Mitochondrial DNA Evidence for a Distinct New World Group of Bemisia tabaci (Gennadius)(Hemiptera:Aleyrodidae)Indigenous to Argentina and Bolivia, and Presence of the Old World B Biotype in Argentina.

<br/><br/> A study was undertaken to establish the diversity within the Bemisia tabaci (Gennadius)species complex in Argentina using the mitochondria cytochrome oxidase I gene (mt COI)as a molecular marker. For one haplotype, common to cotton in the Santiago Province, biotic characters were evaluated, and included host range and life history traits: fecundity, generation time, intrinsic rate of increase, longevity, and rate of reproduction. To investigate genetic diversity, B. tabaci were collected from representative geographical locations and host plants in six provinces of Argentina. Also, B. tabaci found colonizing tomato plants in nearby Bolivia, which exhibited viruslike symptoms, were included in the study. We report, for the first time, the presence of the introduced 'B' biotype in Argentina, and present evidence for indigenous or 'local' B. tabaci haplotypes in both Argentina (ARG)and Bolivia (BOL), which collectively formed a distinctive, South American phylogeographic grouping of New World B. tabaci. Two closely related ARG haplotypes, ARG2/3 from Salta and Tucamán, and ARG1 from Santiago, shared 98.7
