Newly recognized focus of La Crosse encephalitis in Tennessee. (1/2153)

La Crosse virus is a mosquito-borne arbovirus that causes encephalitis in children. Only nine cases were reported in Tennessee during the 33-year period from 1964-1996. We investigated a cluster of La Crosse encephalitis cases in eastern Tennessee in 1997. Medical records of all suspected cases of La Crosse virus infection at a pediatric referral hospital were reviewed, and surveillance was enhanced in the region. Previous unreported cases were identified by surveying 20 hospitals in the surrounding 16 counties. Mosquito eggs were collected from five sites. Ten cases of La Crosse encephalitis were serologically confirmed. None of the patients had been discharged from hospitals in the region with diagnosed La Crosse encephalitis in the preceding 5 years. Aedes triseriatus and Aedes albopictus were collected at the case sites; none of the mosquitos had detectable La Crosse virus. This cluster may represent an extension of a recently identified endemic focus of La Crosse virus infection in West Virginia.  (+info)

Sodalis gen. nov. and Sodalis glossinidius sp. nov., a microaerophilic secondary endosymbiont of the tsetse fly Glossina morsitans morsitans. (2/2153)

A secondary intracellular symbiotic bacterium was isolated from the haemolymph of the tsetse fly Glossina morsitans morsitans and cultured in Aedes albopictus cell line C6/36. Pure-culture isolation of this bacterium was achieved through the use of solid-phase culture under a microaerobic atmosphere. After isolation of strain M1T, a range of tests was performed to determine the phenotypic properties of this bacterium. Considering the results of these tests, along with the phylogenetic position of this micro-organism, it is proposed that this intracellular symbiont from G. m. morsitans should be classified in a new genus Sodalis gen. nov., as Sodalis glossinidius gen. nov., sp. nov. Strain M1T is the type strain for this new species.  (+info)

Vectors of Chikungunya virus in Senegal: current data and transmission cycles. (3/2153)

Chikungunya fever is a viral disease transmitted to human beings by Aedes genus mosquitoes. From 1972 to 1986 in Kedougou, Senegal, 178 Chikungunya virus strains were isolated from gallery forest mosquitoes, with most of them isolated from Ae. furcifer-taylori (129 strains), Ae. luteocephalus (27 strains), and Ae. dalzieli (12 strains). The characteristics of the sylvatic transmission cycle are a circulation periodicity with silent intervals that last approximately three years. Few epidemics of this disease have been reported in Senegal. The most recent one occurred in 1996 in Kaffrine where two Chikungunya virus strains were isolated from Ae. aegypti. The retrospective analysis of viral isolates from mosquitoes, wild vertebrates, and humans allowed to us to characterize Chikungunya virus transmission cycles in Senegal and to compare them with those of yellow fever virus.  (+info)

Variation in oral susceptibility to dengue type 2 virus of populations of Aedes aegypti from the islands of Tahiti and Moorea, French Polynesia. (4/2153)

Twenty three samples of Aedes aegypti populations from the islands of Tahiti and Moorea (French Polynesia) were tested for their oral susceptibility to dengue type 2 virus. The high infection rates obtained suggest that the artificial feeding protocol used was more efficient than those previously described. Statistical analysis of the results allowed us to define two distinct geographic areas on Tahiti with respect to the susceptibility of Ae. aegypti: the east coast, with homogeneous infection rates, and the west coast, with heterogeneous infection rates. No geographic differences could be demonstrated on Moorea. The possible mechanisms of this phenomenon are discussed in connection with recent findings on the variability of susceptibility of Ae. aegypti to insecticides.  (+info)

Replication of dengue type 2 virus in Culex quinquefasciatus (Diptera: Culicidae). (5/2153)

