Lead (Pb) is one of the hazardous heavy metals in which the studies of its long-term effect are limited to be done. The aim of this study was to observe the effect of lead on D. melanogaster's wing after being exposed with heavy metal in nine generations. The animal model used in this research was wild-type strain which was treated using three concentration levels of lead (i.e., 1000, 1500, and 2000 ppm). The flies used in the observation were eight imagoes (four male and four female) of the ninth generation. The flies were approximately one-day old chosen randomly from each treatment. The research results showed that the eight flies in each treatment-experienced wing changes in terms of form, size, and angle. Future research is encouraged to address the observation wing morphological changes in the next generations by eliminating lead treatment. This is necessary to observe the existence of plasticity phenomenon in the wing changes that occurred. © 2023 American Institute of Physics Inc.. All rights reserved.
