The whitefly, Benusia tabaci (Gennadius) (Hemiptera Aleyrodidae) is a cryptic species complex distributed worldwide In Pakistan, B. tabaci poses a serious threat to agriculture production To understand its diversity in Pakistan, a large-scale sampling was conducted from various locations of all four provinces of the country and Mitochondrial cytochrome oxidase I (mfCOI) gene sequencing was used to determine the whiteflies genetically. The study revealed the presence of five different cryptic species in Pakistan namely Asia II-l, Asia II-5, Asia II-7, Asia 11-8 and MEAM-1, respectively Among them, Asia II-l, which was previously reported from a few areas in the country, had been found now to be prevalent all over the country covering 88.7% of all the sequenced samples Based on the mfCOI sequences and genetic distance analyses, the diversity of Asia II-l was much greater than all other cryptic species, which exist only in small patches.