We were able to infect Culex quinquefasciatus by the parenteral route with dengue virus type 2. The percentage of mosquitoes infected was dose dependent and we obtained a rate of 45.6% infected Cx. quinquefasciatus when a 10(5.9) MID50 (mosquito infectious dose for 50% of the individuals as measured in Aedes aegypti) of dengue virus type 2 per mosquito was used. Infection was detected by an immunofluorescent assay performed on mosquito head squashes 14 days after infection. The replication of dengue virus in Cx. quinquefasciatus was either at a very low level of magnitude or generated a large number of noninfectious particles since the triturated bodies of infected Cx. quinquefasciatus did not infect Ae. aegypti mosquitoes when inoculated parenterally. We were unable to infect Cx. quinquefasciatus females orally with an artificial meal that infected 100% of Ae. aegypti females. These findings lead us to agree with the consensus that Cx. quinquefasciatus should not be considered a biological vector of dengue viruses.  (+info)

Interleukin-10 and antigen-presenting cells actively suppress Th1 cells in BALB/c mice infected with the filarial parasite Brugia pahangi. (6/2153)

Infection with the third-stage larvae (L3) of the filarial nematode Brugia results in a Th2-biased immune response in mice and humans. Previously we have shown that the production of interleukin 4 (IL-4) is critical for down-regulating polyclonal Th1 responses in L3-infected mice. However, the in vitro neutralization of IL-4 did not fully recover the defective polyclonal Th1 responses, nor did it result in the production of any antigen (Ag)-specific Th1 cytokines, suggesting that perhaps infection with L3 does not result in priming of Th1 cells in vivo. In this study, we analyzed the role of IL-10 and Ag-presenting cells (APCs) in the spleen as additional factors controlling the Th2 bias in infected mice. Our data show that IL-10 and APCs also contribute to the suppression of mitogen-driven Th1 responses of spleen cells from infected mice. In addition, the neutralization of IL-10 or the replacement of the resident APC population from spleen cell cultures resulted in the production of Ag-specific Th1 cytokines. Irradiated spleen cells from either L3-infected or uninfected mice were able to restore Ag-specific Th1 responses in vitro. Therefore, it appears that Brugia-reactive Th1 cells are primed following infection with L3, but are actively suppressed in vivo by a mechanism that involves IL-10 and the resident APC population, but not IL-4. These results indicate that a complex interplay of cytokines and cell populations underscores the Th2-polarized response in L3-infected mice.  (+info)

The cholesterol requirement for sindbis virus entry and exit and characterization of a spike protein region involved in cholesterol dependence. (7/2153)

Semliki Forest virus (SFV) and Sindbis virus (SIN) are enveloped alphaviruses that enter cells via low-pH-triggered fusion in the endocytic pathway and exit by budding from the plasma membrane. Previous studies with cholesterol-depleted insect cells have shown that SFV requires cholesterol in the cell membrane for both virus fusion and efficient exit of progeny virus. An SFV mutant, srf-3, shows efficient fusion and exit in the absence of cholesterol due to a single point mutation in the E1 spike subunit, proline 226 to serine. We have here characterized the role of cholesterol in the entry and exit of SIN, an alphavirus quite distantly related to SFV. Growth, primary infection, fusion, and exit of SIN were all dramatically inhibited in cholesterol-depleted cells compared to control cells. Based on sequence differences within the E1 226 region between SFV, srf-3, and SIN, we constructed six SIN mutants with alterations within this region and characterized their cholesterol dependence. A SIN mutant, SGM, that had the srf-3 amino acid sequence from E1 position 224 to 235 showed increases of approximately 100-fold in infection and approximately 250-fold in fusion with cholesterol-depleted cells compared with infection and fusion of wild-type SIN. Pulse-chase analysis demonstrated that SGM exit from cholesterol-depleted cells was markedly more efficient than that of wild-type SIN. Thus, similar to SFV, SIN was cholesterol dependent for both virus entry and exit, and the cholesterol dependence of both steps could be modulated by sequences within the E1 226 region.  (+info)

