malaria transmission and vector biology on sainte marie island, madagascar.	a 17-mo longitudinal malaria survey (november 1988-march 1990) was carried out on sainte marie island, an area on the east coast of madagascar which is frequently visited by tourists. during 706 man-nights of capture, 46,401 mosquitoes belonging to 32 species were caught. sporozoite rates were determined by elisa and incriminated anopheles gambiae giles s.s., an. funestus giles, and an. mascarensis de meillon as vectors of malaria. an. gambiae, the main vector, was highly anthropophilic but larg ...	1992	1495029
[longitudinal study on malaria transmission and biology of vectors in the island of sainte marie, on the east coast of madagascar, from 1988 to 1990].	a 17-month longitudinal malaria survey was carried out in sainte marie island, on the east coast of madagascar, from november 1988 to march 1990. during 706 man-nights of captures, 46401 mosquitoes belonging to 32 species were caught. sporozoïte rates were calculated by elisa. the malaria vectors were anopheles gambiae sensu stricto, an. funestus and an. mascarensis. an. gambiae was the main vector. it was highly anthropophilic and partially exophilic. transmission by this species mainly occurre ...	1991	1688287
transmission and epidemiology of newly transmitted falciparum malaria in the central highland plateaux of madagascar.	the recent reappearance of plasmodium falciparum in the central highland plateaux of madagascar has led to an important increase in both morbidity and mortality in the population. to understand the phenomena that originated this outbreak, and to evaluate the clinical and biological reactions of the population, we conducted entomological surveys during the whole malaria transmission season of 1988. in parallel, 41 individuals presenting with a malaria attack in january were given a curative antim ...	1991	1746977
[antibody levels against circumsporozoitic protein of plasmodium falciparum and their use as epidemiological indicators of malaria transmission in fir of comoros].	epidemiological survey on prevalence of plasmodium falciparum anti-circumsporozoite antibodies (ab-cs) was carried out in 21 villages of comoros fir, at the beginning of 1988 rainy season. evaluation of anopheline indoor resting densities was also carried out at the same time. frequencies of antibody-positive subjects vary considerably in the different villages, according to the anopheles gambiae and a. funestus densities per room, which are determined by ecological factors. ab-cs prevalence var ...	1991	1789679
[impact of the use of larvivorous fish poecilia reticulata on the transmission of malaria in fir of comoros].	field tests were conducted in the grande comore island, federal islamic republic of comoros, in order to evaluate the potential of the larvivorous fish poecilia reticulata for the control of the malaria vector anopheles gambiae s.s. due to the high permeability of soil, anopheles breeding sites in all island occurs only in the man-made water reservoirs. the study was carried out from november 1987 to november 1988 within a framework of a malaria and filariasis control programme, supported by who ...	1991	1952700
[the maintenance of malaria eradication in reunion island (1979-1990)].	malaria, which first occurred in reunion in 1868, was eradicated from the island in 1979, as a result of eradication campaigns conducted since 1949. reunion is now in a state of "anophelism without malaria". however, relations with nearby countries with a high malaria potential (madagascar, comoros) are responsible for a regular increase in the number of annual cases of imported malaria. this increase, associated with the appearance of chloroquine-resistance in the indian ocean area, illustrates ...	1991	1958106
the anopheles gambiae complex in the federal islamic republic of comoros (indian ocean): some cytogenetic and biometric data.	samples of adult females of the anopheles gambiae complex from thirteen localities of three islands of the comoro archipelago (anjouan, grande comore and moheli) were identified by analysis of ovarian polytene chromosomes as an. gambiae s.s. the samples showed only the inversion polymorphism 2la, the mean frequency of the inverted arrangement being 38%. a significantly higher frequency of the inverted arrangement 2la was observed in the localities with a lower annual rainfall. similarities betwe ...	1990	2132451

[epidemiological malaria surveillance in 3 villages of the madagascar highlands].	results of the epidemiological surveillance of falciparum malaria carried out since 1987 in three villages of the malagasy highlands are reported. they clearly show the unsteady endemo-epidemic characteristic of the disease with highly variable transmission levels according to foci. at manarintsoa, a south-western village 20km away from the capital, the disease has now fully disappeared after the ravage of 1986. but it might reappear with new imported cases and by lack of antivectorial measures. ...	1993	8192540
[malaria in mayotte: past, present and future].	discovered as a form of intermittent fevers in 1852 and confirmed by blin in 1905, malaria has had a large impact on the mortality and the morbidity of the population living in mayotte until 1976. an evolutionary analysis of the disease shows two distinct periods. the first period between 1792 and 1974 concerns the date of introduction of malaria to the island and the limited actions of the fight against malaria led by different organizations. the second period from 1976, when the program was es ...	1995	8784540
