Full textAbstract:
People living in the tropical and subtropical regions of the world face an enormous health burden due to mosquito-borne diseases such as malaria, dengue fever, and filariasis. Historically and today, targeting mosquito vectors with, primarily, insecticide-based control strategies have been a key control strategy against major mosquito-borne diseases. However, the success to date of such approaches is under threat from multiple insecticide resistance mechanisms while vector control (VC) options are still limited. The situation therefore requires the development of innovative control measures against major mosquito-borne diseases. Transinfecting mosquitos with symbiotic bacteria that can compete with targeted pathogens or manipulate host biology to reduce their vectorial capacity are a promising and innovative biological control approach. In this review, we discuss the current state of knowledge about the association between mosquitoes andWolbachia, emphasizing the limitations of different mosquito control strategies and the use of mosquitoes’ commensal microbiota as innovative approaches to control mosquito-borne diseases.

In Pakistan, water storage bodies are often the most plentiful and active habitats of immature stages of mosquitoes. Mosquitoes are blood feeding type of vectors that bite a particular host and suck blood. As a result, these vectors transmit disease causing agents to the host system. The most common mosquitoes borne viral diseases in Pakistan are Chicken gunya, Dengue fever, west nile and Zika fever. These diseases are common in low and poor living standard areas. Death rate increases due to more attack of these fatal diseases. Mosquitoes breeding sites are water bodies, discarded tyres, water tanks, bottles, cups and ant traps. Various environmental agents i.e. temperature fluctuations and water resources, now increase the rate of mosquitos in most areas of Pakistan. There is a lack of basic medical education and knowledge about its pervention techniques in mosquito affected areas in Pakistan. The purpose of this review is to highlight the current status of emerging mosquito borne viral diseases in Pakistan, i.e. Chicken gunya, Dengue fever, est nile and Zika fever. There is more need of prevention strategies and understanding about factors involved in spreading of mosquito borne diseases.

Mosquitoes are important vectors of disease and require sources of carbohydrates for reproduction and survival. Unlike host-related behaviors of mosquitoes, comparatively less is understood about the mechanisms involved in nectar-feeding decisions, or how this sensory information is processed in the mosquito brain. Here we show thatAedesspp. mosquitoes, includingAedes aegypti, are effective pollinators of thePlatanthera obtusataorchid, and demonstrate this mutualism is mediated by the orchid’s scent and the balance of excitation and inhibition in the mosquito’s antennal lobe (AL). TheP. obtusataorchid emits an attractive, nonanal-rich scent, whereas relatedPlatantheraspecies—not visited by mosquitoes—emit scents dominated by lilac aldehyde. Calcium imaging experiments in the mosquito AL revealed that nonanal and lilac aldehyde each respectively activate the LC2 and AM2 glomerulus, and remarkably, the AM2 glomerulus is also sensitive to N,N-diethyl-meta-toluamide (DEET), a mosquito repellent. Lateral inhibition between these 2 glomeruli reflects the level of attraction to the orchid scents. Whereas the enriched nonanal scent ofP. obtusataactivates the LC2 and suppresses AM2, the high level of lilac aldehyde in the other orchid scents inverts this pattern of glomerular activity, and behavioral attraction is lost. These results demonstrate the ecological importance of mosquitoes beyond operating as disease vectors and open the door toward understanding the neural basis of mosquito nectar-seeking behaviors.

Background: Lymphatic Filariasis (LF), a mosquito born tropical parasitic disease, caused by Wuchereria bancrofti is not only a health but also a socio-economic problem in Bangladesh. Culex quinquefasciatus is the confirmed filarial vector in Bangladesh, so by controlling of this vector population, we can prevent this disease. To control this vector and decrease incidence of filariasis, we need to know studied mosquito’s sample in endemic areas.
Aim and objectives: Aim of this study was to see mosquito population in search of vector species in the endemic zones of malaria and filarial. Then we confirmed presence of vector species at molecular level by species specific DNA fingerprinting.
Methods: This cross-sectional entomological study was carried out in Hobiganj (Shatchori tea garden) and Moulvibazar district (Patrokhola and Madonmohonpur tea gardens). Mosquito was collected by paper cup with net, aspirator and torch light and vector mosquitoes were identified with stereoscopic microscope. After identification of the mosquitoes, these were stored in laboratory for analysis of the density of the vector mosquitoes in the endemic areas. Then the vector mosquitoes were identified through molecular method named Polymerase Chain Reaction (PCR).
Result: 1427 female mosquitoes belonging to 28 species under 5 genera were collected from three tea gardens. Culex quinquefasciatus which is the confirmed filarial vector in Bangladesh was found high in number (20.74%) out of the total collected mosquitoes. Other mosquito’s species were found in various ratios. Then Culex quinquefasciatus vector was identified by PCR.
Conclusion: As vector mosquitoes of LF are available in these tea gardens, the study concludes that these areas are highly LF endemic areas of Bangladesh. Through molecular method, the vector of LF can be identified certainly. As we identify the vector mosquito, thus we can prevent this LF disease at very early stage. So, these findings will be very beneficial and cost effective for a developing country like Bangladesh.

