| the susceptibility of five laboratory colonies of mosquitoes to the human nematode wuchereria bancrofti (cobbold). | laboratory colonies of anopheles gambiae, an. arabiensis, an. merus, an. quadriannulatus and aedes aegypti formosus were artificially fed on blood containing microfilariae of wuchereria bancrofti. the anopheline colonies all supported parasite development to the infective stage, with an. quadriannulatus being the most heavily infected. the parasite did not develop at all in the ae. aegypti formosus colony. | 1990 | 2260902 |
| experimental assessment of bedbugs (cimex lectularius and cimex hemipterus) and mosquitoes (aedes aegypti formosus) as vectors of human immunodeficiency virus. | in vitro experiments were conducted to assess whether bedbugs (cimex lectularius and cimex hemipterus) and mosquitoes (aedes aegypti formosus) could act as vectors of hiv. these insects engorged through a membrane on a blood-virus mixture. female bedbugs were larger than males and took larger blood-meals when fed to repletion. it was determined that the full blood-meal of a female bedbug contained 0.09 x 10(5) tissue culture infectious doses (tcid) of virus and a male 0.07 x 10(5) tcid, while pa ... | 1987 | 2450552 |
| [oral receptivity of aedes aegypti formosus from franceville (gabon, central africa) for type 2 dengue virus]. | dengue is widely distributed in the tropics but epidemic activity was rarely reported in africa before the 1980's. in the past 15 years, increased epidemic dengue fever has been reported both in east and west africa, raising concern about the ability of local populations of aedes aegypti to transmit dengue viruses. ae. aegypti is present in two forms in africa: ae. aegypti aegypti and ae. aegypti formosus. this latter form, much darker, was not originally a local species but is now colonizing ar ... | 1999 | 10690473 |
| 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 |
| larval ecology of mosquitoes in sylvatic arbovirus foci in southeastern senegal. | although adult mosquito vectors of sylvatic arbovirus [yellow fever (yfv), dengue-2 (denv-2) and chikungunya (chikv)] have been studied for the past 40 years in southeastern senegal, data are still lacking on the ecology of larval mosquitoes in this area. in this study, we investigated the larval habitats of mosquitoes and characterized their seasonal and spatial dynamics in arbovirus foci. | 2012 | 23216815 |
| 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 |
| reproductive incompatibility involving senegalese aedes aegypti (l) is associated with chromosome rearrangements. | aedes aegypti, the primary vector of dengue, yellow fever and zika flaviviruses, consists of at least two subspecies. aedes aegypti (aaa) is light in color, has pale scales on the first abdominal tergite, oviposits in artificial containers, and preferentially feeds on humans. aedes aegypti formosus (aaf), has a dark cuticle, is restricted to sub-saharan africa, has no pale scales on the first abdominal tergite and frequently oviposits in natural containers. scale patterns correlate with cuticle ... | 2016 | 27105225 |
| oral receptivity of aedes aegypti from cape verde for yellow fever, dengue, and chikungunya viruses. | at the end of 2009, 21,313 cases of dengue-3 virus (denv-3) were reported in the islands of cape verde, an archipelago located in the atlantic ocean 570 km from the coast of western africa. it was the first dengue outbreak ever reported in cape verde. mosquitoes collected in july 2010 in the city of praia, on the island of santiago, were identified morphologically as aedes aegypti formosus. using experimental oral infections, we found that this vector showed a moderate ability to transmit the ep ... | 2013 | 23199267 |
| 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 |
| susceptibility profile of aedes aegypti l. (diptera: culicidae) from montclair, california, to commonly used pesticides, with note on resistance to pyriproxyfen. | the peridomestic anthropophilic aedes aegypti l. (diptera: culicidae) is originated from the wild zoophilic subspecies aedes aegypti formosus in sub-saharan africa, and currently has a broad distribution in human-modified environments of the tropics and subtropics worldwide. in california, breeding populations were initially detected in 2013 in the cities of fresno, madera, and san mateo, and now can be found in 188 cities of 12 counties in the state. recent genetic studies suggest that this spe ... | 2019 | 30810751 |
