| estimation of survival rate and oviposition interval of anopheles balabacensis mosquitoes from mark-recapture experiments in sabah, malaysia. | an exophilic population of the vector mosquito anopheles balabacensis baisas was investigated in two mark-recapture studies (16.ix-13.x.1986 and 6-26.i.1987) at an inland, foothill village in sabah, malaysia. wild female mosquitoes were intercepted as they came to feed on man or buffalo, given a bloodmeal, marked with fluorescent dust and released. the recapture rate was about 12%. a new method of analysis is proposed which uses cross-correlation and a time series model. the estimated survival p ... | 1990 | 2132976 |

| transmission dynamics and estimates of malaria vectorial capacity for anopheles balabacensis and an. flavirostris (diptera: culicidae) on banggi island, sabah, malaysia. | holoendemic malaria transmission in two small isolated forest communities and a coastal village was studied by (1) all night human bait collections of anopheles species from inside and outside houses and (2) buffalo-biting and cdc light-trapping catches during march and november 1984. during the same period thick and thin blood films were collected from the human population, and spleen rates were determined in children from two to nine years of age. using both the immunoradiometric assay (irma) ... | 1988 | 3041932 |
| responses of anopheles balabacensis to various patterns of ddt-spraying of shelters in sabah, east malaysia. | 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 mad ... | 1968 | 5302337 |
