Pest control in organic fruit orchards should not rely on external inputs with adverse effects but on other strategies and methods that support biodiversity and natural cycles adapted to local conditions.

Measures contributing to the enhancement of beneficial insects, pollinators and general biodiversity in the orchard can be integrated in the orchard or at the borders.

BIOFRUITNET Practice Abstract - The aphid Aphis gossypii is an efficient and common vector of the Citrus tristeza virus (CTV). To protect European citrus from CTV, aphid control is mandatory.

Beneficial insects and biopesticides are eco-friendly control approaches. Depending on the strategy, the synergy between them may result in effective aphid control.

The Woolly apple aphid (E. lanigerum) can cause severe damage, especially in organic cultivation; sucking activity causes bark growth, the so-called blood louse canker.

Promoting natural antagonists in organic orchards is a key element in controlling E. lanigerum. Further, the tree growth should be balanced through proper (root) pruning.
