Abstract

The diversity of parasitoid wasps (Hymenoptera: Braconidae) in South Dakota is largely unexamined despite these wasps providing innumerable important ecological and biological services and being an essential part of natural and agricultural ecosystems. A new species of Acrisis Foerster was reared and is described from the native prairie legume Glycyrrhiza lepidota (Nuttall) Pursh, a plant studied for its potential for conservation and remediation. A large insect guild of seed predators and their associated parasitoids and hyperparasitoids reported from G. lepidota provides a list of potential hosts associated with the new parasitoid species. The agriculturally significant legume soybean, Glycine max (L.) Merrill, similarly has a large guild of pests, predators, and parasitoids, including the significant pest, soybean aphid, Aphis glycines Matsumura. A survey of aphid parasitoids (Hymenoptera: Braconidae: Aphidiinae) demonstrated a surprising diversity of species not previously recorded in soybean fields.
