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 ...

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 ...

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 ...

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

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 Insights and Repellent Efficacy of the Essential Oil and Major Compounds From Piper cyrtopodon (Miq.) C.DC (Piperaceae) Against Aedes aegypti (Linnaeus, 1762) (Culicidae)

Archiv der Pharmazie, Volume 359, Issue 6, June 2026.
The essential oil and major compounds from Piper cyrtopodon exhibit potent, long‐lasting repellent activity against Aedes aegypti mosquitoes, combined with low cytotoxicity and favorable molecular docking interactions with odorant‐binding proteins. These findings highlight its potential for the development of alternative products for bite prevention ...

Trends in the selection of insecticide resistance in Anopheles gambiae s.l. mosquitoes in northwest Tanzania during a community randomized trial of longlasting insecticidal nets and indoor residual spraying. [PDF]

, 2014
Anopheles gambiae s.l. (Diptera: Culicidae) in Muleba, Tanzania has developed high levels of resistance to most insecticides currently advocated for malaria control. The kdr mutation has almost reached fixation in An. gambiae s.s. in Muleba.

Exploring marking methods for the predatory hoverfly Sphaerophoria rueppellii (Diptera: Syrphidae)

Insect Science, Volume 33, Issue 3, Page 1109-1122, June 2026.
As important pollinators and predators of aphids, hoverflies play an important role in ecosystems. This study focuses on identifying the best marking technique for the model species Sphaerophoria rueppellii that can be used to track hoverfly feeding and oviposition sites, evaluating three methods: rubidium (RbCl), fluorescein, and fluorescent dusts ...

Beyond Temperature: Relative Humidity Systematically Shifts Juvenile Thermal Performance and Projected Population Growth in a Malaria Vector

Ecology Letters, Volume 29, Issue 6, June 2026.
Understanding how ectotherms respond to environmental change requires accounting for multiple interacting climatic factors; yet relative humidity is rarely integrated with temperature in trait‐based performance frameworks. Using laboratory experiments and an analytic population growth model, we show that humidity systematically modifies juvenile life ...
