dc.description.abstractRandom deviations from the perfect symmetry of normally bilaterally symmetrical characters exist during individual development as a result of various environmental conditions. Fluctuating asymmetry (FA) is often used as a measurement of developmental instability, and within-environmental variation (CV(e)) is also considered as an indicator of developmental deviations. These two parameters may indicate the quality of the environmental habitat of organisms. For herbivore insects, such as aphids, any change in their host plants conditions is important and directly affects their development. The presented investigation revealed that both Lead (Pb) and Copper (Cu) accumulation in different host plants resulted in a significant amount of deviations from bilateral symmetry in cabbage aphid (Brevicoryne brassicae). Cabbage aphid populations showed higher FA and CV, on heavy metal accumulated cabbage and radish than on non-contaminated cabbage and radish plants. However, the pattern between developmental instability and fitness measurements was inconsistent. Thus, this study does not support the hypothesis that asymmetry is a valuable bioindicator of developmental instability. (c) 2005 Elsevier Ltd. All rights reserved.
