Esquivel et al. (2009) reported 6 species of <i>Euschistus</i> in Central Texas, and data presented here are a continuation of the previous study in an effort to better understand the seasonal dynamics of the 6 species. Pheromone-baited yellow pyramidal traps, lures, and insecticide-impregnated ear tags were used to collect adult brown stink bugs in pecan orchards adjacent to commercial fields of cotton, maize or soyabeans (<i>Glycine max</i>). From 26 May to 26 July 2010, individual nematodes were detected in each of 7 captured brown stink bug adults. The nematodes were infective 4th stage juveniles belonging to the family Mermithidae. All of the infected adults were collected from the same pecan orchard and cotton interface, constituting a 2.16% (n=324) infection rate for insects at this location. From the 3 traps along this interface, only 2 traps, separated by ~365 m, captured the infected adults. This is thought to be the first report of nematodes infecting brown stink bug adults. This report establishes a foundation for future research of mermithid nematodes as potential control agents of brown stink bug and other related hemipteran species that overwinter within orchard floors or other groundcover. 收起
