Significance Malaria control in Africa largely relies on the use of insecticides to prevent mosquitoes from transmitting malaria parasite humans; however, these have evolved resistance insecticides. To manage this threat control, it is vital that we map locations where prevalence exceeds thresholds defined by insecticide management plans. A geospatial model and data are used predict linked specific recommended actions exceeded. This shown provide more accurate next-year predictions than two...
Insecticide resistance of Anopheles gambiae (s.l.) against public health insecticides is increasingly reported in Ghana and need to be closely monitored. This study investigated the intensity insecticide An. found a vegetable growing area Accra, Ghana, where insecticides, herbicides fertilizers are massively used for plant protection. The bioefficacy long-lasting insecticidal nets (LLINs) currently distributed country was also assessed delimitate impact on effectiveness those nets.Three-...
Baseline information that is essential for determining the areas to target with larval control includes estimates of vector diversity and habitat preferences. Due a lack such in Baringo County, Kenya, this study assessed species preference potential mosquito vectors Rift Valley fever (RVF) malaria.Mosquito larvae were sampled from nine types habitats identified morphologically. Species was estimated by Shannon's index while RVF malaria determined ANOVA.A total 7724 immature mosquitoes...
<title>Abstract</title> This study analyzes the distribution, genetic diversity, and spread of <italic>An. stephensi</italic> in Kenya following initial detection December 2022. A total 114 larval 33 adult samples were confirmed 7 18 surveyed counties majorly along transportation routes. Genetic analyses revealed three distinct compositions with different levels suggesting multiple introductions into country. The composition mosquitoes most resembled southern Ethiopian populations, while...
Abstract Malaria vector control may be compromised by resistance to insecticides in populations. Actions mitigate against rely on surveillance using standard susceptibility tests, but there are large gaps the monitoring data. Using a published geostatistical ensemble model, we have generated maps that bridge these and consider likelihood exceeds recommended thresholds. Our results show this model provides more accurate next-year predictions than two simpler approaches. We used generate...
