| bednets and malaria. | studies across africa have shown that insecticide-treated materials (itms) such as bednets can substantially reduce levels of child mortality through the prevention of malaria. however, while the results of efficacy trials may dictate the need to use itms, people in malaria-endemic areas may not recognize and comply with the need. if one wishes to get people to use health technology such as insecticide-impregnated bednets, one must learn about the end-users through clear, simple, formative res ... | 1998 | 12293744 |
| efficacy of bacillus sphaericus 2362 against larvae of anopheles gambiae under laboratory and field conditions in west africa. | a flowable concentrate of bacillus sphaericus (neide) strain 2362 was applied against anopheles gambiae giles s.l. mosquito larve in small plot field trials in bobo-dioulasso area. burkina-faso. third and fourth instar larvae were controlled for 10-15 days with a dosage of 10 g/m2, 3-10 days with 1 or 0.1 mg/m2, and 2 days with 0.01 g/m2. complete elimination of larval populations required 1 x 10(2) to 2 x 10(3) viable spores/ml in the larval feeding zone. after treatment, the total numbers of v ... | 1987 | 2979529 |
| beyond nature and nurture: phenotypic plasticity in blood-feeding behavior of anopheles gambiae s.s. when humans are not readily accessible. | to test for the effects of host accessibility on blood-feeding behavior, we assessed degrees of anthropophily of the malaria mosquito anopheles gambiae at two stages of the behavioral sequence of host foraging, in a rice growing area near bobo-dioulasso, burkina faso, where humans are not readily accessible because of years of generalized use of (mostly non-impregnated) bed nets. first, patterns of host selection were assessed by the identification of the blood meal origin of indoor-resting samp ... | 2009 | 19996432 |
| mixture for controlling insecticide-resistant malaria vectors. | the spread of resistance to pyrethroids in the major afrotropical malaria vectors anopheles gambiae s.s. necessitates the development of new strategies to control resistant mosquito populations. to test the efficacy of nets treated with repellent and insecticide against susceptible and insecticide-resistant an. gambiae mosquito populations, we impregnated mosquito bed nets with an insect repellent mixed with a low dose of organophosphorous insecticide and tested them in a rice-growing area near ... | 2008 | 18976553 |