Genetic and fitness changes accompanying adaptation of an arbovirus to vertebrate and invertebrate cells. (8/2153)

The alternating host cycle and persistent vector infection may constrain the evolution of arboviruses. To test this hypothesis, eastern equine encephalitis virus was passaged in BHK or mosquito cells, as well as in alternating (both) host cell passages. High and low multiplicities were used to examine the effect of defective interfering particles. Clonal BHK and persistent mosquito cell infections were also evaluated. Fitness was measured with one-step growth curves and competition assays, and mutations were evaluated by nucleotide sequencing and RNA fingerprinting. All passages and assays were done at 32 degrees C to eliminate temperature as a selection factor. Viruses passaged in either cell type alone exhibited fitness declines in the bypassed cells, while high-multiplicity and clonal passages caused fitness declines in both types of cells. Bypassed cell fitness losses were mosquito and vertebrate specific and were not restricted to individual cell lines. Fitness increases occurred in the cell line used for single-host-adaptation passages and in both cells for alternately passaged viruses. Surprisingly, single-host-cell passage increased fitness in that cell type no more than alternating passages. However, single-host-cell adaptation resulted in more mutations than alternating cell passages. Mosquito cell adaptation invariably resulted in replacement of the stop codon in nsP3 with arginine or cysteine. In one case, BHK cell adaptation resulted in a 238-nucleotide deletion in the 3' untranslated region. Many nonsynonymous substitutions were shared among more than one BHK or mosquito cell passage series, suggesting positive Darwinian selection. Our results suggest that alternating host transmission cycles constrain the evolutionary rates of arboviruses but not their fitness for either host alone.  (+info)

Author Summary The Asian tiger mosquito, Aedes albopictus, is a highly invasive mosquito and has spread from South East Asia to Europe, the United States and northern areas of Asia in the past 30 years. Aedes mosquitoes transmit a range of viral diseases, including dengue and chikungunya. Aedes albopictus is generally considered to be somewhat less of a concern in this regard than Aedes aegypti. However a recent mutation in the chikungunya virus dramatically increased its transmission by Aedes albopictus, causing an important outbreak in the Indian Ocean in 2006 that eventually reached Italy in 2007. This highlights the potential importance of this mosquito, which can thrive much further from the Equator than can Aedes aegypti. This paper describes the first genetic engineering of the Asian tiger mosquito. This is an essential step towards the development of genetics-based control methods against this mosquito, and also an invaluable tool for basic research. We describe both transposon-based and site

The Asian tiger mosquito, Aedes albopictus, is a highly successful invasive species that transmits a number of human viral diseases, including dengue and Chikungunya fevers. This species has a large genome with significant population-based size variation. The complete genome sequence was determined for the Foshan strain, an established laboratory colony derived from wild mosquitoes from southeastern China, a region within the historical range of the origin of the species. The genome comprises 1,967 Mb, the largest mosquito genome sequenced to date, and its size results principally from an abundance of repetitive DNA classes. In addition, expansions of the numbers of members in gene families involved in insecticide-resistance mechanisms, diapause, sex determination, immunity, and olfaction also contribute to the larger size. Portions of integrated flavivirus-like genomes support a shared evolutionary history of association of these viruses with their vector. The large genome repertory may ...

The Goriška region and the town of Nova Gorica itself are a hotspot for reproduction and further spreading of many plant or animal non-native species. The reason for this are its transitional position and its mild climate. In recent years an invasive species known as the tiger mosquito (Aedes albopictus Skuse, 1894) has colonized this area. Here it successfully reproduces and maintains its population. In this paper we studied the seasonal dynamics of its reproduction from the appearance of first eggs until the development of the species larvae in various urban, suburban and forested locations. We studied the presence of tiger mosquito larvae in different surroundings and tried to determine its most suitable microhabitat. In order to acquire appropriate results we used ovitraps, which are commonly used to monitor mosquito larvae in their natural environment. At the end we examined the ratio between larvae of indigenous species and tiger mosquito larvae. The data were compared to shed light on ...

