Integrative screening of plant volatiles through transient receptor potential channel docking, olfactometry, and field validation in <scp> <i>Bemisia tabaci</i> </scp>
BACKGROUND: Bemisia tabaci is a globally damaging pest for which insecticide reliance and resistance demand eco-rational, mechanism-informed alternatives. This study aimed to build a multi-tier pipeline of (TRP) channel docking, Y-tube olfactometry, RNA interference (RNAi) functional validation, and field trapping to identify and mechanistically support plant volatile attractants for improved monitoring/management. RESULTS: (AI = 3.17, CV = 6.6%) and retained 128.5% efficacy by day 6. CONCLUSION: The convergence of docking affinity, lab attraction, RNAi-dependent behavioural suppression, and consistent field performance supports TRPA1/TRPM as key contributors to volatile-guided orientation and delivers validated attractants (notably thymol, β-caryophyllene, cuminaldehyde) for stronger, more reliable whitefly monitoring and semiochemical-based integrated pest management. © 2026 Society of Chemical Industry.
