Coquillettidia is a mosquito genus erected by entomologist Harrison Gray Dyar, Jr. in 1904 based primarily on unique features of its peculiar male genitalia. The specific epithet honors Dyars colleague Daniel William Coquillett. The genus comprises three subgenera, Austromansonia, Coquillettidia, and Rhynochotaenia, and 57 species, of which Coquillettidia perturbans is perhaps the best known. Not all species have been well documented, but females of some are known to feed primarily on birds but will also bite cattle. The females bite primarily at night, and are most active during the early part of the night. They occasionally attack humans during daylight hours in shady places when their habitat is entered. Adult females lay their eggs on the surface of water in areas of emergent vegetation to which hatchling larvae attach themselves with a modified siphon, on the roots or submerged stems, and where they remain throughout development; pupae also attach themselves the plants by means of a ...

The study is the first to document the rise of mutations that make mosquitoes resistant to a gene drive, due to natural selection. These findings will allow researchers to make better predictions of how a gene drive will proceed and to improve the design of future gene drives to decrease the likelihood of resistance.. Tony Nolan adds: Reducing the numbers of mosquito vectors has been the most effective tool to date for the control of malaria, so self-sustaining gene drives designed with this purpose have great potential. However gene drives are not a silver bullet and just like antibiotics can select for resistance in bacteria, gene drives can be susceptible to resistance at their target site. The novelty of this study is not that resistance emerges - we have been planning strategies to deal with this from the start - but that it documents the way it emerges and the way it is selected over generations. This work will help a lot in planning for and managing the emergence of ...

One of the main concerns over gene drive is its potential long‐term effects. The designated effects on the targeted populations will be fast-within a few years-while long‐term effects on ecosystems may take decades to appear and are extremely unpredictable. The time frame of gene drive perfectly fits the economic development strategies dominant today in agribusiness, with a focus on short‐term return on investments and disdain for long‐term issues. The current economical system based on productivity, yields, monoculture, and extractivism [7] is a perfect match for the operating mode of gene drive. In addition, agri‐food industry decision centers are rarely located near the production sites. They will be inclined to disregard the ecological long‐term risks as they only concern local human populations in their exploited lands. Gene drive then becomes an issue of environmental justice.. The scarce use of gene drive, if concerted, cautious and controlled, may not cause any ecological ...

In the past decade, researchers have engineered an array of new tools that control the balance of genetic inheritance. Based on CRISPR technology, such gene drives are poised to move from the laboratory into the wild where they are being engineered to suppress devastating diseases such as mosquito-borne malaria, dengue, Zika, chikungunya, yellow fever and West Nile. Gene drives carry the power to immunize mosquitoes against malarial parasites, or act as genetic insecticides that reduce mosquito populations.. Although the newest gene drives have been proven to spread efficiently as designed in laboratory settings, concerns have been raised regarding the safety of releasing such systems into wild populations. Questions have emerged about the predictability and controllability of gene drives and whether, once let loose, they can be recalled in the field if they spread beyond their intended application region.. Now, scientists at the University of California San Diego and their colleagues have ...

The African Unions High-Level Panel on Emerging Technologies identified gene drive mosquitoes as a priority technology for malaria elimination. The first field trials are expected in 5-10 years in Uganda, Mali or Burkina Faso. In preparation, regional and international actors are developing risk governance guidelines which will delineate the framework for identifying and evaluating risks. Scientists and bioethicists have called for African stakeholder involvement in these developments, arguing the knowledge and perspectives of those people living in malaria-afflicted countries is currently missing. However, few African stakeholders have been involved to date, leaving a knowledge gap about the local social-cultural as well as ecological context in which gene drive mosquitoes will be tested and deployed. This study investigates and analyses Ugandan stakeholders hopes and concerns about gene drive mosquitoes for malaria control and explores the new directions needed for risk governance.

