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

open access: yesInsect Science, Volume 33, Issue 2, Page 517-532, April 2026.
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 ...

Differences in malaria vector biting behavior and changing vulnerability to malaria transmission in contrasting ecosystems of western Kenya

open access: yesParasites & Vectors, 2023
Background Designing, implementing, and upscaling of effective malaria vector control strategies necessitates an understanding of when and where transmission occurs.

A CRISPR-Cas9 sex-ratio distortion system for genetic control. [PDF]

open access: yes, 2016
Genetic control aims to reduce the ability of insect pest populations to cause harm via the release of modified insects. One strategy is to bias the reproductive sex ratio towards males so that a population decreases in size or is eliminated altogether ...

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

open access: yesInsect Science, Volume 33, Issue 2, Page 618-639, April 2026.
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.

Filling the gap 115 years after Ronald Ross: the distribution of the Anopheles coluzzii and Anopheles gambiae s.s from Freetown and Monrovia, West Africa.

open access: yesPLoS ONE, 2013
It was in Freetown, Sierra Leone, that the malaria mosquito Anopheles coastalis, now known as Anopheles gambiae, was first discovered as the vector of malaria, in 1899.

Chemical Cues for Malaria Vectors Oviposition Site Selection:\ud Challenges and Opportunities [PDF]

open access: yes, 2013
The attractiveness of oviposition site for malaria vector mosquitoes is dependent upon a number of physical and chemical factors. Many aspects of mosquito behavior, including host location and oviposition, are mediated by volatile semiochemicals.

Climate Change and Highland Malaria: Fresh Air for a Hot Debate [PDF]

open access: yes, 2010
In recent decades, malaria has become established in zones at the margin of its previous distribution, especially in the highlands of East Africa.

Hybrid incompatibilities in the anopheles gambiae species complex

open access: yes, 2021
Malaria is an infectious disease caused by parasites of the genus Plasmodium which is responsible for approximately 400,000 deaths annually, primarily in sub-Saharan Africa. Malaria is transmitted by mosquitoes belonging to the Anopheles gambiae species complex.

Genomic Signatures of Microgeographic Adaptation in Anopheles coluzzii Across Urban, Rural, and Forested Environments in Gabon

open access: yesMolecular Ecology, Volume 35, Issue 8, April 2026.
ABSTRACT Species distributed across heterogeneous environments often evolve locally adapted populations, but understanding how these persist in the presence of homogenizing gene flow remains puzzling. In Gabon, Anopheles coluzzii, a major African malaria mosquito, is found in various ecological settings, including urban areas, remote rural villages ...

Genetic Basis of Cuticular Hydrocarbon Variation in the Desert Ant Cataglyphis niger

open access: yesEcology and Evolution, Volume 16, Issue 3, March 2026.
Cuticular hydrocarbons (CHCs) are a ubiquitous component of ant cuticles that are used for a wide range of chemical signaling functions, especially recognition. Here we tested for a genetic basis of CHC variation in the desert ant Cataglyphis niger. We applied a genomic mapping approach to discover associations between CHCs and 20 quantitative trait ...
