The rosy apple aphid is one of the most important and dangerous pests. This is due to its short development cycle and large reproductive potential.
Solution
Promoting different antagonists through the establishment of flower strips is an important component of the rosy apple aphid control strategy in organic orchards.
Description
Flower strips have a positive impact on pest management – addressing various pests. They enhance the biodiversity of orchards and promote beneficial insects, such as Hoverfly, lacewing and ladybug larvae as well as birds and bats.
Practical recommendation
• Use native perennial and species rich flower strips to promote aphid predating and/or -parasitising beneficial insects (e.g., flower bugs, gall midges, etc.).
• Several adult parasitoids and predators depend on open flowers and accessible pollen for their development.
• Important native herbs with open flowers are Meadow-Labwort (Galium album), Yarrow (Achillea millefolium), Dyer’s Chamomile (Anthemis tinctoria), Chicory (Cichorium intybus), wild carrot (Daucus carota), Meadow Pippe (Crepis biennis), Rough Dandelion (Leontodon hispidus).
• Place flower strips in the middle of each or each second driving alley for best results. Alternatively place them along the edges of orchards as high perennial strips.
• Be cautious in vole management as voles may find shelter among flower strips.
