At the beginning of my doctoral research, I had no knowledge about tsetse flies, except for a distant memory from high school mentioning that their bites transmit sleeping sickness. Unraveling the intricacies of their behavior emerged as the most fascinating aspect of my research. Understanding why they behave the way they do and translating these behaviors into meaningful insights using satellite data became a thrilling endeavor.
Initially, because tsetse flies feed only on blood, I thought that their eradication might have little impact on the ecosystem, particularly considering their absence as pollinators. However, as my learning and research progressed, I realized that the existence of tsetse flies contributes to the delicate balance of biodiversity conservation in Africa. I learned that their complete removal could pose a significant threat to the biodiversity in Africa because their absence in protected zones could lead to a surge in human encroachment.
While the negative impacts of tsetse flies in areas where they coexist with humans and livestock cannot be minimized, the paradoxical dilemma — to kill or not to kill — embodies the intricate interplay between public health and biodiversity conservation, urging us to carefully weigh the consequences of our actions on both fronts.
The Impact of My Doctorate Research on Tsetse World
The outcomes of my doctoral research have sparked considerable interest within the tsetse research community. The framework developed during my study is now a cornerstone in the national mapping efforts of tsetse fly distribution, contributing to an ongoing FAO/COMBAT project. Upon reflection, I've identified three critical gaps that warrant further exploration:
Tsetse Geographic Shifts in the Face of Climate Change The understanding of how tsetse geographic ranges may shift with climate change is in its infancy. While it's known that tsetse flies struggle in disturbed environments, ongoing re-afforestation efforts, driven by global warming concerns, could potentially create new pathways for the disease vector to thrive. Moreover, the warming of previously inhospitable areas may induce a geographical shift for these flies.
Incorporating Biological Traits in Distribution Models. My doctoral research highlighted the need to integrate the biological traits of tsetse flies into distribution models. This becomes particularly crucial when aiming to reduce surveillance costs by applying existing models to map similar dynamics in different regions or timeframes.
Bridging the Gap between Disease Vector Ecology and Prevalence. In the context of planetary health, a significant gap exists in integrating disease vector ecology with disease prevalence information. This integration is vital to ensure that control methods are directed to areas of actual need. For instance, tsetse flies might be abundant in protected zones with limited human and livestock interactions. Therefore, relying solely on tsetse numbers to deploy control strategies may lead to the misallocation of resources.
