Distinct Resistance Groups in Rice Germplasm from Kerala Based on Antibiosis and Tolerance Traits to Brown Planthopper, Nilaparvata lugens (Stal)

I. M. Swathy, M. S. Smitha, Mani Chellappan, K. Karthikeyan, Deepu Mathew & Rose Mary Francies · Journal of Advances in Biology & Biotechnology · 2026

Background: Brown planthopper (Nilaparvata lugens) is a major insect pest of rice that causes severe yield losses through direct feeding and hopperburn. The emergence of virulent populations and increasing concerns over insecticide resistance necessitate the identification of ric...
