| behavioural and insecticidal effects of organophosphate-, carbamate- and pyrethroid-treated mosquito nets against african malaria vectors. | three insecticides - the pyrethroid deltamethrin, the carbamate carbosulfan and the organophosphate chlorpyrifos-methyl - were tested on mosquito nets in experimental huts to determine their potential for introduction as malaria control measures. their behavioural effects and efficacy were examined in anopheles gambiae giles s.s. (diptera: culicidae) and anopheles funestus giles s.s. in muheza, tanzania, and in anopheles arabiensis patton and culex quinquefasciatus say in moshi, tanzania. a stan ... | 2009 | 19941597 |
| vector species composition and malaria infectivity rates in mkuzi, muheza district, north-eastern tanzania. | entomological surveys were conducted in mkuzi village in muheza district, north-east tanzania from april to september 2003. the objectives were to determine the species composition and infectivity rates of mosquitoes in mkuzi village. mosquito collection was done using cdc light trap and pyrethrum spray catch (psc) techniques. the light trap: spray catch ratio was 2.2:1. a total of 2157 mosquitoes were collected (light trap = 1483; psc = 674). anopheles gambiae s.s. accounted for 56.7% (n = 1224 ... | 2008 | 18680965 |
| comparison of carbon dioxide-baited trapping systems for sampling outdoor mosquito populations in tanzania. | for collecting mosquitoes (diptera: culicidae) the outdoor catching efficiency of four types of trapping devices baited with carbon dioxide (co2, 300 ml/ min) was evaluated and compared in two areas of tanzania. the types of traps employed were: the cdc miniature trap with the incandescent light bulb switched on or off; electric nets (ent) and a counterflow geometry (cfg) trap. in njage, southeast tanzania, anopheles gambiae giles sensu stricto was the most abundant of the seven mosquito species ... | 2000 | 11016432 |
| the effects of natural plasmodium falciparum infection on the fecundity and mortality of anopheles gambiae s. l. in north east tanzania. | rodent and avian malaria parasites have been reported to have an adverse affect upon the reproductive fitness of mosquitoes. in order to determine whether fecundity reduction occurs in anopheles gambiae s. l. infected with human malaria a study of wild-caught mosquitoes was undertaken in the muheza district of north east tanzania. fully engorged, indoor resting females were collected daily for 4 months and maintained for 5 days. a sporozoite rate of 11.5% was detected for the whole collection an ... | 1997 | 9107019 |
| the polymerase chain reaction method as a tool for identifying members of the anopheles gambiae complex (diptera:culicidae) in northeastern tanzania. | polymerase chain reaction (pcr) primers developed at the centers for disease control in atlanta for the identification of members of the anopheles (cellia) gambiae giles complex were tested on material collected in the bagamoyo and muheza districts of northeastern tanzania. part of the sample from bagamoyo was chromosomally identified and correlated with the pcr identifications. this sample contained 170 anopheles arabiensis, 328 an. gambiae, and 58 anopheles merus, of which 121, 237, and 54 spe ... | 1996 | 8827604 |
| the rise and fall of malarial sporozoite rates in anopheles gambiae s.l. and an. funestus in north-eastern tanzania, between 1934 and 1999. | the proportion of anopheles mosquitoes found to be carrying plasmodium sporozoites, usually called the 'malarial sporozoite rate', has often been used as a measure of mosquito infectivity. although the sporozoite rates found in anopheles gambiae and an. funestus in muheza, north-eastern tanzania, showed a marked decline between the mid-1930s and the mid-1970s, they then began to rise again. this fall and rise in mosquito infectivity is attributed to the widespread use of antimalarial drugs, whic ... | 2001 | 11454241 |
