Aphid Banker Plant System helps establish predators and parasitoids in greenhouses. This technique involves raising the bird cherry oat aphids (Rhopalosiphum padi) on organic barley plants and placing them directly in the production. Aphid Banker Plant System is mostly used to conserve the parasitoid wasp populations Aphidius colemani and the predatory Aphid midge (Aphidoletes aphidimyza) .
Banker plant are used as a preventive IPM tool and they should be introduce into greenhouses as soon as you start your crops. Then we introduce the aphid midges Aphidoletes aphidimyza or of the parasitoid Aphidius colemani who will colonize these plants. This technique makes it possible to have a large predator population from the beginning of the season.
These aphids are only establishing themselves on monocotyledonous plants. Most spring bedding plants and vegetables such as greenhouse-grown tomatoes, cucumbers and sweet pepper are appropriate for this system.
For the commercial market only.
