Aedes aegypti and Aedes albopictus are considered the most important vectors of arboviruses in the world. Aedes aegypti is the primary vector of dengue, urban yellow fever, chikungunya and zika in Brazil, and Ae.

Transmission dynamics of the ongoing chikungunya outbreak in Central Italy. From coastal areas to the metropolitan city of Rome, summer 2017 [PDF]
A large chikungunya outbreak is ongoing in Italy, with a main cluster in the Anzio coastal municipality. With preliminary epidemiological data, and a transmission model using mosquito abundance and biting rates, we estimated the basic reproduction number

PRESENCE OF AEDES ALBOPICTUS IN LEBANON AND SYRIA
The occurrence of Aedes albopictus in Lebanon and Syria is reported for the first time. Larvae were found in 4 localities in Lebanon, and 1 female was captured inside a house located in a coastal locality in Syria. The potential of the species to vector arboviral disease in the region is noted.

Genetic diversity in Brazilian populations of Aedes albopictus [PDF]
Random amplified polymorphic DNA (RAPD) analysis technique was undertaken in Aedes albopictus populations from three states in Brazil, Rio de Janeiro (RJ), Minas Gerais (MG) and Pernambuco (PE), to estimate the level of genetic variability and levels of genetic exchange between populations. Allele and genotype frequencies were measured on 47 RAPD loci.

Abstract Organisms inhabiting highly seasonal environments must cope with a wide range of environmentally induced challenges. Many seasonal challenges require extensive physiological modification to survive. In winter, to survive extreme cold and limited resources, insects commonly enter diapause, which is an endogenously derived dormant state ...

Research into the Potential to Adapt and Establish of the invasive Asian Tiger Mosquito Aedes (Stegomyia) albopictus (SKUSE) [PDF]
There is general agreement that the former (breeding) macrohabitat of the Asian tiger mosquito, Aedes albopictus (synonym: Stegomyia albopicta) has been described as phytotelmata in the forested areas of Southeast Asia, however, this has changed in the last four decades as it has adapted to more urban areas and antrotelmata.

The principal arboviral vector Aedes aegypti can develop in coastal brackish water field habitats (0.5–15 g/L salt) with larvae possessing thicker cuticles and greater resistance to the larvicide Temephos. Females emerging from brackish water‐developing preimaginal stages are now shown to have thicker and remodelled leg and abdominal cuticles and ...

Global changes and human activities have increased the likelihood of transport of non‐native insect species all around the globe. When established, the spread of organisms leads to the spatial sorting of the populations, progressively contributing to the selection of individuals with enhanced dispersal performance at the edges of the invaded range ...

Characterization of a broad-based mosquito yeast interfering RNA larvicide with a conserved target site in mosquito semaphorin-1a genes [PDF]
BACKGROUND: RNA interference (RNAi), which has facilitated functional characterization of mosquito neural development genes such as the axon guidance regulator semaphorin-1a (sema1a), could one day be applied as a new means of vector control ...

Abstract Background Mosquitoes transmit various pathogens causing diseases like Zika, Dengue, West Nile and Chikungunya. They also harbour insect‐specific viruses (ISVs) and Wolbachia, which can block arbovirus transmission. This study investigated the prevalence of Orthoflavivirus and Wolbachia in mosquito populations from three provinces in Türkiye ...
