| identification of candidate iron transporters from the zip/znt gene families in the mosquito aedes aegypti. | mosquito-transmitted viral pathogens, such as dengue and zika, afflict tens of thousands of people every year. these viruses are transmitted during the blood-feeding process that is required for mosquito reproduction, the most important vector being aedes aegypti. while vertebrate blood is rich in protein, its high iron content is potentially toxic to mosquitoes. although iron transport and sequestration are essential in the reproduction of vector mosquitoes, we discovered that culicine mosquito ... | 2018 | 29706902 |
| parallel evolution of vgsc mutations at domains is6, iis6 and iiis6 in pyrethroid resistant aedes aegypti from mexico. | aedes aegypti is the primary urban mosquito vector of viruses causing dengue, zika and chikungunya fevers -for which vaccines and effective pharmaceuticals are still lacking. current strategies to suppress arbovirus outbreaks include removal of larval-breeding sites and insecticide treatment of larval and adult populations. insecticidal control of ae. aegypti is challenging, due to a recent rapid global increase in knockdown-resistance (kdr) to pyrethroid insecticides. widespread, heavy use of p ... | 2018 | 29712956 |
| efficacy of larvicides for the control of dengue, zika, and chikungunya vectors in an urban cemetery in southern mexico. | many countries in latin america have recently experienced outbreaks of zika and chikungunya fever, in additional to the usual burden imposed by dengue, all of which are transmitted by aedes aegypti in this region. to identify potential larvicides, we determined the toxicity of eight modern insecticides to a. aegypti larvae from a colony that originated from field-collected insects in southern mexico. the most toxic compounds were pyriproxyfen (which prevented adult emergence) and λ-cyhalothrin, ... | 2018 | 29713901 |
| dehydration prompts increased activity and blood feeding by mosquitoes. | current insights into the mosquito dehydration response rely on studies that examine specific responses but ultimately fail to provide an encompassing view of mosquito biology. here, we examined underlying changes in the biology of mosquitoes associated with dehydration. specifically, we show that dehydration increases blood feeding in the northern house mosquito, culex pipiens, which was the result of both higher activity and a greater tendency to land on a host. similar observations were noted ... | 2018 | 29717151 |
| high throughput discovery of protein variants using proteomics informed by transcriptomics. | proteomics informed by transcriptomics (pit), in which proteomic ms/ms spectra are searched against open reading frames derived from de novo assembled transcripts, can reveal previously unknown translated genomic elements (tges). however, determining which tges are truly novel, which are variants of known proteins, and which are simply artefacts of poor sequence assembly, is challenging. we have designed and implemented an automated solution that classifies putative tges by comparing to referenc ... | 2018 | 29718325 |
| vector competence of certain culex and aedes mosquitoes for the chittoor virus, the indian variant of the batai virus. | chittoor virus (chitv), a mosquito-borne bunyavirus (orthobunyavirus: bunyaviridae) isolated in india, has been found to be antigenically close to the batai virus (batv), which has a wide distribution across asia, europe, and africa. the latter virus causes influenza-like illness in humans and mild illness in sheep and goats. batv has been involved in genetic reassortment with other bunyaviruses, generating novel genome combinations and causing severe clinical manifestations including hemorrhagi ... | 2018 | 29718685 |
| wolbachia significantly impacts the vector competence of aedes aegypti for mayaro virus. | wolbachia, an intracellular endosymbiont present in up to 70% of all insect species, has been suggested as a sustainable strategy for the control of arboviruses such as dengue, zika and chikungunya. as mayaro virus outbreaks have also been reported in latin american countries, the objective of this study was to evaluate the vector competence of brazilian field-collected ae. aegypti and the impact of wolbachia (wmel strain) upon this virus. our in vitro studies with aag2 cells showed that mayaro ... | 2018 | 29720714 |
| contributions from the silent majority dominate dengue virus transmission. | despite estimates that, each year, as many as 300 million dengue virus (denv) infections result in either no perceptible symptoms (asymptomatic) or symptoms that are sufficiently mild to go undetected by surveillance systems (inapparent), it has been assumed that these infections contribute little to onward transmission. however, recent blood-feeding experiments with aedes aegypti mosquitoes showed that people with asymptomatic and pre-symptomatic denv infections are capable of infecting mosquit ... | 2018 | 29723307 |
| larval density mediates knockdown resistance to pyrethroid insecticides in adult aedes aegypti. | understanding mechanisms driving insecticide resistance in vector populations remains a public health priority. to date, most research has focused on the genetic mechanisms underpinning resistance, yet it is unclear what role environmental drivers may play in shaping phenotypic expression. one of the key environmental drivers of aedes aegypti mosquito population dynamics is resource-driven intraspecific competition at the larval stage. we experimentally investigated the role of density-dependent ... | 2018 | 29724237 |
| advising a woman with suspected zika virus infection. | the zika virus (zikv) epidemic is spreading: 67 countries are now reporting transmission, and over 2,000 cases of congenital zika syndrome (czs) have been confirmed. the heaviest burden has been borne by those living where poverty, poor infrastructure, and lack of access to health services are common and the penetration of aedes aegypti is high. because most cases are asymptomatic, the most dramatic signs of the disease appear through the czs cases. in spite of the need for disaggregated epidemi ... | 2018 | 29724698 |
| improving the delivery and efficiency of fungus-impregnated cloths for control of adult aedes aegypti using a synthetic attractive lure. | entomopathogenic fungi are highly promising agents for controlling aedes aegypti mosquitoes. deploying fungus-impregnated black cloths in pet traps efficiently reduced ae. aegypti female survival rates under intra-domicile conditions. with the aim of further increasing the effectiveness of the traps, the addition of attractive lures to fungus-impregnated traps was evaluated. | 2018 | 29728121 |
| male contributions during mating increase female survival in the disease vector mosquito aedes aegypti. | aedes aegypti is a vector of medically important viruses including those causing zika, dengue, and chikungunya. during mating, males transfer a number of proteins and other molecules to the female and these components of the male ejaculate are essential in shifting female post-mating behaviors in a number of insect species. because these molecules are highly variable by species, and female post-mating behavior by species is also varied, behavioral assays testing the function of the ejaculate are ... | 2018 | 29729859 |
