From: The chemical signatures underlying host plant discrimination by aphids

EPG profiles for MS and TP aphids on each plant species. (A) Overall acceptance profile with positive LD1 values indicating preference for, and negative values indicating rejection of plants. (B) Discrimination profile with positive values indicating greater acceptance by MS aphids and negative values greater acceptance by TP aphids. Red = MS aphid native host, blue = TP aphid native host. There were 2 clones per race, 5–11 replicates per clone and plant species. Mean ± SEM.
