Aphelinus abdominalis, parasitoid against aphids
A female Aphelinus abdominalis is 2.5-3 mm tall, has a black thorax, a yellow abdomen, short legs and short antennae. Males are slightly smaller and the back is darker in color. An aphid that is parasitized by this parasitoid wasp swells, becomes elongated in shape and turns black (mummy). A full grown adult hatches from the mummy through an irregularly torn hole on the back of the mummy.
Mode of Action:
Larger aphids are parasitized whereas smaller aphids are preyed upon and emptied (host-feeding). Hyperparasitization (where the parasite is re-parasitized) occurs less frequently than in Aphidius species.
For the control of potato aphid (Macrosiphum euphorbiae) and foxglove aphid (Aulacorthum solani) in greenhouse cultures and indoor plantings. However, other aphids can also be parasitized. Keep in mind repeated introductions. The product is sensitive to various chemical plant protection products. Ask advice for introduction strategy.
