The contribution of gut bacteria to insecticide resistance and the life histories of the major malaria vector Anopheles arabiensis (Diptera: Culicidae)

Scientific Reports, 2019
The gut microbiota of mosquitoes is a crucial determinant of their fitness. As such, the biology of the gut microbiota of Anopheles arabiensis, a major malaria vector of Southern Africa, was investigated. Two laboratory strains of An.

Neoclassical development of genetic sexing strains for insect pest and disease vector control

Insect Science, EarlyView.
The sterile insect technique has been effectively used for decades, and an important component is the availability of sex separation systems, in particular genetic sexing strains. Classical approaches, such as irradiation‐induced chromosomal translocations, have yielded stable strains for species like the Mediterranean fruit fly.

High entomological inoculation rate of malaria vectors in area of high coverage of interventions in southwest Ethiopia: Implication for residual malaria transmission

Parasite Epidemiology and Control, 2017
In Ethiopia, vector control is the principal strategy to reduce the burden of malaria. The entomological indicators of malaria transmission such as density, sporozoite rate and entomological inoculation rate (EIR) are parameters used to assess the impact

Second generation effects of larval metal pollutant exposure on reproduction, longevity and insecticide tolerance in the major malaria vector Anopheles arabiensis (Diptera: Culicidae)

Parasites & Vectors, 2020
Members of the Anopheles gambiae complex breed in clean, sunlit temporary bodies of water. Anthropogenic pollution is, however, altering the breeding sites of the vectors with numerous biological effects.

Shrubs and trees as natural insect protection for grazing animals in Switzerland and the alpine region: A systematic review of in vitro, in vivo and clinical trials Sträucher und Bäume als natürlicher Insektenschutz für Weidetiere in der Schweiz und im Alpenraum: Eine systematische Literaturübersicht über in vitro‐, in vivo‐ und klinische Studien

Medical and Veterinary Entomology, EarlyView.
Biting or irritating insects are a threat to the health and welfare of grazing animals. This systematic review reveals that several shrubs and bushes growing in the alpine area have insecticidal, insect‐repellent and/or attractant properties. The alder Alnus glutinosa, juniper Juniperus communis, spruce Picea abies and walnut Juglans regia are ...

Evaluation of toxicity of clothianidin (neonicotinoid) and chlorfenapyr (pyrrole) insecticides and cross-resistance to other public health insecticides in Anopheles arabiensis from Ethiopia

Malaria Journal, 2019
Insecticide-based interventions play an integral role in malaria vector control. However, the continued spread of insecticide resistance threatens to undermine progress made thus far and may ultimately lead to operational failure of current control ...

A rapid quality control test to foster the development of the sterile insect technique against Anopheles arabiensis

Malaria Journal, 2020
With the fight against malaria reportedly stalling there is an urgent demand for alternative and sustainable control measures. As the sterile insect technique (SIT) edges closer to becoming a viable complementary tool in mosquito control, it will be ...

Biochemical Responses of Anopheles spp. Larvae to a Novel Brazilian BR101 Bacillus thuringiensis var. israelensis Formulation: Oxidative Stress, Detoxification Enzymes, and Safety for Nontarget Notonectidae and Gerridae Aquatic Insects

Chemistry &Biodiversity, Volume 23, Issue 2, February 2026.
Bti BR101 exhibits strong larvicidal activity against Anopheles larvae spp., with dose‐dependent mortality and LC50 of 3.13 µg/mL. Bti increases ROS, lipid and protein oxidation, and activates antioxidant enzymes (SOD, CAT, GPx) and detoxification pathways (MFO and esterases), indicating moderate oxidative stress.

Analysis of genetic variability in Anopheles arabiensis and Anopheles gambiae using microsatellite loci [PDF]

Insect Molecular Biology, 1999
Abstract We analysed genetic variability in Anopheles arabiensis and Anopheles gambiae populations using micro‐satellite loci to determine whether the Rift Valley restricts the flow of genes. Deviations from Hardy–Weinberg expectations

Larvicidal Activities of 2-Aryl-2,3-Dihydroquinazolin -4-ones against Malaria Vector Anopheles arabiensis, In Silico ADMET Prediction and Molecular Target Investigation

Molecules, 2020
Malaria, affecting all continents, remains one of the life-threatening diseases introduced by parasites that are transmitted to humans through the bites of infected Anopheles mosquitoes.