It wont be long before the Asian tiger mosquito makes its way onto U.S. soil. The CDC states that other mosquitoes that can spread the chikungunya virus and dengue are in the United States. These mosquitoes include Aedes aegypti and Aedes albopictus. Entomologists have found the species as far south as Floridas Gulf Coast and as far north and west as Chicago, Illinois.. ...
Aedes aegypti mosquitoes are primary vectors of dengue, yellow fever, chikungunya and Zika viruses. Ae. aegypti is highly anthropophilic and relies nearly exclusively on human blood meals and habitats for reproduction. Socioeconomic factors may influence the spread of Ae. aegypti due to its close relationship with humans. This paper describes and summarizes the published literature on how socioeconomic variables influence the distribution of Ae. aegypti mosquitoes in the mainland United States. A comprehensive search of PubMed/Medline, Scopus, Web of Science, and EBSCO Academic Search Complete through June 12, 2019 was used to retrieve all articles published in English on the association of socioeconomic factors and the distribution of Ae. aegypti mosquitoes. Additionally, a hand search of mosquito control association websites was conducted in an attempt to identify relevant grey literature. Articles were screened for eligibility using the process described in the Preferred Reporting Items for
Dengue is of great concern in various parts of the world, especially in tropical and subtropical countries where the mosquito vectors Aedes aegypti and Aedes albopictus are present. The transmission of this virus to humans, by what is known as horizontal transmission, occurs through the bite of infected females of one or other of the two mosquito species. Furthermore, an infected female or male parent, by what is known as vertical transmission, can transfer this arbovirus to some part of their offspring. Considering that vertical transmission may represent an important strategy for maintaining the circulation of arboviruses in nature, the verification of this phenomenon worldwide is extremely important and necessary to better understand its dynamic. In the present study, we conducted a literature review of the presence of natural vertical transmission of dengue virus in Ae. aegypti and Ae. albopictus worldwide. Searches were conducted in MEDLINE, sciELO and Lilacs and all the studies published in
Basseterre, St. Kitts, September 21, 2016 (SKNIS): Local retired entomologist Dr. Sam Rawlins said that it is possible to reduce the prevalence of the zika-carrying aedes aegypti mosquito if all members of the community become involved in what he terms "integrated vector management.". "Im preaching the message of integrated vector management for disease transmission interruption," Dr. Rawlins said. "And what I mean by that, is using all the tools that we have and using them in a rational combination of all the methods. We and our partners can collaborate in reducing these habitats and using the various tools because theres a whole range of tools that we have.". Dr. Rawlins explained that while there are approximately 13 species of mosquito on-island, the one that causes the greatest threat is the aedes aegypti mosquito because of its disease-carrying capability.. The integrated method includes using tools such as environmental control that involves emptying and removing containers that can ...
CITY NEWS SERVICE. EL MONTE - An aggressive species of mosquito responsible for outbreaks of dengue virus in Florida, Hawaii and Texas has been found in El Monte, officials said Tuesday.. Asian tiger mosquitoes are aggressive biters and active during daylight hours, as well as at dusk and dawn, according to the San Gabriel Valley Mosquito and Vector Control District, the agency responsible for mosquito control in the area.. "Our goal is to eradicate this population," said Kenn Fujioka, the districts assistant manager. "We definitely do not want this mosquito to become established in our communities.". The black-and-white striped insect, about a quarter-inch long, is a native of tropical and subtropical Southeast Asia and has not been seen in the San Gabriel Valley since 2001, when they were accidentally imported in shipments of plants called "Lucky Bamboo.". The pest can transmit many serious diseases, including dengue fever, yellow fever; chikungunya, which is similar to dengue fever; ...
Background Dengue and chikungunya are global re-emerging mosquito-borne diseases. In Singapore, sustained vector control coupled with household improvements reduced domestic mosquito populations for the past 45 years, particularly the primary vector Aedes aegypti. However, while disease incidence was low for the first 30 years following vector control implementation, outbreaks have re-emerged in the past 15 years. Epidemiological observations point to the importance of peridomestic infection in areas not targeted by control programs. We investigated the role of vectors in peri-domestic areas. Methods We carried out entomological surveys to identify the Aedes species present in vegetated sites in highly populated areas and determine whether mosquitoes were present in open-air areas frequented by people. We compared vector competence of Aedes albopictus and Aedes malayensis with Ae. aegypti after oral infection with sympatric dengue serotype 2 and chikungunya viruses. Mosquito saliva was tested ...

