EFFECTS OF HEAVY METAL ACCUMULATION IN HOST PLANTS TO CABBAGE APHID (Brevicoryne brassicae) - MORPHOLOGY

This study was carried out to search how heavy metal accumulation in host plants might affect expressions of aphid morphological traits. Accumulation of both copper (Cu) and lead (Pb) in the aphid host plants radish and cabbage, separately, had important effects on morphological traits of cabbage aphid, Brevicoryne brassicae L. population. All measured morphological traits of cabbage aphid become significantly smaller on host plants exposed to Cu and Pb. Results of the study clearly revealed the toxic effects of heavy metal accumulation on cabbage aphid and its subsequent adverse influences on aphid morphology.
