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
