Abstract： [Objectives] To investigate the effects of exposure to lead on the morphological length and SOD, GST activity of Aleuroglyphus ovatus. [Methods] The morphological length, SOD and GST activity of different stages of A. ovatus were measured after exposure to different concentrations (0, 12.5, 25, 50 and 100 mg/kg) of Pb2+. [Results] In general, Pb inhibited the size of A. ovatus, but this first increased, then decreased, with increasing Pb2+ concentration. SOD and GST enzyme activity also first increased, then decreased, with increasing Pb2+ concentration, but overall the activities of these enzymes increased. [Conclusion] Pb2+ stress inhibited the size of A. ovatus and promoted SOD and GST activity. SOD and GST of activity in A. ovatus can be used to monitor heavy metal pollution in storage crops.
