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...

Genotyping and Identification of Candidate Genes for Resistance to Brown Planthopper Nilaparvata lugens (Stal) in Traditional Rice Varieties

Gopu Sushma, Madhu Subramanian, Mani Chellappan, Rose Mary Francies, Karthikeyan K & V Jhansi Lakshmi · Journal of Advances in Biology & Biotechnology · 2026

Rice (Oryza sativa L.) feeds more than half of the global population, but its production is severely threatened by the rice specific pest brown planthopper (Nilaparvata lugens Stål). Developing resistant rice varieties is the most cost effective control strategy, making the ident...
