| complement-related proteins control the flavivirus infection of aedes aegypti by inducing antimicrobial peptides. | the complement system functions during the early phase of infection and directly mediates pathogen elimination. the recent identification of complement-like factors in arthropods indicates that this system shares common ancestry in vertebrates and invertebrates as an immune defense mechanism. thioester (te)-containing proteins (teps), which show high similarity to mammalian complement c3, are thought to play a key role in innate immunity in arthropods. herein, we report that a viral recognition ... | 2014 | 24722701 |
| evaluation of the effectiveness of mass trapping with bg-sentinel traps for dengue vector control: a cluster randomized controlled trial in manaus, brazil. | the objective of this study was to assess the effectiveness of bg-sentinel (bgs) traps for mass trapping at the household level to control the dengue vector, aedes aegypti (l.), in manaus (brazil) by performing a cluster randomized controlled trial. after an initial questionnaire and baseline monitoring, 6 out of 12 clusters were randomly allocated to the intervention arm, where participating premises received one bgs trap for mass trapping. the other six clusters did not receive traps and were ... | 2014 | 24724291 |
| sublethal effect of pyriproxyfen released from a fumigant formulation on fecundity, fertility, and ovicidal action in aedes aegypti (diptera: culicidae). | dengue and dengue hemorrhagic fever are mosquito-borne viral diseases that coincide with the distribution of aedes aegypti (l.), the primary vector in the tropical and semitropical world. with no available vaccine, controlling the dengue vector is essential to prevent epidemics. the effects of the insect growth regulator pyriproxyfen on ae. aegypti adults that survived a treatment with a sublethal dose were investigated in the laboratory, including effects on their reproductive potential. pyripr ... | 2014 | 24724294 |
| genome-wide snps lead to strong signals of geographic structure and relatedness patterns in the major arbovirus vector, aedes aegypti. | genetic markers are widely used to understand the biology and population dynamics of disease vectors, but often markers are limited in the resolution they provide. in particular, the delineation of population structure, fine scale movement and patterns of relatedness are often obscured unless numerous markers are available. to address this issue in the major arbovirus vector, the yellow fever mosquito (aedes aegypti), we used double digest restriction-site associated dna (ddrad) sequencing for t ... | 2014 | 24726019 |
| larval competition extends developmental time and decreases adult size of wmelpop wolbachia-infected aedes aegypti. | the intracellular endosymbiont wolbachia has been artificially transinfected into the dengue vector aedes aegypti, where it is being investigated as a potential dengue biological control agent. invasion of wolbachia in natural populations depends upon the fitness of wolbachia-infected ae. aegypti relative to uninfected competitors. although wolbachia infections impose fitness costs on the adult host, effects at the immature stages are less clear, particularly in competitive situations. we look f ... | 2014 | 24732463 |
| air travel is associated with intracontinental spread of dengue virus serotypes 1-3 in brazil. | dengue virus and its four serotypes (denv-1 to denv-4) infect 390 million people and are implicated in at least 25,000 deaths annually, with the largest disease burden in tropical and subtropical regions. we investigated the spatial dynamics of denv-1, denv-2 and denv-3 in brazil by applying a statistical framework to complete genome sequences. for all three serotypes, we estimated that the introduction of new lineages occurred within 7 to 10-year intervals. new lineages were most likely to be i ... | 2014 | 24743730 |
| winter refuge for aedes aegypti and ae. albopictus mosquitoes in hanoi during winter. | dengue occurs throughout the year in hanoi, vietnam, despite winter low temperatures <10°c. during july 2010 to march 2012, we surveyed monthly for aedes larvae and pupae in 120 houses in 8 hanoi districts. aedes albopictus preferred discarded containers in summer and pupal density drastically decreased in winter. aedes aegypti preferred concrete tanks and this preference increased in winter. even in winter, the lowest water temperature found in concrete tanks was >14°c, exceeding the developmen ... | 2014 | 24752230 |
| survival and swimming behavior of insecticide-exposed larvae and pupae of the yellow fever mosquito aedes aegypti. | the yellow fever mosquito aedes aegypti is essentially a container-inhabiting species that is closely associated with urban areas. this species is a vector of human pathogens, including dengue and yellow fever viruses, and its control is of paramount importance for disease prevention. insecticide use against mosquito juvenile stages (i.e. larvae and pupae) is growing in importance, particularly due to the ever-growing problems of resistance to adult-targeted insecticides and human safety concern ... | 2014 | 24761789 |
| development and evaluation of a novel contamination device that targets multiple life-stages of aedes aegypti. | the increasing global threat of dengue demands new and easily applicable vector control methods. ovitraps provide a low-tech and inexpensive means to combat dengue vectors. here we describe the development and optimization process of a novel contamination device that targets multiple life-stages of the aedes aegypti mosquito. special focus is directed to the diverse array of control agents deployed in this trap, covering adulticidal, larvicidal and autodissemination impacts. | 2014 | 24766772 |