Mosquitoes are animals that are very often found in everyday life. Starting from the home environment, to the school environment. Mosquitoes are also animals that can carry various diseases. The FMIPA UNY Biology Garden Laboratory is overgrown with trees and there is a pool of water from several ponds that are deliberately made. That is what makes mosquitoes like the environment that is included in their habitat. At the UNY Biology Garden Laboratory, which is one of the student learning locations, mosquitoes are found flying and sometimes disrupting learning activities because they can stab and cause itching. The disturbance is feared to cause mosquito-borne diseases in students who are active in biology gardens. So that mosquito traps are made that are modified and adapted to the needs and location of the target. The tool made is a simple mosquito trap that utilizes a pool of water from a fish pond and a net from mesh or paranet cloth. The target place is the FMIPA UNY Biology Garden Laboratory, especially the pool area. While the target is the larvae or seeds of mosquitoes left by the mother. It is expected that the mosquitoes will perch on the paranet to lay eggs, then the eggs will fall down and will be eaten by fish. This is in addition to reducing the growth of mosquitoes, it can also be used for alternative food for fish, which can reduce spending to buy fish feed. Key words: mosquitos, trap

Dengue hemorrhagic fever is a global public health problem that caused an Arbovirus. Mataram city was a high infected area in West Nusa Tenggara Province, which included six sub-districts. The objective of this study is monitoring and controling dengue virus vectors based on temporal patterns using mosquitoTRAP. This research was explanatory in the cross-section design in 102 households (indoor and outdoor) as an observation site. Based on mosquito collection in October 2018 until March 2019, the amount reached 2,396 mosquitos such as Aedes albopictus (41%) and Aedes aegypti (59%). The mosquitos collection based on observation site showed no significant difference number (P=0.863). However, the number of mosquitos in temporal pattern showed significant difference number of first, middle, and end rain season (P = 0.001). Mosquitoes population at rain season had shown an increase until March 2019. Therefore, monitoring and controlling Aedes mosquitoes is crucial for prevention of dengue hemorrhagic fever case.

Full textAbstract:
The mouthparts of female mosquitoes have evolved to form a special proboscis, a natural biomicroelectromechanical system, which is used for painlessly penetrating human skin and sucking blood. The structure of the mosquito fascicle is observed using a scanning electron microscope, and the mechanical property of the labrum and maxillae, two of the most important parts of the mosquito’s fascicle is studied. The micronano structure and the special biomaterials of the mosquito’s proboscis make the mosquito penetrate easily into human skin with a surprising low force, which is measured to be only tens of micro-Newton. Our obtained results are helpful for the optimum design of the microneedles and transdermal drug delivery system.

