摘要

This study presents the first comprehensive survey of methyl eugenol (ME)-attracted Bactrocera spp. fruit flies across all 13 districts of Uttarakhand, India selected for its Himalayan biodiversity, diverse fruit production, and severe unquantified Bactrocera damage (20–60% losses), lacking prior multi-district ME-trap data (April–June 2024–2025). A total of 1919 males were captured using All India Coordinated Research Project on Fruits-standardized ME traps, comprising three key pests: B. dorsalis (Hendel) (1429; 74.46%), B. zonata (Saunders) (397; 20.68%) and B. correcta (Bezzi) (93; 4.84%). Diversity exhibited marked variation (Shannon-Wiener H′: 0.509–0.960; Simpson’s index D: 0.282–0.581), peaking in Rudraprayag (H′ = 0.960; highest richness) due to diverse orchards, while plains districts (Dehradun, Haridwar) showed the lowest values from urbanization and monoculture-based cropping systems. B. dorsalis dominated plains (> 90%), indicating invasion risks. These baselines enable district-specific IPM, prioritizing ME-based monitoring/suppression in high-diversity hills.