Scientists are close to figuring out how a tiny, pesky mosquito can survive a virus that kills humans millions of times its size. The blood-sucking insect creates an immediate and potent immunity not strong enough to kill the virus but strong enough to save the mosquitos life, according to new research from Colorado State University. The finding could bring scientists closer to eradicating mosquito-borne diseases such as dengue fever, West Nile, yellow fever and Japanese encephalitis. Years from now, scientists might genetically modify mosquitoes that are fully immune to viruses, CSU researchers said. They would release these stronger, more robust mosquitoes into the wild to win the battle of natural selection - the fittest mosquitoes eventually would replace the ones run down by carrying viruses in their bodies. You cant fight evolution, said Dr. Carol Blair, professor of microbiology, immunology and pathology, and a study author. Youve got to figure out how to manipulate it. Genetically ...

I bet you would be surprised to learn that since we began to collect Mosquito Habitat Mapper data (5/29/2017), we have had over 20,915 observations submitted! Think about how significant that number is for a tool that has only been available for less than three years! As many of us who live in the northern hemisphere begin to see signs of spring arriving- robins, crocuses, leaf buds on the trees, and warmer weather- we know that we will also see adult mosquitoes before too long. While there are over 3,500 species of mosquitoes, only about 100 of those species are actually dangerous to humans. When we are bit by a mosquito, it is the adult female with eggs who bites us. Both male and female mosquitoes get their food from pollen, but the female needs a blood meal to supply her eggs with protein so they will be viable.. When we get bit by mosquitoes, that is when we can contract a disease. With the Mosquito Habitat Mapper, you are helping to reduce the threat of mosquito-transmitted disease ...

In regard to the places with the most abundant mosquito population, Africa is the continent which reports the most mosquito-borne diseases each year.. But also, in Asia and South America, there are far more mosquito-borne diseases than the rest of the world. However, these often go unreported in some nations. Regardless of reporting inaccuracies, these mosquito-borne diseases have become a significant cause of human fatalities.. One reason for this is that most mosquito-borne diseases do not have effective vaccines available. And the seemingly ever-increasing enormous mosquito population does not help science to solve this escalating problem.. Mosquito-borne viruses kill more than a million people each year, and over a billion people suffer long-term consequences like brain damage, blindness, serious illness, and debilitating pain.. Some of the most impactful and well-known diseases reported by medical professionals practicing in mosquito-prone regions are dengue fever, yellow fever, malaria, ...

If mosquito bites seem to be associated with more-serious warning signs - such as fever, headache, body aches and signs of infection - contact your doctor.. Mosquito bites are caused by female mosquitoes feeding on your blood. Female mosquitoes have a mouthpart made to pierce skin and siphon off blood. Males lack this blood-sucking ability because they dont produce eggs and so have no need for protein in blood.. As a biting mosquito fills itself with blood, it injects saliva into your skin. Proteins in the saliva trigger a mild immune system reaction that results in the characteristic itching and bump.. Mosquitoes select their victims by evaluating scent, exhaled carbon dioxide and the chemicals in a persons sweat.. Scratching bites can lead to infection.. Mosquitoes can carry certain diseases, such as West Nile virus, malaria, yellow fever and dengue fever. The mosquito obtains a virus or parasite by biting an infected person or animal. Then, when biting you, the mosquito can transfer that ...

Scientists have issued a call to ensure that the use of gene drives in conservation will only affect local populations. Gene drives promote the inheritance of a particular genetic variant to increase its frequency in a population. In conservation, a gene drive could spread infertility and ultimately eliminate a pest population.

The only connection the article offers to global warming is the assertion that the tiger mosquitos habitat has expanded steadily northward as temperatures have risen, as though there had been some significant rise in temperatures over the last ten years and that this rise was a prerequisite to the enlargement of the mosquitos habitat, at least in a northerly direction. Yet the facts are that global mean temperature has risen a scant .7◦C (1.26◦F) over the entire period since 1900 and, according to data supplied by The University of East Anglia and The Hadley Centre, global mean temperatures have actually been modestly declining since 1998! (For verification of this last point, see the website http://www.eurekalert.org/pub_releases/2007-12/uoea-awy121207.php). Moreover, since temperature lows in the region of Italy where the outbreak occurred are lower than those in most of France and England by 1 or 2 degrees Celsius, temperature conditions in those areas, which are considerably further ...

