Parasitism of the Lesser Cornstalk Borer, Elasmopalpus lignosellus, in ‘Florunner’ and ‘Spanhoma’ Peanuts by Native Hymenopterous Species in Oklahoma.¹

Parasitism of the lesser cornstalk borer, Elasmopalpus lignosellus (Zeller), by hymenopterous species in Oklahoma was compared in ‘Florunner’ and ‘Spanhoma’ peanut varieties. Of the 5 parasite species identified, the greatest incidence of parasitism in both varieties was by Invreia sp. There were no consistent differences in parasitic activity in Invreia sp. or other species related to peanut varieties from which E. lignosellus were collected.
