Abstract

Survey was conducted in Watermelon bud necrosis virus (WBNV) hotspot regions in Tamil Nadu and Karnataka to identify the associated and predominant thrips species. The mean population of thrips ranged from 0.35 to 1.64/shoot and mean WBNV incidence ranged from 25 to 56% in different regions. A phylogenetic relationship of thrips sample collected from 29 locations of WBNV hotspot regions showed that Thrips palmi Karny was the predominant species and the DNA sequence analysis matched with more than 99% similarity.
