Damage In Wheat Fields Caused by The House Sparrow (Passer domesticus niloticus Nicoll and Bonhote, 1909) At Sharkia Governorate, Egypt

Abstract

The damage in wheat fields caused by the house sparrow, Passer domesticus niloticus Nicoll and Bonhote, 1909 was estimated around different distances of certain sites at Sharkia governorate. Results revealed that wheat fields nearby houses significantly showed the highest values of damage (24.41%); whereas, wheat fields around animal husbandries significantly recorded median values of damage (16.53%). The lowest value of loss in wheat (7.87%) was significantly investigated in fields lay around fruit orchards. On the other hand, the damage caused by the house sparrow decreased with increasing the distances around the tested sites. The rate of damage in wheat fields due to house sparrow attack showed the highest value (50.01%) nearby houses; while, it gradually decreased to 33.87% around animal husbandry and 16.12% around fruit orchards. But, the rate of damage recorded the highest values of 80.33% at 10 meters; sharply decreased to 14.20% at 25 meters and 5.47% at 40 meters.
