By simulating test for effects of dipterex insecticide pollution on soil animals, a total of 679 soil animal individuals was collected, belonging to 1 phylums, 20 orders, and 1 suborder. The dominant groups were Prostigmata and Collembola, accounting for 54.93% of the total number of soil animals captured, and others were the ordinary groups and rare groups. The result showed that with the increase of dipterex concentration, the species and quantities of soil animal as well as the Shannon-Wiener diversity index and Pielou evenness index decreased, but the Simpson dominance index increased; And as the exposure time of dipterex increased (24 - 72 h), the species and quantities of soil animals decreased.
