In: Egyptian Journal of Agricultural Research 2015.v.93(1)B,SISummary: Ecological and Toxicological studies on bat species under different conditions at some Governorates of Egypt were conduct. The survey and distribution of bat species were done at Cairo, Giza and Kafr El-Sheikh Governorates, during 2013/2014. Laboratory experiments have been conducted to evaluate the pesticidal activity of certain insecticides (Fentrothion, Chlorpyrifos, Bentazone, Lambda-cyhalothrin and Diazinon) against fruit bat, Rousettus aegyptiacus to determined LC₅₀ of this tested compounds. Rousettus aegyptiacus and Eplesicus bettal were recorded in the three studied area , while Myotis lucifugs was abundantly found in two tested areas, (Cairo and Giza only).The highest population densities of bat was recorded in October, September and November. Rousettus aegyptiacus outnumbered all surveyed bat species followed with Eplesicus bettal while Myotis lucifugs were recorded with few numbers. The obtained result revealed that the five insecticides have high control rate on the tested bat R,aegyptiacus, recording 96-h/ LC₅₀. According to LC₅₀, LC₉₀, Toxicity index at the two levels, the descending order of tested insecticides was Lambda-cyhalothrin, Chlorpyrifos, Bentazone, Fentrothion and Diazinon respectively.
