Описание The cosmopolitan whitefly species, Bemisia tabaci has always been regarded as pests to a large range of worldwide crops. They are capable of transmitting plant viruses of different groups. Well-studied B. tabaci populations that have been differentiated are referred to as races or biotypes. Some of the commonly reported biotypes are B, Q, M, B2, L, H, A, C, N, K, R, P, E, S, J and AN. An analysis of genetic diversity of whitefly across Pakistan was conducted. It was based upon phylogenetic analysis of DNA sequence of mitochondrial gene Cytochrom Oxidase I. All sequences of mtCOI genes of whitefly samples from eight different geographical areas (Arif wala, Multan, Lodhran, Shujaabad, Bahawalnagar, Kabir wala, Tiba Sultanpur and Khanewal) were grouped in B. tabaci (Asia II). Sequencing results showed that clones obtained in this study were less diverse as they had between 98.3% and 99.6% identity among themselves and between 98.7% and 100% identity with the reported sequences available... |