Les malalties transmeses per vectors representen un alt percentatge de les malalties infeccioses en el món. Concretament, les malalties causades per arbovirus (arthropod-born viruses), que circulen en la naturalesa entre artròpodes (els seus vectors), i els hostes vertebrats (els seus reservorios), poden causar malalties greus en els hostes vertebrats, però no causen una patologia significativa en els vectors. Durant dècades les malalties causades per arbovirus van ser oblidades, ja que en la seva gran majoria estaven localitzades en zones en vies de desenvolupament. En l'actualitat, factors ambientals, ecològics i socioeconòmics, com el canvi climàtic i la globalització, han contribuït a l'emergència i reemergencia de les malalties arbovirales. El constant moviment de persones i mercaderies ha donat lloc a la colonització i establiment d'espècies d'exòtiques al nostre país, com el mosquit tigre (Aedes albopictus), el qual és transmissor de molts arbovirus (e.g. el virus del dengue, el virus Zika (ZIKV) o el virus chikungunya). El desenvolupament d'aquesta tesi es va centrar en realitzar estudis de competència vectorial per al ZIKV i en un estudi del transcriptoma de Culex pipiens després de ser exposat al phlebovirus de la febre de la Vall del Rift (RVFV) per a comprendre les interaccions el virus i els mosquits locals.
Els capítols I i II es van focalitzar a estimar la competència vectorial per a ZIKV de diferents espècies de mosquits de camp presents al nostre país: Aedes albopictus, Aedes caspius i Culex pipiens. A més, es van desenvolupar experiments de transmissió vertical per a determinar si la generació de mosquits provinents de femelles infectades amb el ZIKV és capaç de disseminar-ho. Durant el desenvolupament d'aquests estudis, s'ha demostrat que els mosquits locals de l'espècie Ae. albopictus són vectors competents per al ZIKV. No obstant això, les espècies Cx. pipiens i Ae. caspius són refractàries per a aquest arbovirus. Respecte a l'experiment de transmissió vertical, es va demostrar que la progènie de les femelles inoculades amb el virus de manera intratoràcica va ser susceptible a la infecció del virus, però no van ser capaços de disseminar-lo.
D'altra banda, el capítol III es va centrar en l'estudi de les interaccions a nivell molecular entre l'espècie de mosquit Cx. pipiens i RVFV, amb l'objectiu caracteritzar les alteracions a nivell molecular de l'expressió dels gens corresponents al sistema immune del mosquit durant la infecció per RVFV mitjançant una anàlisi del transcriptoma de novo. Com a resultat, es van obtenir 48 gens diferencialment expressats en els mosquits davant la presència del virus que servir de diana per a controlar la infecció, ja sigui per a desequilibrar la tolerància dels mosquits al virus com per a inhibir la infecció en els mosquits. Els resultats obtinguts de l'estudi de les alteracions del transcriptoma de mosquits de l'espècie Cx. pipiens exposats a RVFV estableixen les bases per a la realització de futurs estudis funcionals dels gens involucrats a controlar/permetre la infecció per RVFV.

Vector-borne diseases represent a 17 % of infectious diseases in the world. Among them, those diseases caused by arboviruses (arthropod-borne viruses), which circulate in the nature between arthropods (their vectors) and vertebrate hosts (their reservoirs), are currently provoking serious diseases in humans and animals. For decades, the arboviral diseases were neglected, since most of them were located in developing areas. Nowadays, environmental, ecological and socioeconomic factors (e.g., globalization and climate change) have contributed to the emergence and re-emergence of arboviral diseases. The constant movement of people and merchandise has allowed the colonization and establishment of exotic mosquito species in our country such as the tiger mosquito (Aedes albopictus), which is a potential vector of many arboviruses (e.g., dengue virus, Zika virus or chikungunya virus). This thesis focused on conducting vector competence and transmission studies in local mosquito species for Zika virus (ZIKV) and on the study of the Culex pipiens transcriptome alteration after being exposed to the Rift Valley fever phlebovirus (RVFV) in order to better understand how virus-vector interaction influences on ZIKV and RVFV transmission. Chapters I and II focused on estimating the vector competence for ZIKV of different field-collected mosquito species present in our country: Aedes albopictus, Aedes caspius and Culex pipiens. In addition, vertical transmission studies were performed to determine if the progeny of females infected with ZIKV were able to disseminate the virus. The results of these studies showed that local populations of Ae. albopictus were competent vectors for ZIKV and Cx. pipiens and Ae. caspius species were refractory for this arbovirus. Moreover, it was demonstrated that ZIKV was able to be transmitted to the progeny but the later could not disseminate the virus. Chapter III focused on the study of interactions between the Cx. pipiens mosquito species and RVFV at molecular level, with the aim to characterize the alterations in the expression of the mosquito genes related to the immune system during RVFV infection by analyzing de novo transcriptome. As a result, 48 immune differentially expressed genes in mosquitoes exposed to RVFV were altered, which could serve as potential targets to control the infection, either by unbalancing the mosquito tolerance to RVFV or by inhibiting the infection in mosquitoes. The results obtained on the Cx. pipiens transcriptome alterations due to exposure to RVFV pave the way for future functional studies about genes involved in the control/tolerance of RVFV infection. Overall, this thesis increased the knowledge to better design efficient strategies for ZIKV and RVFV surveillance and control.

