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.

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.

The World Health Organization estimates that 1 billion cases of infectious disease originate from vector transmission, resulting in several million deaths annually. Mosquitos are the primary vector for multiple diseases in humans that cause self-limiting to sight-threatening ocular complications and significant systemic illness. The 2015-2016 outbreak of the mosquito-borne Zika virus in North and South America brought to the forefront how quickly mosquitoes can spread disease between continents, especially among vulnerable patient populations. Optometrists should be familiar with the associated ocular complications in order to effectively diagnose, co-manage, treat, and educate patients who have been infected by mosquito-borne disease. This paper reviews the ocular manifestations of mosquito-transmitted diseases including Zika virus, West Nile virus, Malaria, Dengue fever, Chikungunya, and Dirofilaria.

Mosquito control is important as mosquitoes are extremely harmful pests that spread various infectious diseases. In this research, we present the preliminary results of an automated system that detects the presence of mosquitoes via image processing using multiple deep learning networks. The Fully Convolutional Network (FCN) and neural network-based regression demonstrated an accuracy of 84%. Meanwhile, the single image classifier demonstrated an accuracy of only 52%. The overall processing time also decreased from 4.64 to 2.47 s compared to the conventional classifying network. After detection, a larvicide made from toxic protein crystals of the Bacillus thuringiensis serotype israelensis bacteria was injected into static water to stop the proliferation of mosquitoes. This system demonstrates a higher efficiency than hunting adult mosquitos while avoiding damage to other insects.

Full textAbstract:
Chikungunya virus (CHIKV) is transmitted by Aedes mosquitoes and causes prolonged arthralgia in patients. After crossing the mosquito midgut barrier, the virus disseminates to tissues including the head and salivary glands. To better understand the interaction between Aedes albopictus and CHIKV, we performed RNASeq analysis on pools of mosquito heads and parts of the thorax 8 days post infection, which identified 159 differentially expressed transcripts in infected mosquitos compared to uninfected controls. After validation using RT-qPCR (reverse transcriptase-quantitative polymerase chain reaction), inhibitor of Bruton’s tyrosine kinase (BTKi), which has previously been shown to be anti-inflammatory in mammals after viral infection, was further evaluated for its functional significance. Knockdown of BTKi using double-stranded RNA in a mosquito cell line showed no significant difference in viral RNA or infectivity titer. However, BTKi gene knocked-down cells showed increased apoptosis 24 hours post-infection compared with control cells, suggesting involvement of BTKi in the mosquito response to viral infection. Since BTK in mammals promotes an inflammatory response and has been shown to be involved in osteoclastogenesis, a hallmark of CHIKV pathogenesis, our results suggest a possible conserved mechanism at play between mosquitoes and mammals. Taken together, these results will add to our understanding of Aedes Albopictus interactions with CHIKV.

The mosquito’s innate immune system controls both Plasmodium and bacterial infections. We investigated the competitiveness of mosquitoes genetically modified to alter expression of their own anti-Plasmodium immune genes in a mixed-cage population with wild-type mosquitoes. We observed that genetically modified mosquitoes with increased immune activity in the midgut tissue did not have an observed fitness disadvantage and showed reduced microbial loads in both the midgut and reproductive organs. These changes result in a mating preference of genetically modified males for wild-type females, whereas wild-type males prefer genetically modified females. These changes foster the spread of the genetic modification in a mosquito cage population.

Full textAbstract:
Sterile insect technique (SIT) using irradiated mosquitoes is an effective control method capable of being assimilated into integrated vector management (IVM) programs. Chemical control of mosquitoes using ultra-low volume (ULV) spray applications of pyrethroid and organophosphate insecticides is already an essential component of IVM programs. Prior to their release in nature, irradiation of mosquitoes for SIT use can significantly impact the mosquito’s biology, specifically its host-seeking and feeding behavior. Little is known about how radiation exposure might impact a mosquito’s susceptibility to pyrethroid insecticides. The present study was carried out to evaluate the influence of Aqualuer ® 20-20 ULV applications on irradiated Aedes aegypti. Caged mosquito trials indicated that both male and female irradiated Ae. aegypti were as susceptible as their non-irradiated counterparts of the same population to Aqualuer 20-20 ULV application, with the highest mean percent mortalities achieved at the first 24h post-treatment period at both 30.5 m and 61 m downwind of the spray application path.

Full textAbstract:
Zika virus (ZIKV) is primarily transmitted to humans by Aedes aegypti and Ae. albopictus. Vector–virus interactions influencing vector competence vary and depend on biological and environmental factors. A mosquito’s chronological age may impact its immune response against virus infection. Insecticides, source reduction, and/or public education are currently the best defense against mosquitoes that transmit ZIKV. This study assessed the effects of a mosquito’s chronological age at time of infection on its response to ZIKV infection. We exposed young (6–7 d post-emergence) and old (11–12 d post-emergence) Ae. albopictus to a sublethal dose of bifenthrin prior to oral exposure to blood meals containing ZIKV (7-day incubation period). Old mosquitoes experienced a significantly (p < 0.01) higher rate of mortality than young mosquitoes. Significantly higher ZIKV body titers (p < 0.01) were observed in the old control group compared to the young control group. Significantly higher (p < 0.01) ZIKV dissemination rates and leg titers (p < 0.01) were observed in old bifenthrin-exposed mosquitoes compared to old control mosquitoes or young bifenthrin-exposed or control mosquitoes. Hence, bifenthrin exposure may increase the potential for virus transmission; however, the degree of these impacts varies with mosquito age. Impacts of insecticides should be considered in risk assessments of potential vector populations.

