The damage caused by rodent infestation for some field crops in different
location i.e nearly buildings, nearby poultry farmes and nearby storehouse in addition
to control in Kafr EI-Sheikh and Gharbia Governorates during the two successive
seasons 2002 and 2003 were studied. Results of rice crop revealed that the damage
percentages in immature and mature stages were [ (2.5 and 2.8 %) and (1.2 and 1.4
%)] and [ (2.6 and 2.8 %) and (1.8 and 2.2 %)], [ ( 2.6 and 3.6 % ) and (1.5 and 2 %)]
and [ ( 2.6 and 2.9 %) and (2 and 2.2 % ) ], [ (2 and 1.2 %) and ( 0.8 and 0.8 %)] and [
( 1.9 and 2.5 %) and ( 1.4 and 1.8 %)], [ ( 1.8 and 2 % ) and ( 0.7 and 0.9 % )] and [ (
1.4 and 1.9 %) and ( 1.1 and 1.1 %)] and [ ( 1 and 0.8 % ) and (0.5 and 0.5 %)] and [(
1.4 and 1.8 %) and (1 and 1.3 %)], with total mean average damage percentages of [ (
2 and 2.3 %) and (0.9 and 1.1 % )] and [ ( 2 and 2.4 % and (1.5 and 1.7 % )],
respectively, for immature and mature stages of rice crop. For broad bean crop damage percentages were [ (1, 1.3, 0.8,0.9 and 0.7 %) and
( 1.1, 1.5, 1, 1.2 and 0.8 %)] and [ ( 0.9, 1.3, 0.9, 0.9 and 0.6 %) and (1.1, 1.2, 1.1, 0.7
and 0.7 %)] with mean damage percentages of [ ( 1 and 1.1 % ) and ( 0.9 and 1 % )],
respectively. For wheat crop damage percentages were [( 0.6, 1, 0.8, 0.6 and 0.4 % ) and (
0.9, 1.2, 1, 0.6 and 0.5 % )] and [ ( 0.9, 1.3,0.6,0.8 and 0.4 %) and ( 1.3, 1.6,0.9,0.7
and 0.5 % )] with mean average damage % of [ ( 0.3 and 0.4 % ) and ( 0.6 and 0.5 % )
], respectively for the different location during the two tested seasons in the two
Governorates. For maize mature stage % of damage in the different tested location at two
sowing date during the two tested seasons in the two experimental Governorates
were [( 2.1,2, 1.6, 1.3 and 0.7 %), ( 2.3, 2.5, 1.7, 1.4 and 0.8 %)] and [ ( 5, 4.6, 4.6.
4.8 and 3.6 %), ( 5.4, 5.9, 5.8, 5.5 and 4.3 % )]. respectively, in Kafr EI-Sheikh and [
(1.3, 1.4, 1.1, 1.2 and 0.4 %), ( 2.1, 1.9, 1.8, 1.7 and 0.6 % )] and [ ( 3.4, 3.8, 3.4, 3.6
and 1.8 %), (4.5,4.7,4.3,3.7 and 2.2 %)], respectively in Gharbia Governorate.
