| modelling optimum use of attractive toxic sugar bait stations for effective malaria vector control in africa. | the development of insecticide resistance and the increased outdoor-biting behaviour of malaria vectors reduce the efficiency of indoor vector control methods. attractive toxic sugar baits (atsbs), a method targeting the sugar-feeding behaviours of vectors both indoors and outdoors, is a promising supplement to indoor tools. the number and configuration of these atsb stations needed for malaria control in a community needs to be determined. | 2015 | 26643110 |
| progress toward malaria elimination in jazan province, kingdom of saudi arabia: 2000-2014. | the draft global technical strategy for malaria aims to eliminate malaria from at least 10 countries by 2020. yemen and saudi arabia remain the last two countries on the arabian peninsula yet to achieve elimination. over the last 50 years, systematic efforts to control malaria in the kingdom of saudi arabia has successfully reduced malaria cases to a point where malaria is now constrained largely to jazan province, the most south-western area along the red sea. the progress toward elimination in ... | 2015 | 26552387 |
| diversification of the genus anopheles and a neotropical clade from the late cretaceous. | the anopheles genus is a member of the culicidae family and consists of approximately 460 recognized species. the genus is composed of 7 subgenera with diverse geographical distributions. despite its huge medical importance, a consensus has not been reached on the phylogenetic relationships among anopheles subgenera. we assembled a comprehensive dataset comprising the coi, coii and 5.8s rrna genes and used maximum likelihood and bayesian inference to estimate the phylogeny and divergence times o ... | 2015 | 26244561 |
| formulation of attractive toxic sugar bait (atsb) with safe epa-exempt substance significantly diminishes the anopheles sergentii population in a desert oasis. | attractive toxic sugar bait (atsb) is a highly effective method which targets mosquitoes based on their sugar foraging behavior, by presenting baits of attractive compounds in combination with sugar and oral toxin to local mosquito populations. environmental concerns and insecticide selection-pressure have prompted investigations of novel, ecologically-harmless substances which can be used as insecticides. this study examined the efficacy of microencapsulated garlic-oil as the oral toxin compone ... | 2015 | 26119042 |
| analysing the oviposition behaviour of malaria mosquitoes: design considerations for improving two-choice egg count experiments. | choice egg-count bioassays are a popular tool for analysing oviposition substrate preferences of gravid mosquitoes. this study aimed at improving the design of two-choice experiments for measuring oviposition substrates preferences of the malaria vector anopheles gambiae senso lato, a mosquito that lays single eggs. | 2015 | 26088669 |
| decrease of larval and subsequent adult anopheles sergentii populations following feeding of adult mosquitoes from bacillus sphaericus-containing attractive sugar baits. | bacillus sphaericus is a mosquito-larvae pathogen which proliferates in the host cadavers, spreading and preserving the infection within the larval habitats for prolonged periods. in this pilot field study, we presented b. sphaericus-containing attractive sugar baits (asb) to wild anopheles sergentii adults, with the assumption that bait-fed, b. sphaericus-carrying mosquitoes are able to efficiently transmit the pathogen to the larval habitats, causing larval mortality and leading to a decrease ... | 2015 | 25899788 |

| the malaria transition on the arabian peninsula: progress toward a malaria-free region between 1960-2010. | the transmission of malaria across the arabian peninsula is governed by the diversity of dominant vectors and extreme aridity. it is likely that where malaria transmission was historically possible it was intense and led to a high disease burden. here, we review the speed of elimination, approaches taken, define the shrinking map of risk since 1960 and discuss the threats posed to a malaria-free arabian peninsula using the archive material, case data and published works. from as early as the 194 ... | 0 | 23548086 |
| the effects of urbanization on global plasmodium vivax malaria transmission. | many recent studies have examined the impact of urbanization on plasmodium falciparum malaria endemicity and found a general trend of reduced transmission in urban areas. however, none has examined the effect of urbanization on plasmodium vivax malaria, which is the most widely distributed malaria species and can also cause severe clinical syndromes in humans. in this study, a set of 10,003 community-based p. vivax parasite rate (pvpr) surveys are used to explore the relationships between pvpr i ... | 2012 | 23217010 |
| anopheles plumbeus (diptera: culicidae) in europe: a mere nuisance mosquito or potential malaria vector? | anopheles plumbeus has been recognized as a minor vector for human malaria in europe since the beginning of the 20th century. in recent years this tree hole breeding mosquito species appears to have exploited novel breeding sites, including large and organically rich man-made containers, with consequently larger mosquito populations in close vicinity to humans. this lead to investigate whether current populations of an. plumbeus would be able to efficiently transmit plasmodium falciparum, the pa ... | 2012 | 23181931 |
| linking land cover and species distribution models to project potential ranges of malaria vectors: an example using anopheles arabiensis in sudan and upper egypt. | anopheles arabiensis is a particularly opportunistic feeder and efficient vector of plasmodium falciparum in africa and may invade areas outside its normal range, including areas separated by expanses of barren desert. the purpose of this paper is to demonstrate how spatial models can project future irrigated cropland and potential, new suitable habitat for vectors such as an. arabiensis. | 2012 | 22866895 |
| abundance and dynamics of anopheline larvae in a highland malarious area of south-central ethiopia. | malaria is a public health problem in ethiopia, and increasingly so in highland areas, possibly because of global warming. this study describes the distribution, breeding habitat and monthly dynamics of anopheline larvae in butajira, a highland area in south-central ethiopia. | 2012 | 22695178 |
| attractive toxic sugar bait (atsb) methods decimate populations of anopheles malaria vectors in arid environments regardless of the local availability of favoured sugar-source blossoms. | attractive toxic sugar bait (atsb) methods are a new and promising "attract and kill" strategy for mosquito control. sugar-feeding female and male mosquitoes attracted to atsb solutions, either sprayed on plants or in bait stations, ingest an incorporated low-risk toxin such as boric acid and are killed. this field study in the arid malaria-free oasis environment of israel compares how the availability of a primary natural sugar source for anopheles sergentii mosquitoes: flowering acacia raddian ... | 2012 | 22297155 |
| modelling the global constraints of temperature on transmission of plasmodium falciparum and p. vivax. | abstract: background: temperature is a key determinant of environmental suitability for transmission of human malaria, modulating endemicity in some regions and preventing transmission in others. the spatial modelling of malaria endemicity has become increasingly sophisticated and is now central to the global scale planning, implementation, and monitoring of disease control and regional efforts towards elimination, but existing efforts to model the constraints of temperature on the malaria lands ... | 2011 | 21615906 |
| geographic profiling as a novel spatial tool for targeting infectious disease control. | abstract: geographic profiling is a statistical tool originally developed in criminology to prioritise large lists of suspects in cases of serial crime. here, we use two data sets - one historical and one modern - to show how it can be used to locate the sources of infectious disease. results: first, we re-analyse data from a classic epidemiological study, the 1854 london cholera outbreak. using 321 disease sites as input, we evaluate the locations of 13 neighbourhood water pumps. the broad stre ... | 2011 | 21592339 |
| natural plant sugar sources of anopheles mosquitoes strongly impact malaria transmission potential. | an improved knowledge of mosquito life history could strengthen malaria vector control efforts that primarily focus on killing mosquitoes indoors using insecticide treated nets and indoor residual spraying. natural sugar sources, usually floral nectars of plants, are a primary energy resource for adult mosquitoes but their role in regulating the dynamics of mosquito populations is unclear. to determine how the sugar availability impacts anopheles sergentii populations, mark-release-recapture stu ... | 2011 | 21283732 |
