As a biological control
Several small parasitic wasps are commercially available, primarily for control of aphids in greenhouses or interiorscapes. Some are generalists, other more specific as to the aphids they will attack. Among the most commonly available (and their hosts) are Aphelinus abdominalis (green peach aphid), Aphidius colemani (melon/cotton aphid, green peach aphid), Aphidius ervi (potato aphid, pea aphid, green peach aphid), and Aphidius matricariae (green peach aphid).
