Spatial and Temporal Distribution of Aedes aegypti and Aedes albopictus Oviposition on the Coast of Paraná, Brazil, a Recent Area of Dengue Virus Transmission

open access: yesTropical Medicine and Infectious Disease, 2022
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]

open access: yes, 2017
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

open access: yesJournal of the American Mosquito Control Association, 2007
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]

open access: yesMemórias do Instituto Oswaldo Cruz, 2002
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.

A time course analysis through diapause reveals dynamic temporal patterns of microRNAs associated with endocrine regulation in the butterfly Pieris napi

open access: yesMolecular Ecology, EarlyView.
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]

open access: yesarXiv, 2016
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.

Preimaginal development of Aedes aegypti L. (Diptera: Culicidae) in brackish water gives rise to adult mosquitoes with thicker cuticles and greater insecticide resistance

open access: yesMedical and Veterinary Entomology, EarlyView.
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 ...

Natural range expansion promotes stress resistance as a component of dispersal syndromes in non‐native insects

open access: yesOikos, EarlyView.
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]

open access: yes, 2019
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 ...

Molecular evidence of Wolbachia and Orthoflavivirus infection in field‐collected mosquitoes in three provinces of Türkiye

open access: yesTropical Medicine &International Health, EarlyView.
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 ...
