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 ...

Dual‐line Genome‐scale CRISPR Screening Enables Robust Target Gene Discovery

Advanced Science, EarlyView.
A species‐optimized CRISPR platform integrates efficient piggyBac delivery, genome‐scale sgRNA libraries, and parallel screening in two independently engineered Bactrocera dorsalis Cas9 cell lines. Cross‐line consensus analysis filters line‐specific effects, enriches candidates with reproducible in vivo phenotypes, and reveals conserved, species ...

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

Molecular identification of sibling species in the Anopheles gambiae complex using PCR in Bauchi State, Nigeria

UMYU Scientifica Journal
Malaria vector control programs in Bauchi State, Nigeria, rely on accurate identification of mosquito species. This study aimed to determine the composition of the Anopheles gambiae sibling species complex in the region. Using Pyrethroid spray collection,

Long‐term impact of exposure to Royal Guard, a pyriproxyfen‐based bed net, on pyrethroid‐resistant malaria vectors from Cameroon using DNA‐based metabolic resistance markers

Pest Management Science, Volume 81, Issue 4, Page 2165-2180, April 2025.
We used recently detected P450 DNA‐based markers of pyrethroid resistance in both Anopheles funestus and Anopheles gambiae to demonstrate that although pyrethroid‐resistant mosquitoes have higher ability to survive and live longer after exposure to Royal Guard, this net significantly affects their lifespan, blood feeding ability and interestingly ...

Decades of Enclosure Protection Exert Composite Effects on Grassland Grasshopper Communities

Integrative Zoology, EarlyView.
Decades of enclosure protection have altered grasshopper community structure, with species‐specific effects on population dynamics. For the low‐mobility grasshopper Chorthippus fallax, abundance did not differ strongly between exclosure‐protected and overgrazed areas, but its egg development duration was longer in exclosures. The two C.

Transcriptional responses of Aedes aegypti chemosensory tissues in response to volatile DEET and citronella oil

Insect Molecular Biology, EarlyView.
Aedes aegypti females were significantly repelled by both volatile DEET and citronella oil in comparison to control (ethanol‐exposed) mosquitoes. Global gene expression changes were largest in the mosquito mouthparts, with notable downregulation of the three subunits comprising the mosquito CO2 receptor (Gr1, 2 and 3).

Malaria mosquito antimicrobial defence requires immunity and detoxification gene regulation by Lola

Insect Molecular Biology, EarlyView.
Malaria mosquito antimicrobial defence requires upregulation of lola. Attenuation of lola in the midgut of Anopheles albimanus mosquitoes inhibits the upregulation of immunity genes induced by challenge. Putative target genes of the Lola transcription factor were revealed by lola attenuation, including Cecropin‐C, Draper, PPAF2, Clip‐domain serine ...
