Common elder Sambucus nigra as banker plant to control pink apple aphid Dysaphis plantaginea using aphid-eating syrphids
Fruitteelt nieuws 16(4): 23-25
An elder hedge was planted around an apple orchard in Belgium to investigate its potential as host for colonies of Scaeva, Syrphus, Epistrophe and Episyrphus spp. These aphids are predators of pink apple aphids and black elder aphids (Aphis sambuci). The latter was released in 2002 to provide food for the syrphids. During the spring of 2002 Epistrophe larvae were found on aphid colonies in elder and apple trees.
