Dengue, Zika and chikungunya viruses cause significant human public health burdens in the world. These arboviruses are transmitted by vector mosquito species notably Aedes aegypti and Aedes albopictus. In the Pacific region, more vector species of arboviruses belonging to the Scutellaris Group are present. Due to the expansion of human travel and international trade, the threat of their dispersal in other world regions is on the rise. Strengthening of entomological surveillance ensuring rapid detection of introduced vector species is therefore required in order to avoid their establishment and the risk of arbovirus outbreaks. This surveillance relies on accurate species identification. The aim of this study was to assess the use of the Matrix-Assisted Laser Desorption Ionization Time-Of-Flight Mass Spectrometry (MALDI-TOF MS) as a tool for an international identification and surveillance of these mosquito vectors of arboviruses. Field-mosquitoes belonging to 8 species (Ae. aegypti, Ae. albopictus, Aedes polynesiensis, Aedes scutellaris, Aedes pseudoscutellaris, Aedes malayensis, Aedes futunae and Culex quinquefasciatus) from 6 countries in the Pacific, Asian and Madagascar, were included in this study. Analysis provided evidence that a MALDI-TOF database created using mosquitoes from the Pacific region allowed suitable identification of mosquito species from the other regions. This technic was as efficient as the DNA sequencing method in identifying mosquito species. Indeed, with the exception of two Ae. pseudoscutellaris, an exact species identification was obtained for all individual mosquitoes. These findings highlight that the MALDI-TOF MS is a promising tool that could be used for a global comprehensive arbovirus vector surveillance.

“…Containers were thoroughly examined with a flashlight, and juvenile mosquitoes were collected using a standard spoon suitable for the size of the breeding habitat. The collected juveniles were transferred to glass containers using pipettes (11,18). The collected juveniles were placed in universal bottles and labeled with the date and time of collection, the zone and gridlines of the collection area, and the code of the container.…”

“…According to the studies, most natural breeding sites are coconuts and tree cavities. The most suitable artificial breeding containers, such as tires and plastic containers, are located near residential areas and are recycled (9)(10)(11)(12)(13)(14). In Africa, discarded car tires are reused as fencing, to weigh down tin roofs, and to reduce soil erosion.…”

Introduction: Poor waste management led to mosquito breeding grounds. Previous research found that construction sites are the mosquito breeding area thus it’s important to understand how construction sites affect mosquito breeding. Methods: This study utilized a prospective study to determine the characteristic of breeding preference in residential construction sites. On-field breeding preference survey was conduct in the selected project site in 12 weeks (1st October 2021 until 31st December 2021). Wet container inspection was carried out according to types of the residential construction building and progress of the site. All possible wet materials and containers was inspected and record accordingly in the form during the surveillance. Results: Result shows that the most preferred containers found was building floor (41.68%), others such as planter box that use for landscape purpose, drainage system, building mould and lift wells. The results of the research indicate that prospective containers with water and breeding sites at high rise construction sites were found to be more than those at low rise construction sites. Conclusion: Overall, substantially fewer water containers were discovered in low rise projects compared to high rise projects. Construction management need encourage all the workers to do best management practice such as proper waste disposal and removal of the water and possible wet container and conduct awareness among the workers.

“…Within the Culicidae family, mosquitoes comprise over 3600 species, categorized into two subfamilies and 113 genera 1 , 2 . Among these genera, the Aedes genus, specifically the Stegomyia subgenus, hosts numerous vector species 3 – 6 . As an example, Aedes ( Stegomyia ) aegypti, belonging to the Aegypti Group, is a major vector of dengue virus (DENV) and can also transmit several other arboviruses, including chikungunya (CHIKV), Yellow fever (YFV) and Zika viruses (ZIKV) 5 .…”

The Scutellaris Group of Aedes comprises 47 mosquito species, including Aedes albopictus. While Ae. albopictus is widely distributed, the other species are mostly found in the Asia–Pacific region. Evolutionary history researches of Aedes species within the Scutellaris Group have mainly focused on Ae. albopictus, a species that raises significant public health concerns, neglecting the other species. In this study, we aimed to assess genetic diversity and estimate speciation times of several species within the Scutellaris Group. Mosquitoes were therefore collected from various Asia–Pacific countries. Their mitochondrial cytochrome c oxidase subunit 1 (cox1) and subunit 3 (cox3) sequences were analyzed alongside those of other Scutellaris Group species available in the GenBank database. To estimate the divergence time, we analyzed 1849 cox1 gene sequences from 21 species, using three species (Aedes aegypti, Aedes notoscriptus and Aedes vigilax) as outgroups. We found that most of the speciation dates occurred during the Paleogene and the Neogene periods. A separation between the Scutellaris Subgroup and the Albopictus Subgroup occurred approximately 64–61 million years ago (MYA). We also identified a split between species found in Asia/Micronesia and those collected in Melanesia/Polynesia approximately 36–35 MYA. Our findings suggest that the speciation of Aedes species within the Scutellaris Group may be driven by diversity in mammalian hosts, climate and environmental changes, and geological dynamics rather than human migration.
