| dispersal and other population parameters of aedes aegypti in an african village and their possible significance in epidemiology of vector-borne diseases. | dispersal of aedes aegypti aegypti adults within shauri moyo, an african village in the rabai area north of mombasa, kenya, was studied using the mark-release-recapture method. a total of 920 mosquitoes were captured and uniquely marked, of which 828 (90%) were released and 332 (40%) recaptured. a great majority of mosquitoes were recaptured once, but some individuals were recaptured up to 10 times. most females visited 1 or 2 houses (40.8%, 44.9%, respectively), but there were females that visi ... | 1986 | 3789275 |
| estimates of population size, dispersal, and longevity of domestic aedes aegypti aegypti (diptera: culicidae) by mark-release-recapture in the village of shauri moyo in eastern kenya. | estimates of the absolute size of a domestic population of aedes aegypti aegypti (l.) were made in the rabai area of kenya, based on a single release, followed by either single or repeated recaptures. from single recapture within 24 h of release, the size of the female ae. a. aegypti population in the shauri moyo village was estimated by the lincoln index to be 365. using a single release and repeated recaptures, population size was estimated by jackson's positive method to be 337. depletion of ... | 1995 | 7869339 |
| quantitative genetics of vector competence for dengue-2 virus in aedes aegypti. | a quantitative genetic study of the ability of aedes aegypti to propagate dengue-2 (den-2) virus in the midgut and in a disseminated infection in the head was conducted with a standard half-sib breeding design. aedes aegypti aegypti and a. aegypti formosus differ markedly in oral susceptibility to den-2 virus. mosquitoes were orally infected and, after an extrinsic incubation period of 14 days, virus titer (by tissue culture infectious dose, 50% endpoint) was determined in the midgut (mt) and he ... | 1998 | 9886207 |
| gene flow, subspecies composition, and dengue virus-2 susceptibility among aedes aegypti collections in senegal. | aedes aegypti, the "yellow fever mosquito", is the primary vector to humans of the four serotypes of dengue viruses (denv1-4) and yellow fever virus (yfv) and is a known vector of chikungunya virus. there are two recognized subspecies of ae. aegypti sensu latu (s.l.): the presumed ancestral form, ae. aegypti formosus (aaf), a primarily sylvan mosquito in sub-saharan africa, and ae. aegypti aegypti (aaa), found globally in tropical and subtropical regions typically in association with humans. the ... | 2009 | 19365540 |
| evidence of multiple chromosomal inversions in aedes aegypti formosus from senegal. | chromosomal inversions are prevalent in mosquito species but polytene chromosomes are difficult to prepare and visualize in members of the tribe aedinii and thus there exists only indirect evidence of inversions. we constructed an f(1) intercross family using a p(1) female from a laboratory strain of aedes aegypti aegypti (aaa) and a p(1) male aedes aegypti formosus (aaf) from a strain collected from south-eastern senegal. recombination rates in the f(2) offspring were severely reduced and genot ... | 2009 | 19754736 |
| the queenslandensis and the type form of the dengue fever mosquito (aedes aegypti l.) are genomically indistinguishable. | the mosquito aedes aegypti (l.) is a major vector of viral diseases like dengue fever, zika and chikungunya. aedes aegypti exhibits high morphological and behavioral variation, some of which is thought to be of epidemiological significance. globally distributed domestic ae. aegypti have often been grouped into (i) the very pale variety queenslandensis and (ii) the type form. because the two color forms co-occur across most of their range, there is interest in understanding how freely they interb ... | 2016 | 27806047 |
| effect of quorum sensing by staphylococcus epidermidis on the attraction response of female adult yellow fever mosquitoes, aedes aegypti aegypti (linnaeus) (diptera: culicidae), to a blood-feeding source. | aedes aegypti, the principal vector of yellow fever and dengue fever, is responsible for more than 30,000 deaths annually. compounds such as carbon dioxide, amino acids, fatty acids and other volatile organic compounds (vocs) have been widely studied for their role in attracting ae. aegypti to hosts. many vocs from humans are produced by associated skin microbiota. staphyloccocus epidermidis, although not the most abundant bacteria according to surveys of relative 16s ribosomal rna abundance, co ... | 2015 | 26674802 |
| abundant aedes (stegomyia) aegypti aegypti mosquitoes in the 2014 dengue outbreak area of mozambique. | in early 2014, dengue cases were reported from northern mozambique, 30 years after the last outbreak. we identified potential dengue vector species in three northern towns, pemba, nampula and nacala, and one southern town, maputo, during the outbreak in april 2014. a major dengue vector species, aedes (stegomyia) aegypti, was found in all these towns. the dominant vector subspecies in the northern towns was aedes aegypti aegypti, while ae. aegypti formosus was dominant in maputo. considering the ... | 2015 | 26060423 |
| aedes aegypti (diptera: culicidae) in mauritania: first report on the presence of the arbovirus mosquito vector in nouakchott. | aedes aegypti l. (diptera: culicidae) is a major vector of yellow fever, dengue, and chikungunya viruses throughout tropical and subtropical areas of the world. although the southernmost part of mauritania along the senegal river has long been recognized at risk of yellow fever transmission, aedes spp. mosquitoes had never been reported northwards in mauritania. here, we report the first observation of aedes aegypti aegypti (l.) and aedes (ochlerotatus) caspius (pallas, 1771) in the capital city ... | 2015 | 26335483 |
| geographical distribution of aedes aegypti aegypti and aedes aegypti formosus (diptera: culicidae) in kenya and environmental factors related to their relative abundance. | the mosquito aedes aegypti (l.) is the primary vector of various infectious viruses and is typified by a polymorphic color and abundance of white scales on the body. it has been conventionally separated into two subspecies, ae. aeg. formosus (walker) (aaf) and ae. aeg. aegypti (l.) (aaa), with aaf considered a 'sylvan' form and aaa a 'domestic' form. because the two subspecies show different susceptibilities to dengue viruses it is important to understand their distribution. in this study, we co ... | 2019 | 31815285 |
| vgsc-interacting proteins are genetically associated with pyrethroid resistance in aedes aegypti. | association mapping of factors that condition pyrethroid resistance in aedes aegypti has consistently identified genes in multiple functional groups. toward better understanding of the mechanisms involved, we examined high throughput sequencing data (hts) from two aedes aegypti aegypti collections from merida, yucatan, mexico treated with either permethrin or deltamethrin. exome capture enrichment for coding regions and the aaegl5 annotation were used to identify genes statistically associated w ... | 2019 | 30695054 |
