Abstract

A survey together with studies on population densities and relative abundance of coleopterous species were conducted by the use of light traps at AlArish city, North Sinai and Sids Agricultural Research Station, Beba City, Beni Suif during 2005. At BeniSuif the survey revealed the presence of 45 coleopterous species belonging to 31 genera of 9 families: Anobiidae, Bostrychidae, Carabidae, Cicindelidae, Dytiscidae, Elateridae, Hydrophilidae, Scarabaeidae and Staphylinidae.
While surveying NorthernSinai revealed the presence of 64 coleopterous species belong to 44 genera of 10 families: Anobiidae, Bostrychidae, Carabidae, Cerambycidae, Dytiscidae, Elateridae, Hydrophilidae, Paussidae, Scarabaeidae and Staphylinidae.
The total annual number of beetles was 4140 and 4704 beetles at Sids and AlArish, respectively. The highest numbers of coleopterous insects were catched during May to September. The peak was during July for the first region and during August for the second one. The lowest numbers were obtained through  January, February, March, November and December.