A number of other respondents have brought up developments in gene drives (e.g. development of mammalian gene drive systems). In 2018 ETC Group released an overview report on the application of gene drive systems to agriculture (See Forcing the Farm: http://www.etcgroup.org/content/forcing-farm) which we hereby submit for consideration of new developments in the field. Our research show that there is increasing work on application of gene drive systems to agricultural pests (Especially insects and aphids) as well as to applying gene drive as a breeding tool for livestock. To date we cannot identify successful use of CRISPR gene drive systems in plants (although perhaps others on this forum can correct that) or any working examples of so called local or controllable gene drive systems beyond theoretical models. Given that some of these theoretical ideas are advanced in policy fora as if they exist I think it may be important for the moderators in their summary of this forum to also point to and ...

She says most of them are aedes sollicitans, a name that doesnt roll off the tongue, but seems to have teeth.. These mosquitoes will fly during the day, they fly really far, Clark said. Theyre strong flyers. They can travel up to 25 miles with the wind, so theyre going to get you anywhere.. Sollicitans, she said have prospered close to the ocean especially since Sunday. Its because the noreaster that hit the First Coast two weekends ago gave mosquitoes a leg up all while leaving spray-and-fog technicians to catch up.. The tides were really high. There were some areas that we really werent able to, to treat, and once they came off, this is what happened.. Clark said salt marshes are perfect for these mosquitoes to breed because the marshes offer relatively still water, plenty of shelter, and lack of predation from fish. Like the psorophora species that hatched post-Irma, they dont carry disease, but their bite is more painful than most.. They are really aggressive and they are a big ...

You might not be able to pronounce the name of the latest rampant mosquito-borne viral infection, but youd probably never forget chikungunya if you caught it.

In a crowded auditorium at New Yorks Cold Spring Harbor Laboratory in August, Philipp Messer, a population geneticist at Cornell University, took the stage to discuss a powerful and controversial new application for genetic engineering: gene drives.. Gene drives can force a trait through a population, defying the usual rules of inheritance. A specific trait ordinarily has a 50-50 chance of being passed along to the next generation. A gene drive could push that rate to nearly 100 percent. The genetic dominance would then continue in all future generations. You want all the fruit flies in your lab to have light eyes? Engineer a drive for eye color, and soon enough, the fruit flies offspring will have light eyes, as will their offspring, and so on for all future generations. Gene drives may work in any species that reproduces sexually, and they have the potential to revolutionize disease control, agriculture, conservation and more. Scientists might be able to stop mosquitoes from spreading ...

He has led the movement to shine the spotlight, says Marc Lipsitch, an epidemiologist at Harvard University involved in biosafety issues. Its not that common to be at the beginning of your career and already be thinking of the moral, ethical, and policy implications.. A gene drive is a genetic addition made to a mosquito or other organism that is able to spread through a population of animals in the wild and potentially act as a doomsday gadget, driving it out of existence. The technology presents challenges not only because it could extinguish a species but because by its very nature it can spread widely, including as the result of a lab accident.. This is the perfect example of a technology that needs to be community-guided from the beginning, says Esvelt. Its meaningless to talk about engaging the public in science if science is still going to develop the product and then say, What do you think?. Esvelt says hes started a new project, called Responsive Science, along with MIT ...

Gene drive systems distort the rule that there is a 50:50 chance of a gene copy being passed on. This promotes the inheritance of a particular copy of a gene from the parent to offspring. When coupled to a genetic trait that affects an individuals survival or ability to reproduce, it becomes a powerful tool that can be used for population control or even local elimination.

Most people think summer is the only time to be concerned about mosquitoes. However, in the mid-Atlantic, once temperatures stay consistently warm, mosquitoes start to emerge. We cant pinpoint the exact start of mosquito season, but it is safe to say its right around the corner. Mosquitoes that hibernated need consistent warm temperatures to become active, while mosquitoes that spent the winter as eggs need rainfall in order to hatch. That makes the month of April a perfect time for their emergence. Peak season doesnt occur until July and August, but now is the time to get your yard ready and be aware of how you can prevent mosquitoes from laying eggs in your yard.. Mosquitoes can be an annoyance around your yard. Their bites, while undetected as they occur, leave you with itchy red bumps that can irritate and take days to go away. Why is this? Female mosquitoes are the ones responsible for the bite. Although technically not a real bite, since they dont have teeth and use their long ...

