“…The F ST estimate of 0.25 was supported by further allozyme work on Kenyan and Ethiopian G. pallidipes samples (E.S. Krafsur, unpublished data) and by diversities at microsatellite loci (54). A study of mitochondrial variation in G. pallidipes disclosed an even greater degree of genetic differentiation among 18 populations from Ethiopia, Kenya, Zambia, Zimbabwe, and Mozambique.…”

“…Most early work on tsetse genetics was reviewed by Gooding (25), but subsequent reviews were limited to the following specific topics: hybrid sterility (31), quality control in tsetse colonies (30), tsetse fly-trypanosome interactions (92), use of paratransgenics to suppress vector competence (1,5), and genetics of natural populations in relation to dispersal (51,54). Much of the recent literature has not been covered in these reviews, and no recent comprehensive review of tsetse genetics has been published.…”

Tsetse flies (Diptera: Glossinidae) constitute a small, ancient taxon of exclusively hematophagous insects that reproduce slowly and viviparously. Because tsetse flies are the only vectors of pathogenic African trypanosomes, they are a potent and constant threat to humans and livestock over much of sub-Saharan Africa. Despite their low fecundity, tsetse flies demonstrate great resilience, which makes population suppression expensive, transient, and beyond the capacities of private and public sectors to accomplish, except over small areas. Nevertheless, control measures that include genetic methods are under consideration at national and supranational levels. There is a pressing need for sufficient laboratory cultures of tsetse flies and financial support to carry out genetic research. Here we review tsetse genetics from organismal and population points of view and identify some research needs.

“…This was surprising given the mobility of the flies combined with expectations derived from population genetics theory [20][21][22]. The analysis of mitochondrial DNA revealed relatively high levels of haplotype divergence between randomly chosen individuals among four species analysed, including G. morsitans [20]. However, arthropod mitochondrial genomes are small in size (14 -25 kilobases) and maternally inherited [23], hence, data interpretation differs from that of variation in nuclear genes.…”

Trypanosomosis remains the number one killer of livestock in spite of efforts made to eradicate tsetse flies in the Adamawa plateau of Cameroon. Acetone-baited Laveissière type biconical traps were pitched at 100 meter intervals in strategic geo-referenced positions in various ecological niches of the landscape for 5 consecutive days in selected villages in Mayo Rey, Mbere, Vina and Faro et Deo divisions. All 493 tsetse flies captured in sites other than Mboula were G. morsitans submositans. Measurement of different morphometric characters on the wings of each individual fly was undertaken using the Du Jardin package. The data was processed and analysed by "Permutaciones, Analisis Discriminante (PAD)" and "Bootstraps, Analisis en Componentes principales". The three major sampling sites on the plateau yielded similar results as demonstrated by the neighbour joining tree of Mahalanobis distances but tests using PAD showed the differences between group means to be significant (P < 0.05) even when the same number of flies was used. Mixing of tsetse populations from the northern lowlands and those on the plateau and Koutine plain could not be ruled out. These preliminary findings suggest that the flies are not from isolated populations and should be considered as populations frequently exchanging migrants. However, molecular genetics techniques are necessary in addition to morphometric analysis to reach more definitive conclusions.

“…Recent progress in tsetse fly population genetics includes the Solano et al (1997) examination of microsatellite variation in Glossina palpalis gambiensis and G. p. palpalis natural populations. Baker and Krafsur (2001) and Ouma et al (2003) uncovered microsatellite loci in the morsitans group of tsetse flies, and the population genetics of diverse natural morsitans group populations have now been investigated (reviews in Krafsur, 2003;Gooding and Krafsur, 2005). Additional genomic DNA markers would be most useful, and here we report three new microsatellite loci and their homologs in other tsetse fly taxa.…”

We report the development and characterization of three new microsatellite markers in the tsetse fly, Glossina pallidipes (Diptera: Glossinidae). Fifty-eight alleles were scored in 192 individuals representing six natural populations. Allelic diversity ranged from 9 to 28 alleles per locus (mean 19.3 ± 5.5). Averaged across loci, observed heterozygosity was 0.581 ± 0.209, and expected heterozygosity was 0.619 ± 0.181. Cross-species amplifications of the G. pallidipes loci in other tsetse fly taxa are reported.
