Aphidius colemani is a parasitic wasp native to North America useful for biological control of aphids in greenhouses and outdoor growing. These tiny (1/8″ or 2-3 mm) aphid parasites seek out aphid colonies to provide food and a place to oviposit. Adult A. colemani respond to alarm signals from plants to locate the aphids where they feed on the honeydew aphids excrete. Parasitization occurs when females lay their eggs inside aphid nymphs. A. colemani eggs hatch into larvae which feed on the nymphs from the inside, the nymph swells and hardens into a leathery, grey or brown colored mummy. Once larvae mature, adult A. colemani wasps chew their way out of the aphid mummy and emerge to seek out aphids. These parasites are a good choice for year-round use (in greenhouses and outdoors) as the short days of winter do not affect them.

Adult parasitic wasps emerge from the mummies and females lay their eggs into aphids. The next generation of parasitic wasps develops inside the aphid, which converts into a leathery mummy. The adult parasitic wasp emerges through a hole at the rear of the mummy. The first mummies are noticed in the crop around 10-14 days after the first introduction.

Parasitized aphids turn into a brown mummy.
