Abstract

The evaluation of the damage caused by common rats in some field crops (wheat, kidney bean and peanut) during cultivation season 2005- 2006, stored Peanut, Maize and onion during 2005 -2006 and chicken factory of hatching eggs during May 2006 to April 2007.The damage caused by R. rattus frugivorous and R. rattus rattus in wheat fields during the milky, pasty (dough) and mature stages. The rate of damage increased toward the mature stage as the damage caused to peanut percentage was 8.28%, 12.18% and 14.98% to milky, pasty and mature stages respectively. The percentage of damage was 0.14%, 0.78% and 1.17% to full size pod, full size seed and mature stages respectively. Kidney bean damage ranged between 0.15% and 0.58% (with an average of 0.35%). Peanut and Maize damage percentage in stores ranged between (0.9% and 7.07%) and (1.83% and 6.41%). Onion damage in stores was estimated, and found to be negligible as it was ranged between 0.13% and 0.2%. These stored crops could be arranged according to damage % as follow: Maize (4.22%), peanut (2.57%) and onion (0.18%). The total of the damaged eggs was 7350 eggs/year which constituted 0.182% of total eggs and the chicks killed by R. norvegicus (Berk.) were 2940 chicks/year, which constituted 0.096% of total chicks produced.
