Abstract

Tuberolachnus salignus and Pterocomma salicis are both aggregative aphids that have been noted within SRC crops. Experiments with willows grown in soil and in hydroponic culture reveal that T. salignus can reduce the above-ground yield of biomass willows, have severe negative effects on the roots and reduce the survival of both newly planted and established trees. Pterocomma salicis can also reduce yield and negatively affect the roots of host trees, but its effects are less marked. Both species can lead to plant stress and increase the vulnerability of host trees to other factors. Field observations indicate that T. salignus may be increasing in abundance in SRC crops.
