• Aim: This study investigates the genetic diversity and distribution of different species of whiteflies on 20 host plants vegetables (cucumber, summer squash, pumpkin, tomato, brinjal, okra), field crops (sunflower, lettuce, field bean, lobia), commercial crops (cotton, tobacco), ornamentals (chrysanthemum, bellflower, marigold), fruit crops (lemon), trees (mulberry, wild tamarind, ficus), and others (wild brinjal) in New Delhi. Methodology: Genetic diversity was assessed through mitochondrial cytochrome oxidase-l gene-based molecular markers. Results: Phylogenetic analysis revealed that whitefly Bemisia tabaci was the most prevalent pest species across the crops reported in this study. The other whitefly species, viz., Dialeurodes sp., Singhiella simplex, Aleuroclava sp., Tetraleurodes acaciae, Trialeurodes vaporarium, and Aleurodicus floccissimus weve reported as pests of different horticultural crops. Interpretation: Genetic diversity of S. tabaci revealed that the genetic groups Asia 11-1 and Asia II-7 were most prevalent, while Asia I was the minor one. Understanding the species composition and genetic diversity of whiteflies will help in devising appropriate control strategies.
