    Integration of Tsetse Survey Data and Agro Ecological Characteristics From Remotely Sensed and Field Observation a Geographic Information System Southern Rift Valley of Ethiopia
    (AAU, 2001-11) Bancha, Bergenie; Tilahun, Geeachew (Dr
    A tsetse fl y survey was carried out in over I00 km ~ of the study site of the Southern Rift Valley of Ethiopia Tsetse Eradication Project (SRVETEP) with the objective of imegrating the remotely sensed data. ground verified agro-ecoiogical characteristics and tsetse survey data in a geographic infonnation system (GIS). Field data collection on tsetse fly distribution and abundance and ground vegetation type observation was conduc ted in two seasons: the dry season survey (March) and the wet season survey(]une and first week of July), Seventy-eight NGU traps baited with ace tone and three week old cow urine was used for catching tsetse during each season. Traps were deployed in a transect in a selected Ix I Km. UTM (Universal Transverse Mercater) grid square . .-\ hand held receiver GPS (Garmin -1.8) was used for geo-referencing and SPS( elevation measurement ot the trappmg Sites. Remotely sensed Lands lt TM of the area taken in 1994. was anulysed .
