“…Tsetse flies were collected from various highly tsetse infested areas in Nigeria (Table 1 ), among these three National Parks. The sampling sites were located several hundred kilometres from each other ranging from the forest, derived savannah to southern guinea savannah geo-ecological zones [ 31 ]. The survey was conducted during the end of the dry season March 2014.…”

BackgroundTsetse flies are vectors of trypanosomes, parasites that cause devastating disease in humans and livestock. In the course of vector control programmes it is necessary to know about the Glossina species present in the study area, the population dynamics and the genetic exchange between tsetse fly populations.ResultsTo achieve an overview of the tsetse fly diversity in Nigeria and at the Nigeria-Cameroon border, tsetse flies were trapped and collected between February and March 2014 and December 2016. Species diversity was determined morphologically and by analysis of Cytochrome C Oxidase SU1 (COI) gene sequences. Internal transcribed spacer-1 (ITS-1) sequences were compared to analyse variations within populations. The most dominant species were G. m. submorsitans, G. tachinoides and G. p. palpalis. In Yankari Game Reserve and Kainji Lake National Park, G. submorsitans and G. tachinoides were most frequent, whereas in Old Oyo National Park and Ijah Gwari G. p. palpalis was the dominant species. Interestingly, four unidentified species were recorded during the survey, for which no information on COI or ITS-1 sequences exists. G. p. palpalis populations showed a segregation in two clusters along the Cameroon-Nigerian border.ConclusionsThe improved understanding of the tsetse populations in Nigeria will support decisions on the scale in which vector control is likely to be more effective. In order to understand in more detail how isolated these populations are, it is recommended that further studies on gene flow be carried out using other markers, including microsatellites.

“…These rivers (Niger and Benue), with their extensive flood plains, drain the area across sedimentary rocks that characterize the lowing-lying plains (Ologe, 2002). The vegetation is classified as Guinea Savanna and the rainfall pattern is characterized by a wet season which lasts from April to October (Odekunle, 2004;Fashae et al, 2017) with an annual rainfall ranging between 800 and 1100 mm (Sani and Haruna, 2010). The agro-climatic conditions within the state enable the cultivation of food and tree crops.…”

The study confirmed that a total of 69 buildings out of 611 buildings were affected by the flood disaster with about 24,902 people displaced by this singular flood event. The study shows that backscattering from microwave sensors provides very useful information for highlighting inundated areas that could prove useful in forecasting, monitoring, and precision-based flood early warning designs before, during, and after flood events.

“…This may be attributed to changing precipitation pattern in the country and land use/land cover changes as a result of increase in population. Fashae et al, (2017) noted the relationship between precipitation and NDVI in the country. Figure 2 presents the correlation between carbon and NDVI.…”