Full textAbstract:
Els mosquits del gènere Culicoides actuen com a vectors de malalties importants que afecten tant a humans com a animals domèstics i salvatges. Al llarg de la última dècada aquests mosquits han tingut un paper molt important en l’epidemiologia de la major epizoòtia de Llengua Blava mai detectada a Europa, havent obligat a vacunar a milions de caps de bestiar per evitar les devastadores conseqüències que aquesta malaltia (de declaració obligatòria per la OIE) és capaç de provocar. Recentment, algunes espècies de Culicoides que pertanyen als subgèneres Avaritia i Culicoides han estat descrites com a potencials vectors de la malaltia de la Llengua Blava. En ambdós subgèneres es troben grups o complexes d’espècies que són difícils de diferenciar a nivell morfològic. Òbviament, una identificació correcta i precisa dels vectors resulta fonamental en la vigilància i control de malalties transmeses per artròpodes ja que es poden trobar diferències importants en la capacitat vectorial de les mateixes, inclús entre espècies properes.
Per aquesta raó, al llarg del transcurs d’aquesta tesi doctoral s’ha procedit a identificar la presència de grups d’espècies críptiques en els subgèneres Avaritia i Culicoides, tant aquells descrits amb anterioritat com aquells no descrits, i detectar el nombre d’espècies que conformen cada un dels grups a Catalunya. S’ha identificat un total de quatre grups d’espècies
críptiques, un en el subgènere Avaritia, l’anomenat grup Obsoletus, i tres en el subgènere Culicoides, els grups Pulicaris, Fagineus i Newsteadi. A continuació s’ha avaluat la validesa dels diferents caràcters morfològics diagnòstics descrits per identificar a les diferents espècies que formen part dels grups d’espècies críptiques en ambdós subgèneres i s’ha contrastat amb els resultats moleculars obtinguts a partir de la seqüenciació d’una regió d’ADN mitocondrial, concretament la subunitat I del gen Citocrom Oxidasa. En ambdós subgèneres ha estat possible detectar que alguns dels caràcters àmpliament utilitzats en la identificació de Culicoides resultaven ser erronis o bé no tenien el nivell de resolució per detectar espècies individuals en certs grups d’espècies. Per aquest motiu s’ha dissenyat i validat una bateria d’oligonucleòtids amb finalitats diagnòstiques que han permès identificar fins a 13 espècies de Culicoides que formaven part de grups d’espècies críptiques. Finalment per facilitar el diagnòstic laboratorial, s’ha dissenyat i validat diferents tipus de PCRs, one tube heminested PCR i multiplex PCR que han permès identificar, en una reacció individual, totes les espècies dins d’un mateix grup prèviament classificades com espècies críptiques.Biting midges of the genus Culicoides act as vectors for important diseases affecting humans and both wild and domestic animals. In the last decade these midges have played an important role in the epidemiology of the major bluetongue epizootics ever recorded in Europe, forcing several EU countries to perform a mass vaccination campaign for domestic ruminants to avoid the devastating consequences that this disease (being its declaration mandatory for OIE) is able to cause. Recently, some species of Culicoides midges belonging to the subgenus Avaritia and Culicoides have been described as potential vectors for Bluetongue disease. Within both subgenera there are groups or complexes of species which are difficult to distinguish morphologically. Obviously, a correct and precise identification of arthropod vectors is essential for the surveillance and control of arthropod borne diseases, as important differences in the vectorial capacity of these species can be detected, even between closely related species. For this reason, the first part of the dissertation focussed on the detection of cryptic species within the subgenus Avaritia and Culicoides, identifying those species already described as other new species with no previous description. Finally the number of species forming each of the groups in Catalonia was studied. A total of four groups with cryptic species was detected, one in the subgenus Avaritia, named Obsoletus group, and three in the subgenus Culicoides, named Pulicaris, Fagineus and Newsteadi groups. Then, several morphological characters already described and currently in use for diagnostic purposes were assessed for their validity to identify the species present within those groups of cryptic species detected in both subgenera. The results obtained for morphological characters were compared with molecular results obtained by sequencing a region in the mitochondrial DNA, the subunit I of the gene cytochrome oxidase (COI). Within both subgenera, it was possible to detect some of the characters widely used for routine Culicoides species identification were not valid diagnostic characters in fact, as they were just not diagnostic or they did not have the necessary resolution level to detect and distinguish individual species within certain groups of species. Thus, a group of oligonucleotides with diagnostic purposes were designed and validated through a battery of single PCRs. These oligonucleotides can be used to properly detect and identify each of the thirteen species of Culicoides which were part of the detected groups of cryptic species. Finally, to facilitate the laboratorial diagnostic assay, different types of PCR were designed and validated, one tube heminested PCR and three multiplex PCRs. Each of these diagnostic PCR assays allowed to identify, in an individual PCR reaction, all the species detected within a specific group previously classified as cryptic species.

