    A first experiment on malaria control in the interior of Borneo by spraying with residual insecticides is described. The work was carried out in the isolated, sparsely populated valleys of the Baram River and its tributary, the Tinjar, in northern Sarawak. The experimental area was divided into three parts: a DDT test area, where a 75% suspension of wettable powder was applied at the rate of 2 g of DDT per m(2) of surface; a BHC test area, where a 50% suspension of wettable powder was applied at the rate of 0.10 g of gamma isomer per m(2); and a check area.Entomological investigations made before the spraying operations were started showed that Anopheles leucosphyrus Dönitz, 1901 was the main malaria vector in both the test and the check areas. Out of a total of 7568 A. leucosphyrus dissected, 30 gland infections were detected-a sporozoite-rate of 0.40%. A. barbirostris was found to be a secondary vector throughout the experimental area.THE RESULTS OF INSECTICIDE SPRAYING WERE SATISFACTORY: in the DDT test area, the spleen-rate fell from 51.8% to 25.1%, and the parasite-rate from 35.6% to 1.6%, in 21 months, and a similar reduction in the rates was observed in the BHC test area. In the check area, the spleen- and parasite-rates rose during the period of observations. It is considered that if such a degree of control can be obtained in 21 months, complete eradication can be expected in the near future.Although BHC spraying proved effective, the fact that it has to be repeated every three months makes it impracticable in the interior of Sarawak, where communications are very poor and difficulties of transport very great. DDT spraying, which need only be done twice a year, is therefore to be preferred. The cost of the DDT operations-US$ 0.45 per person protected per year-is comparatively high, owing to the difficulty of communications and to the necessity for spraying not only the village "longhouses", but also the temporary shelters which the semi-nomadic people in the interior of Sarawak build each year in the rice-fields.

    In certain areas of Sabah, East Malaysia, local houses are frequently built without walls or with incomplete walls. Also, the people in these areas often refuse permission for their houses to be sprayed inside with insecticide (DDT). These special conditions are the reason for the persistence of malaria transmission under a WHO malaria eradication programme.Field trials were conducted in specially constructed huts, similar to the local houses, in which all-night collections of mosquitos were made, both those biting human baits and those resting on walls, in order to determine (1) the effectiveness of spraying DDT in houses without, or with incomplete, walls; and (2) the best way to protect people against mosquito bites with DDT-spraying where the house-owners have refused indoor spraying.The results indicate that (1) as expected, DDT-spraying inside a hut with incomplete walls is less effective than in a hut with complete walls, especially 6 months or more after spraying; (2) external spraying of walls with DDT at double the normal dose (i.e., 4 g/m(2)) greatly reduced contacts between man and mosquito and thereby limited transmission of malaria.

    A preliminary survey of Aedes aegypti was carried out in 6 areas in the state of Selangor, Malaysia. The densities of Ae. aegypti and Ae. albopictus in the areas were discussed. Results indicated that the distribution of larval habitats varied with the housing type. The most ommon indoor larval habitat in urban areas is the bathroom tank. In both urban and rural areas, outdoor preference is for the earthenware jars. Anttraps have decreased in importance as larvae breeding habitats. The accuracy of house searches can be increased by increasing the number of larvae examined per container to 5 or more. Further study is required to determine whether the findings of this survey is peculiar to the areas surveyed or is representative of the whole country, and whether there is a seasonal fluctuation in the types of preferred larval habitats.

    A breeding colony utilizing a harem mating system was established to study the feasibility of breeding cynomoglus monkeys, Macaca fascicularis, in Malaysia. Two groups consisting of 10 females and one male each were evaluated over a 3 period. Forty births were recorded; one was stillborn, 11 died while nursing, and 28 were weaned. The average time to wean offspring was 230 days with an average weight at weaning of 0.858 kg. The average time for conception to take place after weaning was 50 days. Of the 20 breeder females, six produced three offspring each, nine produced two offspring each, four produced one offspring each and one remained barren throughout the project. Three different weaning systems were evaluated. The best method was caging the mother-infant pair within or adjacent to the breeding room followed by a two-part cage system which allowed the infant to continue nursing and also obtain solid food inaccessible to the mother.

    "This article examines some of the links between the phenomena of urban migration and squatter settlements in the Third World city. This will be done by demonstrating that both are outcomes of fundamental social and political forces that have operated on these societies. Migration and squatting are placed in a context of the historical processes that led to the uneven development of Malaysia. The article offers some explanation for the origin of the inequalities observed in spatial structures--in this case urban housing--by focusing on one of the contributory factors, namely migration."

    A survey was conducted in six selected rural villages to obtain baseline data on socioeconomic status, nutrition, environmental sanitation and behavioural aspects in relation to diarrhoeal diseases, using a standard questionnaire. Subsequent to this, children 0-4 years of age were followed weekly for six months for diarrhoeal disease. Eleven variables representing socioeconomic status, nutritional status, housing condition, environmental sanitation, mother's knowledge and beliefs were investigated using stepwise logistic regression to determine significant predictors of diarrhoeal disease. Children who were below two years of age, living in conditions of poor sanitation and poor quality water supply, whose houses were prone to flooding and who had mothers whose sanitary habits were not influenced by their religious beliefs, were at significantly greater risk of diarrhoeal disease.

    In Sarawak, some tribes stay in communal longhouses whilst others live in villages of single dwellings. The present study looks into the question of whether there is an association between the prevalence of leprosy and tuberculosis with the quantum of social contact that occurs in these two types of settlement patterns. It was found that the prevalence of leprosy and tuberculosis is significantly higher among longhouse dwellers compared with single house dwellers. It was also noted that social groups tended to be larger and to persist for much longer among longhouse dwellers than among those in single dwellings. This lends support to the evidence that social contact in longhouses is more extensive and contributes towards a higher prevalence of leprosy and tuberculosis.

    Susceptibility tests were carried between 1987-1989 on Anopheles maculatus female adults collected from twelve different localities in Peninsular Malaysia to DDT. Mosquitoes collected from all localities except those from Kuala Berang, Trengganu state were found to be susceptible to DDT when tested with 4% impregnated paper. Several factors contributing to the lack of development of resistance despite many years of residual spraying in Peninsular Malaysia include exophily, exophagic and excito-repellency behaviour of An. maculatus and the inadequate spraying coverage of houses.

    Using logit techniques and data from surveys of the elderly conducted in 1984 under the auspices of the World Health Organization, this article investigates socioeconomic, cultural, and demographic determinants of living arrangements of the elderly. Having a spouse or children with whom to live has important effects on living arrangements. The results provide only weak support, however, for hypotheses based on modernization theory and point to the need for detailed data on transitions in living arrangements and for information about the younger generation as well as the older generation, both of which are involved in deciding who lives with whom.

    The focus of this study is on urbanization in Malaysia. "This paper is divided into three parts. The first part examines the trend of uneven urban development in West Malaysia. The second part discusses the change [in] ethnic composition of urban population between 1970 and 1980 intercensal period. The third part analyses the impact of the urbanization process on the Malays in the context of housing problems of the lower income groups." (SUMMARY IN THA)
