Aphid Parasite Aphidius colemani

The Aphid Parasites or Aphidius colemani is a small parasitic wasp, native to North America. The parasitic wasp finds aphid colonies from a long distance by "alarm signals" produced by an infected plant. At shorter distance it smells the honeydew. The adult Aphidius feeds on honeydew.

Preferred food: Honeydew, the sticky fluid produced by aphid infestations.

Types of Aphids Controlled: Green Peach Aphid and other related aphids.

Shipment, and Biology: Aphidius are shipped as parasitized aphid mummies from which adults will emerge. This parasite can be used year-round in greenhouses and outdoors as it is not affected by short-day lengths.

Release rates: 500-3,000/acre, 2-3 times, one week apart, depending on the extent of infestation.