Full textAbstract:
Malaria occurs mostly in the tropical regions of the world. Sub-Saharan Africa is the area most affected. The occurrence of a very efficient mosquito vectors Anopheles gambiae complex and Anopheles funestus group sustain high transmission of the Plasmodium falciparum, the most predominant and deadly malaria parasite species. Local weather conditions are appropriate and often transmission occurs throughout the year. Limited resources and socio-economic instability constitute the major factors impeding efficient malaria control activities.
The worldwide malaria eradication programme carried out during the 1950's focused mainly on insecticide residual spraying with DDT, anti-malarial drug treatment, and surveillance.
Regional eradication of the disease was achieved, nevertheless, in many endemic regions of sub-Saharan Africa excluded from the eradication campaign, the disease is still afflicting their inhabitants.
The malaria disease burden estimation in tropical Africa relies on mortality and morbidity data collected by the health system information.
Conservative estimates of the burden of disease claim for more than 300 million clinical episodes and 1 - 3 million deaths every year and young children harbour the largest and most important portion of this bulk.
Currently, the situation is deteriorating, increasing malaria-related morbidity and mortality have been reported. The rapid development and widespread of parasites strains resistant to almost all anti-malarial drugs, and vector resistance are the major contributing factors.
In addition, global climate change is affecting the health of human populations, including changes in the transmission and seasonality of vector-borne diseases. The range of factors affecting transmission and distribution of vector-borne diseases, particularly malaria, include those related to temperature, humidity and precipitation.
In Mozambique, malaria is endemic throughout the country, due to a multitude of factors such as climatic/environmental (favourable temperatures and rain patterns, abundant breeding sites) and socio-economical (poverty related improper housing/shelter, unaffordable preventive means). Transmission is perennial, with peaks during and after rainy seasons. The intensities of transmission may vary depending on the amount of rain and air temperature. However, at present there is a lack of good quality and updated information on the endemicity levels in the country.
The country-wide malaria survey carried out between 2002 and 2003 aimed to determine the prevalence and intensity of Plasmodium infections, the prevalence and the severity of anaemia in children under 10 years of age and in pregnant women across different ecological settings, in order to characterize the malaria transmission intensities and to estimate the disease burden in Mozambique.
The last comprehensive malaria survey in the country was carried out in 1952. For that reason, this survey was an unique opportunity to perform a sound methodological assessment of the current epidemiological malaria situation in the country.
Based on altitude and on geographical region differences samples were collected from stratified areas distinguished as coastal, plateau and highland strata, in the northern, centre-northern, central and southern regions. For sampling at community level, in each of those stratified areas, a modified cluster sampling method with 30 clusters, used by WHO for evaluation of coverage of the Expanded Programme of Immunization was adopted.
The study consisted of house-to-house survey, in 24 districts randomly selected. A total of 12,002 subjects including children less than ten years of age and pregnant women were enrolled. The malariometric survey consisted of finger pricking and blood collection to prepare thick and thin film for malaria parasite species identification, and respective density and determination of haemoglobin concentration. Measurement of axillary temperature and in those with fever a rapid enzyme test for malaria diagnosis was performed.
The entomologic survey consisted of pyrethrum spray knock down mosquito collections. In total 6,557 female anopheline mosquitoes caught in 1,440 dwellings, were analysed for sporozoite infection using PCR techniques and the entomological inoculation rates were determined for each strata across regions.
La malaria se encuentra preferentemente en las regiones tropicales del mundo, siendo África sub-sahariana el área con más afectación. La gran eficiencia de los mosquitos vectores Anopheles gambiae complex y Anopheles funestus favorece una gran transmisión del Plasmodium falciparum, el parásito más predominante y más maligno de las especies causante de malaria. Las condiciones ambientales locales son apropiadas y a menudo la transmisión se da a lo largo todo el año.
Los recursos limitados y la inestabilidad socio-económica constituyen los principales factores que impiden la total eficacia de las estrategias de control de la malaria.
El programa de erradicación mundial de la malaria se se llevó a cabo durante los años 50 focalizándose básicamente en la fumigación con DDT, el tratamiento con fármacos anti-maláricos y la vigilancia.
La erradicación regional de la enfermedad se conseguió en muchas regiones endémicas del África sub-sahariana, no obstante en zonas excluidas de la campaña de erradicación, la enfermedad continua afectando a sus habitantes.
La estimación de la carga de enfermedad por malaria en el África tropical se obtiene de los datos de mortalidad y morbilidad recogidos por el sistema de informació de la salud.
Los datos conservadores estiman que la carga de esta enfermedad causa más de 300 millones de episodios clínicos y entre 1 - 3 millones de muertes cada año, siendo los niños los más afectados.
En la actualidad, la situación se esta deteriorando, observándose un incremento de la morbilidad y mortalidad por malaria. El rápido desarrollo, la propagación de cepas del parásito resistentes ante todos los fármacos anti-maláricos y la presencia de vectores resistentes son los factores que más han contribuido a este incremento.
A demás, el cambio climático global está afectando la salud de las poblaciones, incluyendo cambios en la transmision y estacionalidad de las enfermedades mediadas por vectores. Los factores que afectan la transmisión y la distribución de este tipo de enfermedades, particularmente la malaria, incluyen los relacionados con la temperatura, la humedad y las precipitaciones.
En Mozambique, la malaria es una enfermedad endémica en todo el país, debido a la multitud de factores, como los climáticos/medioambientales (temperaturas favorables y patrones de precipitación, abundantes espacios para la reproducción) y socio-económicos (pobreza relacionada con vivienda inadecuada, medios preventivos inasequibles). La transmisión es perenne, con picos durante y después de la estación de lluvias. Las intensidades de transmisión pueden variar dependiento de la cantidad de precipitación y la temperatura en el ambiente. Sin embargo, actualmente, hay una falta de información actualizada y de calidad sobre los niveles de endemicidad del país.
El estudio llevado acabo por todo el país entre los años 2002 y 2003 tenía como objetivo determinar la prevalencia y la intensidad de las infecciones por Plasmodium, la prevalencia y la severidad de la malaria en niños menores de 10 años de edad y en mujeres embarazadas a través de diferentes nichos ecológicos, para poder caracterizar la intensidad de transmisión por malaria y estimar la carga de esta enfermedad en Mozambique.
El último estudio exahustivo de estas características en el país fue realizado en 1952. Por esta razón, este estudio era una oportunidad única para realizar un asesoramiento metodológico profundo de la situación epidemiológica actual de la malaria el país. Las muestras fueron recogidas basándose en la altitud y diferencias geográfica de cada región. Las areas estratificadas se clasificaron en: estrato costero, plateau y de montaña, y según la región en: norte, centro-norte, central y sur. Para el muestreo a nivel de comunidad, en cada una de esas áreas estratificadas, se utilizó un método por muestreo modificado por grupos con 30 grupos, ya usado por la OMS para la evalución de la cobertura del Programa Ampliado de Vacunación.
El estudio consisitió en visitar casa por casa en 24 distritos seleccionados aleatóriamente. Se incluyeron un total de 12,002 individuos, tanto niños menores de 10 años de edad como mujeres embarazadas. El estudio malariométrico consistió en recoger sangre por punción en el dedo para preparar una lámina delgada y otra gruesa para la identificación de la especie del parásito de la malaria y una estimación de la densidad, y para la determinación de la concentración de hemoglobina. Se tomó la tempreatura axilar y en presencia de fiebre se realizaba un test enzimático rápido para el diagnóstico de malaria.
El estudio entomológico consistió en la recogida de mosquitos rociados con piretrum. En total 6,557 mosquitos anófeles hembra de 1,440 viviendas fueron analizados para infeción de esporozoito usando técnicas de PCR, y la tasa de inoculación entomológica fue determinada para cada estrato a través de las diferentes regiones.

