Abstract

A scelionid wasp, Eumicrosoma beneficum Gahan, was reared from chinch bug, Blissus leucopterus leucopterus (Say), eggs collected from wheat (Triticum aestivum L.) near Odell, Nebraska, in June 1989. Three-hundred twenty-one of 680 chinch bug eggs (47.2%) were parasitized by E. beneficum. Based on a subsample of 92 wasps the population was 64.1% female. This is the first report of this wasp from Nebraska.
