BackgroundGlossina fuscipes fuscipes is the primary vector of trypanosomiasis in humans and livestock in Uganda. The Lake Victoria basin has been targeted for tsetse eradication using a rolling carpet initiative, from west to east, with four operational blocks (3 in Uganda and 1 in Kenya), under a Pan-African Tsetse and Trypanosomiasis Eradication Campaign (PATTEC). We screened tsetse flies from the three Ugandan PATTEC blocks for genetic diversity at 15 microsatellite loci from continental and… 

Mitochondrial DNA sequence divergence and diversity of Glossina fuscipes fuscipes in the Lake Victoria basin of Uganda: implications for control

TLDR
Tsetse re-emergence after control interventions may be due to re-invasions from outside the treated areas, which emphasizes the need for an integrated area-wide t setse eradication strategy for sustainable removal of the tsetse and trypanosomiasis problem from this area.

Genetic diversity of Glossina fuscipes fuscipes along the shores of Lake Victoria in Tanzania and Kenya: implications for management

TLDR
There is ongoing genetic admixture within sampling sites located ~35 km from each other, while sites located~65 km apart are genetically isolated from eachother, suggesting that for sites within the same genetic cluster, control efforts should be carried out in a coordinated fashion in order to avoid re-invasions.

Temporal genetic differentiation in Glossina pallidipes tsetse fly populations in Kenya

TLDR
Tsetse flies in these regions persist with levels of genetic diversity similar to that found in populations that did not experience extensive control measures, and reinforces the importance of long term monitoring of vector populations in estimates of parameters needed to model and plan effective species-specific control measures.

Genetic Differentiation of Glossina pallidipes Tsetse Flies in Southern Kenya.

TLDR
Recent anthropogenic influences such as land use changes and vector control programs have influenced population dynamics in G. pallidipes in Kenya, and that vector control efforts should include some region-specific strategies to effectively control this disease vector.

Genetic diversity and population structure of the tsetse fly Glossina fuscipes fuscipes (Diptera: Glossinidae) in Northern Uganda: Implications for vector control

TLDR
The microsatellite and mtDNA based analyses indicate that G. f.

Evidence of temporal stability in allelic and mitochondrial haplotype diversity in populations of Glossina fuscipes fuscipes (Diptera: Glossinidae) in northern Uganda

TLDR
Genetic stability and the moderate effective population sizes imply that a re-emergence of vectors from local residual populations missed by control efforts is an important risk and underscores the need for more sensitive sampling and monitoring to detect residual populations following control activities.

A spatial genetics approach to inform vector control of tsetse flies (Glossina fuscipes fuscipes) in Northern Uganda

TLDR
A novel methodological pipeline is constructed that provides a way to identify isolated populations where it will be safer and easier to implement vector control and that should be prioritized as study sites during the development and improvement of vector control methods.

Patterns of Genome-Wide Variation in Glossina fuscipes fuscipes Tsetse Flies from Uganda

TLDR
The results show that even modest sample sizes can reveal significant genetic associations in this species, which has implications for future studies given the difficulties of collecting field specimens with contrasting phenotypes for association analysis.

The population genomics of multiple tsetse fly (Glossina fuscipes fuscipes) admixture zones in Uganda

TLDR
The results indicate that older hybrid zones contain mostly parental types, while younger zones contain variable hybrid types resulting from multiple generations of interbreeding, suggesting that reproductive barriers are nearly complete in the older admixture zones, while nearly absent in the younger admixtures zones.

Genetic diversity and population structure of Glossina morsitans morsitans in the active foci of human African trypanosomiasis in Zambia and Malawi

TLDR
This study conducted a population genetic study using partial mitochondrial cytochrome oxidase gene 1 (CO1) and 10 microsatellite loci to investigate the genetic diversity and population structure of G. m.

Phylogeography and Population Structure of Glossina fuscipes fuscipes in Uganda: Implications for Control of Tsetse

TLDR
Results have revealed strong signals of current gene flow within regions that should be accounted for when planning tsetse control in Uganda, supporting the feasibility of area wide control in the Lake Victoria region by the Pan African Tsetse and Trypanosomiasis Eradication Campaign.

Genetic diversity and population structure of Glossina pallidipes in Uganda and western Kenya

TLDR
G. pallidipes populations in Kenya and Uganda do not form a contiguous tsetse belt, and Lambwe Valley appears to be a source population for flies colonizing southeastern Uganda, but this dispersal does not extend to western Uganda.

Contrasting Population Structures of Two Vectors of African Trypanosomoses in Burkina Faso: Consequences for Control

TLDR
Potential re-invasion of flies from adjacent river basins will have to be prevented by establishing buffer zones between the Mouhoun and the other river basin(s), in the framework of the PATTEC (Pan African Tsetse and Trypanosomosis Eradication Campaign) eradication project that is presently targeting the northern part of the Mouhl River Basin.

The Population Structure of Glossina palpalis gambiensis from Island and Continental Locations in Coastal Guinea

TLDR
Estimating effective population size and the degree of isolation between coastal sites on the mainland of Guinea and Loos Islands and two islands within the Loos archipelago suggest high levels of inbreeding in tsetse flies within the island samples in marked contrast to the large diffuse deme in Dubréka zones.

Polyandry Is a Common Event in Wild Populations of the Tsetse Fly Glossina fuscipes fuscipes and May Impact Population Reduction Measures

TLDR
It is suggested that population age structure may influence remating frequency, with females maintaining sperm from different mates, may enhance the reproductive potential of re-invading propagules in terms of their effective population size.

Cryptic Diversity within the Major Trypanosomiasis Vector Glossina fuscipes Revealed by Molecular Markers

TLDR
It is proposed that the morphological classification alone is not used to classify populations of G. fuscipes for control purposes, and molecular evidence generated from nuclear DNA, microsatellites and gene sequence information, mitochondrial DNA and symbiont DNA support the existence of these taxa as discrete taxonomic units.