Introduction: Mosquitoes are potentially regarded as one of the most deadly animals in the world as they are known to vector a number of vital diseases. The faunistic composition and prevalence of these mosquitoes are dependent on the characteristics of the larvae habitats. Objective: In this study we surveyed the mosquito larvae in relation to the characteristics of their various microhabitats with the aim of determining how the habitats influence the composition, abundance and distribution of the mosquito larvae on Obafemi Awolowo University, Ile - Ife campus. Methods: We did mosquito larvae sampling monthly between 07: 00 and 10:00 for six months (August, 2017 - January, 2019) using standard dipping method. The various microhabitats sampled included; ground pools, discarded containers, drainage channels and tree holes in each of the study sites. Results: We identifies seven species distributed in three genera as following; Anopheles sp. (Anopheles gambiae, Anopheles funestus); Aedes sp. (Aedes aegypti, Aedes albopictus); Culex sp (Culex pipiens, Culex quinquefasciatus, Culex poicilipe). Culex was the dominant and most abundant genera as it accounted for 48% of the entire collection. Mosquito larvae were significantly (p<0,05) more abundant in the dry season than in the wet season. The highest abundance of mosquitoes was recorded in Akintola Hall as it accounted for 50,1% of the entire collection. Findings in this study also revealed that drainage channels in the study sites accounted for the highest abundance of mosquitos. A total of 277 ind. were collected in the various drainage channels in the study sites and this represented 45% of the entire collection while Leaking pipes and Ground pools accounted for 89 (15%) and 87 (14%) individuals respectively. We collected majority of the mosquitoes near dwellings thus suggesting that the species identified in this study have affinity for humans and their dwellings. Conclusion: We suggest that un-kept drainage channels, leakages and discarded domestic containers littered around the study sites are possible contributing factors to the enormous breeding sites available to mosquitoes. Elimination of such breeding sites can effectively mitigate the survival and prevalence of mosquitoes in the area.

O objetivo deste estudo foi determinar em laboratório se Aedes (Stegomyia) aegypti (L.), importante vetor da dengue e febre amarela, alimenta-se do néctar de Euphorbia milii Des Moul (Euphorbiaceae) , planta comumente utilizada nos domicílios como cerca viva, e avaliar o efeito desta alimentação em sua sobrevivência. O tempo de vida de ambos os sexos foi acompanhado diariamente e um teste de detecção de frutose foi utilizado para a comprovação da ingestão de açúcar pelos mosquitos. O acesso diário ao néctar conferiu um aumento significativo no tempo de vida de machos e fêmeas (12,8 e 18,4 dias, respectivamente), em relação aos mosquitos mantidos somente com água (6,4 e 7,4 dias, respectivamente). Plantas em ambientes domésticos, produtoras de néctar e adequadas à alimentação do mesmo pelos mosquitos, assim como E. milii, possuem o potencial de desempenhar um significativo papel no orçamento energético de mosquitos. Um aumento na sobrevivência de fêmeas pode significar um aumento na probabilidade de infecção e transmissão de agentes patogênicos e nos machos um aumento na probabilidade de inseminação das fêmeas. Ainda que frequentemente desconsiderada em pesquisas ou táticas de controle, a propensão do mosquito Ae. aegypti em ingerir açúcares pode ser uma variável que confira vantagens a este vetor.
Increases Survival of Aedes (Stegomyia) aegypti (Linnaeus) Under Laboratory Condition by the Ingestion Extrafloral Nectar of Euphorbia milii Des Moul. (Euphorbiaceae)
Abstract. The objective this study was to determine if in laboratory, Aedes (Stegomyia) aegypti (L.), an important vector of dengue and yellow fever, feeds on the nectar of Euphorbia milii Des Moul (Euphorbiaceae) , plant commonly used in homes as a hedge, and evaluate the effect of feeding on survival. The lifetime of both sexes was checked daily and a test for fructose was used for verification of sugar intake by mosquitoes. The daily access to the nectar gave a significant increase in the lifetime of males and females (12.8 and 18.4 days, respectively) in relation to mosquitoes maintained only with water (6.4 and 7.4 days, respectively). Plants in domestic environments, producing nectar and suitable for feeding by mosquitoes of the same, as well as E. milii, have the potential to play a significant role in the energy budget of mosquitoes. An increase in the survival of females can mean an increased likelihood of infection and disease transmission in males and an increased likelihood of insemination of females. Although often overlooked in research and control tactics, the propensity of the mosquito Ae. aegypti ingesting sugars can be a variable that confers advantages to this vector.

