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).

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.

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 ...

Larvicidal and Ovicidal Effects of Methanol Extracts From Selected Ethiopian Medicinal Plants Against Anopheles arabiensis and Aedes aegypti

Journal of Tropical Medicine, Volume 2026, Issue 1, 2026.
Background Synthetic insecticides face challenges, such as resistance, environmental damage, and harm to nontarget species, highlighting the need for alternative methods. Medicinal plants, along with their bioactive compounds, offer a promising solution. Objective This study investigated the efficacy of methanol extracts derived from traditionally used

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

Genetics and immunity of Anopheles response to the entomopathogenic fungus Metarhizium anisopliae overlap with immunity to Plasmodium

Scientific Reports, 2022
Entomopathogenic fungi have been explored as a potential biopesticide to counteract the insecticide resistance issue in mosquitoes. However, little is known about the possibility that genetic resistance to fungal biopesticides could evolve in mosquito ...

Must Epidemiologically Impactful Vector Control Interventions Disrupt Mosquito Population Structure? A Case Study of a Cluster‐Randomised Controlled Trial

Evolutionary Applications, Volume 18, Issue 11, November 2025.
ABSTRACT Large epidemiological impacts resulting from disease vector control interventions are typically associated with significant disruption of vector populations. While vector density is a frequently measured response, impacts on demography and connectivity are suspected but rarely quantified.

Climate Change Favors African Malaria Vector Mosquitoes

Global Change Biology, Volume 31, Issue 11, November 2025.
Malaria is a deadly parasitic disease that is transmitted by mosquitoes. This study investigates occurrence patterns of malaria mosquito species to predict how climate change will affect their range in sub‐Saharan African, where most malaria deaths occur.

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
