From Pest Surveillance to Precision Management: Emerging Technologies for Monitoring, Forecasting and Sustainable Management of Rice Stem Borers

P. J. Kabilan, K. Karthikeyan, Haseena Bhaskar, A. P. Padmakumari & K. C. Ayyoob · Journal of Scientific Research and Reports · 2026

Rice stem borers continue to be major pests in rice cultivation because their larval forms exhibit cryptic behaviour, asynchronous development and dependence on crop phenology, which undermine conventional scouting approaches. The yellow stem borer, Scirpophaga incertulas (Walker...

Gene Validation for Brown Plant Hopper Resistance in Rice Varieties Using SSR Markers

Arun Chacko, V. G. Jayalekshmy, K. Karthikeyan, Beena Thomas, S. Shanas & A. M. Shahiba · International Journal of Plant & Soil Science · 2023

The Brown Plant Hopper (BPH), Nilaparvata lugens (Homoptera: Delphacidae) is one of the most destructive insect pests causing significant yield loss in most of the rice cultivars of Asia. Marker-assisted backcrossing is used to introgress the genes for BPH resistance in which the...

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...
