More than 200 soil-surface and in-ground termite-monitoring devices were established across Oklahoma to collect termites. Termites were also collected from tree stumps and wooden buildings. Four species of Reticulitermes (Isoptera: Rhinotermitidae), R. flavipes, R. virginicus, R. tibialis, and R. hageni were recovered. From previous records, Gnathamitermes tubiformans (Buckley) is also indigenous to Oklahoma. Based on previous records, non-subterranean species including the dampwood termites Zootermopsis angusticollis (Hagen) and Zootermopsis nevadensis (Hagen), and the drywood termites Cryptotermes brevis (Walker) and Incisitermes minor (Hagen), are occasionally reported in lumber and furniture shipped to Oklahoma from California and Oregon, or from Gulf coast states. Known distributions of R. virginicus and G. tubiformans are extended. Reproductive flights of subterranean termites in Oklahoma peak from mid-March to mid-May. Observations of relative foraging densities across the state are also reported.