Full textAbstract:
Long-term insect abundances have been studied to investigate factors structuring the insect communities of the temporary wetlands around the River Dalälven floodplain. In the wet meadows and swamps in the River Dalälven floodplains recurrent floods are the ultimate prerequisite for high production of floodwater mosquitoes. In the larval stages these make up a superabundant potential prey for aquatic predatory insects while as adults they become nuisance for people and animals. Mosquito control with Bacillus thuringiensis israelensis (Bti) has been carried out in parts of the floodplain wetlands since 2002. This study investigate potential long-term effects of Bti on non-target insects in general, and non-biting midges (Diptera: Chironomidae) and aquatic predator insects in special in 10 temporary wetlands. Diving-beetles (Coleoptera: Dytiscidae) were the most common aquatic predatory insects in temporary flooded wetlands, and we found no indications that diving-beetles were negatively affected by mosquito larvae reduction with Bti-treatments. Non-target Bti-effects on the insect community in general, measured as increase or decrease of insect abundances, in general showed no effects of Bti except for Coleoptera. The non-biting midges were studied on species level, since this taxon previously has been associated with negative Bti non-target effects in the short-term. We found no reduced production of chironomids at neither family, nor subfamily level in Bti-treated as compared to untreated wetlands. We conclude that other factors than the occasional Bti-treatments dominate in structuring the chironomids fauna. For example, hydrology measured as floods and hydroperiod had substantial impact on insect emergence Increased hydroperiod was associated with lower insect emergence for the majority of the studied taxa, indicating an insect fauna adapted more to terrestrial conditions. In the final study, we developed and applied a molecular method to study interspecific predator – prey relationships between medium-sized diving beetles and floodwater mosquito larvae. Gut content analyses showed that floodwater mosquito larvae are a regular, but limited, part of the diet of medium-sized diving beetles. This thesis is one of the first long-term studies of insects of temporary wetlands in relation to mosquito control actions. The results indicate that hydrology is one of the major factors influencing and structuring the insect communities of the temporary flooded wetlands in the River Dalälven floodplains, and that mosquito control actions with Bti only have marginal effect on insect abundances.

