Case Studies: Successful SIT Deployments (e.g., iaea.org, icipe.org)
The deployment of the Sterile Insect Technique (SIT) against tsetse fly populations has become a cornerstone in the integrated management of African trypanosomiasis, often referred to as sleeping sickness in humans and nagana in livestock. In recent years, coordinated efforts involving international agencies and national programs have showcased the effectiveness and scalability of SIT-based interventions.
One of the most prominent and successful case studies is the eradication program on Unguja Island, Zanzibar, which was implemented by the International Atomic Energy Agency (IAEA) and the International Centre of Insect Physiology and Ecology (icipe). Following the introduction of SIT in the late 1990s, the project succeeded in eradicating the Glossina austeni tsetse population, leading to the complete elimination of trypanosomiasis on the island. This success has served as a model for subsequent SIT projects across Africa.
Building on these achievements, large-scale projects have expanded into mainland Africa. In Ethiopia’s Southern Rift Valley, for example, a collaboration between the Ethiopian government, IAEA, icipe, and other partners has integrated SIT with conventional suppression methods. By 2025, the Southern Rift Valley program has released millions of sterile male tsetse flies, resulting in a significant reduction in wild fly populations and a corresponding decline in disease incidence. The program’s success has encouraged the expansion of SIT activities into new regions, including parts of Kenya and Uganda, where similar integrated pest management frameworks are being piloted.
In West Africa, Burkina Faso has also emerged as a focal point for SIT deployment. Supported by the IAEA and regional stakeholders, the project in the Niayes area has demonstrated substantial population suppression, paving the way for phased elimination in surrounding zones. These case studies are underpinned by investments in mass-rearing and irradiation facilities, such as those managed by icipe in Nairobi and the dedicated tsetse production unit at CIRDES in Burkina Faso.
Looking forward to the next few years, these successful implementations are informing national strategies and regional collaborations. Efforts are underway to strengthen capacity for sterile male production and distribution, leveraging advances in automation and quality control. With ongoing support from organizations like the IAEA and icipe, SIT services are expected to expand further, offering sustainable vector management and supporting broader goals of poverty reduction and rural development in affected regions.
Challenges & Barriers to Scale
The scale-up of Tsetse Fly Sterile Insect Technique (SIT) services is confronted by a set of persistent challenges and barriers, many of which are anticipated to remain relevant through 2025 and the coming years. While SIT has demonstrated effectiveness in controlling and even eradicating tsetse fly populations in defined areas, expansion beyond pilot projects and isolated campaigns faces technical, financial, infrastructural, and coordination obstacles.
A central challenge is the logistical complexity inherent in SIT for tsetse flies. Mass-rearing, sex separation, irradiation, and timely aerial or ground release of sterile males require sophisticated infrastructure and expertise. Facilities such as the Joint FAO/IAEA Insect Pest Control Laboratory in Seibersdorf and the insectary at the Centre International de Recherche-Développement sur l’Élevage en zone Subhumide (CIRDES) in Burkina Faso remain among the few with the capacity for mass production and preparation of sterile males at the scale needed for large interventions (International Atomic Energy Agency). Limited regional capacity means that many affected countries depend on cross-border supply chains, increasing costs and vulnerability to disruptions.
Another significant barrier is sustained financing. SIT programs demand continuous investment over several years to achieve suppression or elimination goals. Funding volatility, often influenced by shifting donor priorities and limited national budgets, threatens program continuity. Despite support from entities such as the Food and Agriculture Organization of the United Nations and the International Atomic Energy Agency, scaling up remains heavily dependent on external funds, which may not be sustainable for long-term area-wide programs.
Technical barriers also persist. The biological requirements for effective SIT—especially the need for high-quality, competitive sterile males and the ability to target the correct tsetse fly species—demand continuous research and development. The genetic variability among tsetse fly populations, emergence of cryptic species, and adaptation to changing environments can reduce SIT efficacy and require tailored solutions (CIRAD).
Finally, effective SIT deployment hinges on integrated pest management (IPM) approaches and strong intersectoral collaboration. Insufficient coordination among veterinary, public health, and agricultural agencies—coupled with limited local technical capacity—can hinder implementation. Moreover, community engagement is essential for success, yet public awareness of SIT remains low in many endemic regions.
Looking ahead, overcoming these barriers will require increased investment in regional infrastructure, sustained financial commitments, continued technological innovation, and enhanced stakeholder collaboration. Progress in these areas will be critical to scaling the impact of tsetse fly SIT services in Africa and beyond.
