Zusammenfassung: | Abstract Bemisia tabaci is a species complex that causes damage to its broad range of plant hosts through serious feeding. It transmits plant viruses of different groups to important agricultural crops. Some important cash crops of Pakistan are sugar cane, rice, tobacco and seed oil. It shows high genetic variability and is differentiated as races or biotypes. Biotypes are, biotype Q, biotype B, biotype B2, biotype M, biotype L, biotype A, biotype H, biotype C, biotype K, biotype N, biotype R, biotype E, biotype P, biotype J, biotype S, biotype AN. Although the current report based on the Bayesian study of mitochondrial cytohrome oxidase gene1 (CO1) DNA sequences has classified the different populations of whiteflies into twelve genetic groups which are Mediterranean, Sub-Saharan Africa silverleafing, Indian Ocean, Asia II, Asia I, Australia, New World, Italy, China, Sub-Saharan Africa non-silverleafing, Mediterranean/Asia Minor/Africa and Uganda sweet potato. Begomoviruses is largest group of viruses transmitted by B. tabaci and cause major diseases of crops such as tomato and chili leaf curl disease, cassava mosaic disease; yellow mosaic disease of legumes and cotton leaf curl disease. The main objective of current study is to inculpate knowledge regarding genetic diversity of whitefly in cotton fields across Pakistan via analysis of partial DNA sequence of mitochondrial gene Cytochrom Oxidase I (mtCO1).
Resumo Bemisia tabaci é um complexo de espécies que causa danos a uma ampla gama de hospedeiros vegetais por meio de alimentação séria. Ele transmite vírus de plantas de diferentes grupos para importantes safras agrícolas. Algumas safras comerciais importantes do Paquistão são cana-de-açúcar, arroz, tabaco e óleo de semente. Apresenta alta variabilidade genética e é diferenciado em raças ou biótipos. Os biótipos são: biótipo Q, biótipo B, biótipo B2, biótipo M, biótipo L, biótipo A, biótipo H, biótipo C, biótipo K, biótipo N, biótipo R, biótipo E, biótipo P, biótipo J, biótipo S, biótipo AN . Embora o relatório atual baseado no estudo bayesiano das sequências de DNA do gene 1 da oxidase do citocromo mitocondrial (CO1) tenha classificado as diferentes populações de moscas-brancas em doze grupos genéticos, que são Mediterrâneo, África Subsaariana com folha de prata, Oceano Índico, Ásia II, Ásia I, Austrália, Novo Mundo, Itália, China, África Subsaariana sem folha prateada, Batata-doce Mediterrâneo / Ásia Menor / África e Uganda. Os begomovírus são o maior |
