Ecological plasticity to ions concentration determines genetic response and dominance of Anopheles coluzzii larvae in urban coastal habitats of Central Africa

Scientific Reports, 2021
In Central Africa, the malaria vector Anopheles coluzzii is predominant in urban and coastal habitats. However, little is known about the environmental factors that may be involved in this process.

Widespread occurrence of copy number variants and fixation of pyrethroid target site resistance in Anopheles gambiae (s.l.) from southern Côte d’Ivoire

Current Research in Parasitology and Vector-Borne Diseases, 2023
Resistance to pyrethroid and organophosphate insecticides in the malaria vector Anopheles gambiae (s.l.) is conferred by a variety of genetic mutations, including single nucleotide polymorphisms (SNPs) and copy number variants (CNVs).

Genetic Surveillance Reveals Differential Evolutionary Dynamic of Anopheles gambiae Under Contrasting Insecticidal Tools Used in Malaria Control

Molecular Ecology, Volume 35, Issue 5, March 2026.
ABSTRACT Malaria, a febrile disease caused by the Plasmodium parasites and transmitted by mosquitoes, is a leading cause of mortality in children under 5 in endemic countries. The widespread deployment of insecticide‐treated bed nets (ITNs) has significantly reduced malaria transmission, but rising levels of insecticide resistance threaten to halt the ...

Gene copy number and function of the APL1 immune factor changed during Anopheles evolution

Parasites & Vectors, 2020
Background The recent reference genome assembly and annotation of the Asian malaria vector Anopheles stephensi detected only one gene encoding the leucine-rich repeat immune factor APL1, while in the Anopheles gambiae and sibling Anopheles coluzzii, APL1

Resistance to pirimiphos-methyl in West African Anopheles is spreading via duplication and introgression of the Ace1 locus.

PLoS Genetics, 2021
Vector population control using insecticides is a key element of current strategies to prevent malaria transmission in Africa. The introduction of effective insecticides, such as the organophosphate pirimiphos-methyl, is essential to overcome the ...

PoolSeq Genome‐Wide Association Studies and Microbial Signature Analyses Identify Novel Candidates Associated With Pyrethroid Resistance Evolution in Anopheles funestus in Cameroon

Molecular Ecology, Volume 35, Issue 1, January 2026.
ABSTRACT Intensification of insecticide resistance in malaria vectors is undermining efforts to sustain control strategies. The evolutionary features underlying such exacerbation in major vector such as Anopheles funestus are only partially understood.

The origin of island populations of the African malaria mosquito, Anopheles coluzzii [PDF]

, 2020
Anopheles coluzzii is a major malaria vector throughout its distribution in west-central Africa. Here we present a whole-genome resequencing study of 77 specimens from eight localities, that covers a large part of this species’ range, including three islands in the Gulf of Guinea: Bioko, São Tomé and Príncipe ...

Species Occurrence and Seasonal Variation of Malaria Vectors in Hadiya Zone, Ethiopia

BioMed Research International, Volume 2026, Issue 1, 2026.
Environmental change can alter the species occurrence and seasonal distribution of malaria vectors to higher altitudes and latitudes. Highlands remain dynamic due to factors that favor their growth and development. Invasive species have proliferated into new ecological niches, increased.

Increasing role of Anopheles funestus and Anopheles arabiensis in malaria transmission in the Kilombero Valley, Tanzania [PDF]

, 2014
In order to sustain the gains achieved by current malaria control strategies, robust surveillance systems that monitor dynamics of vectors and their roles in malaria transmission over time are essential. This longitudinal study demonstrates the trends in

Molecular and entomological surveillance of malaria vectors in urban and rural communities of Benguela Province, Angola

Parasites & Vectors
Background Malaria is a major public health problem in Angola, with Anopheles gambiae sensu lato (s.l.) and An. funestus s.l. being the primary vectors. This study aimed to clarify the information gaps concerning local Anopheles mosquito populations. Our
