Parasitoids reared from polistes (hymenoptera: Vespidae: Polistinae) nests in missouri, with a state record of elasmus polistis burks hymenoptera: Elasmidae

In Missouri, 177 specimens of the ectoparasitoid Elasmus polistis Burks (Hymenoptera: Elasmidae) were reared from nests of two paper wasp species: Polistes exclamans Viereck and Polistes metricus Say (Vespidae). This represents the first record of E. polistis in the state. Herein, we also report the coincidental emergence of 87 individuals of the polyphagous parasitoid Dibrachys cavus (Walker) (Hymenoptera: Pteromalidae) and E. polistis from the same P. metricus nest. Other parasitoids reared from Polistes nests are also reported, including Pachysomoides fulvus (Cresson) (Hymenoptera: Ichneumonidae), and Chalcoela iphitalis Walker (Lepidoptera: Pyralidae).
