Results of simulating experiments on methamidophos pesticide to soil animals showed that the methamidophos pesticide has an obvious effect on soil animals,the species and the amount of soil animals decrease obviously with increasing of methamidophos pesticide treating concentration;the diversity indexs are 3.7596,5.7962 and 8 5714 for 0 54ml/L,0.01ml/L and control of methamidophos pesticide treating concentration respectively.Toxicity test of earthworm showed that the methamidophos pesticide influences ob...
