a survey of the distribution and relative prevalence of aedes aegypti in sabah, brunei, and sarawak.although dengue haemorrhagic fever is widely established in south-east asia, no cases have been reported from borneo. in order to help to assess whether the infection could become established in borneo, a survey was made, using the single-larva collection method, of the distribution and prevalence of the principal vector, aedes aegypti, in sabah and in a few towns and villages of brunei and sarawak. in addition, the prevalence of ae. aegypti was compared with that of certain other species of aed ...19724537482
studies on the life budget of aedes aegypti in wat samphaya, bangkok, thailand.for a complete understanding of the epidemiology of a vector-borne disease, a knowledge of the bionomics of the vector is needed. the development of aedes aegypti was studied in wat samphaya, bangkok, thailand, where work on the adult biology had been carried out the previous year (1966-67). particular attention was given to the variation in the numbers of immature stages of the mosquito in relation to the known seasonal incidence of dengue haemorrhagic fever. of the three types of water contain ...19724537483

breeding of aedes aegypti and a. simpsoni under the escarpment of the tanzanian plateau.villages under the escarpment of the tanzanian plateau were surveyed for breeding of aedes aegypti. in some places more than 27% of the water containers outside houses harboured a. aegypti larvae, while there was practically no breeding in containers inside houses. from 2% to 10% of tree holes contained a. aegypti larvae. in places, as many as 47 a. simpsoni larvae were collected from one pineapple plant, and the total mean number of larvae per pineapple was 6.6, while the percentage of plants w ...19724538907
seasonal changes in the larval populations of aedes aegypti in two biotopes in dar es salaam, tanzania.the seasonal dynamics of larval populations of aedes aegypti was studied in two different biotopes in dar es salaam, tanzania. the first biotope was located on the msasani peninsula on the coast 6 km north of dar es salaam, where a. aegypti breeds exclusively in coral rock holes. the population dynamics was studied during both the rainy and the dry season. seasonal changes in the density of a. aegypti larvae depend primarily on variation in rainfall. the population of larvae dropped to zero only ...19724539415
dry season survival of aedes aegypti eggs in various breeding sites in the dar es salaam area, tanzania.in field experiments in different breeding sites in a shaded suburban area, 7-40% of a. aegypti eggs survived a 120-day dry period. in a relatively unshaded coral area, only 3-23% of eggs survived 60 days in exposed sites, but 7-17% survived 120 days in shaded sites. survival in some sites was higher than in the laboratory at constant conditions.19724539825
host preferences of various strains of aedes aegypti and a. simpsoni as determined by an olfactometer.the author describes and illustrates a new type of olfactometer that can be used to determine the host preference of different strains of stegomyia mosquitos. experiments with human and animal hosts in tanzania showed that dark strains of a. aegypti are much less anthropophilic than light strains.19724540689

aedes aegypti (l.) and aedes albopictus (skuse) in singapore city. 1. distribution and density.the distribution and density of ae. aegypti and ae. albopictus in singapore were assessed from extensive larval surveys carried out from 1966 to 1968 to evaluate their respective roles in the epidemiology of dengue haemorrhagic fever and to study their ecology in the urban areas. ten urban areas where the majority of dengue haemorrhagic fever cases occurred were surveyed.the results showed that both species were common in the city, with ae. aegypti being the dominant species. the distribution of ...19715316745
aedes aegypti (l.) and aedes albopictus (skuse) in singapore city. 2. larval habitats.detailed information on the breeding habitats of ae. aegypti and ae. albopictus is necessary when planning programmes for their control. the larval habitats of the two species in 10 city areas were counted and classified according to type, frequency of occurrence, location, and function. of all the breeding habitats recorded 95% were domestic containers. the most common ae. aegypti breeding habitats were ant traps, earthenware jars, bowls, tanks, tin cans, and drums, ant traps being the most com ...19715316746
aedes aegypti (l.) and aedes albopictus (skuse) in singapore city. 3. population fluctuations.fluctuations in the adult ae. aegypti and ae. albopictus populations and their relationship to rainfall were studied by weekly collections from a number of stations in the city. aedes aegypti populations generally fluctuated with the rainfall, with multiple peaks, except in the middle of the year when there was no increase in rainfall at the time of the peak in population. it is suggested that other regulating factors, in addition to rainfall, also determine the fluctuations of this species. aed ...19715316747
aedes aegypti (l.) and aedes albopictus (skuse) in singapore city. 4. competition between species.there is a current belief stemming from statements made in the literature that ae. aegypti is displacing ae. albopictus in a number of cities of south-east asia and in calcutta, india. a critical review of these works showed that either the observations were inconclusive or the methods of collection were biased for one or the other species.extensive surveys of the larval habitats of the two species in singapore showed that the sharing of breeding habitats was uncommon in both urban and rural are ...19715316748
aedes aegypti (l.) and aedes albopictus (skuse) in singapore city. 5. observations in relation to dengue haemorrhagic fever.dengue haemorrhagic fever in singapore was a disease of the urban human population, with concentrations of cases occurring in areas of high population density. mosquito surveys revealed that these areas also had high population densities of ae. aegypti and ae. albopictus.the disease occurred throughout the year but the incidence of cases appeared to follow a seasonal pattern. observations from 1966 to 1968 showed that the number of cases increased in april, reached a peak in november, and, there ...19715316749