This is a huge public health emergency and horrible on many levels, says Uriel Kitron, chair of Emorys Department of Environmental Sciences and an expert in vector-borne diseases, which are transmitted by mosquitoes, ticks or other organisms.

The costs to the public health system will be enormous, and Brazil was already experiencing an economic crisis ...

An eletrophoretic analysis of three species of the subgenus Dendromyia (Wyeomyia luteoventralis, Wy. ypsipola and Wy. testei) and three species belonging to different groups in the genus Wyeomyia (Wy. negrensis, Wy. mystes and Wy.confusa) was performed. Eight enzyme loci were analyzed. High values of genetic identity were detected among the species of the subgenus Dendromyia: Wy. luteoventralis, Wy. ypsipola and Wy. testei (mean value 0.63). On the other hand low values of genetic identity were observed among Wy. negrensis, Wy. mystes and Wy. confusa (mean value 0.23), suggesting that they belong, at least, to distinct subgenera within the Genus Wyeomyia. The UPGMA phenogram revealed the grouping of the Dendromyia species, while the others clustered at lower identity levels ...

A recent article highlights some of these new technologies for monitoring lymphatic filariasis (LF) control programmes. In this paper, Zaky and colleagues detail trials of a field laboratory that fits in a backpack and weighs less than 10 lbs! The assay can extract DNA from mosquitoes (vectors of LF), amplify this DNA with a special tag, and then use this tag to visualise DNA on a test strip. A test band, in addition to the control, confirms that a mosquito has LF. They tried pooling mosquitoes, so more than one mosquito can be tested at once. The test is so sensitive that it can detect one larvae in a pooled sample of 25 mosquitoes. Although this test is currently quite expensive ($7.50 for a pool of mosquitoes), costs should decline in the coming years.. These field laboratories are increasingly being used for in depth studies - not just detecting small organisms but quantifying whole genomes. New technologies have been used in space, during the 2014 West African Ebola Outbreak, and to study ...

N2 - A new stage-structured model for the population dynamics of the mosquito (a major vector for numerous vector-borne diseases), which takes the form of a deterministic system of non-autonomous nonlinear differential equations, is designed and used to study the effect of variability in temperature and rainfall on mosquito abundance in a community. Two functional forms of eggs oviposition rate, namely the Verhulst-Pearl logistic and Maynard-Smith-Slatkin functions, are used. Rigorous analysis of the autonomous version of the model shows that, for any of the oviposition functions considered, the trivial equilibrium of the model is locally- and globally-asymptotically stable if a ...

Relative humidity drops to levels that are uncomfortable for mosquitoes at the end of the rainy season. In one village, Banizoumbou, water pools dried up and interrupted mosquito breeding shortly after the end of the rainy season. In this case, relative humidity had little effect on the mosquito population. However, in the other village, Zindarou, the relatively shallow water table led to water pools that persisted several months beyond the end of the rainy season. In this case, the decrease in mosquito survival due to relative humidity improved the models ability to reproduce the seasonal pattern of observed mosquito abundance ...

Tomarken announced today that 15 mosquito samples (all Culex pipiens-restuans) collected between August 22 and August 28, 2016, have tested positive for West Nile virus. The samples were collected from Islip (1), Smithtown (1), Rocky Point (1) Huntington Station (1), South Huntington (1), Huntington (1), Holtsville (3), North Patchogue (1), Farmingville (1), Setauket (2), Copiague (1), and West Babylon (1).. ...

Using murine peritoneal macrophages and lymphocytes, and human peripheral mononuclear cells (PBMCs), this study shows that saliva of the female Ar. subalbatus induces apoptosis via interaction with the Fas receptor within a few hours but without activating caspase-8. The process further activates downstream p38 MAPK signaling, a cascade that leads to the induction of apoptosis in capase-3 dependent manner. We further illustrate that Ar. subalbatus saliva suppresses proinflammatory cytokines without changing IL-10 levels, which might happen as a result of apoptosis ...

