Abstract:
Three species of thrips, namely Thrips parvispinus (Karny), Megalurothrips distalis (Karny) and Megalurothrips usitatus (Begnall) were recorded and identified from cowpea flowers at IGKV, Raipur during the study period Rabi 2020-2021 and 2021-2022. The invasive thrips, Thrips parvispinus (Karny) has been reported for the first time infesting cowpea (Vigna unguiculata) in IGKV, Raipur, Chhattisgarh. Population of thrips, Megalurothrips distalis (Karny), Megalurothrips usitatus (Begnall), Thrips parvispinus (Karny), initiated at the flowering stage with a mean population of (1.09, 1.05/5 flower) during 2^nd week January and reached the peak (7.05, 8.06/5 flower) during 1^st week February. Both nymphs and adults lacerate on flowers, flower buds and small pods. Probably, it may pose serious threat to other important crops also.
