| anopheles vestitipennis, the probable vector of plasmodium vivax in the lacandon forest of chiapas, méxico. | baseline studies to evaluate the role of different anopheline mosquitoes as probable vectors of malaria in the lacandon rainforest region in chiapas (méxico) were carried out in 3 rural villages between june and november 1988. anopheles vestitipennis was the most abundant species in all the villages, followed by an. albimanus, an. punctimacula and an. darlingi. human bait collections showed that an. vestitipennis and an. albimanus tended to bite man either indoors or outdoors, while an. punctima ... | 1991 | 1887463 |

| effects of transmission-blocking immunity on plasmodium vivax infections in anopheles albimanus populations. | two colonized populations of anopheles albimanus isolated from the suchiate region, chiapas state, mexico, were compared for their susceptibility to coindigenous plasmodium vivax. groups of mosquitoes were fed in vitro with either autologous donor blood or the same blood cells substituted with serum negative for anti-gametocyte antibody. significant differences in susceptibility between the 2 colonies were encountered if the autologous blood from a patient was fed to mosquitoes: mean infection r ... | 1994 | 8308663 |
| plasmodium vivax sporozoite rates from anopheles albimanus in southern chiapas, mexico. | anopheles albimanus mosquitoes were collected from august 1984 to november 1987 on intra- and peridomicile human bait in rancheria el gancho, chiapas, mexico. the mosquitoes were desiccated and stored in silicon chambers from 3 mo to 3 yr post-collection prior to being assayed using a direct enzyme-linked immunosorbent assay to detect plasmodium vivax predominant-type sporozoite protein. peridomicile-collected mosquitoes had a 10-fold higher sporozoite rate than those collected indoors, but only ... | 1994 | 8195955 |
| field trial in chiapas, mexico, of a rapid detection method for malaria in anopheline vectors with low infection rates. | a method consisting of filtration of up to 100 macerated mosquitoes in a batch, followed by fixation with glutaraldehyde and concentration of filtrate by centrifugation has been developed to rapidly assess malaria infection in anopheline mosquitoes. determination of the presence of sporozoites is made by observation of a sample of the final filtrate with a phase microscope. the method is simple and field adaptable, essential factors for the application of any technique to large scale field opera ... | 1986 | 3513640 |
