The study aimed to evaluate the susceptibility of Anopheles species to DDT 4% and deltamethrin 0.05%. Mosquitoes were tested for their susceptibility to both insecticides following WHO standards and using test kit provided by WHO. The study indicated that Anopheles mosquito was found tolerant to DDT 4% and deltamethrin 0.05% in Juba County in all mosquitoes collected from the sentinel sites. Ho...
We explored the use of the European Remote Sensing Satellite 2 Synthetic Aperture Radar (ERS-2 SAR) to trace the development of rice plants in an irrigated area near Niono, Mali and relate that to the density of anopheline mosquitoes, especially An. gambiae. This is important because such mosquitoes are the major vectors of malaria in sub-Saharan Africa, and their development is often coupled t...
Natural anopheline populations exhibit much variation in ability to support malaria parasite development, but the genetic mechanisms underlying this variation are not clear. Previous studies in Mali, West Africa, identified two quantitative trait loci (QTL) in Anopheles gambiae mosquitoes that confer refractoriness (failure of oocyst development in mosquito midguts) to natural Plasmodium falcip...
Entomologists often require large numbers of experimental insects for laboratory studies. The quality of these insects should be high and constant, otherwise the results of replicate experiments can be contradictive or results from subsequent fieldwork might be disappointing. The quality of experimental insects can be influenced by population density, nutrition, environmental conditions, etc. T...
Salivary gland proteins of Anopheles mosquitoes offer attractive targets to understand interactions with sporozoites, blood feeding behavior, homeostasis, and immunological evaluation of malaria vectors and parasite interactions. To date limited studies have been carried out to elucidate salivary proteins of An. stephensi salivary glands. The aim of the present study was to provide detailed ana...
Re-examination, using molecular tools, of the diversity of haemosporidian parasites (among which the agents of human malaria are the best known) has generally led to rearrangements of traditional classifications. In this study, we explored the diversity of haemosporidian parasites infecting vertebrate species (particularly mammals, birds and reptiles) living in the forests of Gabon (Central Afr...
susceptibility levels of a lab strain of an. stephensi to who standard papers of ddt 4%, dieldrin 0.4%, malathion 5%, permethrin 0.25%, lambdacyhalothrin 0.1%, cyfluthrin 0.1% and deltamethrin 0.025% were determined in our laboratory in 1999. results showed that at the diagnostic dose of insecticides this species exhibited resistance to ddt and dieldrin with mortality rate of 54±2.5% and 30±2.5...
Malaria transmission remains poorly documented in areas of low transmission. A study has been carried out over two consecutive years in Analamiranga, a village located at an altitude of 885m on the western edge of the Malagasy highlands, with the aim of generating and updating malariometric indexes for both mosquitoes and schoolchildren. In this village, no vector control measures were performe...
