Africa: Exploring the Future of Vector Control

On 18 August 2026, the APMEN Vector Control Working Group hosted a World Mosquito Day webinar, drawing over 700 specialists from 69 nations to discuss the future of mosquito vector control. The event aimed to explore how cutting-edge tools and collaborations could bolster malaria and other mosquito-borne disease control efforts.
While insecticide-treated nets and indoor residual spraying have historically been pivotal in malaria prevention, their limitations have become increasingly apparent. Insecticide resistance, outdoor transmission, and shifting mosquito behavior have posed significant challenges. Professor Leo Braack of Malaria Consortium Asia emphasized that these issues necessitate innovative solutions and stronger entomological capacity.
Several promising approaches are emerging. Spatial emanators, which release chemicals to reduce mosquito populations, show promise for both indoor and outdoor use, though further research is needed on their standalone effectiveness and cost. Endectocides, such as ivermectin, can render mosquitoes toxic to malaria vectors, as demonstrated by the BOHEMIA trial in Kenya, which reported a 26 percent reduction in malaria incidence alongside high net coverage.
However, the long-term impact of treating livestock with these drugs requires further investigation. Gene drive technology, while promising, remains controversial and poses significant challenges, including resistance, ecological impact, and the lack of field testing. Meanwhile, Wolbachia, a naturally occurring bacterium, has demonstrated success in reducing the transmission of diseases like dengue by Aedes aegypti mosquitoes.
Despite these advancements, existing tools like insecticide-treated nets and indoor residual spraying remain crucial. The future of vector control will hinge on intelligent combinations of these tools, guided by local evidence, surveillance, cost-effectiveness, implementation capacity, and community engagement. Dr. Muhammad Mukhtar of Pakistan's Directorate of Malaria Control proposed a three-actor partnership model involving national programs, academia, and industry to drive this innovation.
APMEN remains committed to facilitating dialogue among stakeholders to translate emerging research into effective global solutions.