The Asian tiger mosquito is an invasive mosquito species that is known to be a vector for a wide range of mosquito-borne illness and disease. Learn more on our blog.
Aedes aegypti is the principal vector of the etiological agents of yellow fever, dengue fever and chikungunya fever. In 1901, Walter Reed and colleagues showed that yellow fever was transmitted by Aedes aegypti. Their work was based on Carlos Finlays hypothesis that mosquito bites could transmit the organism causing the disease. Due to its easy adaptation to laboratory culture it is the most studied species within the Culicinae, and has extensively contributed to our understanding of mosquito biology, physiology, genetics, and vector competence.. The Aedes aegypti complete genome sequence was first published in 2007. About 47% of the genome consists of transposable elements, probably contributing to the expansion in size and organization of the Aedes aegypti genome over time. ...

At present, the northernmost breeding populations of this species in Europe occur in Freiburg [2], Heidelberg and Jena, Germany (Norbert Becker, personal communication, June 2016). A further spread of Ae. albopictus into the Rhine rift valley and parts of Bavaria and North Rhine-Westphalia, Germany, is very likely due to climatic habitat suitability and man-made features [3, 4]. Apart from the frequently suboptimal low temperatures in these regions, the establishment of Ae. albopictus may be modulated by interactions with resident container-breeding mosquitoes [5-7].. Aedes albopictus was shown to be a strong competitor for resident mosquito species such as Aedes triseriatus as well as exotic species like Aedes aegypti in the United States of America [7, 8]. However, ...
Arthropod-borne viruses (arboviruses) can persistently infect and cause limited damage to mosquito vectors. RNA interference (RNAi) is a mosquito antiviral response important in restricting RNA virus replication and has been shown to be active against some arboviruses. The goal of this study was to use a recombinant Sindbis virus (SINV; family Togaviridae; genus Alphavirus) that expresses B2 protein of Flock House virus (FHV; family Nodaviridae; genus Alphanodavirus), a protein that inhibits RNAi, to determine the effects of linking arbovirus infection with RNAi inhibition. B2 protein expression from SINV (TE/32J) inhibited the accumulation of non-specific small RNAs in Aedes aegypti mosquito cell culture and virus-specific small RNAs both in infected cell culture and Ae. aegypti mosquitoes. More viral genomic and subgenomic RNA accumulated in cells and mosquitoes infected with TE/32J virus expressing B2 (TE/32J/B2) compared to TE/32J and TE/32J virus expressing GFP. TE/32J/B2 exhibited increased

