Thrips diversity of cotton ecosystem and the role of parthenium pollen grains in the transmission of tobacco streak virus (TSV) infection in cotton.

ABSTRACT: Survey in the cotton fields of Coimbatore and Erode districts confirmed the presence of three different thrips species including, Scirtothrips dorsalis, Scirtothrips oligochaetus, and Frankliniella occidentalis. Their identity was confirmed through morphometric analysis and molecular characterization. Tobacco streak virus (TSV) was detected in the leaves and pollen grains of both parthenium and cotton plants collected from infected cotton fields. The presence of TSV was confirmed through immuno-detection by direct antigen coating enzyme-linked immuno sorbent assay (DAC-ELISA). Further confirmation was accomplished by reverse transcriptase polymerase chain reaction (RT-PCR) using TSV coat protein-specific primers. Other than parthenium, weed plants in the cotton field s