| genetic shifting: a novel approach for controlling vector-borne diseases. | rendering populations of vectors of diseases incapable of transmitting pathogens through genetic methods has long been a goal of vector geneticists. we outline a method to achieve this goal that does not involve the introduction of any new genetic variants to the target population. rather we propose that shifting the frequencies of naturally occurring alleles that confer refractoriness to transmission can reduce transmission below a sustainable level. the program employs methods successfully use ... | 2014 | 24794113 |
| spatio-temporal dynamics of dengue 2009 outbreak in córdoba city, argentina. | during 2009 the biggest dengue epidemic to date occurred in argentina, affecting almost half the country. we studied the spatio-temporal dynamics of the outbreak in the second most populated city of the country, córdoba city. confirmed cases and the results of an aedes aegypti monitoring during the outbreak were geolocated. the imported cases began in january, and the autochthonous in march. thirty-three percent of the 130 confirmed cases were imported, and occurred mainly at the center of the c ... | 2014 | 24795212 |
| multi-scale analysis of the associations among egg, larval and pupal surveys and the presence and abundance of adult female aedes aegypti (stegomyia aegypti) in the city of merida, mexico. | despite decades of research, there is still no agreement on which indices of aedes aegypti (stegomyia aegypti) (diptera: culicidae) presence and abundance better quantify entomological risk for dengue. this study reports the results of a multi-scale, cross-sectional entomological survey carried out in 1160 households in the city of merida, mexico to establish: (a) the correlation between levels of ae. aegypti presence and abundance detected with aspirators and ovitraps; (b) which immature and eg ... | 2014 | 24797405 |
| wolbachia infection does not alter attraction of the mosquito aedes (stegomyia) aegypti to human odours. | the insect endosymbiont wolbachia pipientis (rickettsiales: rickettsiaceae) is undergoing field trials around the world to determine if it can reduce transmission of dengue virus from the mosquito stegomyia aegypti to humans. two different wolbachia strains have been released to date. the primary effect of the wmel strain is pathogen protection whereby infection with the symbiont limits replication of dengue virus inside the mosquito. a second strain, wmelpop, induces pathogen protection, reduce ... | 2014 | 24797695 |
| influence of mosquito genotype on transcriptional response to dengue virus infection. | the mosquito aedes aegypti is the principal vector that transmits dengue virus (denv) to humans. the primary factors that trigger a susceptible or refractory interaction of a. aegypti with denv are not well understood. in this study, our aim is to characterize the influence of vector genotype on differential gene expression of susceptible vs. refractory a. aegypti strains to denv infection. to accomplish that, we identified differential expression of a set of complementary dnas (cdnas; n = 9,504 ... | 2014 | 24798794 |
| geometric morphometrics of nine field isolates of aedes aegypti with different resistance levels to lambda-cyhalothrin and relative fitness of one artificially selected for resistance. | aedes aegypti, a mosquito closely associated with humans, is the principal vector of dengue virus which currently infects about 400 million people worldwide. because there is no way to prevent infection, public health policies focus on vector control; but insecticide-resistance threatens them. however, most insecticide-resistant mosquito populations exhibit fitness costs in absence of insecticides, although these costs vary. research on components of fitness that vary with insecticide-resistance ... | 2014 | 24801598 |
| comparing dengue and chikungunya emergence and endemic transmission in a. aegypti and a. albopictus. | chikungunya and dengue are re-emerging mosquito-borne infectious diseases that are of increasing concern as human travel and expanding mosquito ranges increase the risk of spread. we seek to understand the differences in transient and endemic behavior of chikungunya and dengue; risk of emergence for different virus-vector assemblages; and the role that virus evolution plays in disease dynamics and risk. to address these questions, we adapt a mathematical mosquito-borne disease model to chikungun ... | 2014 | 24801860 |
| chemical composition and larvicidal activity of plant extracts from clausena dentata (willd) (rutaceae) against dengue, malaria, and filariasis vectors. | mosquitoes in the larval stage are attractive targets for pesticides because mosquitoes breed in water, and thus, it is easy to deal with them in this habitat. the use of conventional pesticides in the water sources, however, introduces many risks to people and/or the environment. natural pesticides, especially those derived from plants, are more promising in this aspect. aromatic plants and their essential oils are very important sources of many compounds that are used in different respects. in ... | 2014 | 24802866 |