If you thought that mosquito control is only for residential spaces, youre mistaken. These days, hiring a mosquito treatment in Menomonee Fall for businesses is equally important. If your business is located in the forest area or near a water body, mosquitoes can be more frequent. Mosquito control offers relief to the customers and employees and ensures a healthy work environment. Here are a few reasons why your business needs mosquito control. To Ensure Safety Keeping your workforce healthy and safe from dangerous mosquito-related diseases is just one benefit. If your staff performs any unsafe tasks requiring focus, the mosquitoes can be a huge interruption. Imagine people operating or carrying loads when the mosquito starts frustrating them. For Enhancing Productivity. It can be challenging for employees to focus when mosquitoes are buzzing around and continuously biting. Besides, those bites can be very painful and can distract them from their work. Besides, switching between hitting ...

Specific gene candidates for shifts in insect seasonal timing have been difficult to accumulate via QTL mapping because of complex genetic bases or genomic architectures between populations (Tauber et al., 1977; Feder et al., 2002; Bradshaw et al., 2005; Mathias et al., 2007; Wadsworth et al., 2015). In such systems, transcriptome profiling can be a useful alternative to QTL mapping to nominate candidate genes. For example, in the pitcher-plant mosquito (Wyeomyia smithii), northern and southern populations differ in the critical day length required for diapause termination, but the genetic basis is complex, involving many loci and epistasis (Bradshaw et al., 2005; Mathias et al., 2007). Using microarrays, a total of 29 genes were nominated as candidates with one, a cuticular protein with cornea-specific expression, falling within a previously defined QTL for altered termination response (Emerson et al., 2010).. In European corn borers, early results implicated a major mendelian factor underlying ...

GLOBE Mosquito Larvae Protocol is a project for students, that may expand to adults and other volunteers, to learn how to identify mosquito larvae in their community or at a study site. Students will collect, sort, identify, and count the number of mosquito larvae they find in a sample of water. They can learn how to use a variety of sampling strategies depending on the types of mosquito larval habitats found in their particular study area. Through sampling, student volunteers can learn to identify mosquito larvae to either the genus or species level. By performing this kind of citizen science, young people can begin to understand the importance of representative sampling in scientific procedures, along with the relationship between species, climate, and mosquito-borne diseases. By collaborating with GLOBE through school, students can report their data online and share their observations and findings with real scientists ...

CRISPR gene drive has recently been proposed as a promising technology for population management, including in conservation genetics. The technique would consist in releasing genetically engineered individuals that are designed to rapidly propagate a desired mutation or transgene into wild populations. Potential applications in conservation biology include the control of invasive pest populations that threaten biodiversity (eradication and suppression drives), or the introduction of beneficial mutations in endangered populations (rescue drives). The propagation of a gene drive is affected by different factors that depend on the drive construct (e.g. its fitness effect and timing of expression) or on the target species (e.g. its mating system and population structure). We review potential applications of the different types of gene drives for conservation. We examine the challenges posed by the evolution of resistance to gene drives and review the various molecular and environmental risks associated with

Some diseases are transmitted to humans by mosquitoes. These disease often cycle back and forth from mosquito to human and back so that if an uninfected mosquito bites a human who is infected with one of these particular diseases, the mosquito can become infected themselves. After a certain period of time (e.g., a week), these […]

MOSQUITO CONTROL INFORMATION & FAQ What conditions warrant mosquito spraying and what conditions do not? The following conditions warrant mosquito spraying: Ambient temperature is at or above 50 degrees F. Wind speed is below 10 miles per hour. It is not raining. If any of these conditions are not met, spraying will not be done on that particular evening. Spraying will be done again on the next scheduled day. Where do you spray for mosquitoes? Our Mosquito Control Program manages areas within the Park County Mosquito District. Please reference the District Map in the left toolbar of this page for more information. What are you spraying? Our current program is primarily focused around Adulticide. Adulticide is insecticide that is specific to killing adult mosquitoes. SDS Sheet What is mosquito habitat? In general, ideal mosquito habitat is any location and/or artificial container that collects and holds shallow, standing water, typically for more than several days. This

Support your local community mosquito control programs. Mosquito control activities are most often handled at the local level, such as through county or city government. The type of mosquito control methods used by a program depends on the time of year, the type of mosquitoes to be controlled and the habitat structure. Methods can include elimination of mosquito larval habitats, application of insecticides to kill mosquito larvae or spraying insecticides from trucks or aircraft to kill adult mosquitoes. Your local mosquito control program can provide information about the type of products being used in your area. Check with your local health department for more information ...

