Sixteen plant bug species were collected across Oklahoma in field surveys conducted between June 12 and July 25, 2000. Species abundance and density varied by production region. Northern Oklahoma was the most diverse region recording 9 different species with the highest total catch followed by Southwest and West Central regions of Oklahoma respectively. Lygus lineolaris (Palisot) was the most abundant species caught followed by Spanagonicus albofasciatus (Reuter) and Pseudatomoscelis seriatus (Reuter). None of the species caught posed an economic threat to cotton during the sampling period. Alfalfa accounted for 38.8 % of the total number of plant bugs captured followed by cotton with 19.5 %. Lygus lineolaris (Palisot) was present in all three, production regions surveyed and poses the greatest threat where cotton is grown in close proximity to alfalfa.