Twenty-six GST genes are present in Ae. aegypti, two of which are alternatively spliced to give a total of 29 transcripts for cytosolic GSTs. The six classes identified in other insect species are all represented and, as in Anopheles gambiae, the majority of the mosquito GSTs belong to the insect-specific Delta and Epsilon ...
Scientists from Goethe University and Senckenberg Society for Nature Research are developing maps on the Zika virus infection risk. The spread of infectious diseases such as Zika depends on many different factors. Environmental factors play a role, as do socioeconomic factors. Recently, several attempts have be made to predict the transmission risk of the Zika virus at a global and local level, but the spatial and temporal patterns of transmission are still not well understood. Researchers from Goethe University and the Senckenberg Society for Nature Research in Frankfurt were now able to generate reliable maps for the transmission risk of the Zika virus in South America. The results have been published in the scientific journal "PeerJ". Based on the models for South America, they will use the method to determine the Zika risk for Europe as well.. In most cases, mosquitoes of the genus Aedes transmit the Zika virus to humans. Primary vectors are the yellow fever mosquito (Aedes aegypti) and the ...
Such a high economic cost drives many attempts to find a solution; while dengue vaccines are being developed, most countries focus on vector control. This involves studying the biology and physiology of the vector, in this case, Ae. albopictus, in the hopes of understanding ways to control or limit the spread of the vector, and hence, any associated zoonotic diseases. In Singapore, many studies 49 43 45 50 have been funded to understand Ae. albopictus. This increased understanding of the various mosquito vectors in our environment in turn enables better policy-making, to better combat this public health issue. However, this is not a process that is close to completion. New emerging infectious diseases are always on the horizon; zika virus (ZIKV) is one of these potential new arboviruses 51 . While zika virus is usually spread by Ae. aegypti, Ae. albopictus has recently been proven to have potential to spread ZIKV 51 .

Abstract. Diurnal temperature fluctuations can fundamentally alter mosquito biology and mosquito-virus interactions in ways that impact pathogen transmission. We investigated the effect of two daily fluctuating temperature profiles on Aedes aegypti vector competence for dengue virus (DENV) serotype-1. A large diurnal temperature range of 18.6°C around a 26°C mean, corresponding with the low DENV transmission season in northwestern Thailand, reduced midgut infection rates and tended to extend the virus extrinsic incubation period. Dissemination was first observed at day 7 under small fluctuations (7.6°C; corresponding with high DENV transmission) and constant control temperature, but not until Day 11 for the large diurnal temperature range. Results indicate that female Ae. aegypti in northwest Thailand are less likely to transmit DENV during the low than high transmission season because of reduced DENV susceptibility and extended virus extrinsic incubation period. Better understanding of DENV

Phylogenetic studies have shown that ZIKV has evolved into African and Asian lineages. The Asian lineage of ZIKV was responsible for the recent epidemics in the Americas. However, the underlying mechanisms through which ZIKV rapidly and explosively spread from Asia to the Americas are unclear. Non-structural protein 1 (NS1) facilitates flavivirus acquisition by mosquitoes from an infected mammalian host and subsequently enhances viral prevalence in mosquitoes. Here we show that NS1 ...
Trinidad and Tobago, May 5, 2017 - Port of Spain - "Community participation is critical to the success of any programme designed to eliminate breeding sites of the Aedes aegypti mosquito. Efforts are doomed to failure if even one household is negligent." So said Dr C James Hospedales, Executive Director of the Caribbean Public Health Agency (CARPHA), as he commented on the importance of Caribbean Mosquito Awareness Week, which is being observed from May 8-12. In his assessment of the mosquito prevention efforts in the Region thus far, Dr Hospedales noted that strategies for the control of the mosquito, which causes Dengue, Chikungunya and Zika are failing, and stated that what is needed is an "all hands onboard approach." Dr Karen Polson Edwards, CARPHA Assistant Director of Surveillance, Disease Prevention Control, supports this "all hands onboard approach perspective" as she said, "mosquitoes are social creatures and we are their preferred host. Their breeding sites are mostly man-made water ...
Zika virus is spread through the bite of infected mosquitoes in the Aedes genus, the same mosquitoes that carry dengue fever and chikungunya.. The primary carrier, Aedes aegypti, also called yellow fever mosquito, is found predominantly in tropical and sub-tropical regions of the United States.. Aedes albopictus mosquitoes are also presumed to transmit the virus. This species, commonly known as the Asian tiger mosquito, has a much wider distribution in the U.S and in addition to the southeast, is found in northeastern and mid-west states.. Other diseases transmitted by mosquitoes, include Malaria, West Nile virus, Yellow fever, Filariasis, Dengue fever and Encephalitis kill and debilitate millions of persons worldwide even with todays advances in medicine.. ...

