“…Since the two species are distributed over a wide area in Korea and Japan and share a common habitat [ 34 , 46 , 47 ], research on their overlapping distribution is gradually increasing. Furthermore, there is a possibility of interspecific crossing [ 48 – 50 ]. Not only do the distributions overlap, but the two morphologies are also similar [ 34 , 40 , 51 ], and Japanese studies have shown that the two are phylogenetically close to each other [ 52 , 53 ].…”

Background Aedes mosquitoes are important invasive species contributing to the spread of chikungunya, dengue fever, yellow fever, zika virus, and other dangerous vector-borne diseases. Aedes albopictus is native to southeast Asia, with rapid expansion due to human activity, showing a wide distribution in the Korean peninsula. Aedes flavopictus is considered to be native to East Asia, with a broad distribution in the region, including the Korean peninsula. A better understanding of the genetic diversity of these species is critical for establishing strategies for disease prevention and vector control. Methods We obtained DNA from 148 specimens of Ae. albopictus and 166 specimens of Ae. flavopictus in Korea, and amplified two mitochondrial genes (COI and ND5) to compare the genetic diversity and structure of the two species. Results We obtained a 658-bp sequence of COI and a 423-bp sequence of ND5 from both mosquito species. We found low diversity and a nonsignificant population genetic structure in Ae. albopictus, and high diversity and a nonsignificant structure in Ae. flavopictus for these two mitochondrial genes. Aedes albopictus had fewer haplotypes with respect to the number of individuals, and a slight mismatch distribution was confirmed. By contrast, Ae. flavopictus had a large number of haplotypes compared with the number of individuals, and a large unimodal-type mismatch distribution was confirmed. Although the genetic structure of both species was nonsignificant, Ae. flavopictus exhibited higher genetic diversity than Ae. albopictus. Conclusions Aedes albopictus appears to be an introduced species, whereas Ae. flavopictus is endemic to the Korean peninsula, and the difference in genetic diversity between the two species is related to their adaptability and introduction history. Further studies on the genetic structure and diversity of these mosquitos will provide useful data for vector control.

“…Aedes japonicus (Theobald) (Diptera: Culicidae), Aedes koreicus (Edwards) (Diptera: Culicidae), and Aedes flavopictus (Yamada) (Theobald) (Diptera: Culicidae) are just three invasive mosquito species that have been identified as possible incursion risks within temperate regions of the world that may bring with them increased pest and public health concerns [ 65 , 66 , 67 , 68 ]. Importantly, there is growing evidence that there are interactions between invasive mosquitoes and endemic mosquitoes that share immature habitats that may be additionally influenced by a changing climate [ 69 , 70 , 71 ]. It is likely that the pathways of introduction, risk of incursion, and establishment of these invasive mosquitoes will required ongoing review.…”

Assessing the Risk of Exotic Mosquito Incursion through an International Seaport, Newcastle, NSW, Australia

Exotic mosquitoes, especially container-inhabiting species such as Aedes aegypti and Aedes albopictus, pose a risk to Australia as they bring with them potentially significant pest and public health concerns. Notwithstanding the threat to public health and wellbeing, significant economic costs associated with the burden of mosquito control would fall to local authorities. Detection of these mosquitoes at airports and seaports has highlighted pathways of introduction but surveillance programs outside these first ports of entry are not routinely conducted in the majority of Australian cities. To assist local authorities to better prepare response plans for exotic mosquito incursions, an investigation was undertaken to determine the extent of habitats suitable for container-inhabiting mosquitoes in over 300 residential properties adjacent to the Port of Newcastle, Newcastle, NSW. More than 1500 water-holding containers were recorded, most commonly pot plant saucers, roof gutters, and water-holding plants (e.g., bromeliads). There were significantly more containers identified for properties classified as untidy but there was no evidence visible that property characteristics could be used to prioritise property surveys in a strategic eradication response. The results demonstrate that there is potential for local establishment of exotic mosquitoes and that considerable effort would be required to adequately survey these environments for the purpose of surveillance and eradication programs.

“…We also downloaded images for the Normalized Difference Vegetation Index (NDVI) and Enhanced Vegetation Index (EVI), both of which are considered proxies for vegetation growth ( Pettorelli et al., 2005 ) and have been extensively used to study the ecology of mosquitoes ( Hurtado et al., 2018b ; Chaves et al., 2019 ; Poh et al., 2019 ; Rigg et al., 2019 ; Nguyen et al., 2020 ; Chaves & Friberg, 2021 ) and other insect vectors ( Kitron et al., 1996 ). The images for vegetation indices were downloaded for the multiple spatial scales encompassed by MODIS, Landsat 8 and Sentinel 2.…”