Although the mosquito vectors of malaria have an effective immune system capable of encapsulating many foreign particles, they rarely encapsulate malaria parasites in natural populations. A possible reason for this apparent paradox is that infection by malaria reduces the capability of the mosquito to mount an effective immune response. To investigate this possibility, we blood-fed Aedes aegypti mosquitoes on an uninfected chicken or on one infected with Plasmodium gallinaceum, and compared the proportions of the infected and uninfected mosquitoes that melanized a negatively charged Sephadex bead injected into the thorax 1, 2 and 4 days after blood-feeding. About 40% of the uninfected mosquitoes, but less than 25% of the infected ones, melanized the bead. The difference between infected and uninfected mosquitoes was most obvious 1 day after infection (at the parasite's ookinete stage), while the difference diminished during the early oocyst stage (2 days after infection) and disappeared at the later oocyst stage (4 days after infection). These results suggest that the parasite can either actively suppress its vector's immune response or that it modifies the blood of its chicken host in a way that reduces the efficacy of the mosquito's immune system. In either case, the reduction of immunocompetence can have important consequences for malaria control, in particular for the current effort being invested into the genetic manipulation of mosquitoes.

Mosquitoes are the most important single group of insects in terms of public health importance. Mosqui-toes not only cause nuisance by their bites but also transmit deadly diseases. The activity of mosquitoes is affected by climate, light and temperature. In tropical areas like India, the population of mosquitoes is found huge day by day. Repeated use of synthetic insecticides for mosquito control has disrupted environment as well as human health. To overcome this problem, plant derived compounds may be the better alternate over synthetic insecticides. To enhance the health and hygiene qualities by means of use of medicinal plants through effective application technique on textiles, marigold (petals) and nirgundi (leaves) methanol extract was used as mosquito repellent finish on 100 % woven cotton. For applying mosquito repellent finish on fabric, complex coacervation technique of microencapsulation was used through pad-dry-cure method. Finished cotton samples were tested against Anopheles stephensi by using laboratory cage method for their efficacy and durability to washing and sun-drying as per standard test methods. Marigold (petals)and nirgundi (leaves) extract finished fabric samples showed 96 and 94 % repellency respectively after 60 minutes of observation. It remained 56 % and 54 % (after 15 washes) and 54 and 52 % (after expo-sure in sun for 3 hours) by the application of marigold and nirgundi extracts respectively. Hence, microencapsulation technique on selected cotton textile proved effective to repel mosquitoes up to acceptable level according to WHO (1996).

Many RNA viruses have recently emerged, threatening humans and causing harm to animals and plants. Bunyaviruses represent one of the largest groups of RNA viruses and are able to infect a wide range of hosts (invertebrates, vertebrates, and plants). Recently, new insect-specific viruses have been isolated from mosquitoes and phlebotomine sandflies worldwide. Little is known regarding the impact of these viruses on the vector life cycles and the stages of oviposition, breeding, blood feeding, and the mosquito’s lifespan. This study describes, for the first time in South America, the detection and characterization of a recently discovered bunyavirus corresponding to the Wutai mosquito phasivirus, confirming its high prevalence in the Culex spp. and Aedes spp. mosquitoes collected in the urban environment of Rio de Janeiro city, Brazil. The knowledge of the mosquito’s insect-specific virus infection can improve virus evolution studies and may contribute to the understanding of intrinsic factors that influence vector competence to transmit pathogenic viruses.

Full textAbstract:
The first documented Rift Valley hemorrhagic fever outbreak in the Arabian Peninsula occurred in northwestern Yemen and southwestern Saudi Arabia from August 2000 to September 2001. This Rift Valley fever outbreak is unique because the virus was introduced into Arabia during or after the 1997–1998 East African outbreak and before August 2000, either by wind-blown infected mosquitos or by infected animals, both from East Africa. A wet period from August 2000 into 2001 resulted in a large number of amplification vector mosquitoes, these mosquitos fed on infected animals, and the outbreak occurred. More than 1,500 people were diagnosed with the disease, at least 215 died, and widespread losses of domestic animals were reported. Using a combination of satellite data products, including 2 x 2 m digital elevation images derived from commercial satellite data, we show rainfall and potential areas of inundation or water impoundment were favorable for the 2000 outbreak. However, favorable conditions for subsequent outbreaks were present in 2007 and 2013, and very favorable conditions were also present in 2016–2018. The lack of subsequent Rift Valley fever outbreaks in this area suggests that Rift Valley fever has not been established in mosquito species in Southwest Arabia, or that strict animal import inspection and quarantine procedures, medical and veterinary surveillance, and mosquito control efforts put in place in Saudi Arabia following the 2000 outbreak have been successful. Any area with Rift Valley fever amplification vector mosquitos present is a potential outbreak area unless strict animal import inspection and quarantine proceedures are in place.

Mosquitoes depend on blood meal for the development of their eggs into offsprings. By knowing the biting behaviour of mosquitoes, we may control mosquito-borne diseases and manage the mosquitoe menace successfully. The present study has been designed to study the biting behaviour of the filarial vector, Culex quinquefasciatus Say, in Madurai, Tamil Nadu, India from July to November 2006. This period was selected as mosquitoes are prevalent during this rainy season. Biting was more during September, October and November and the maximum of 28 caught/man/hour was recorded in November. It is predominantly an exophilic biter, but biting was also noticed as maximum inside the house during July in the study. The density of the biting population in the first floor was more than that of the second floor, which indicated the existence of vertical stratification in the biting behaviour of Cx quinquefasciatus.

