Do aphids biomagnify Cd and Zn as a defence against predation?
Conference: British Ecological Society Annual Meeting
Dates: 5-7 September 2005Abstract:
The results of a study on sewage sludge application to agricultural soil have led us to propose that recycling sewage sludge can affect the biological control of grain aphids. This, we suggest, is due to the biomagnification of trace metals in the aphid presenting potentially toxic concentrations to predators.