Emerging Opportunities & Investment Trends
The landscape for Tsetse Fly Sterile Insect Technique (SIT) services is undergoing notable transformation as governments and international organizations intensify efforts to eradicate tsetse-transmitted trypanosomiasis in sub-Saharan Africa. The SIT approach, which involves mass-rearing and sterilizing male tsetse flies before releasing them into the environment to disrupt reproduction, is gaining renewed attention and investment due to its environmental sustainability and compatibility with integrated pest management strategies.
In 2025, significant emerging opportunities are being driven by cross-border collaborations and increased funding allocations. The International Atomic Energy Agency (IAEA) continues to support SIT expansion through its technical cooperation projects, particularly in Kenya, Ethiopia, and Senegal. The IAEA’s partnerships with national governments and research institutions have enabled the establishment and scaling up of specialized insectaries and irradiation facilities, critical for producing sterile male tsetse flies at the quantities required for field interventions.
A key investment trend is the development of public-private partnerships and the mobilization of regional funding mechanisms. The African Union Interafrican Bureau for Animal Resources (AU-IBAR) is actively promoting the Pan African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC), through which member states are pooling resources and expertise. This coordinated approach is expected to attract further investment from international donors and development banks over the next several years.
Emerging opportunities also arise in the realm of technological innovation. Automated sex-sorting, improved irradiation protocols, and advances in mass-rearing are being implemented by organizations such as the Centre International de Recherche-Développement sur l’Elevage en zone Subhumide (CIRDES) and national tsetse control programs. These advancements promise to reduce costs and increase the scalability of SIT operations.
Looking ahead, the outlook for SIT services is positive. Market opportunities are expanding as additional regions in West, East, and Central Africa are identified as candidates for SIT deployment, and as the strategy is integrated with other vector control measures. Increased recognition of the economic toll of trypanosomiasis on agriculture is likely to spur further governmental and private investment, especially where successful pilot projects can demonstrate measurable impact. Overall, the coming years are poised to see the scaling up of SIT services, the entry of specialized suppliers, and the strengthening of supply chains across Africa.
Future Outlook: Impacts on Public Health and Agriculture
The future outlook for Tsetse Fly Sterile Insect Technique (SIT) services is marked by significant potential impacts on public health and agriculture, especially as we approach and move through 2025. The use of SIT—wherein mass-reared, sterilized male tsetse flies are released to suppress or eliminate wild populations—has already demonstrated success in specific African regions and is poised for expansion and optimization in the coming years.
One of the most prominent initiatives is the ongoing program coordinated by the International Atomic Energy Agency (IAEA) in collaboration with the Food and Agriculture Organization of the United Nations (FAO). The IAEA continues to provide technical support and sterile fly production capacity to affected countries, with major SIT facilities in Burkina Faso and Ethiopia. These facilities are scaling up operations to meet regional needs, focusing on the Glossina palpalis gambiensis and Glossina fuscipes species that are primary vectors for African trypanosomiasis (sleeping sickness).
The impact on public health is expected to be significant. As SIT reduces tsetse fly densities, transmission rates of both human African trypanosomiasis (HAT) and animal African trypanosomiasis (AAT) are projected to decline further. Ethiopia’s Southern Rift Valley program, for example, is targeting the complete elimination of tsetse flies from selected areas by 2026, with localized elimination already achieved in some pilot zones (International Atomic Energy Agency). This is anticipated to reduce both disease burden in humans and livestock losses, improving food security and rural livelihoods.
In agriculture, the anticipated reduction in animal trypanosomiasis will likely translate into improved productivity. The African Union – Interafrican Bureau for Animal Resources (AU-IBAR) forecasts that effective tsetse management could generate economic benefits exceeding hundreds of millions of USD annually, through increased livestock yields and decreased veterinary costs.
Looking ahead, SIT services are expected to become more cost-effective through the integration of improved mass-rearing, genetic sexing strains, and drone-assisted aerial release technologies. The Institut Pasteur de Dakar and partners are piloting drone-based distribution of sterile males in the Niayes region of Senegal, aiming for operational efficiency and broader coverage.
By 2025 and beyond, the expansion of SIT infrastructure and services, supported by public-private partnerships and regional governments, will likely accelerate progress toward tsetse eradication in targeted zones. Success in these efforts is expected to serve as a model for other vector-borne disease control programs, with a positive ripple effect on both public health and agricultural productivity across sub-Saharan Africa.