Mosquitoes are insects that act as vectors of disease. Some of the diseases caused by mosquitoes are Dengue Hemorrhagic Fever (DHF), filariasis, Malaria, Chikungunya and Encephalitis. Cases of mosquito-borne diseases are always increasing and can cause death. The purpose of this study was to determine the ability of attractant (fermented cassava and sea shrimp immersion) in mosquito traps in controlling mosquitoes. The research method used a quasi-experimental method. This research was conducted in Buhung Bundang Village, Bontotiro District, Bulukumba Regency. The results showed that the addition of attractants had the ability to attract mosquitoes to land on the traps. Of the two attractants used, fermented cassava was the most preferred attractant for mosquitoes compared to shrimp immersion attractant. The number of mosquitoes caught in all mosquito traps was 62. The number of mosquitoes in the cassava fermentation attractant was 36, while the shrimp immersion attractant was 26. The conclusion of this study shows that mosquito traps with the addition of attractants from fermented cassava and sea shrimp immersion can be used in mosquito control.

Consider a SIR model for the spread of dengue hemorrhagic fever involving three populations, mosquito eggs, mosquitoes, and humans. The parameters of the SIR model were estimated using rainfall data and air temperature for the cities of Pekanbaru and Solok. The main aim of this paper is to determine the effect of mosquito larvae and adult mosquito control on the spread of the dengue virus. Numerical solutions were also presented by using the Runge-Kutta method of order 4. Based on the results, the SIR model was obtained by involving the control parameters of mosquito larvae and adult mosquitoes. Besides, the mosquito population is affected by changes in temperature, rainfall, and fog. Numerical simulations illustrate that the number of infected mosquitoes and infected humans is influenced by the parameters of the percentage of mortality of mosquito larvae and adult mosquitoes.

A method of quantitative elemental analysis of mosquitoes which convey serious infectious diseases, such as Japanese encephalitis and Dengue fever, has been developed in order to clarify their mode of life and sphere of action. The method was developed on the basis of a standard-free method for biological samples. The method enables us to perform quantitative analysis of untreated mosquito. Moreover, the method was successfully applied to quantitative analysis of each part of mosquito's body such as head and chest, abdomen, leg and wing. It was found that there are clear differences among parts in the body of mosquito, and also among different species such as Culex tritaeniorhynchus and Aedes albopictus. The method was successfully applied to quantitative analysis of small fly belonging to Sciaridae (Bradysia.praecox) whose size is smaller than that of mosquito. It was also confirmed that the method is applicable to other kind of bio-samples of small quantities such as a grain of egg of Alaska pollock whose dry weight is less than 100 μg.

Abstract. Japanese encephalitis is a mosquito-borne zoonotic disease that has pigs as the amplifying host. It is important to study the diversity of mosquito species around pig populations to determine the potential of Japanese encephalitis vectors in the region. This study is a cross-sectional study with a single sampling method for adult mosquitoes around pigpen in Tangerang Regency. The capture of adult mosquitoes is carried out by the outdoor resting mosquitoes collection at 18:00 - 24:00 using aspirators and light traps. Female mosquitoes were identified and subsequently tested RT-PCR for JEV. Catching results obtained 223 mosquitoes from the genus Culex, Armigeres, Aedes, Anopheles, and Mansonia with a total of 10 species. Species diversity in the pigpen area is classified as moderate (H = 1.0875 – 1.292) with Culex vishnui and Culex quinquefasciatus as the most abundant species. RT-PCR test found there’s no mosquito’s samples with positive JE RNA virus. Several species of mosquitoes found around pigpens in Tangerang District have the potential to become JEV vectors, so that control to the mosquito abundance and health of pigs is needed as a preventative measure.

Mosquitoes ( Culex pipiens L., 1758) are important vectors for diseases of both wildlife and humans. Understanding how natural factors influence mosquito abundance may provide insights into the ecology of various diseases, as well as solutions to controlling disease vectors. One of the natural factors regulating mosquito distributions and population sizes is predation. A poorly understood source of natural mosquito predation is amphibians. We determined the mosquito consumption capability of two amphibians, adult Red-spotted Newts ( Notophthalmus viridescens viridescens (Rafinesque, 1820)) and larval Mole Salamanders ( Ambystoma talpoideum (Holbrook, 1838)). We also compared mosquito consumption of eastern mosquitofish ( Gambusia holbrooki Girard, 1859), a known predator of mosquitoes, and A. talpoideum. Both salamander species were capable of consuming large numbers of mosquito larvae per day (least-square means ± 1 SE = 439 ± 20 and 316 ± 35 mosquitoes/day consumed by A. talpoideum and N. v. viridescens, respectively). In A. talpoideum, mosquito consumption scaled with body size, with the largest individual (4.4 g) ingesting 902 mosquitoes in 1 day. Gambusia holbrooki consumed 3.5× more mosquitoes during a 24 h feeding trial than similar-sized A. talpoideum. Our findings suggest that amphibians could have a substantial impact on mosquito larvae abundance, especially considering that amphibians can reach densities of up to 500 000 individuals/ha. Furthermore, we hypothesize that introduction of G. holbrooki could reduce abundances of native mosquito predators (e.g., salamanders) indirectly, through competition for invertebrate prey.

