Aphidius colemani is an amazing parasitic wasp that stings it's aphid victim and lays its egg directely inside the aphid. In a couple of days, the aphid die and begin to swell up, and as it swells a new parasitic wasp is developed and will soon emerge. Once the new parasitic wasp emerges and is able to fly, it will sting more aphids, lay more eggs, and continue the cycle again.
Aphidius is a good searcher, and can locate new aphid colonies when aphid populations are low.

Aphidius is a small parasitic wasp, native to North America. About 100 eggs are laid in aphids which the larvae subseqently develop. At 77 degrees F, 10 days are required from egg to adult for Aphidius. At 70 degrees F, two weeks are required from development on the parisite. Up to 200-300 aphids are attacked be each female. Fertilized eggs develop into females, nonfertilized eggs develop into males. There are usually twice as many females as males.
Aphidius is shipped as parasitized aphid mummies from which adults will emerge, or as newly emerged adults. Apply 500 to 3,000 Aphidius per acre.
