Using the DG index to measure the diversity of soil invertebrate assemblages was more reasonable than Shannon-Wiener Diversity Index in this case because the Acarina predominated in the samples which covered up the information of other soil invertebrate taxa, while the DG index is proposed on base of the hypothesis that every species has equal independence and importance in the community and could be compared with inter-community.

The 9 common used insecticides of cypermethrin 4.5%EC, omethoate 40%EC, chlorpyrifos 40%EC, acetamiprid 3%EC, imidacloprid 10%EC provided excellent control for wheat aphids in fields. The control effects were over 90% at 7 days after spraying. The 9 insecticides had bad effects on aphidius and coccinellidae in three days after spraying and the number of two natural enemies decreased rapidly. But on the 7th day, the number of the two natural enemies increased and there were difference between those treated with imidacloprid, acetamiprid and abamectin and CK. BT had no evident difference compared to the control.

The results show that 60Co-γ ray radiation has the most remarkable effect on the degradation of organophosphorus pesticides such as fenitrothion, parathion, methyl-parathion, phorate and chlorpyrifos and the maximum degradation rates are over 85%. The degradation rates of methamidophos, acephate, malathion ,dimethoate are slightly inferior to them and the optimum degradation rates is just only 34.70%. At the same time, the contents of soluble total sugars, glucose, fructose, sucrose and total sugars in apple juice decrease unconspicuously, but the total acid content in apple juice and its color value and clarity increase. Based on a comprehensive consideration of the 60Co-γ radiation effect on the actual degradation of organophosphorus pesticides in apple juice and its main chemical and physical indexes, organophosphorous pesticides residue will be decreased to a lower level with radiation dose of about 5 kGy but the main chemical and physical indexes of export apple juice can not be affected.
