“…Our results partly support this pattern, with evidence for genetic differentiation separating northern Asia ( COI data only, no microsatellite data available), SE Asia and Indonesia (both COI and microsatellite data). Within mainland SE Asia, our data revealed little to no population structure despite high genetic diversity and COI haplotype diversity, supporting the findings of other studies [59, 69, 70]. Using climatic modelling and two mitochondrial markers, Porretta, Mastrantonio [59] suggested that the low genetic structure across this mainland SE Asian region could be explained by the demographic growth between interconnected populations of Ae .…”

BackgroundWithin the last century, increases in human movement and globalization of trade have facilitated the establishment of several highly invasive mosquito species in new geographic locations with concurrent major environmental, economic and health consequences. The Asian tiger mosquito, Aedes albopictus, is an extremely invasive and aggressive daytime-biting mosquito that is a major public health threat throughout its expanding range.Methodology/Principal findingsWe used 13 nuclear microsatellite loci (on 911 individuals) and mitochondrial COI sequences to gain a better understanding of the historical and contemporary movements of Ae. albopictus in the Indo-Pacific region and to characterize its population structure. Approximate Bayesian computation (ABC) was employed to test competing historical routes of invasion of Ae. albopictus within the Southeast (SE) Asian/Australasian region. Our ABC results show that Ae. albopictus was most likely introduced to New Guinea via mainland Southeast Asia, before colonizing the Solomon Islands via either Papua New Guinea or SE Asia. The analysis also supported that the recent incursion into northern Australia’s Torres Strait Islands was seeded chiefly from Indonesia. For the first time documented in this invasive species, we provide evidence of a recently colonized population (the Torres Strait Islands) that has undergone rapid temporal changes in its genetic makeup, which could be the result of genetic drift or represent a secondary invasion from an unknown source.Conclusions/SignificanceThere appears to be high spatial genetic structure and high gene flow between some geographically distant populations. The species' genetic structure in the region tends to favour a dispersal pattern driven mostly by human movements. Importantly, this study provides a more widespread sampling distribution of the species’ native range, revealing more spatial population structure than previously shown. Additionally, we present the most probable invasion history of this species in the Australasian region using ABC analysis.

“…Despite the availability of mitogenomes, virtually all A. albopictus mitochondrial DNA (mtDNA) surveys were restricted to short segments of the cytochrome c oxidase subunit 1 (COI) and/or NADH dehydrogenase subunit 5 (ND5) genes, suggesting a limited phylogeographic differentiation among populations, possibly also caused by the inclusion in these studies of laboratory stocks or sibling eggs (Delatte et al, 2011; Kamgang et al, 2011, 2013; Porretta et al, 2012; Zhong et al, 2013; Zawani et al, 2014; Futami et al, 2015) and the postulated cytoplasmatic sweep caused by Wolbachia infection (Armbruster et al, 2003). However, more extensive sequencing of the COI gene has revealed more variation than previously thought (Goubert et al, 2016), a scenario also partially supported by microsatellite studies that highlighted slight genetic diversity between native and adventive populations with high variability within populations (Manni et al, 2015).…”

The Worldwide Spread of the Tiger Mosquito as Revealed by Mitogenome Haplogroup Diversity

et al. 2016

In the last 40 years, the Asian tiger mosquito Aedes albopictus, indigenous to East Asia, has colonized every continent except Antarctica. Its spread is a major public health concern, given that this species is a competent vector for numerous arboviruses, including those causing dengue, chikungunya, West Nile, and the recently emerged Zika fever. To acquire more information on the ancestral source(s) of adventive populations and the overall diffusion process from its native range, we analyzed the mitogenome variation of 27 individuals from representative populations of Asia, the Americas, and Europe. Phylogenetic analyses revealed five haplogroups in Asia, but population surveys appear to indicate that only three of these (A1a1, A1a2, and A1b) were involved in the recent worldwide spread. We also found out that a derived lineage (A1a1a1) within A1a1, which is now common in Italy, most likely arose in North America from an ancestral Japanese source. These different genetic sources now coexist in many of the recently colonized areas, thus probably creating novel genomic combinations which might be one of the causes of the apparently growing ability of A. albopictus to expand its geographical range.

“…Worldwide, extensive and repeated insect control activities have involved source reduction and insecticide application, leading to the reduction and/or eradication of A. albopictus populations [68][69] . As a result, reduced levels of genetic variation were observed in the current study.…”

“…Nevertheless, the main concern is that most of the genetic diversity found in the Asian tiger mosquito populations (51%) is through the use of mtDNA markers. In the last decade, the use of mtDNA has been widely used in population genetics studies for reconstructing historical patterns of population demography, admixture, biogeography and speciation in arthropods, included A. albopictus 47,69 . However, integration of mitochondrial sequences in nuclear DNA (referred to as NUMTs) has been discovered in many eukaryotes, including A. aegypti 53,[90][91][92][93] .…”

Introduction: Aedes (Stegomyia) albopictus (Skuse, 1894) is a vector for dengue and chikungunya viruses in the field, along with around 24 additional arboviruses under laboratory conditions. Knowledge of the genetic diversity of insect vectors is critical for the effective control and elimination of vector-borne diseases. Objective: We determined the current scenario of the genetic diversity in natural populations of A. albopictus through a systematic review. Methodology: It was possible to establish the first reports and distribution of A. albopictus populations in the world, as well as its genetic diversity, population genetic structure and molecular markers used to determine its genetic diversity. Results: A. albopictus is distributed worldwide with genetically structured populations and low diversity; however, 89.5% of the genetic diversity known is based on the use of RFLP, allozymes, isozymes, and mtDNA molecular markers that exhibit significant problems according to the literature. After the results were obtained, a critical analysis was carried out and existing shortcomings were detected. Conclusion: The current knowledge of genetic diversity of A. albopictus is based on genetic markers that exhibit significant problems reported in the literature; therefore, vector control programs targeting A. albopictus populations, may be compromised.
