Résumé
The captured rodents throughout four successive years from 2003 to 2006 in the surveyed localities (El-Edwa, Samallout, Minia and Mallawy) were classified into species and subspecies. according to Schwartz (1960). The occurrence percentages were recorded by dividing the number of the captured species or subspecies from the total numbers the captured rodents. The rodents recorded in the all tested localities and years were Rattus norvegicus, Rattus r. frugivorous, Rattus r. alexandrinus and Mus musculus. The highest occurrence percentage (54.5%) was recorded with Rattus r. frugivoroius in El-Edwa during 2006. This subspecies recorded the highest average percentage (47.28%) during the surveyed years. In contrast, the lowest average percentages (0.0, 0.35, 0.80 and 1.77%) were observed with Arvicanthus niloticus in Sammallout, El-Edwa, Mallawy and Minia, respectively. Acomys c. cahirinus and Arvicanthus niloticus disappeared from 2003 to 2005 in El-Edwa. On the other hand Arvicanthus niloticus disappeared in Mallawy samples from 2005 to 2006. The field may be due to considered the field rodents and not entres the buldings to get the food only and go out to the field. The highest occurrence of Rattus norvegicus (15.1 %) was registered in Minia locality because the species preferred the organic methods and stay in buldings .
