“…Results indicated an overall differentiation of 0.599 (SE = 0.015), or a relatively high degree of genetic differentiation within the complex. Positive Darwinian selection was demonstrated for 99 of 141 COI sequences, each representing a single individual from worldwide collections (Brown and Idris 2005). The greatest number of haplotypes exhibiting positive selection were those in the major clade demarcating Asia I-Australia at 79%, compared to the second greatest for the major clade comprising Sub-Saharan Africa haplotypes, at 69%.…”

A number of divergence estimates point to Africa and/or a portion of Asia as likely geographical centers of population expansion and diversification (Berry et al 2004;Brown 2000;Brown and Idris 2005;Brown et al 2004a;Boykin et al 2007; De la Rua et al 2006;Moya et al 2001;Qui et al 2007;Sseruwagi et al 2005).…”

“…Evaluation of conserved and variable sites in the 780 base COI sequence reveals unusually high divergence at both the nucleotide and protein levels (Brown and Idris 2005). For example, alignment of the consensus amino acid sequence identified 26 polymorphic sites clustered at the C-terminus end of the protein.…”

“…Some studies have simply reported an association (Gray et al, 2002), while others have shown there is genetic control over the ability to transmit a virus, usually through crossings of competent and incompetent populations (Gray et al, 2007). Genetic control of vector competence has been demonstrated for T. tabaci (Cabrera-La Rosa and Kennedy, 2007), other thrips (Halaweh and Poehling, 2009), mosquito (Gray et al, 2007), planthopper (Zeigler and Morales, 1990), whitefly (Brown and Idris, 2005) and aphid (Burrows et al, 2006). Phylogenetic analysis of Australian T. tabaci populations based on COI sequence comparisons showed clustering corresponded to differences in vector competence and the host from which they were collected.…”

Genetic and host-associated differentiation within Thrips tabaci Lindeman (Thysanoptera: Thripidae) and its links to Tomato spotted wilt virus-vector competence GC Westmore, FS Poke, GR Allen and CR Wilson Of eight thelytokous populations of onion thrips (Thrips tabaci) collected from potato (three populations), onion (four) or Chrysanthemum (one) hosts from various regions of Australia, only those from potato were capable of transmitting Tomato spotted wilt virus (TSWV) in controlled transmission experiments. Genetic differentiation of seven of these eight populations, and nine others not tested for TSWV vector competence, was examined by comparison of the DNA sequences of mitochondrial cytochrome oxidase subunit 1 (COI) gene. All Australian populations of T. tabaci grouped within the European 'L2' clade of Brunner et al. (2004). Within this clade the seven populations from potato, the three from onion, and the four from other hosts (Chrysanthemum, Impatiens, lucerne, blackberry nightshade) clustered as three distinct sub-groupings characterised by source host. Geographical source of thrips populations had no influence on genetic diversity. These results link genetic differentiation of thelytokous T. tabaci to source host and to TSWV vector capacity for the first time.

Phylo‐biogeographical distribution of whitefly Bemisia tabaci (Insecta: Aleyrodidae) mitotypes in Ecuador

The Bemisia tabaci complex in Ecuador was studied with respect to phylogenetic relationships and eco-geographical distribution. Whitefly samples were collected from natural and agricultural environments in nine provinces of Ecuador (latitude, 2°N-5°S; longitude, 78°-81°W). Mitotypes were identified based on phylogenetic analysis of the 3 0-mtCOI-tRNAleu region (832 bp) and corrected pairwise distance analysis. The distribution of mitotypes was modeled using MaxEnt, and their predicted niches were characterized according to environmental gradients. Four B. tabaci mitotypes were identified, of which three are endemic, herein ECU1-3, and the other is the introduced B mitotype. Mitotypes ECU1 (44%), ECU2 (0.74%), and ECU3 (1.47%) grouped in the American Tropics (AMTROP) species and diverged by as much as 10%, which was higher than previous estimates for the AMTROP clade of 7-8.6%. Although haplotypes of ECU1 and ECU2 are known from the American Tropics, this is the first report of the ECU3 mitotype, which may possibly be restricted to southern Ecuador. The distribution of the three ECU-endemic mitotypes spanned the high-altitude niches of the western slope of the Andes, rich in microclimates with variable temperature and humidity conditions. The non-endemic B mitotype (47%) occurred only in the irrigated cropping systems located in hot and/or dry-tropical ecological niches. Of the endemic mitotypes, ECU1 occupied the most ecological niches. Among variables contributing to ECU1 and B mitotype niche range assignments, the most significant to influence ecological range was rainfall. The B. tabaci endemic to Ecuador were more diverse with respect to mtCOI-tRNAleu sequence than previously known, and occupied distinct microclimate niches suggestive of ecological resilience.
