The thrips of Oklahoma are not well known. The present list includes only 59 species
and several of these are partially or doubtfully determined. In contrast, there are
about 200 species recorded from Illinois (Stannard, 1968). Many of these should also
occur in Oklahoma. I have found only 8 papers that deal primarily with thrips in Oklahoma
and 4 of these are concerned with the tobacco thrips and other species in peanuts.
Other papers list species in alfalfa, tallgrass prairie and forage grasses. The eastern
forested areas of the state are not represented in any of these publications.