Full textAbstract:
Aedes mosquitoes are responsible for the transmission of several arboviruses throughout tropical and subtropical regions of the world. In the Americas, Aedes aegypti is the most competent vector of dengue, chikungunya, Zika, and yellow fever. With up to 400 million cases globally each year, dengue fever is the fastest growing vector-borne disease in the world, and it has become an increasingly significant risk to global health. In the Western Hemisphere, dengue, and more recently chikungunya and Zika, exists throughout much of Latin America and the Caribbean. Both diseases are spread via Aedes mosquitoes and both constitute major health risks in Costa Rica. A dengue outbreak in Costa Rica in 2013 was the largest epidemic in the country since the return of the disease in 1993. Moreover, between 2014 and 2015 there was a 54.9% increase in dengue cases in Costa Rica, further demonstrating the relevancy of research on mosquito-borne diseases. Given this context, this study employs qualitative methods to critically investigate measures to combat Aedes mosquito-borne diseases in Costa Rica. Data were collected using household interviews (n = 80); semi-structured key informant interviews with public health officials, researchers, nonprofit organizations, and community leaders (n = 22); and a focus group discussion in each of two study areas. The results provide broad and place-specific information about mosquito control efforts and other actions deployed in Costa Rica to mitigate mosquito-borne diseases. The data reveal differences in perceptions and disease incidence among household interviewees as well as where households source information about mosquitoes and mosquito-borne diseases. Varying degrees of knowledge on mosquitoes and mosquito-borne diseases were uncovered across the study sites, as were differing attitudes among the general population regarding mosquito control techniques (e.g., fumigation, education campaigns, and household visits by public health officials). Additionally, data indicated a gap in knowledge regarding the ability of the public to report mosquito-related problems to health authorities. Households also exhibited discrepancies in knowledge pertaining to chikungunya transmission and details about the vector.Master of Science

O mosquito Aedes aegypti é o principal vetor das doenças Zika, Dengue, Chicungunha e Febre Amarela. Este artigo descreve a pesquisa em simulação computacional sobre o comportamento deste mosquito e sobre a eficácia de armadilhas em um certo cenário geográfico predefinido. A simulação computacional modela três aspectos fundamentais: (i) a reprodução dos mosquitos em focos, (ii) o crescimento da população de mosquitos, e (iii) o combate do vetor através de armadilhas. O objetivo principal desta simulação é a verificação dos locais mais adequados para a implantação de armadilhas com o propósito de combater os mosquitos, diminuindo as possibilidades de uma epidemia. Como resultado do trabalho foi desenvolvida uma ferramenta que contribui para o planejamento do combate ao vetor, melhorando a eficácia das ações de prevenção.

Full textAbstract:
Introdução: O mosquito Aedes aegypti é o principal vetor das arboviroses dengue, chikungunya, Zika e febre amarela. Para que ocorra a produção e a maturação de ovos, as fêmeas do mosquito realizam o repasto sanguíneo, quando ocorre a infecção e transmissão viral. A melhor maneira de evitar a propagação destas doenças é através do controle vetorial. Inseticidas químicos são utilizados no controle, entretanto, ao longo do tempo, os mosquitos adquirem resistência a esses compostos. Neste contexto, o RNA de interferência (RNAi) tem sido uma grande alternativa para o controle. Os genes de quitina sintase (CHSA e CHSB) são considerados excelentes alvos de silenciamento, pois, não são transcritos em vertebrados e plantas. Objetivos: Analisar os efeitos do silenciamento dos genes CHSA e CHSB na oviposição dos mosquitos tratados com dsRNACHS em baixas concentrações. Materiaisemétodos: A produção de dsRNA foi feita in vivo através da transformação de Escherichia coli, cepa HT115 com o plasmídeo L4440, contendo o inserto para a região do sítio catalítico de CHSA e CHSB e GFP (gene não-relacionado para mosquitos), usado como controle. Estas culturas foram lisadas com clorexidina 0,5%. O experimento foi feito em triplicata biológica, utilizando 10 larvas de 4° instar por grupo em 2 mL de água. Foi utilizado, em ambas condições, a concentração 2x10-5 µg/mL de células contendo dsRNACHS ou dsRNAGFP. Os mosquitos adultos sobreviventes foram alimentados com sangue de aves para testar a capacidade de oviposição e a viabilidade dos ovos postos. Resultados: As fêmeas adultas oriundas das larvas tratadas com dsRNACHS tiveram menor postura de ovos, e estes apresentaram fenótipo de ressecamento e deformidades, acarretando baixa eclosão, quando comparados com o controle. Conclusões: Concluímos que o dsRNACHS administrado afeta a produção e a qualidade dos ovos das fêmeas de Ae. aegypti, sendo uma boa estratégia de controle para este inseto.

