The main objective of the Functional Agro-Biodiversity project in the 'Hoeksche Waard' is the creation of favourable conditions both at the farm and landscape level for promoting bio-diversity and the role of natural enemies of pests.
Aphids constitute one of the major crop pests in Dutch arable and vegetable farming. The common syrphid, Episyrphus balteatus, is one of the important predators of this polyphagous pest complex. Since only its predatory larval stage subsists on aphids, while the adult live primarily on nectar and pollen, agro-biodiversity enhancement in the form of field margin plants can be particularly essential for syrphid survival and reproduction and for sustaining a viable natural enemy population. Field and laboratory investigations show that selected plant species strongly differ in their suitability as food sources for the syrphid E. balteatus, even within specific families. Aphid honeydew is an important supplementary food source. E. balteatus can, on the basis of our analyses, be regarded as an effective predator of aphids.
