ESTIMATION OF INJURY CAUSED BY HOUSE SPARROW, Passer domesticus niloticus (L.) IN WHEAT CROP AT ASSIUT GOVERNORATE

The present work was carried out to estimate the damage caused by the house sparrow (Passer domesticus niloticus L.) in the pre harvest stage of wheat crop at the Experimental Farm of Agricultural Research Center of Faculty of Agriculture AL – Azhar University at Assiut governorate, Egypt. This work was an attempt to study, the relationship between the losses caused by house sparrow and the planting nearby of buildings, animal husbandry and trees of orchards. The obtained results revealed that the highest damage of wheat occurred at the nearby cultivations of buildings and animal husbandry (25.87 19.20%). On the other hand, the lowest damage was observed in the nearby cultivations of orchards (9.33%). The statistical analysis of data revealed that a highly significant differences between the percentages of damage for the distances toward the middle of the cultivated field, (42.80, 7.40 3.30%) respectively. Also, there is a highly significant difference between the percentages of damage for both the date of planting i.e. the early and late date and moderate date. But, it is insignificant difference between the percentages of damage for both the early and late date (14.93 14.40%) respectively.