Full textAbstract:
The detection of Aedes aegypti mosquito is essential in the prevention process of serious diseases such as dengue, yellow fever, chikungunya, and Zika virus. Common approaches consist of surveillance agents who need to enter residences to find and eliminate these outbreaks, but often they are unable to do this work due to the absence or resistance of the resident. This paper proposes an automatic system that uses aerial images obtained through a camera coupled from an Unmanned Aerial Vehicle (UAV) to identify rain gutters from a shed that may be mosquitoes’ foci. We use Digital Image Processing (DIP) techniques to differentiate the objects that may or may not be those foci of the mosquito-breeding. The experimental results show that the system is capable of automatically detecting the appropriately mosquito-breeding location.

Introdução: A expectativa pelo início do período chuvoso no Brasil, sempre traz o alerta para o aumento dos casos de dengue e outras doenças transmitidas pelo Aedes aegypti. Com a chegada das chuvas, a tendência é de que apareçam novos focos de mosquitos, ativando o ciclo deste mosquito que pode transmitir a dengue, zika e também a chikungunya. Objetivo: Em consonância com a disciplinas de ciências, educação física e português objetivou-se com este projeto abrir espaço, para que os adolescentes de 6º à 9º ano construíssem conhecimentos, valores, comportamentos e opiniões relacionadas ao problema recorrente enfrentado em várias regiões do Brasil e que são transmitidas pelo mosquito Aedes aegypti: a dengue, zika e chikungunya. Material e métodos: Na primeira fase do projeto, foi abordado nas aulas de Ciências o tema norteador: “Doenças transmitidas pelo Aedes aegypti: formas de contágio, tratamento, cura e prevenção”. Na segunda fase, foi elaborado com a ajuda da professora de português, um material informativo (confeccionado pelos estudantes) para que fosse distribuído nas ruas no dia da “Volta Olímpica”, idealizada pelo professor de educação física. Resultados: Cerca de 80 estudantes participaram da atividade. Nas ruas, os estudantes distribuíram a cartilha produzida por eles, sobre o mosquito Aedes aegypti; como fazer a sua identificação, bem como as doenças transmitidas por ele e sua devida prevenção; promovendo desta maneira, a conscientização dos participantes sobre a importância da contribuição de cada um da sociedade, no combate ao referido mosquito. Conclusão: Conclui-se que a iniciativa alcançou seu objetivo, uma vez que promoveu a integração das turmas de ensino fundamental II, com a comunidade no entorno da escola. Com esta atividade, foi possível ensinar aos alunos sobre o tema proposto e fazer com que os mesmos praticassem a corrente do bem: que é aprender sobre um conteúdo, e não o guardar para si, mas compartilhá-lo com o próximo. Através da Volta olímpica, os estudantes objetivaram influenciar o público externo que pôde compreender que, a dengue, zika e chikungunya são doenças sérias, e um grande problema de saúde pública em nosso país que, no entanto, pode ser evitado com devida prevenção.

A karyotypic analysis of three mosquito species Aedes excrucians, Ae. behningi and Ae. punctor (Diptera: Culicidae). Differences in the lengths of chromosomes, the distribution of C- and DAPI blocks of heterochromatin, and the localization of rDNA genes on chromosomes were revealed. Aedes excrucians has the largest chromosome length among the three species represented. Ae. punctor differs in the localization of rDNA on the second chromosome, while in Aedes excrucians and Ae. behningi, rDNA genes are located on chromosome 1. All three species have different C-banding and species-specific localization of heterochromatin DAPI blocks. Consequently, chromosome analysis can serve as an additional mechanism for species identification of mosquitoes of the genus Aedes.

Insects have a strong relationship with the human-beings. For example, some species of mosquito transmit diseases that kill millions of people around the world. At the same time, the presence of certain insects is essential for the ecological balance and food production. For this reason, we are developing a novel sensor as a tool to efficiently control disease vectors and agricultural pests without harming other species. In this paper, we demonstrate how we overtook the most important challenge to make this sensor practical: the creation of accurate classification systems. Despite the short duration and the very simple structure of the signal, we managed to successfully identify relevant features using speech and audio analysis techniques. We show that we can achieve an accuracy of 98% in the task of disease vector mosquitoes identification.
