Abstract

The effect of synthetic aphid honeydew on the populations of soil dwelling organisms has been studied in a woodland and a grassland soil. Honeydew sugars were shown to produce different effects in the two soil types. In the woodland soil a 30% increase in fungal population resulted from the application of synthetic honeydew at a rate equivalent to that from a natural aphid population. Peaks of up to a three-fold increase in bacterial numbers also occurred. In the grassland soil no increase in microbial population was evident, but soil respiration was 74% greater in a treated plot than in an untreated plot the day following the sugar amendment. In neither soil were microarthropod populations influenced by the addition of synthetic honeydew.
