“…In molecular analysis based upon DNA sequence data, the internal transcribed spacer-1 and 2 (ITS-1 and ITS-2) regions of ribosomal DNA (rDNA) have been frequently used to evaluate phylogenetic relationships among species and varieties of insects (Honda et al, 1998;Marinucci et al, 1999;De Barro et al, 2000), to identify sibling species (Porter and Collins, 1991) or extremely fine species in size (Thomson et al, 2003), and also to analyze the genetic variation among different local populations of a given species (Slaney and Blair, 2000;Douglas and Haymer, 2001;Alvarez and Hoy, 2002).…”

Genetic variations of the internal transcribed spacer-1 region in sweet potato weevil, Cylas formicarius, were examined from 27 collection sites in the main infested areas in the world, except Africa, in this study. The ITS-1 lengths of 36 weevils tested in this study ranged from 557 to 587 bp, and were conspicuously longer in weevils from India. The genetic distances between weevils from India and from the other areas tested were larger than among weevils from the latter areas. The phylogenetic tree based on ITS-1 sequences consisted of two main clades of India and East Asia consisting of Northeast Asia and Southeast Asia subclades. The former subclade was also divided into three minor subclades. Weevils from Georgia and Hawaii (USA), and St. Kitts (the West Indies) belonged to the same subclade as those from Guangdong (China) and Hanoi (Vietnam). Also, weevils from the Ogasawara Islands (Japan) belonged to the same subclade. On the other hand, weevils from the Southwest Islands (Japan) belonged to the same subclade as those from Taiwan. When referring to human historical events, C. formicarius would have gradually spread in southern Asia due to its limited dispersal ability since originating in the Indian subcontinent 90 million years ago. However, after becoming associated with sweet potato, especially after the nineteenth century, local populations with fairly different genetic properties from Indian weevils would have been rapidly spread by human transportation of infested sweet potato throughout the world.

“…Mitochondrial COI sequencing for B. tabaci has been used to identify relationships for the B. tabaci complex (Frohlich et al, 1999;Boykin et al, 2007). The taxonomic status of B. tabaci has been problematic; however, genetic differentiation and behavioral differences among populations have led to a proliferation of alternative designations and biotypes (Perring, 2001;De Barro et al, 2000, 2005Boykin et al, 2007;Dinsdale et al, 2010), partly because authors have been constrained to treating the group as a single taxonomic species.…”

ABSTRACT. Bemisia tabaci (Hemiptera: Aleyrodidae) consists of a complex of morphologically indistinct biotypes that vary mainly in their capacity to transmit plant viruses and to induce physiological disorders in plants of economic importance. The adaptability of B. tabaci to many regions of the world has fostered the appearance of various biotypes and has resulted in a broad spectrum of host plants. Our goal was to identify which biotypes were present in four B. tabaci populations in Brazil. We quantified genetic variability between and within populations. Three individuals were collected from three host plant species: two populations on soybean (Campinas and Rondonópolis), one on pumpkin (Barreiras) and one on tomato (Cruz das Almas) in three States of Brazil (São Paulo, Mato Grosso, and Bahia). We chose one sequence of the B biotype, obtained from GenBank; the Campinas population, which had been previously characterized as biotype B, was used as a control for this biotype. We also included one sequence of the Q biotype, obtained from GenBank, as an outgroup. The COI region of the mtDNA gene was partially amplified with the CI-J-2195 and L2-N-3014 pair of primers, and the reaction products were sequenced. Based on distance- based algorithm analyses, we found that all haplotypes belong to biotype B, which was confirmed by the haplotype network. Genetic structure analyses showed that the host plant species does not influence population structuring of this pest; only the geographic location mattered.

“…MEAM1 (formerly known as biotype B), and MED (or biotype Q) are of particular importance: they are found highly polyphagous, resistant to a large number of insecticides. MEAM1 is believed to have originally merged from northeastern Africa, the Middle East, and the Arabian Peninsula, and the MED species comes from the Saharan and Sub-Saharan Africa; yet, both species have been found to be very invasive and are now worldwide distributed (De Barro et al 2000).…”

Tomato leaf curl New Delhi virus (ToLCNDV) originates from Asia where it is persistently transmitted by indigenous cryptic species of the whitefly Bemisia tabaci. The virus has recently invaded Spain, Tunisia, and Italy, and to investigate whether whitefly species new to the Mediterranean are involved, 35 populations were collected during 2015 from different crops in different regions of southern Spain. Comparison of partial mitochondrial cytochrome oxidase I sequences from the collected whiteflies revealed the existence of 7 different haplotypes belonging to the Mediterranean-Q1 cryptic species. ToLCNDV was detected in 15 populations collected from tomato, zucchini, and melon crops and from 5 different localities. The results suggest that MED-Q1 is also responsible for the current spread of ToLCNDV in Spain.
