Abstract: Several physiological and biochemical indexes of tomato leaves injured by Aculops lycopersici were measured. Compared with the normal leaves, the content of chlorophyll, soluble sugar of tomato leaves damaged by Aculops lycopersici decreased as the time p rolonging and the amount of mite increasing. Contents of soluble p rotein and free amino acid of the tomato leaves rose when they were injured by little mites in short time. And that, as the time prolonging and the amount of mite increasing both the contents increased. The content of free proline of treatment 20 amount per leaf and 60 amount per leaf increased rapidly respectively by 31.7887% and 82.0439% in six days compared with the normal leaves.