PurposeThe purpose of this paper is to understand people’s preferred design and functional features for mosquito-bite protective clothing.Design/methodology/approachTotal 348 participants were asked through an online survey about their perceptions and behaviors related to mosquito bite prevention, preferred design and functional features for clothing, preferred design and functional features for smart clothing, preferred types of transferred data, and their demographic backgrounds. A series oft-tests and analyses of variance were computed using IBM’s SPSS 24.0.FindingsThere were significant differences in functional and design preferences among participants (p<0.05~0.001). The results suggest developing mosquito protective clothing as long pants for married people and outerwear for younger groups (10-40s), long-sleeved tops for all, and using thick fabrics for younger people than those over the 50s. Designers can develop smart clothing that can repel mosquitos through scents and cover the body, or as smart watches or wristbands to protect against mosquito bites. The connected software can present data about the mosquito numbers around the user, distances between the user and mosquitos, and product status. Marketers can target parents who showed more willingness to use the mosquito-bite protective clothing than individuals without children.Originality/valueThe outcomes of the study will help designers when developing mosquito-bite protective clothing and ultimately decrease the rate of diseases transmitted by mosquitos.

Dengue virus (DENV), the pathogen that causes dengue fever, is mainly transmitted by Aedes aegypti. Surveillance of infected mosquitoes is a major component of integrated mosquito control methods for reducing the risk of vector-born disease outbreaks. However, a specialized rapid test for DENV detection in mosquitoes is not currently available. Utilizing immunoblotting, we found that the secretion of NS1 from both a DENV-infected mosquito cell line and mosquito bodies was below the detection threshold. However, when Triton X-100 was used to lyse infected mosquitoes, intracellular NS1 was released, and could then be effectively detected by the NS1 rapid test. The distribution of DENV NS1 in intrathoracically infected mosquitoes was different from that of orally infected mosquitoes. Next, we performed sensitivity tests by bisecting mosquitoes longitudinally; one half of each mosquito was subjected to the NS1 rapid test while the other half was used for qPCR confirmation. This modified test had a sensitivity of nearly 90% from five days post-infection onwards, while DENV had escaped from the midgut barrier. This adapted test offers a valuable, easy-to-use tool for mosquito surveillance, which is a crucial component of DENV disease control.

In Nigeria mosquito-borne diseases particularly malaria and some emerging and re-emerging infections such as Zika, dengue fever, yellow fever, constitute a big threat to public health. However, there is a paucity of information on the species of mosquito in Kano City Northern Nigeria. Despite mosquitoes control programs that had taken place in this state and its environment, mosquitoes remain a problem in the state and there is little information on the relationship between mosquito species and the effect of some climatic parameters on the mosquitoes distribution in the study area. The mosquito species were collected using the CDC light trap method and climatic parameters such as temperature and relative humidity were recorded at every one hour of the experiments. A total of 26,652 mosquitoes were collected from January to July 2018. Out of the 26,652, 17444 (65.46%) were Culex and 9208 (34.54%) were Anopheles mosquitoes. Culex species were observed to have its peak at 10:00 - 11:00 pm (5435) while Anopheles mosquito species were observed to attain their first peak at 3:00 – 4:00 am (3416). High collections of mosquitoes were obtained at optimum temperature and relative humidity. This study provided information on the mosquito species diversity in respect to seasonal and periodic variation at AKTH and the effect of some climatic parameters.

Vector-borne mosquito diseases are still as a public health problem in the world, including in Indonesia. Many of mosquitoes species are significantly as vectors of patogen, such as virus, bacteria, protozoan, and helminths due to human health. Samborejo Village is one of filariasis endemic areas and it is still in a high mf-rate. Each of mosquito species has a differential of distribution, bioactivities pattern, and type of habitat of their breeding sites with others. The objective of this study was to determine the diversity, dominancy, and periodicity pattern of mosquitoes during night time in Samborejo Village Tirto Distric Pekalongan Regency. Mosquitoes collections were done by landing method, from 6 pm - 6 am of in an hour period of collection, for biting and resting activities and also for indoor and outdoor collection respectively. Mosquitoes were then identified and the diversity was analized by Shannon-Wienner Index. The total number of each species was served in percent. Totally there were 339 collected mosquitoes, consisting of 165 (48.67%) females and 174 (51.33%) males. Of all, there were 4 species identified which were Culex quinquefasciatus (92.1%), Culex tritaeniorhynchus (0.6%), Culex vishnui (1.8%), and Aedes aegypti (5.5%). Samborejo Village showed in low diversity with the index of 0.338, and Cx. quinquefasciatus to be the dominant species in this area. Culex quinquefasciatus also became the frequent species in each period of collection for indoor and outdoor, and it showed the indoor active biting at 9 pm, 01 am, and 03 am; furthermore, the outdoor active biting was at midnight (00) and at 03 am. However, Aedes mosquitoe was showed active biting in earlier, it was at 6 pm, 7 pm, and at 02 am.

