Ls V-P0, affected by 600 ppm H2O2 for 30 min (sensitive). Three lice from family group 1 and five lice from family group 2
Ls F2-R 12 Second generation after crossing of Ls A-P0 and Ls V-P0, unaffected by 1800 ppm H2O2 for 30 min (resistant). Seven lice from family group 1 and five lice from family group 2
  1. Notes: All adult female lice. Family group 1: females from the sensitive Ls A strain were crossed with males from the H2O2-resistant Ls V strain in the P0 generation. Family group 2: males from the sensitive Ls A strain were crossed with females from the Ls V strain
