The Eastern Horn of Africa (Somalia, Ethiopia, Djibouti and Kenya) exhibits strong rainfall anomalies, considering the latitudinal position of the region. The mean annual rainfall map shows a vigorous meridian contrast between the rainy Western Highlands of Kenya and Ethiopia, and the deficiency of the lowlands of Somalia, the Eastern parts of Kenya and Ethiopia, and the Red Sea coast. This opposition is mainly related to the northern summer season, during which the different caracteristics of the wet "west-african" monsoon and the dry divergent "indian" monsoon are clearly emphasized. They induce single-maximum summer rainfall regimes, and double-peak spring and autumn regimes, respectivel…

The contact between human and wild fauna has considerably increased during these last decades due to the increase of human population size but also to conservation policies. As a consequence, the number of zoonotic diseases soared with a mean of six new infectious diseases per year, 75% of whom being vectorially transmitted. The way to avoid the human contamination by these emergent diseases is based on the efficient vector control resulting from a deep knowledge of the ecology and the feeding behavior of the different vector species. During our work, we have identified and characterized the ecology of 6 tsetse species (Glossina palpalis palpalis, G. fuscipes fuscipes, G. fusca congolense, …
