Table 4 Cuticular hydrocarbons (CHCs) identified in the 10 most tolerant and 10 most sensitive strains. CHCs with a statistically significant different amount between the tolerant and sensitive strains are marked in bold. Linear retention index denotes the behavior of compounds on a gas chromatograph according to a uniform scale determined by the internal standard [84]. The data presented in this table is based on 10 tolerant and 10 sensitive strains and 7–10 replicates/strain (except for one strain with 4 replicates) (Additional file 13: Table S12)
