Proportional decline of Anopheles quadriannulatus and increased contribution of An. arabiensis to the An. gambiae complex following introduction of indoor residual spraying with pirimiphos-methyl: an observational, retrospective secondary analysis of pre-existing data from south-east Zambia

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 ...

The use of sequential mark-release-recapture experiments to estimate population size, survival and dispersal of male mosquitoes of the Anopheles gambiae complex in Bana, a west African humid savannah village

Parasites & Vectors, 2017
Vector control is a major component of the malaria control strategy. The increasing spread of insecticide resistance has encouraged the development of new tools such as genetic control which use releases of modified male mosquitoes.

Selection, counterselection, and conditional gene expression for genetic biocontrol of insects

Insect Science, EarlyView.
Selection, counterselection, and conditional expression can be used for sex separation. Selection (S) and counterselection (CS) genes are linked to the sex chromosomes (e.g., the X and Y chromosomes) to confer sex‐specific selection or counterselection based on the presence or absence of the S or CS genes.

Synthetic biology approaches to generate temperature‐sensitive alleles for the Sterile Insect Technique

Insect Science, EarlyView.
Abstract The Sterile Insect Technique (SIT) is an environmentally friendly, sustainable pest control approach, which uses large‐scale releases of sterile insects to suppress or eradicate target populations through infertile matings. The efficiency of SIT is enhanced by male‐only releases requiring genetic sexing strains (GSSs) that are classically ...

Composition of mosquito fauna and insecticide resistance status of Anopheles gambiae sensu lato in Itang special district, Gambella, Southwestern Ethiopia

Malaria Journal, 2022
Background Anopheles arabiensis, member species of the Anopheles gambiae complex, is the primary vector of malaria and is widely distributed in Ethiopia.

Dissecting functional components of reproductive isolation among closely related sympatric species of the Anopheles gambiae complex

Evolutionary Applications, 2017
Explaining how and why reproductive isolation evolves and determining which forms of reproductive isolation have the largest impact on the process of population divergence are major goals in the study of speciation. By studying recent adaptive radiations

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.

Developmental expression of Ap‐Vas proteins in aphids and flies reveals their evolutionary roles in insects

Insect Molecular Biology, EarlyView.
Duplication of vas genes is universally observed in aphids, and phylogenetic analysis indicates that this event predates the divergence of Aphididae and Phylloxeridae. Ap‐vas1 is germline‐specific, whereas Ap‐vas2–4 exhibit somatic expression, indicating functional divergence during aphid embryogenesis.

Multiple insecticide resistance target sites in adult field strains of An. gambiae (s.l.) from southeastern Senegal

Parasites & Vectors, 2020
Background High coverage of long-lasting insecticidal nets (LLINs) and indoor residual spraying (IRS) are the cornerstones of vector control strategy in Senegal where insecticide resistance by the target vectors species is a great of concern.
