Abstract
A greenhouse trial investigated the uptake of cadmium and zinc by the bird-cherry oat aphid (Rhopalosiphum padi) feeding on wheat grown on s ewage sludge amended soil. The trial was conducted at application rate s of 0, 5, 7.5, 10, 15 and 20 tonnes ha(-1) dry solids. Concentrations of Cd and Zn were within current UK limits for potentially toxic elem ents in soils amended with sewage sludge. Cd and Zn in wheat plants we re significantly greater than controls. Batches of aphids feeding on t he wheat also showed a significant increase in the uptake of Cd and Zn . This study demonstrates a potential route of exposure to Cd and Zn f or the predators of cereal aphids. (C) 1997 Elsevier Science Ltd.
