%X We measured in a comet assay the damage of DNA in the hemocytes of various stages of the grasshopper Schistocerca gregaria after ex-posing them to various doses of Cd and Pb in the food. The mechanisms of Cd and Pb toxicity for grasshopper are discussed. The accumula-tion of heavy metals and stage of the insect may play important roles in causing the DNA damage. S. gregaria may be considered a valuable bio-indicator for evaluation the genotoxicity of en-vironmental pollutants.
