| Abstract | ||||
| A survey together with studies on population densities and relative abundance of hemipterous insccts were conducted by the use of a Robinson light trap at Al-Arish city, North Sinai during two successive years (October, 1994-September, 1996). The survey revealed the presence of 92 hemipterous species belonging to 58 genera of 16 families: Alydidae, Anthocoridae, Berytidae, Coreidae; Cydnidae, Dicranocephalidae, Joppeicidae, Lygaeidae, Miridae, Nabidae, Pentatomidae, Plasidae, Piesmidae, Pyrrhocoridae, Reduviidae and Rhopalidae. The total annual number of bugs was 13908 and 7272 bugs in the first and second years, respectively. The highest numbers of bugs were trapped during May-October. The peak was during September in the first year and in August in the second one. The lowest numbers were obtained through December-March. Families Pentatomidae and Lygaeidae contained the largest number of species and/or individuals, followed by families Reduviidae, Cydnidae and Miridae, respectively. Other families were represented by lesser number of individuals and/or species. Individuals of the species Nysius emcee, Nysius cymoids (Lygaeidae), Eusarcoris ventralis and Nysius viridula (Pentatomidae) were found to be the most abundant and active species in the two years of study. | ||||
