Aphid Guard Aphid Banker Plant
This aphid banker plant consists of young barley infested with bird cherry oat aphids, an aphid species that attacks grasses, not broad leaved plants. This supports Aphidius colemani, an aphid parasite used against green peach aphids and melon aphids.
These banker aphids support reproduction of Aphidius ervi, an aphid parasite used against potato aphids and foxglove aphids.
These aphids keep Aphidius ervi raring to go so that they can detect foxglove and potato aphids as soon as they appear in your crop. It is important to get the Ervi parasites going early in the season, before the harmful aphids can intiate high numbers. In its third year of use, we supply pea aphids as the system for supporting Ervi. These aphids specialize on legumes, and do not harm broad leaved plants or grasses. Pea aphids are not compatible with lupine production.