Full textAbstract:
The cosmopolitan insect-pathogenic fungus and popular biocontrol agent Beauveria bassiana can be used to control Anopheles mosquito populations and restrict the spread of malaria, the deadliest vector-borne infectious disease in the world caused by the protozoan parasite Plasmodium. Here, we establish that infection with a double-stranded (ds)RNA mycovirus, Beauveria bassiana polymycovirus (BbPmV)-1, significantly reduces B. bassiana virulence against A. coluzzii, the main vector of malaria. The BbPmV-1-mediated hypovirulence can be at least partially attributed to slow fungal growth on the mosquitos. Analysis of the dual next-generation sequencing of the B. bassiana and A. coluzzii transcriptomes provided insight into the molecular mechanisms of the BbPmV-1-mediated effects. BbPmV-1-free B. bassiana has a wide impact on the A. coluzzii transcriptome, affecting immunity and metabolism, and led to the identification of novel immune response proteins. BbPmV-1 regulates the gene expression profile of its fungal host, directing the use of available resources towards sporulation and suppressing the mosquito immune system. Additionally, BbPmV-1-infected and -free B. bassiana strains differentially modulate mosquito gut microbiota; the former reduces the bacterial genus Elizabethkingia and the latter Serratia. Co-transfection of mosquitos with B. bassiana and P. berghei revealed a reduction of ookinetes in the presence of BbPmV-1, potentially due to the upregulation of a mycotoxin. Finally, BbPmV-1-mediated hypovirulence is at least partially dependent on the A. coluzzii RNAi pathway, and silencing of the dicer-2 gene restores virulence. Taken together, our data clearly demonstrate the crucial role of mycovirus infection in mediating B. bassiana virulence against A. coluzzii and suggest that BbPmV-1 protects A. coluzzii from B. bassiana, the mosquito’s own immune system, potentially harmful gut microbiota, and Plasmodium parasites.

This work is aimed at formulating a mathematical model for the control of mosquito population using sterile insect technology (SIT). SIT is an environmental friendly method, which depends on the release of sterile male mosquitoes that compete with wild male mosquitoes and mate with wild female mosquitoes, which leads to the production of no offspring. The basic offspring number of the mosquitoes’ population was computed, after which we investigated the existence of two equilibrium points of the model. When the basic offspring number of the model M0, is less than or equal to 1, a mosquito extinction equilibrium point E2, which is often biologically unattainable, was shown to exits. On the other hand, if M0>1, we have the nonnegative equilibrium point E1 which is shown to be both locally and globally asymptotically stable whenever M0>1. Local sensitivity analysis was then performed to know the parameters that should be targeted by control intervention strategies and result shows that female mating probability to be with the sterile male mosquitoes ρS, mating rate of the sterile mosquito β2, and natural death rates of both aquatic and female mosquitoesμA+μF have greater impacts on the reduction and elimination of mosquitoes from a population. Simulation of the model shows that enough release of sterile male mosquitoes into the population of the wild mosquitoes controls the mosquito population and as such can reduce the spread of mosquito borne disease such as Zika.

Abstract Aedes vigilax (Skuse) is a pest and vector species associated with coastal wetlands and the abundance of this mosquito has been identified as contributing to increased risk of mosquito-borne disease outbreaks. As urban development continues to encroach on these coastal wetlands, pest and public health impacts are becoming of increasing concern and in the absence of broadscale mosquito control. Urban planners are looking to buffer zones and other land use planning options to minimize contact between mosquitoes and humans but gaps in the understanding of dispersal ranges of mosquitoes hamper the adoption of these strategies. A mark-release-recapture experiment was conducted to measure the dispersal of this mosquito from an urban estuarine wetland in Sydney, Australia. An estimated total of over 150,000 wild caught female mosquitoes were marked with fluorescent dust and then released. A network of 38 traps was then operated for 5 d within an area of 28 km2. A total of 280 marked mosquitoes was recaptured, representing less than 1% of the estimate 250,000 marked mosquitoes released. Marked mosquitoes were recaptured up to 3 km from the release point, providing an insight into the dispersal range of these mosquitoes. The mean distance traveled by marked mosquitoes was 0.83 km, a result reflecting the greater proportion of marked mosquitoes recaptured near release point. The findings of this study indicate that effective buffer zones between estuarine wetlands and high-density urban developments would be an impractical approach to minimizing pest and public health impacts associated with this mosquito.

AbstractAedes japonicus japonicus (Theobald) (Diptera: Culicidae), the Asian bush mosquito, is a keen biter linked to the transmission to humans of a variety of diseases. It has moved significantly from its historical Asian distribution, with its arrival in North America first noted in 1998 in New York and New Jersey, United States of America. Here we report the presence of A. j. japonicus within our collections of mosquitoes in the capital city of the easternmost province in Canada: St. John’s, Newfoundland and Labrador, in 2013. This observation provides further evidence of this mosquito’s ability to significantly expand its geographic range, potentially affecting connectivity between subpopulations globally.

