The whitefly, Bemisia 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 (mtCOI) gene sequencing was used to determine the whiteflies genetically. The study revealed the presence of five different cryptic species in Pakistan namely Asia II-1, Asia II-5, Asia II-7, Asia II-8 and MEAM-1, respectively. Among them, Asia II-1, 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 mtCOI sequences and genetic distance analyses, the diversity of Asia II-1 was much greater than all other cryptic species, which exist only in small patches.
烟粉虱，即烟粉虱（Gennadius）（半翅目：粉虱科），是一种分布于全球的隐存物种复合体。在巴基斯坦，烟粉虱对农业生产构成严重威胁。为了解其在巴基斯坦的多样性，我们从该国四个省份的不同地点进行了大规模采样，并使用线粒体细胞色素氧化酶I（mtCOI）基因测序对粉虱进行基因鉴定。研究表明，巴基斯坦存在五种不同的隐存物种，分别为亚洲II-1、亚洲II-5、亚洲II-7、亚洲II-8和中东-小亚细亚1型。其中，亚洲II-1此前仅在该国少数地区有报道，现在发现其在全国普遍存在，占所有测序样本的88.7%。基于mtCOI序列和遗传距离分析，亚洲II-1的多样性远高于所有其他仅在小范围内存在的隐存物种。
