Survey of rodents was conducted, at Al-Azhar University Experimental Farm in Assiut. This studies were achieved throughout two year in field crops  and woodlands areas . In both areas 50 wire-box traps of the usual spring door (25×12×10 cm) were baited and distributed twice every 15 days. the Survey of rodents in field crops  and woodlands areas revealed the presence of four species of rats and mice . These species were ranked in the field crops as percentage of the total rodents in each year in the following orders, Arvicanthis niloticus (Desm.) (63.09 and 72.08%), Rattus. Rattus frugivorus (5.58 and 3.6%), Rattus. r. alexandrinus (1.28 and 5.4%) while Mus  musculus Linn. ( 30.05 and 18.92%) for the first and second year respectively. While in woodlands area were (37.33 & 32.8 %),.(9.22 & 13.6%) , (23.05 & 26.4%) and (29.95 & 27.2% ) for the same species and two years respectively.  Also, it was found five individuals of  the spiny mouse, Acomys cahirinus cahirinus  were captured during the same period.  Generally, the number of  rodents trapped from the field crops and woodlands areas during 2004/2005 (236 individuals)  was decreased as compared with the number  trapped from the same areas through 2003/2004,( 450 individuals) .The decreased of the density may be due to the shortage  of  food in this area through the last year . In the woodlands area the highest seasonal index was recorded in spring while the lowest one in winter.