Mosquito control is implemented when arboviruses are detected in patients or in field-collected mosquitoes. However, mass screening of mosquitoes is usually laborious and expensive, requiring specialized expertise and equipment. Detection of virus in mosquito saliva using honey-impregnated filter papers seems to be a promising method as it is non-destructive and allows monitoring the viral excretion dynamics over time from the same mosquito. Here we test the use of filter papers to detect chikungunya virus in mosquito saliva in laboratory conditions, before proposing this method in large-scale mosquito surveillance programs. We found that 0.9 cm2 cards impregnated with a 50% honey solution could replace the forced salivation technique as they offered a viral RNA detection until 7 days after oral infection of Aedes aegypti and Aedes albopictus mosquitoes with CHIKV.

To reduce the global burden of mosquito-borne diseases, e.g. dengue, malaria, the need to develop new control methods is to be highlighted. The sterile insect technique (SIT) and various genetic modification strategies, have a potential to contribute to a reversal of the current alarming disease trends. In our previous work, the ordinary differential equation (ODE) models with different releasing sterile mosquito strategies are investigated. However, in reality, implementing SIT and the releasing processes of sterile mosquitos are very complex. In particular, the delay phenomena always occur. To achieve suppression of wild mosquito populations, in this paper, we reassess the effect of the delayed releasing of sterile mosquitos on the suppression of interactive mosquito populations. We extend the previous ODE models to the delayed releasing models in two different ways of releasing sterile mosquitos, where both constant and exponentially distributed delays are considered, respectively. By applying the theory and methods of delay differential equations, the effect of time delays on the stability of equilibria in the system is rigorously analyzed. Some sustained oscillation phenomena via Hopf bifurcations in the system are observed. Numerical examples demonstrate rich dynamical features of the proposed models. Based on the obtained results, we also suggest some new releasing strategies for sterile mosquito populations.

Mosquitoes are vectors of pathogens, causing human and animal diseases. Their ability to adapt and expand worldwide increases spread of mosquito-borne diseases. Climate changes contribute in enhancing these “epidemic conditions”. Understanding the effect of weather variables on mosquito seasonality and host searching activity contributes towards risk control of the mosquito-borne disease outbreaks. To enable early detection of Aedes invasive species we developed a surveillance network for both invasive and native mosquitoes at the main point of entry for the first time in Cyprus. Mosquito sampling was carried out for one year (May 2017–June 2018), at bimonthly intervals around Limassol port. Morphological and molecular identification confirmed the presence of 5 species in the study region: Culex. pipiens, Aedes detritus, Ae. caspius, Culiseta longiareolata and Cs. annulata. No invasive Aedes mosquito species were detected. The Pearson’s correlation and multiple linear regression were used to compare number of sampled mosquitoes and weather variables for three most numerous species (Cx. pipiens, Ae. detritus and Ae. caspius). The population densities of the most numerous species were highest from February to April. Number of Cx. pipiens (−0.48), Ae. detritus (−0.40) and Ae. caspius (−0.38) specimens sampled was negatively correlated with average daily temperature. Monthly relative humidity showed positive correlation with the numbers of the species sampled, Cx. pipiens (0.66) Ae. detritus (0.68), and Ae. caspius (0.71). Mosquito abundance of Cx. pipiens (0.97) and Ae. detritus (0.98) was strongly correlated to seasonal precipitation as well. Our work is a stepping stone to further stimulate implementation of International Health Regulations and implementation of early warning surveillance system for detection of invasive Aedes mosquitoes, native mosquitoes and arboviruses they may transmit. A network for the surveillance of both invasive and native mosquito species at the main point of entry for the first time in Cyprus was developed. Number of mosquitoes sampled was correlated with weather factors to identify parameters that might predict mosquito activity and species distribution to the prevention of international spread of vector mosquitoes and vector-borne diseases.

Full textAbstract:
ABSTRACT The response of mosquitoes to bushfire is poorly understood. During the 2019–20 summer, many regions of Australia were impacted by devastating bushfires. An area of estuarine and brackish-water wetlands alongside the Georges River, Sydney, New South Wales, was burned in January 2020. Mosquito populations within the area were monitored as part of the local authority's mosquito management program, providing a unique opportunity to record the response of key mosquitoes of pest and public health concern to bushfire. Ground pools within a tidally influenced swamp oak forest dominated by Casuarina glauca and associated wetlands dominated by Phragmites australis and Bolboschoenus spp. had been identified as suitable habitat for a range of mosquitoes, including Aedes alternans, Ae. vigilax, and Verrallina funerea. Surveys of immature stages of mosquitoes within recently burned habitats inundated by tides demonstrated that mosquito eggs survived the direct and indirect impacts of fire and immature stages successfully completed development as reflected in concomitant changes in adult mosquito populations following the bushfire. This unique observation has implications for mosquito management following bushfire in Australia and internationally.

