An investigation was carried out for evaluating the table grape genotypes against incidence of thrips in Sector No. 70, UHS, Bagalkot, Karnataka after fore pruning (October) 2016. Results revealed that among 12 grape genotypes studied, significantly lowest thrips population was recorded in Red Globe (T12) during 29, 71 and 99 days after pruning (1.40, 4.08 and 3.28 thrips/shoot respectively). However, significantly highest population of thrips was recorded in Fantasy Seedless (T10) (4.08, 6.14 and 4.76 thrips/shoot) during 29, 71 and 99 DAP respectively. Correlation studies revealed that the incidence of thrips per shoot was significant and high positively correlated with sugar and amino acid. The incidence of thrips per shoot was significant and high negatively correlated with phenol and tannin. The incidence of thrips per shoot was positively correlated with leaf thickness.
