Life-history traits of a fluorescent Anopheles arabiensis genetic sexing strain introgressed into South African genomic background

Malaria Journal, 2022
Background South Africa has set a mandate to eliminate local malaria transmission by 2023. In pursuit of this objective a Sterile Insect Technique programme targeting the main vector Anopheles arabiensis is currently under development.

Effects of Chilling and Anoxia on the Irradiation Dose-Response in Adult Aedes Mosquitoes

Frontiers in Bioengineering and Biotechnology, 2022
The success of the sterile insect technique (SIT) relies on the achievement of high levels of sterility and mating success of the factory-reared sterile males and thus their biological quality, which can be enhanced by the reduction of stress factors ...

Evaluating the efficacy, impact, and feasibility of community-based house screening as a complementary malaria control intervention in southern Africa: a study protocol for a household randomized trial

Trials, 2021
Background Concerted effort to control malaria has had a substantial impact on the transmission of the disease in the past two decades. In areas where reduced malaria transmission is being sustained through insecticide-based vector control interventions,

Mass irradiation of adult Aedes mosquitoes using a coolable 3D printed canister

Scientific Reports
In the last decade, the use of the sterile insect technique (SIT) to suppress mosquito vectors have rapidly expanded in many countries facing the complexities of scaling up production and procedures to sustain large-scale operational programs. While many

Efficiency assessment of a novel automatic mosquito pupae sex separation system in support of area-wide male-based release strategies

Scientific Reports
This study provides a comparative analysis of two state-of-the-art automatic mosquito pupae sex sorters currently available: the ORINNO and the WOLBAKI Biotech pupae sex separation systems, which both exploit the sexual size dimorphism of pupae. In Aedes

Chemosterilants for Control of Insects and Insect Vectors of Disease

CHIMIA, 2016
Both historically and at present, vector control is the most generally effective means of controlling malaria transmission. Insecticides are the predominant method of vector control, but the sterile insect technique (SIT) is a complementary strategy with a successful track record in both agricultural and public health sectors.

Descending control of nociception in insects?

Proceedings of the Royal Society B: Biological Sciences, 2022
Modulation of nociception allows animals to optimize chances of survival by adapting their behaviour in different contexts. In mammals, this is executed by neurons from the brain and is referred to as the descending control of nociception. Whether insects have such control, or the neural circuits allowing it, has rarely been explored.
