vectors

This paper demonstrates the power of geomatic tools to quantify the spatial organization of mosquito populations, and allows a better understanding of links between landcover, breeding habitats, presence of immature mosquito populations and adult distributions for different species.

This investigation was to explore the metabolic status of GSTs in two Indian DDT-resistant malaria vectors, Anopheles culicifacies and Anopheles annularis, and one DDT-susceptible vector, Anopheles fluviatilis. Malkangiri and Koraput districts of Orissa State, endemic for falciparum malaria and having a long insecticide spraying history, were the study areas.

We developed a multiplex polymerase chain reaction (PCR)–based assay specific for known species-specific nucleotide differences in the internal transcribed spacer 2 region and identified the five species most frequently implicated in transmitting disease (An. punctulatus, An. koliensis, An. farauti 1, An. hinesorum, and An. farauti 4).

The social acceptability and durability of two house screening interventions were addressed using focus group discussions, questionnaires, indoor climate measurements, and durability surveys.

We optimized an antigenic insert comprising the four conserved blocks of MSP-1 fused to tandemly arranged sequences that represent both allelic forms of the dimorphic 42-kDa C-terminal region.

From October 2002 to September 2003, an entomological survey was carried out in a rural forested fringed village in the highlands of Mount Cameroon region to determine the temporal dynamics of the anopheline population and the intensity of malaria transmission.

These findings suggest that ivermectin MDA in Africa may be used to decrease malaria transmission if MDAs were administered more frequently.

A verandah trap experimental hut trial of ITPS with or without Olyset LN was conducted in the Vallee du Kou near Bobo-Dioulasso, where the two molecular forms of Anopheles gambiae s.s., S (frequency 65%) and M (frequency 35%), occur.

Multilocus molecular phylogenetic study of Indian anophelines and An. gambiae was conducted at each individual genetic region using Neighbour Joining (NJ), Maximum Likelihood (ML), Maximum Parsimony (MP) and Bayesian approaches.

In this study, we report further on the accuracy of this tool for simultaneously estimating the age class and differentiating the morphologically indistinguishable An. gambiae s.s. and An. arabiensis from semi-field releases and wild populations.
