ASSESSMENT OF DAMAGE CAUSED BY RODENT INFESTATION IN DIFFERENT FIELD CROPS AT KAFR EL- SHEIKH AND GHARBIA GOVERNORATES.

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.