[epidemiology and control of malaria in the federal islamic republic of comoros].	malaria constitutes a major public health problem in the federal islamic republic of comoros. this problem is relatively recent from the historical point of view of the archipelago. it represents 15 to 30% of the hospitalization cases and 15 to 20% of the registered deaths in the pediatric services. the epidemiological data collected show that the characteristics of malaria transmission continue for the stable type; however, the epidemiological situation varies from one island to another. the pr ...	1995	8784541
[control of malaria re-emergence in reunion].	réunion is currently posed with the operational problem of the last phase of the struggle against malaria, that is the consolidation and the maintenance of the state of cradication. the native parasite was eliminated, but the risk of resurgence of malaria remains on the island. this risk is even increasing from year to year because of the following: 1) the regular increase of the number of travellers originating from countries with malaria and consequently, the increase in the number of imported ...	1995	8784548
[role of culex quinquefasciatus in the transmission of bancroftian filariasis in the federal islamic republic of comoros (indian ocean)].	in october 1988-january 1989, as a part of a malaria and filariasis control programme in federal islamic republic of comoros an entomological survey was carried out in 19 rural and urban localities of grande comore. anjouan and moheli islands. the potential breeding places were examined and pyrethrum spray catches were made to evaluate the indoor resting densities of mosquitos. a total of 14.578 adult mosquitos potential vectors of filariasis was collected: 94.5% culex quinquefasciatus, 3.5% ano ...	1994	9235195
[anopheles mascarensis (de meillon, 1947): main vector of malaria in the region of fort-dauphin (south-east of madagascar)].	anopheles funestus and anopheles gambiae s.l. have been considered until now the major vectors of malaria everywhere in madagascar. anopheles mascarensis, a mosquito native to madagascar, has been identified in sainte-marie island as a secondary vector only. in 1997, an entomological study was carried out to identify the malaria vectors in the area of fort-dauphin, south-east of madagascar. every month, mosquitoes were collected from landing catches on human volunteers (from 7:00 am to 5:00 pm i ...	1999	10399606
[chromosomal polymorphism of populations of anopheles arabiensis (diptera: culicidae) from reunion island and cross-fertility among continental african populations].	cytological examination of a sample of anopheles gambiae complex mosquitoes from reunion island revealed the presence of an. arabiensis only. chromosomal polymorphisms were observed only for inversion 3ra, the standard homozygote form being predominant. cross-mating experiments with laboratory specimens originating from continental africa produced viable and fertile offspring with no chromosomal asynapsis observed in the f1 female progeny. there was no evidence for speciation of the reunion isla ...	2001	11921546
[role of anopheles funestus in the transmission of malaria in the south of madagascar (ampanihy district)].	the authors reported the results of paludometric and entomological studies carried-out for two years: 1995-1996 in two localities: ampanihy and ankilimivory located in the south of madagascar. these studies followed a suspect malaria epidemic in ankilimivory in june and july 1994; the population plasmodic index was of 45%. in april 1995, this data was of 35% in ampanihy and of 15% in ankilimivory. entomological studies carried out in april 1996 allowed to find anopheles funestus in ankilimivory ...	1996	12463008
[insecticide sensitivity in malaria vectors in high altitude madagascar after five years of vector control].	in 1991, anopheles gambiae and anopheles funestus, the main malaria vectors in the highlands of madagascar, were reported to be fully susceptible to ddt; nevertheless a slight decrease in the susceptibility levels was recorded when compared with previous assays carried out in 1962. from 1993 to 1997, five cycles of indoor residual spraying have been carried out in the highlands: a total of 1,482,000 kg of 70% wp ddt have been used for the treatment of houses and animal shelters. from 1996 to 199 ...	2000	12463031
[malaria study in the cyclone risk zone: entomological , diagnostic and therapeutic approach in the southeastern region of madagascar].	madagascar is a tropical island affected by many natural disasters. the eastern coastal zone--an area of perennial malaria transmission--is regularly exposed to cyclones. few malaria studies have been done in this area of madagascar, and none have examined the potential relationship between malaria and natural disasters. a mobile team spent six weeks in the fields doing three lines of research: an entomological study by catching mosquitoes and determining their species: a therapeutic study of ch ...	2002	12643099
