Indoor and outdoor malaria vector surveillance in western Kenya: implications for better understanding of residual transmission

Malaria Journal, 2017
Background The widespread use of indoor-based malaria vector control interventions has been shown to alter the behaviour of vectors in Africa. There is an increasing concern that such changes could sustain residual transmission.

Population Structure of Anopheles gambiae in Africa [PDF]

Journal of Heredity, 2003
The population structure of Anopheles gambiae in Africa was studied using 11 microsatellite loci in 16 samples from 10 countries. All loci are located outside polymorphic inversions. Heterogeneity among loci was detected and two putative outlier loci were removed from analyses aimed at capturing genome-wide patterns. Two main divisions of the gene pool

Anopheline species composition and the 1014F-genotype in different ecological settings of Burkina Faso in relation to malaria transmission

Malaria Journal, 2019
Background A three-year longitudinal study was conducted in four sentinel sites from different ecological settings in Burkina Faso, between 2008 and 2010 to identify longitudinal changes in insecticide resistance within Anopheles gambiae complex species ...

Ovipositional Behavior of Anopheles gambiae Mosquitoes

Tropical Medicine and Health, 2014
Mosquito eggs laid within two hours are necessary for transgenic (injection) studies, because mosquito eggs become hard after that period. Thus, in order to have eggs available within this two-hour window, it is important to understand the ovipositional behavior of Anopheles gambiae s.s.. In the present study, the ovipositional behavior of An.

Changes in contributions of different Anopheles vector species to malaria transmission in east and southern Africa from 2000 to 2022

Parasites & Vectors, 2023
Background Malaria transmission in Africa is facilitated by multiple species of Anopheles mosquitoes. These vectors have different behaviors and vectorial capacities and are affected differently by vector control interventions, such as insecticide ...
