A new malaria mosquito arises in Africa.
Fighting Malaria with Gene Tech
As the head of medical entomology and parasitology at Burkina Faso's Research Institute in Health Sciences, Dr. Diabate's cutting-edge research has earned him the esteemed 2023 Falling Walls Prize for Science and Innovation Management.
Interesting Engineering reported that organizers lauded his work as a beacon of hope for malaria control, recognizing its potential to bring about transformative changes in the fight against the disease.
Malaria continues to pose a significant threat in Burkina Faso, affecting nearly all of the country's 22 million residents, particularly placing children at risk of contracting this mosquito-borne illness.
With the World Health Organization (WHO) reporting almost 19,000 lives lost to malaria in Burkina Faso in 2021 alone, Dr. Diabate's pioneering approach represents a crucial step forward in the ongoing battle against this deadly disease.
While conventional methods like insecticide-treated bed nets have played a crucial role in diminishing malaria transmission and fatalities, Dr. Diabate stresses the need for solutions due to the growing challenge of insecticide resistance and the escalating costs associated with interventions.

Recognizing the limitations of traditional tools, Diabate has introduced a groundbreaking approach-a gene drive technology designed to target female Anopheles mosquitoes, the primary carriers of malaria.
This cutting-edge method involves the controlled release of sterile genetically modified male mosquitoes, disrupting the reproductive cycle by preventing the production of female offspring when mating with wild females.
Over time, this intervention led to a significant reduction in the female mosquito population, representing a substantial breakthrough in the ongoing efforts to curb malaria transmission.
Releasing Gene-Edited Mosquitos
Dr. Diabate envisions that once the gene-edited mosquitoes are released into the environment, they will naturally disperse throughout the entire mosquito population, leading to an immediate reduction in malaria transmission.
Emphasizing the cost-effectiveness and sustainability of this method in comparison to traditional interventions, CNN reported that he underscores its potential as a game-changing approach.
However, the realization of this technology necessitates further research and development. The initial phase of the project, conducted in 2019 by Diabate's research alliance, Target Malaria, involved releasing a group of sterile male mosquitoes in a controlled setting.
While this release wasn't intended to impact transmission, it yielded valuable data crucial for advancing the technology.
Diabate's gene-editing research is not the sole effort exploring mosquito control through genetic modification. In 2013, the US biotech company Oxitec developed a similar technology targeting the Aedes aegypti mosquito, known for transmitting yellow fever, dengue, and Zika.
One distinctive aspect of Diabate's approach lies in the focus on modifying male mosquitoes, potentially mitigating ecological concerns compared to methods targeting females-vital food sources for various animals.
Despite this advantage, concerns about the long-term environmental impact of gene drive technology persist, prompting advocacy groups such as Save Our Seeds to advocate for caution and comprehensive research.