We know that Aedes aegypti and Aedes albopictus mosquitoes prefer not to share their oviposition sites with each other. However, they are excited to share amongst individuals of their own species. We will touch more on this phenomenon in a future post. It is also reasonable to assume that we cannot control all potential oviposition sites in a real world scenario. Can these pieces be used in a solution?. A 2003 study at North Carolina State University found that the insect growth regulator pyriproxyfen was effective at inhibiting the development from larva to adult Aedes mosquito. At only 0.2 parts per billion (approximately 0.2 micrograms per liter water), pyriproxyfen kept 50% of Aedes albopictus larvae from reaching adulthood. This is such a small amount of pyriproxyfen that it could be transferred to an untreated or uncontrolled oviposition site on the legs of ovipositing mosquitoes. A single female visiting a clean container reduced adult emergence by 4-30%, but it could reduce adult ...

Five species of invasive Aedes mosquitoes have recently become established in Europe: Ae. albopictus, Ae. aegypti, Ae. japonicus japonicus, Ae. koreicus and Ae. atropalpus. These mosquitoes are a serious nuisance for people and are also competent vectors for several exotic pathogens such as dengue and chikungunya viruses. As they are a growing public health concern, methods to control these mosquitoes need to be implemented to reduce their biting and their potential for disease transmission. There is a crucial need to evaluate methods as part of an integrated invasive mosquito species control strategy in different European countries, taking into account local Aedes infestations and European regulations. This review presents the control methods available or in development against invasive Aedes mosquitoes, with a particular focus on those that can be implemented in Europe. These control methods are divided into five categories: environmental (source reduction), mechanical (trapping), biological ...

TY - JOUR. T1 - The Gr family of candidate gustatory and olfactory receptors in the yellow-fever mosquito Aedes aegypti. AU - Kent, Lauren B.. AU - Walden, Kimberly K.O.. AU - Robertson, Hugh M. PY - 2008/1/1. Y1 - 2008/1/1. N2 - The gustatory receptor (Gr) protein family contains most of the diversity in the insect chemoreceptor superfamily, including within it not only taste receptors but select olfactory receptors as well. Manual annotation of the Gr family in the genome sequence of the yellow-fever mosquito, Aedes aegypti , yielded a total of 114 potential proteins encoded by 79 genes. In the sequenced genome, 23 of these genes and protein isoforms are pseudogenic, leaving 91 putatively functional Grs. Comparison with our previously published set of 76 Grs encoded by 52 genes in the distantly related Anopheles gambiae mosquito revealed 13 new AgGrs encoded by 8 genes. Phylogenetic analysis reveals the conservation of carbon dioxide, sugar, and several orphan receptors in these 2 mosquitoes ...