JUAREZ-As health officials in Texas work to control West Nile virus, those along the border must keep an eye on another illness spread by mosquitoes-Dengue fever.. Preliminary testing in the border city Juarez indicates the presence of mosquitoes carrying Dengue fever.. The disease prevalent in parts of Mexico with a tropical climate but until now had not been seen this far north.. The mosquitoes caught in traps set out weekly in both El Paso and Juarez help officials identify which breeds of mosquitoes are in the area and if theyre carrying any diseases.. Remember some mosquitoes can travel up to a mile and some mosquitoes can travel up to five miles so theyll be able to cross that border pretty quick, said Danny Soto, code enforcement supervisor with the city of El Paso Environmental Services Department. http://www.khou.com/news/Mosquitoes-carrying-Dengue-Fever-spotted-futher-north-on-the-border-167389585.html. ...

Two general strategies can be considered for introducing transgenic mosquitoes in the field: population replacement or a genetic drive mechanism. Population replacement, or inundatory release, requires a significant reduction of the resident mosquito population (for instance, with insecticides), followed by the release of large numbers of refractory mosquitoes to fill the vacated biological niche. This strategy is promising as a research tool and as a field test to assess the effectiveness of the transgenic mosquito approach for interrupting malaria transmission. However, this strategy cannot be considered for large-scale control purposes, because it is not possible to produce sufficient numbers of mosquitoes to achieve population replacement on a country- or continent-wide level.. An efficient genetic drive mechanism is helpful because a manageable number of genetically modified mosquitoes can replace the wild population, even if the effector gene(s) imposes some fitness cost. A crucial ...

TY - JOUR. T1 - Analysis of the expression pattern of Mysidium columbiae wingless provides evidence for conserved mesodermal and retinal patterning processes among insects and crustaceans. AU - Duman-Scheel, Molly. AU - Pirkl, Nicole. AU - Patel, Nipam H.. PY - 2002/12/1. Y1 - 2002/12/1. N2 - The Wnt family includes a number of genes, such as wingless (wg), which encode secreted glycoproteins that function in numerous developmental patterning processes. In order to gain a better understanding of crustacean pattern formation, a wg orthologue was cloned from the malacostracan crustacean Mysidium columbiae (mysid), and the expression pattern of this gene was compared with that of Drosophila wg. Although Drosophila wg is expressed in many developing tissues, such as the ventral neuroectoderm, M. columbiae wg (mcowg) expression is detected within only a subset of these tissues. mcowg is expressed in the dorsal part of each developing segment and within the developing eye, but not within the ventral ...

COLUMBIA, S.C. - In observance of National Mosquito Control Awareness Week, the S.C. Department of Health and Environmental Control is reminding South Carolinians how to reduce their risk from the serious diseases mosquitoes can carry.. The week of June 24 is an opportunity for us to share valuable information with the public about the significance of mosquitoes in their daily lives and the important service provided by mosquito control workers throughout our state, said Sue Ferguson, an environmental health manager with DHECs Bureau of Environmental Health. Everyone can take part in local mosquito prevention and control efforts by doing some basic cleaning activities around their home.. Removing items from your yard that collect water, cleaning roof gutters and filling in low-lying areas will help prevent mosquitoes from breeding and allow outdoor activities such as gardening, barbecues and outdoor sports to be safer and more enjoyable, she said.. According to Ferguson, mosquito ...

