Stink bugs (Hemiptera: Pentatomidae), including Euschistus spp., Chinavia hilaris (Say), and Nezara viridula (L.), are economic pests in most fruit, grain, vegetable, and row crops in the United States. An insect-collecting device made from a 2.8-L clear plastic PET® jar loaded with a pheromone lure attractive to Euschistus spp. and seated atop a 1.22-m-tall yellow pyramid base has been used to effectively capture Euschistus spp., C. hilaris, and N. viridula in orchards and field crops. The 2.8-L clear plastic PET jar is no longer commercially available, but a 3.8-L clear plastic PET jar can be purchased. This study was conducted to compare stink bug capture of a pyramid trap with the 2.8-L insect-collecting device to that of a trap with a 3.8-L one. Euschistus servus (Say) was the predominant stink bug species captured (92.9%) in pheromone-baited yellow pyramid traps in peanuts, followed by Euschistus tristigmus (Say) (4.5%), Euschistus quadrator (Rolston) (2.3%), Euschistus ictericus (L.) (1%), C. hilaris (1%), and N. viridula (1%). Total trap capture for E. servus and E. tristigmus in pyramid traps in peanut was similar regardless of the size of the insect-collecting device on the traps. So, the new 3.8-L top can be substituted for the old 2.8-L top on pyramid traps to capture these stink bugs.
