摘要：

The effects of spring treatments of an insecticide, carbofuran, on the soil animal decomposer community of an Ontario [Canada] cornfield were assessed by measuring fluctuations in soil animal populations and changes in rates of leaf litter decomposition from bags of different mesh sizes. For several weeks after treatment, reductions in soil microfauna and reductions in the rate of corn leaf decomposition were observed, but, by autumn, the total number of soil microarthropods and litter decomposition rates were similar to those in untreated control plots. Earthworm populations seemed unaffected by in-row treatments of carbofuran, but broadcast treatments reduced worm populations significantly.
