“…The normal flight ranges of A. albopictus are limited, and these mosquitoes have not been observed to fly in strong winds (Novak, 1992). However, a recent study by Delatte et al (2013) reported that the flight ranges of the species might increase when females fail to find a suitable site for oviposition or blood-meals, which is likely assisted by wind. Movement and migration of A. albopictus may also be assisted by human activities, such as through the transport of used and waste tires as well as from the movement of other water-holding containers (Novak, 1992).…”

ABSTRACT. The mosquito Aedes albopictus is indigenous to SoutheastAsian and is a vector for arbovirus diseases. Studies examining the population genetics structure of A. albopictus have been conducted worldwide; however, there are no documented reports on the population genetic structure of A. albopictus in Malaysia, particularly in Penang. We examined the population genetics of A. albopictus based on a 445-base pair segment of the mitochondrial DNA cytochrome oxidase 1 gene among 77 individuals from 9 localities representing 4 regions (Seberang Perai Utara, Seberang Perai Tengah, Northeast, and Southwest) of Penang. A total of 37 haplotypes were detected, including 28 unique haplotypes. The other 9 haplotypes were shared among various populations. These shared haplotypes reflect the weak population genetic structure of A. albopictus. The phylogenetic tree showed a low bootstrap value with no genetic structure, which was supported by minimum spanning network analysis. Analysis of mismatch distribution showed poor fit of equilibrium distribution. The genetic distance showed low genetic variation, while pairwise F ST values showed no significant difference between all regions in Penang except for some localities. High haplotype diversity and low nucleotide diversity was observed for cytochrome oxidase 1 mtDNA. We conclude that there is no population genetic structure of A. albopictus mosquitoes in the Penang area.

Aedes albopictus is a highly invasive disease vector with an expanding worldwide distribution. Genetic assays using low to medium resolution markers have found little evidence of spatial genetic structure even at broad geographic scales, suggesting frequent passive movement along human transportation networks. Here we analysed genetic structure of Ae. albopictus collected from 12 sample sites in Guangzhou, China, using thousands of genome-wide single nucleotide polymorphisms (SNPs). We found evidence for passive gene flow, with distance from shipping terminals being the strongest predictor of genetic distance among mosquitoes. As further evidence of passive dispersal, we found multiple pairs of full-siblings distributed between two sample sites 3.7 km apart. After accounting for geographical variability, we also found evidence for isolation by distance, previously undetectable in Ae. albopictus. These findings demonstrate how large SNP datasets and spatially-explicit hypothesis testing can be used to decipher processes at finer geographic scales than formerly possible. Our approach can be used to help predict new invasion pathways of Ae. albopictus and to refine strategies for vector control that involve the transformation or suppression of mosquito populations..

Designing strategies to prevent invasion and to control Ae. albopictus populations in invaded regions requires knowledge of how Ae. albopictus disperses. Studies comparing Ae. albopictus populations have found little evidence of genetic structure even between distant populations, suggesting that dispersal along human transportation networks is common. However, a more specific understanding of dispersal processes has been unavailable due to an absence of studies using high-resolution genetic markers. Here we present a study using high-resolution markers, which investigates genetic structure among 152 Ae. albopictus from Guangzhou, China. We found that human transportation networks, particularly shipping terminals, had an influence on genetic structure. We also found genetic distance was correlated with geographical distance, the first such observation in this species. This study demonstrates how high-resolution markers can be used to investigate ecological processes that may otherwise escape detection. We conclude that strategies for controlling Ae. albopictus will have to consider both passive reinvasion along human transportation networks and active reinvasion from neighbouring regions.

“…Although the previous studies provided important insights into the possible origin of the invasions, their results were sometimes contradictory [e.g., the case of Greece (Kamgang et al, 2011;Manni et al, 2017) or Brazil (Birungi & Munstermann, 2002;Kambhampati, Black, & Rai, 1991)]. However, determining the origin of the invasions unequivocally and/or at a high level of resolution would be valuable for a variety of public health interventions (Beebe et al, 2013;Delatte et al, 2013;Galtier, Nabholz, Glemin, & Hurst, 2009;Goubert, Minard, Vieira, & Boulesteix, 2016;Hurst & Jiggins, 2005;Manni et al, 2015;Medley, Jenkins, & Hoffman, 2015;Mousson et al, 2005;Porretta, Gargani, Bellini, Calvitti, & Urbanelli, 2006;Zhong et al, 2013). First, knowledge regarding the source of an introduction's origin(s) can provide information on the invasive population's likely mode of transportation (Goubert et al, 2016;Jackson et al, 2015;Powell & Tabachnick, 2013).…”

Aedes albopictus, the “Asian tiger mosquito,” is an aggressive biting mosquito native to Asia that has colonized all continents except Antarctica during the last ~30–40 years. The species is of great public health concern as it can transmit at least 26 arboviruses, including dengue, chikungunya, and Zika viruses. In this study, using double‐digest Restriction site‐Associated DNA (ddRAD) sequencing, we developed a panel of ~58,000 single nucleotide polymorphisms (SNPs) based on 20 worldwide Ae. albopictus populations representing both the invasive and the native range. We used this genomic‐based approach to study the genetic structure and the differentiation of Ae. albopictus populations and to understand origin(s) and dynamics of the recent invasions. Our analyses indicated the existence of two major genetically differentiated population clusters, each one including both native and invasive populations. The detection of additional genetic structure within each major cluster supports that these SNPs can detect differentiation at a global and local scale, while the similar levels of genomic diversity between native and invasive range populations support the scenario of multiple invasions or colonization by a large number of propagules. Finally, our results revealed the possible source(s) of the recent invasion in Americas, Europe, and Africa, a finding with important implications for vector‐control strategies.
