For herbivore species such as aphids, different host plants may act as stressful environmental factors. Therefore, we studied the different host plant effects on symmetrical expression of morphological characters of cabbage aphid, Brevicoryne brassicae Linnaeus. Individuals were maintained on Brassica oleracea Linnaeus (Cabbage) for a long time and then transferred to Raphanus sativus Linnaeus (Radish). For all measured characters, cabbage aphids showed higher fluctuating asymmetry (FA) on radish which is a novel host for cabbage reared aphids although the two host plants belong to the same family. In contrast to FA, within-environmental variation (CV) for all measured characters were higher on cabbage. There was no consistent pattern between host plant effect and developmental noise indicators.eninfo:eu-repo/semantics/openAccessBiyolojiArticle63152238013
