Abstract
ABSTRACT: In this study, a survey of Egyptian fruit bat, Rousettus aegyptiacus and insect bat, Pipistrellus deserti was conducted at Gharbia, Beheira, Ismailia and Qaliobia Governorates along two successive years (2013 and 2014) to throw the light on the seasonal variation of these animals. The total collected number of Egyptian fruit bat , R. aegyptiacus were 123.1, 144.0, 101.5 and 111.4 bats, respectively in the previously mentioned governorates , with average seasonal numbers of 30.78, 36.03, 25.38 and 27.85 bats / m 2 , respectively. Beheira Governorate occupied the highest numbers of the Egyptian fruit bat , followed by Gharbia, and Qaliobia , while Ismailia Governorate recorded the least numbers. The obtained results showed that Autumn season was the most favorable one for R. aegyptiacus activity, followed by Summer, and Spring, while Winter season was the least favorable season for bat activities. In addition, the obtained results revealed that the total collected number of insect bat , P. deserti was 138.0, 122.8, 132.7 and 147.8 bats in Gharbia, Beheira, Ismailia and Qaliobia Governorate, respectively, with average seasonal numbers of 34.5, 30.7, 33.18 and 36.95 bats / m 2 , respectively. Qaliobia governorate recorded the highest numbers of insect bat, but Beheira regions was the lowest one. Furthermore, the current study showed that Summer season was the most favorite one for P. deserti bat activity, while Winter season recorded the lowest favorite one.