Efforts underway to destroy potential mosquito breeding sites as the Cook Islands seeks to stay free of diseases such as dengue and zika

The emergence of mosquito-transmitted viruses poses a global threat to human health. Combining mechanistic epidemiological models based on temperature-trait relationships with climatological data is a powerful technique for environmental risk assessment. However, a limitation of this approach is that the local microclimates experienced by mosquitoes can differ substantially from macroclimate measurements, particularly in heterogeneous urban environments. To address this scaling mismatch, we modeled spatial variation in microclimate temperatures and the thermal potential for dengue transmission by Aedes albopictus across an urban-to-rural gradient in Athens-Clarke County GA. Microclimate data were collected across gradients of tree cover and impervious surface cover. We developed statistical models to predict daily minimum and maximum microclimate temperatures using coarse-resolution gridded macroclimate data (4000 m) and high-resolution land cover data (30 m). The resulting high-resolution ...

Mosquitoes can be carriers of pathogens dangerous to humans, pets, and wildlife. It may be against local regulations to cultivate mosquitoes, and please be responsible by draining any collection containers you will not be able to check regularly. To protect yourself against being bitten during collection wear clothing that covers as much bare skin as possible. Also note that mosquito pupae hatch into adult mosquitoes in about 2 days, it is therefore imperative that you make the collection of these a priority. Your fish will happily eat them ...

One of the most pressing policy issues of the modern era is how to improve public health in the worlds poorest regions. Of particular concern are those diseases spread by mosquitos: the World Health Organisation estimates a total of 96 million cases of dengue and, in 2017 alone, 219 million cases of malaria. Policies targeting such vector-borne diseases (VBDs) represent nothing new. However, there seems to be a continuing inability to move the agenda from one of disease reduction to eradication: clearly, current policy initiatives are not proving effective enough. This report aims to tackle this issue by outlining the problems associated with current policies and how they can be addressed through epidemiological innovation, with need to not only improve the efficacy of such policies, but also their cost-effectiveness and sustainability. Two innovative policies will be presented: that of manipulating the urban environment to reduce mosquito habitat and of harnessing predation pressure to better ...

ABSTRACT. Immature stages of Culicidae were collected in artificial containers in three conditions, between November 1997 and November 1998, in the rural area of São José dos Pinhais, Paraná, Brazil. Eight species were identified: Culex (Culex) eduardoi Casal & Garcia, 1968, Culex (Culex) acharistus Root, 1927, Culex (Culex) group coronator, Culex (Lutzia) bigoti Bellardi, 1962, Aedes (Protomacleaya) terrens (Walker, 1856), Limatus durhamii Theobald, 1901, Txorhynchites theobaldi (Dyar & Knab, 1906) and Phoniomyia sp. The Berger & Parker index was obtained for each condition and kind of container. These results were compared with those of Silva & Lozovei (1996) in the urban area of Curitiba. A greater number of species was observed in the rural area, with different dominance under each condition. The introduction of artificial containers can not show the number of Culicidae species that are present in an area, but it can indicate the species that show the greatest adaptability to ...

I think people should not be in panic, but in alert.. ...

The increase in molecular tools for the genetic engineering of insect pests and disease vectors, such as Anopheles mosquitoes that transmit malaria, has led to an unprecedented investigation of the genomic landscape of these organisms. The understanding of genome variability in wild mosquito populations is of primary importance for vector control strategies. This is particularly the case for gene drive systems, which look to introduce genetic traits into a population by targeting specific genomic regions. Gene drive targets with functional or structural constraints are highly desirable as they are less likely to tolerate mutations that prevent targeting by the gene drive and consequent failure of the technology.. ...

While historical evidence clearly suggests that vector control can be highly effective against mosquito-borne diseases [30-32], actual implementation of the strategy has not been optimal. Since a few years ago, there have been calls to restore the role of vector control by considering local evidence on disease ecology but also by developing new effective tools [7, 33]; as existing methods may not be adequate to achieve relevant targets [9-11].. It has previously been suggested that synthetic odor cues that attract or repel mosquitoes could form the basis of new technologies for future control of mosquito-borne diseases [10, 34], since these cues mediate important human-vector interactions that are associated with disease transmission [35]. For a long time, no chemical lure was known that could match or exceed attractiveness of natural human hosts, but recent research has led to one that is more attractive at long range than individual humans [19]. In their publication, the authors suggested a ...
