Pesticide-induced changes in surface migration by earthworms in grassland were investigated using trapping and the fungicide benomyl. Traps were tended daily for 15 days after spraying, resulting in 2152 earthworms, five species, and juvenile predominance which reflected species/life-stage composition in the soil. Significant increases in migration (all worms) occurred already by day 2 due to spraying, final treatment level being 2.8 x control. Life-stage composition indicated an increased… CONTINUE READING