The control of dengue fever depends on the level of Aedes aegypti infestation and thus relies heavily on the measures for controlling the vector. Quite recently, despite the implementation of mosquito control measures, the Aedes aegypti population has still escalated. The vector apparently has adapted to or resisted most of the control methods. The failure of Aedes aegypti control programmes has been blamed on the vectors biological features fostering the development of species resistance to chemical control or environmental factors favouring the increase of the Aedes aegypti population at a faster rate than the control methods can reduce them. Nevertheless, many Aedes aegypti control programmes are improperly planned and implemented or the control measures are often used as reactive methods of controlling dengue fever outbreaks, rather than as continuous proactive strategies preventing disease. Aedes aegypti breeding is basically a problem of domestic sanitation and therefore communities have ...
Abstract: The Asian tiger mosquito is an invasive species showing a continuous expansion in the Mediterranean basin in general and in Spain in particular. The first detection of Aedes albopictus in mainland Spain was reported in 2004. Eight years later, in 2012, this mosquito species was detected in the Balearic archipelago, specifically on Majorca. In 2014 it was detected on Eivissa, another island from this archipelago. In this paper we report for the first time the presence of Ae. albopictus on the island of Minorca. Journal of the European Mosquito Control Association 34: 5-9, 2016. ...
Zika is primarily spread by the female Aedes aegypti mosquito, which is active mostly in the daytime.[44][45] The mosquitos must feed on blood to lay eggs.[46]:2 The virus has also been isolated from a number of arboreal mosquito species in the genus Aedes, such as A. africanus, A. apicoargenteus, A. furcifer, A. hensilli, A. luteocephalus, and A. vittatus, with an extrinsic incubation period in mosquitoes around 10 days.[21]. The true extent of the vectors is still unknown. Zika has been detected in many more species of Aedes, along with Anopheles coustani, Mansonia uniformis, and Culex perfuscus, although this alone does not incriminate them as vectors.[45] To detect the presence of the virus usually requires genetic material to be analysed in a lab using the technique RT-PCR. A much cheaper and faster method involves shining a light at the head and thorax of the mosquito, and detecting chemical compounds characteristic of the virus using near-infrared spectroscopy.[47]. Transmission by A. ...
The Aedes albopictus ("Asian Tiger") mosquitoes which can transmit Zika, Chikungunya, and Dengue Fever viruses, have adapted very well to human habitats, by being able to lay eggs that survive long periods without water and that can hatch and grow into larvae after a rain shower in a container as small as a bottle cap. Differing greatly in habitat from the more familiar marsh mosquitos that thrive near marshes in tidal zones, the Asian Tiger mosquitos, with recognizable white striped legs, feeds during daylight hours when people are most likely to be outside, versus the marsh mosquitoes that primarily feed at dusk.. There are many things that families on the Eastern Shore of Virginia can do to protect themselves from mosquitos on their own property and in their community:. 1.

Link to Pubmed [PMID] - 30753180. PLoS Negl Trop Dis 2019 Feb;13(2):e0007116. BACKGROUND: Transmission of dengue virus (DENV) from humans to mosquitoes represents a critical component of dengue epidemiology. Examinations of this process have generally been hampered by a lack of methods that adequately represent natural acquisition of DENV by mosquitoes from humans. In this study, we assessed artificial and natural blood feeding methods based on rates of DENV infection and dissemination within mosquitoes for use in a field-based epidemiological cohort study in Iquitos, Peru.. METHODOLOGY/PRINCIPAL FINDINGS: Our study was implemented, stepwise, between 2011 and 2015. Participants who were 5 years and older with 5 or fewer days of fever were enrolled from ongoing clinic- and neighborhood-based studies on dengue in Iquitos. Wild type, laboratory-reared Aedes aegypti were fed directly on febrile individuals or on blood collected from participants that was either untreated or treated with EDTA. ...
Beyond Pesticides, May 1, 2017) The Florida Keys Mosquito Control District released 20,000 male mosquitoes infected with Wolbachia bacteria near Key West, as a trial strategy to manage mosquitoes that carry Zika and other viruses. The district and others have been exploring new ways to suppress infected Aedes aegypti mosquito populations, which thrive in urban environments and can spread Zika, dengue fever, and chikungunya. It is unclear what impacts, if any, these infected mosquitoes will have on non-target organisms or public health. The trial is the second U.S. test conducted with the naturally occurring Wolbachia bacteria in Aedes aegypti mosquitoes, developed by the Kentucky-based company MosquitoMate. The first test occurred in Clovis, California, last year. In September 2016, the U.S. Environmental Protection Agency (EPA), which registers mosquito control products, approved and expanded an experimental use permit (EUP) for Wolbachia pipientis-infected Aedes aegypti mosquitoes (not to be ...
