Dynamics of gene introgression in the African malaria vector Anopheles gambiae. [PDF]

, 2006
Anopheles gambiae is a major malaria vector in Africa and a popular model species for a variety of ecological, evolutionary, and genetic studies on vector control.

Full‐length coding sequence analysis of the voltage‐gated sodium channel and acetylcholinesterase genes reveals target‐site mutations and acetylcholinesterase gene duplication in housefly (Musca domestica) populations in Japanese livestock barns

Medical and Veterinary Entomology, EarlyView.
We simultaneously analysed insecticide resistance mutations in VGSC and AChE using NGS and hybridization probe capture in houseflies collected from livestock facilities for the first time. Resistance mutations in both VGSC and AChE were detected in most wild populations, suggesting widespread distribution of resistance genes.

Host-specific cues cause differential attractiveness of Kenyan men to the African malaria vector Anopheles gambiae [PDF]

, 2002
Background Many studies have suggested that variability in the attractiveness of humans to host-seeking mosquitoes is caused by differences in the make-up of body emanations, and olfactory signals in particular.

Indoor residual spraying of distinct insecticide formulations in a household‐scale micro‐mosaic format: Feasibility and effectiveness for malaria vector control in rural Zambia

Medical and Veterinary Entomology, EarlyView.
Densities of all Anopheles species were approximately comparable across all IRS regimes. No differences observed between treatment regimes regarding species composition of the Anopheles funestus group or An. gambiae complex. This operational pilot demonstrates the practical feasibility of IRS micro‐mosaics, despite the inherent increase in deployment ...

Relationship between the L1014F mutation in the kdr gene and the endophagic and exophagic behaviors of Anopheles coluzzii and Anopheles gambiae in Benin

Journal of Basic and Applied Zoology
Background The increasing resistance exhibited by Anopheles gambiae and Anopheles coluzzii to insecticides represents a major challenge for malaria vector control strategies. This study aimed to investigate the relationship between the L1014F mutation in

Proportional decline of Anopheles quadriannulatus and increased contribution of An. arabiensis to the An. gambiae complex following introduction of indoor residual spraying with pirimiphos-methyl: an observational, retrospective secondary analysis of pre-existing data from south-east Zambia

Parasites & Vectors, 2018
Background Across most of sub-Saharan Africa, malaria is transmitted by mosquitoes from the Anopheles gambiae complex, comprising seven morphologically indistinguishable but behaviourally-diverse sibling species with ecologically-distinct environmental ...

Effects of Asaia spp. on the development, size and associated microbiomes of two mosquito species of medical importance

Medical and Veterinary Entomology, EarlyView.
Addition of Asaia species to the rearing water of mosquito larvae can affect the structure of the larval microbiome, although these bacteria do not persist to the pupal stage. Asaia inoculation can increase the adult size of males of two mosquito species. The impact of Asaia inoculation on development rate and female size depended on bacterial and host

Near-infrared spectroscopy as a complementary age grading and species identification tool for African malaria vectors. [PDF]

, 2010
: Near-infrared spectroscopy (NIRS) was recently applied to age-grade and differentiate laboratory reared Anopheles gambiae sensu strico and Anopheles arabiensis sibling species of Anopheles gambiae sensu lato complex. In this study, we report further on

Evolution of the Ace-1 and Gste2 Mutations and Their Potential Impact on the Use of Carbamate and Organophosphates in IRS for Controlling Anopheles gambiae s.l., the Major Malaria Mosquito in Senegal

Pathogens, 2022
Widespread of insecticide resistance amongst the species of the Anopheles gambiae complex continues to threaten vector control in Senegal. In this study, we investigated the presence and evolution of the Ace-1 and Gste2 resistance genes in natural ...
