The aim of this research was to identify thrips species in cowpea in Teresina, Piaui, Brazil. Thrips collections were made during October and November, 2005, in the experimental field of Cowpea in "Embrapa Meio-Norte" (area of 2.7 ha), located in an area of transition between "Caatinga" and "Pre-Amazon", in Teresina-PI (05 degrees 05' 21" S; 42 degrees 48' 07" W), 72 m altitude. The technique used was based on individual sampling of the plant through simple sacking, adapted from Waquil et al. (1986). During these collections, there were not many individual thrips, although in warmer periods of the year, they can reach a higher number and become a significant problem in Cowpea (Freire Filho et al., 2005). Even with the identification of this species in Cowpea, more studies are required for a better understanding of which species of thrips are occurring in Cowpea in Piaui. Identifying more specimens will help to improve the handling techniques of this insect in the culture.