"saltwater anopheles gambiae" on mauritius.	in this paper the author reports the results of three months' study of the saltwater-breeding member of the anopheles gambiae complex of sibling species on mauritius.there is evidence for the views that this form's distribution on the island is limited by the availability of suitable breeding areas, that it does not usually disperse far from the breeding grounds or coast, and that it is probably not an important vector except, perhaps, in the near vicinity of its breeding places.some new evidenc ...	1964	14278002
[molecular characterization of mosquitoes of the anopheles gambiae complex from mayotte and great comoro].	the mosquitoes of the anopheles gambiae complex have been characterised at specific and sub-specific levels in two islands of the comoros archipelago: the island of mayotte (french departmental collectivity) and the island of grande comore (comoros union). results are similar in the two islands and are presented together. the species an. gambiae s.s. was observed alone (determination performed on 149 specimens by pcr product of igs of rdna). the molecular form observed alone was s, and correspon ...	2003	14535168
methodological problems and amendments to demonstrate effects of temperature on the epidemiology of malaria. a new perspective on the highland epidemics in madagascar, 1972-89.	there is a growing consensus that changes in climate will have major consequences for human health through a reduction in the availability of food and an increasing frequency of natural disasters. however, the contribution of higher temperatures to vector-borne diseases, particularly malaria, remains controversial despite the known biological dependence of both vector and pathogen on climate. misconceptions and inappropriate use of variables and methods have contributed to the controversy. at pr ...	2003	14584363
malaria transmission in southern madagascar: influence of the environment and hydro-agricultural works in sub-arid and humid regions. part 1. entomological investigations.	a 4-year entomological study was carried out in southern madagascar to identify malaria vectors, evaluate the transmission and compare the influence of irrigation in the sub-arid and adjacent humid regions. three villages were involved in this entomological survey: androvasoa (located in the natural sub-arid ecosystem), pépiniére (sited at the centre of an irrigated rice scheme in the sub-arid region) and esana (bordered with rice fields in the humid region). mosquitoes were collected inside and ...	2004	14732241
population structure of anopheles arabiensis on la réunion island, indian ocean.	anopheles arabiensis, together with anopheles gambiae sensu stricto, are the most important vectors of human malaria in sub-saharan africa. the malaria situation keeps worsening, with 1 to 3 million deaths a year, and alternative strategies are needed to decrease malaria transmission intensity. in this paper, we studied the population structure of an. arabiensis from three sample sites on the remote indian ocean island of la réunion. our results showed strong genetic structuring between an. arab ...	2005	16354815
re-emergence of anopheles funestus and its possible effect on malaria transmission on mayotte island, indian ocean.	malaria constitutes a major public health problem on mayotte island, with the major vector being anopheles gambiae s.s. the seeming disappearance of an. funestus, the 2nd vector on the island, was observed 15 years ago. now, the presence of an. funestus during the biting collections performed in november and december 2004 confirms the re-emergence of this vector, which plays an important role in malaria transmission with an. gambiae.	2005	16506577
molecular characterization of the malaria vector anopheles gambiae s.s. in madagascar.	anopheles gambiae s.s. giles (diptera: culicidae), the primary african malaria vector, has been characterized at the subspecies level in madagascar, where only the molecular form s and haplotype gia occur. the haplotype gic proposed by other authors was not observed amongst the 35 mosquito genomes sequenced. these s/gia characteristics are also found on the comoros archipelago and in continental africa.	2006	16871703
anthropophilic mosquitoes and malaria transmission in the eastern foothills of the central highlands of madagascar.	malaria remains a major public health problem in madagascar, as it is the first cause of morbidity in health care facilities. its transmission remains poorly documented. an entomological study was carried out over 1 year (october 2003-september 2004) in saharevo, a village located at an altitude of 900m on the eastern edge of the malagasy central highlands. mosquitoes were sampled weekly upon landing on human volunteers and in various resting-places. out of 5515 mosquitoes collected on humans, 3 ...	2010	20804715
why are anopheline mosquitoes not present in the seychelles?	species of anopheline mosquitoes are largely distributed over emerged lands around the world and, within the tropics, few areas are without these insects, which are vectors of malaria parasites. among the exceptions is the seychelles archipelago in the western indian ocean. however, in the aldabra island group, located in the extreme western portion of the archipelago, anopheles gambiae s.l. was introduced, leading to massive proliferation and then elimination, with the most recent autochthonous ...	2011	21303530
