“…Inside of the Aedes genus, Ae. fluviatilis is the earliest branch split around 94 MYA (HPD95%:74.02-121.02), in contrast to other study that positioned it within other Aedes branches 84 . In summary, the Aedes genus is a paraphyletic group showing several phylogenetic incongruences even among studies that used different markers and species representatives.…”

Mosquitoes are insects of medical importance due their role as vectors of different pathogens to humans and other mammals. There is a lack of information about the evolutionary history and phylogenetic positioning of the majority of mosquitoes species. Here we sequenced the mitogenomes of mosquitoes species through low-coverage sequencing and data mining. A total of 37 draft mitogenomes were assembled representing 11 genera and 16 of those were sequenced for the first time. The recovered mitogenomes showed a coverage breadth average of 81.24%. Most of the species were clustered in monophyletic clades with other members of their own genus with exception of the Aedini tribe which was paraphyletic corroborating other findings. We established for the first time the monophyletic status of eight species from the tribe Mansoniini including both Coquillettidia and Mansonia genus and established the basal positioning of Aedeomyiini and Uranotaeniini tribes regarding the Culicinae subfamily. Molecular clock dated the Culicidae family emergence around 273 MYA and the split between Anophelinae and Culicinae subfamily around 182 MYA in the Jurassic period. Low-coverage sequencing is effective to recover mitogenomes, establish phylogenetic knowledge generating basic fundamental information to the understanding of the role of these species as pathogen vectors.

“…Our analyses produced three main findings in each of the three phylogenetic methods utilized: (1) Sequences associated with a particular species were generally found to cluster together; (2) Aedes and Ochlerotatus are not reciprocally monophyletic; and (3) Despite the lack of strict monophyly, our post hoc analyses support the existence of non-random associations among Aedes and Ochlerotatus “congeners” in our dataset. The latter finding suggests that some “ Ochlerotatus” species may form a valid evolutionary unit, although we find insufficient evidence to support its retention as a genus, which echoes conclusions made by Wilkerson et al (2015) and Soghigian et al (2017) based on phenotypic and molecular data, respectively.…”

“…Subsequent to commencing our study, we became aware of a related investigation by Soghigian et al (2017). Soghigian et al (2017) were particularly interested in the spread of invasive Aedes mosquitoes, and attempted to reconstruct the evolution of habitat specialization within the larger group (Aedini). Accordingly, they did not set out to resolve the separation of Aedes from Ochlerotatus , both of which were treated as Aedes subgenera, but their findings are relevant to our overall conclusions.…”

14Traditionally, entomologists have used morphological characteristics for mosquito taxonomy 15 and systematics. However, this approach does not take into consideration the genetic 16 relatedness of species. In 2000, the Aedes genus of mosquitoes in the tribe Aedini was split into 17 two genera (Aedes and Ochlerotatus), thereby elevating Ochlerotatus from subgenus to genus 18 rank, strictly based on morphology of adults. Herein, we use the genetic barcoding marker COI 19 to generate a phylogeny of 65 species of Aedes, Ochlerotatus, and Anopheles outgroup from 20 almost 900 sequences downloaded from BOLD systems. Our results reveal evidence of non-21 random, but polyphyletic clustering of Aedes and Ochlerotatus species, with a monophyletic 22 outgroup. We do find support for the validity of Ochlerotatus as an evolutionary unit, although 23 we find insufficient evidence to support its retention as a genus. We suggest that mosquito 24 phylogenetic analyses incorporate a greater number of genetic markers to help clarify our 25 understanding of Aedini species classifications, but caution that recent assessments based 26 solely on morphology may be insufficient. 27 28 45 Ochlerotatus (Meigen 1818, as cited in Harbach 2016). Through a series of morphology-46 informed phylogenetic studies, Reinert et al. 47 Ochlerotatus to genus status. This decision was based on the analysis of morphological 48 characteristics of 119 Aedini species across all life stages. The resulting morphology-based 49 phylogeny proposed this change to the previous classification that was based solely on adult 50 4 mosquito morphology. These revisions to the genera created instant controversy among 51 researchers and led to many journals that focus on these medically important species to 52 suggest caution with adopting the new designations (Reisen 2016). Because many species 53 within the genus Aedes are of significant medical importance (e.g., Aedes aegypti), 54 redesignation of any species would pose challenges for public health officials in relation to 55 using long standing species names when communicating with the public. In addition, as it has 56 been nearly two decades since Reinert first proposed elevating Ochlerotatus to a genus (Reinert 57 2000), and using a molecular approach to resolving the phylogenetic relationships among these 58 species is long overdue. Indeed, in an editorial about Aedini mosquitoes, Reisen (2016) noted: 59 "As more mosquito sequencing data become available … genetic analyses should be done to 60 confirm these phenotypic groupings." 61 DNA barcoding has been promoted as a universal tool for reliable species identifications 62 (Hebert et al. 2003, Hebert et al. 2004), and also as a tool for helping to resolve phylogenetic 63 relationships among species (Hajibabaei et al. 2007, Erpenbeck et al. 2007). The 648 base-pair 64 mitochondrial cytochrome c oxidase 1 gene (COI) is regarded as the standardized barcode gene 65 for species identification (iBOL 2018). Thus far, there is a mixed record of success of using COI...

However, these mosquitoes have adapted to using containers, tires, and plant pots as breeding grounds and are now found in urban, rural, and forested areas [4][5][6]. This adaptation is believed to be the reason behind the international spread of Aedes spp.…”

Land use boundaries represent human-physical interfaces where risk of vector-borne disease transmission is elevated. Land development practices, coupled with rural and urban land fragmentation, increases the likelihood that immunologically naïve humans will encounter infectious vectors at land use interfaces. This research consolidated land use classes from the GLC-SHARE dataset; calculated landscape metrics in linear (edge) density, proportion abundance, and patch density; and derived the incidence rate ratios of the Zika virus occurrence in Colombia, South America during 2016. Negative binomial regression was used to evaluate vector-borne disease occurrence counts in relation to Population Density, Average Elevation, Per Capita Gross Domestic Product, and each of three landscape metrics. Each kilometer of border length per square kilometer of area increase in the linear density of the Cropland and Grassland classes is associated with an increase in Zika virus risk. These spatial associations inform a risk reduction approach to rural and urban morphology and land development that emphasizes simple and compact land use geometry that decreases habitat availability for mosquito vectors of Zika virus.
