“…With the exception of Acre state, the presence of Aedes albopictus has been reported in all states of Brazil (Saraiva et al 2019;Ferreira-de-Lima et al 2020). Its spread in urban areas and its important capacity as a vector of arboviruses have been monitored in several studies (Arduino et al 2020;Honorio et al 2019;Melo Ximenes et al 2020).…”

New investigations using ovitraps showed its presence the Aedes albopictus (Skuse, 1894) in four neighborhoods in the metropolitan region of Macapa, capital of Amapa, Brazil. An Aedes aegypti (Linnaeus, 1762) Infestation Index Rapid Survey (LIRAa) held in January 2020 indicated the presence of Ae. albopictus in 10 different neighborhoods, demonstrating increase dispersion in the municipality. Monitoring the distribution of Ae. albopictus is necessary due to related arboviruses transmission, such as Dengue, Zika and Chikungunya. Therefore, this research is relevant to public health in Brazil.

“…Known as the Asian Tiger Mosquito, this species is considered a secondary vector for important arboviruses, such as Dengue, Zika, and Chikungunya (Paupy et al 2009;Smartt et al 2017). It has a wide distribution within Brazil (Carvalho et al 2014;Ferreira-de-Lima et al 2020).…”

“…There are two vectors present in Brazil capable of transmitting the dengue virus: Aedes aegypti and Aedes albopictus . Currently only Aedes aegypti are considered responsible for dengue transmission in Brazil [ 9 , 10 ], however a recent study identified Aedes albopictus infected by dengue virus in a rural area of Brazil during an outbreak, which could indicate their involvement in the introduction of dengue to rural areas [ 11 ]. Aedes aegypti have evolved to live in urban environments close to humans [ 12 ] but there is evidence to suggest they are becoming established in peri-urban and rural regions of South America [ 13 , 14 ].…”

The impact of climate suitability, urbanisation, and connectivity on the expansion of dengue in 21st century Brazil

et al. 2021

Dengue is hyperendemic in Brazil, with outbreaks affecting all regions. Previous studies identified geographical barriers to dengue transmission in Brazil, beyond which certain areas, such as South Brazil and the Amazon rainforest, were relatively protected from outbreaks. Recent data shows these barriers are being eroded. In this study, we explore the drivers of this expansion and identify the current limits to the dengue transmission zone. We used a spatio-temporal additive model to explore the associations between dengue outbreaks and temperature suitability, urbanisation, and connectivity to the Brazilian urban network. The model was applied to a binary outbreak indicator, assuming the official threshold value of 300 cases per 100,000 residents, for Brazil’s municipalities between 2001 and 2020. We found a nonlinear relationship between higher levels of connectivity to the Brazilian urban network and the odds of an outbreak, with lower odds in metropoles compared to regional capitals. The number of months per year with suitable temperature conditions for Aedes mosquitoes was positively associated with the dengue outbreak occurrence. Temperature suitability explained most interannual and spatial variation in South Brazil, confirming this geographical barrier is influenced by lower seasonal temperatures. Municipalities that had experienced an outbreak previously had double the odds of subsequent outbreaks. We identified geographical barriers to dengue transmission in South Brazil, western Amazon, and along the northern coast of Brazil. Although a southern barrier still exists, it has shifted south, and the Amazon no longer has a clear boundary. Few areas of Brazil remain protected from dengue outbreaks. Communities living on the edge of previous barriers are particularly susceptible to future outbreaks as they lack immunity. Control strategies should target regions at risk of future outbreaks as well as those currently within the dengue transmission zone.

Aedes albopictus diversity and relationships in south-western Europe and Brazil by rDNA/mtDNA and phenotypic analyses: ITS-2, a useful marker for spread studies

et al. 2021

Background Aedes albopictus is a very invasive mosquito, which has recently colonized tropical and temperate regions worldwide. Of concern is its role in the spread of emerging or re-emerging mosquito-borne diseases. Ae. albopictus from south-western Europe and Brazil were studied to infer genetic and phenetic diversity at intra-individual, intra-population and inter-population levels, and to analyse its spread. Methods Genotyping was made by rDNA 5.8S-ITS-2 and mtDNA cox1 sequencing to assess haplotype and nucleotide diversity, genetic distances and phylogenetic networks. Male and female phenotyping included combined landmark-and outlined-based geometric morphometrics of wing size and shape. Results Specimens from seven populations from Spain, France and Brazil provided 12 cox1 and 162 5.8S-ITS-2 haplotypes, with great genetic variability difference between both markers (0.9% vs 31.2%). Five cox1 haplotypes were shared with other countries, mainly Italy, USA and China, but none was shared between Europe and Brazil. The 5.8S-ITS-2 showed 2–7 intra-individual (mean 4.7) and 16–34 intra-/inter-population haplotypes (24.7), including haplotypes shared between Spain, France and Brazil. A 4.3% of ITS-2 haplotypes were shared, mainly with Italy, USA and Thailand, evidencing worldwide spread and introductions from areas where recent outbreaks of Ae. albopictus-transmitted pathogens occurred. Wing size showed sex differences. Wing shape distinguished between Brazilian and European specimens. Both genetic and morphometric markers showed differences between insular Spain and continental Spain, France and Brazil. Conclusions ITS-2 proves to be a useful marker to assess Ae. albopictus spread, providing pronouncedly more information than cox1, including intra-individual, intra-population and inter-population levels, furnishing a complete overview of the evolutionary exchanges followed by this mosquito. Wing morphometry proves to be a useful phenotyping marker, allowing to distinguish different populations at the level of both male and female specimens. Results indicate the need for periodic surveillance monitorings to verify that no Ae. albopictus with high virus transmission capacity is introduced into Europe. Graphic Abstract