Mosquitoes are highly active vectors capable of transmitting various pathogenic and infectious diseases to humans and animals. The present study was designed to identify the major species of mosquitoes and mosquito-borne flaviviruses (Saint Louis Encephalitis, West Nile and Dengue Viruses) prevalent in three districts of Punjab representing the three agro-geoclimatic zones viz; Multan, Chakwal and Jhang. The collected mosquitoes were stereoscopically identified to confirm the species and sex of the mosquitoes. Stereoscopic identification confirmed that female mosquitoes were 4334 out of 10675 (40.6%), 2242 out of 7296 (30%) and 2040 out of 6450 (31.6%) from districts Chakwal, Jhang and Multan, respectively. It was concluded that Culex species were present in abundance (73.2%) as compared to Aedes species (26.7%) in the selected study districts. The results of multiplex RT-PCR depicted that Dengue, West Nile, Japanese encephalitis and Saint Louis encephalitis viruses were prevalent in the mosquitoes of all three selected districts. However, the prevalence of mosquito-borne viruses insignificantly varied (P>0.05) among the three districts. This study has provided a better understanding of the prevailing mosquito species and mosquito-borne viruses in the study districts that can help to devise appropriate control measures

Background and Aim: Studies to determine abundance, distribution, species composition, and mosquito interactions are very important in understanding the risk of disease transmission to implement appropriate mosquito management in endemic areas. Lymphatic filarial worms are one of the parasites that are contracted and/or transmitted by mosquitoes when sucking the blood of infected humans or animals and then biting others. This research was conducted to study the abundance, species composition, mosquito biting cycles, density and periodicity of mosquitoes caught in Lubuk Pauh Village, Bulang Tengah Suku Ulu, Musi Rawas, South Sumatera, Indonesia, which is an endemic area of zoonotic Brugia malayi. Materials and Methods: The mosquito collection was done in July 2018 using the human landing collection method for 11 h from 18.00 pm to 5.00 am Western Indonesian Time. The catching of mosquitoes was done both indoors and outdoors, and mosquitoes were identified under a dissecting microscope using an identification key to confirm their species. Detection of B. malayi larvae in mosquitoes was confirmed by dissection and polymerase chain reaction methods. Results: The caught mosquitoes consisted of four species: Armigeres subalbatus, Culex quinquefasciatus, Culex vishnui, and Mansonia uniformis. Based on the Shannon–Wiener index, Lubuk Pauh Village has low mosquito species diversity (0.210). Ar. subalbatus was the dominant mosquito in Lubuk Pauh Village with dominance number 95.08, and it had the most frequent activity in each of periods of indoor and outdoor collection, with the highest density (man-hour density) at 18.00-19.00 (51.750). B. malayi infective stage larvae were not found in all mosquito species caught. Conclusion: Existence of Ar. subalbatus, Cx. quinquefasciatus, and Ma. uniformis in Lubuk Pauh Village which is an endemic area of B. malayi shows that the area is at risk of lymphatic filariasis transmission.

Full textAbstract:
This article presents an analysis of studies on harmful effects of blood-sucking mosquitoes (Diptera: Culicidae), which are one of the components of the gnat complex. Many individuals of this family are vectors of pathogens for a number of invasive and infectious diseases that are dangerous for animals and humans. The relevance of this study lies in the fact that today, climate warming and urbanization lead to expansion of the area of mosquitos, increase in their number, and as a result, the spread of diseases to new territories of Russia. Mosquito bites are accompanied by damage to the skin of a victim, a feeder, and introduction of toxic saliva which has a strong anticoagulant and hemolytic effect. Erythema, inflammation and itching are developed at the place of the insect bite. Multiple bites cause edema, and increased body temperature and local inflammation. It is difficult to estimate losses caused by mosquitoes to agriculture due to the fact that mosquitoes attack cattle together with other blood-sucking dipterans: horseflies, blackflies and sandflies. A massive attack of insects causes anxiety in cattle, disrupts normal grazing of livestock, and results in injuries caused by movements to protect themselves from insects, which leads to disruption of normal grazing and a decrease in their productivity.

Biodiversitas 20: 468-473. Mosquito is a medically important insect, which is a vector to transmit pathogens to humans. There are several methods to reduce the numbers mosquitoes, which requires entomological knowledge. It is critical to know the species of mosquitoes in the area to choose the most suitable method to provide vector control, specifically, to target mosquito species. In this study, we investigated the species of mosquito vectors in the Huay Nam Nak Village in the Suan Phueng District, Ratchaburi Province, Thailand, which is an endemic area of mosquito-borne diseases, especially malaria and dengue fever. Mosquito species were collected by the Mosquito Magnet® Independence trap from the Huay Nam Nak Village. A total of 1,002 mosquitoes, divided into eight species in four genera, including Anopheles barbirostris s.l. van der Wulp (118 individuals), An. subpictus s.l. Grassi (127 individuals), Culex quinquefasciatus Say (186 individuals), Cx. vishnui Theobald (204 individuals), Cx. whitmorei Giles (198 individuals), Aedes aegypti Linnaeus (45 individuals), Ae. albopictus Skuse (78 individuals), and Armigeres subalbatus Coquillett (46 individuals). This checklist of the mosquito species is very important information to set mosquito control measures that suit each area.
