A comprehensive framework for the delimitation of species within the Bemisia tabaci cryptic complex, a global pest ‐species group

The performance of molecular phylogenetic trees derived from complete mitogenomes, single-copy nuclear genes, genome-represented single nucleotide polymorphisms, geographical range, and host plants was assessed in the classification ofBemisia tabaci species, as determined by reproductive compatibility datasets. Ultimately, a model is proposed for comprehending and disentangling the cryptic species complexes, drawing upon evidence from this investigation and previously published literature. AbstractIdentifying cryptic species poses a substantial challenge to both biologists and naturalists due to morphological similarities.Bemisia tabaci is a cryptic species complex containing more than 44 putative species; several of which are currently among the world's most destructive crop pests. Interpreting and delimiting the evolution of this species complex has proved problematic. To develop a comprehensive framework for species delimitation and identification, we evaluated the performance of distinct data sources both individually and in combination among numerous samples of theB. tabaci species complex acquired worldwide. Distinct datasets include full mitogenomes, single-copy nuclear genes, restriction site-associated DNA sequencing, geographic range, host speciation, and reproductive compatibility datasets. Phylogenetically, our well-supported topologies generated from three  dense molecular markers highlighted the evolutionary divergence of species of theB. tabaci complex and sug...
