The Brown plant Hopper (BPH) Nilaparvata lugens L. (Homoptera: Delphacidae) is one of the most destructive insect pests causing significant yield loss in most of the rice cultivars of India as well as Asia.it is a typical phloem feeder. Hence, present study was undertaken on DNA molecular characterization of BPH population using SSR markers that will give clear understanding of BPH diversity in Gangavathi region. Ten SSR markers were screened in the selected 25 BPHs and all ten markers were screened to assess the molecular diversity.Genotyping data of SSR markers were analyzed using Unweight pair group method with Arithmetic Mean (UPGMA) method using DARwin V6.0. This analysis clustered 25 BPH populations into three groups. Cluster-I had highest number of BPH possessing 21 BPH population. Cluster-II with three BPH and cluster-III had one solitary BPH population. This indicates that majority of the BPH populations are similar at Gangavathi whereas two biotypes are quite different.
