| biting behavior of anopheles mosquitoes in costa marques, rondonia, brazil. | mosquito collections were made in and near costa marques, rondonia, brazil, to determine anopheline anthropophilic/zoophilic behavior. collections from a non-illuminated, bovine-baited trap and indoor and outdoor human-bait collections were compared. anopheles darlingi and anopheles deaneorum were more anthropophilic than the other anophelines collected. the remainder of the anopheles species were collected much more frequently in bovine-baited traps than in human-bait collections. anopheles dar ... | 1991 | 1815282 |
| comparative susceptibility of anopheline mosquitoes to plasmodium falciparum in rondonia, brazil. | five anopheline species, anopheles deaneorum, an. albitarsis, an. triannulatus, an. oswaldoi, and an. mediopunctatus were compared to an. darlingi for susceptibility to infection by p. falciparum in costa marques, rondonia, brazil. laboratory reared f1 an. darlingi and anopheline test species were allowed to feed at the same time on falciparum malaria patients who had gametocytes in their blood, and who had not yet been treated with quinine. mosquitoes were dissected and examined for oocysts on ... | 1991 | 1858963 |
| colonization and maintenance of anopheles deaneorum in brazil. | anopheles deaneorum, an important malaria vector and a member of the anopheles albitarsis complex, was colonized by an artificial mating technique. morphological and behavioral differences between an. deaneorum and an. albitarsis from costa marques, rondonia, brazil, are discussed. the essential methods and colonization techniques are described. immature development and mortality rates were reduced when dried grass was added to larval rearing pans. males frequently mate more than once using the ... | 1990 | 2230782 |
| [variation of anopheles density with deltamethrin-impregnated mosquito nets in an endemic malaria area of the brazilian amazon]. | in 1992 a survey on the use of deltamethrin-impregnated mosquito nets was conducted in the municipality of costa marques, rondonia. in the intradomicile, impregnated nets decreased the vector density at rates similar to those for non-impregnated nets during low-transmission periods; during high anopheline density periods, they led to a significant reduction in vector density, while in the non-impregnated net group there was an increase in the number of anophelines captured. there was no change i ... | 1999 | 10409781 |
