| habitat stability and occurrences of malaria vector larvae in western kenya highlands. | although the occurrence of malaria vector larvae in the valleys of western kenya highlands is well documented, knowledge of larval habitats in the uphill sites is lacking. given that most inhabitants of the highlands actually dwell in the uphill regions, it is important to develop understanding of mosquito breeding habitat stability in these sites in order to determine their potential for larval control. | 2009 | 19845968 |
| male mating biology. | before sterile mass-reared mosquitoes are released in an attempt to control local populations, many facets of male mating biology need to be elucidated. large knowledge gaps exist in how both sexes meet in space and time, the correlation of male size and mating success and in which arenas matings are successful. previous failures in mosquito sterile insect technique (sit) projects have been linked to poor knowledge of local mating behaviours or the selection of deleterious phenotypes during colo ... | 2009 | 19917078 |
| land use and land cover changes and spatiotemporal dynamics of anopheline larval habitats during a four-year period in a highland community of africa. | spatial and temporal variations in the distribution of anopheline larval habitats and land use and land cover (lulc) changes can influence malaria transmission intensity. this information is important for understanding the environmental determinants of malaria transmission heterogeneity, and it is critical to the study of the effects of environmental changes on malaria transmission. in this study, we investigated the spatial and temporal variations in the distribution of anopheline larval habita ... | 2009 | 19996440 |
| habitat suitability and ecological niche profile of major malaria vectors in cameroon. | suitability of environmental conditions determines a species distribution in space and time. understanding and modelling the ecological niche of mosquito disease vectors can, therefore, be a powerful predictor of the risk of exposure to the pathogens they transmit. in africa, five anophelines are responsible for over 95% of total malaria transmission. however, detailed knowledge of the geographic distribution and ecological requirements of these species is to date still inadequate. | 2009 | 20028559 |
