Abstract :

During 2008-2009, in a faunal study of Miridae family in the agricultural farmlands and gardens of Arak and the suburbs, 25 species belonging to 17 genera of 5 subfamilies were identified; A  species marked with asterisk, is newly recorded from Iran. Most of collected species, are                  phytophagous, where, some of them have been already introduced as agricultural pests. For                example Lygus rugulipennis Poppius 1911, as an important agricultural pest in Arak, the most abundant species among the harmful collected species (35/09%), but few studies have been                conducted regarding its economic importance. The rest of the species (6 species) are predator  which among them Deraeocoris punctulatus (Fallen, 1807) was determined as the dominant               predator. The list of the collected species is as follow. Lygus rugulipennis Poppius, 1911 Lygus gemellatus (Herrich-Schaeffer, 1835) Lygus pratensis (Linnaeus, 1758) Polymerus vulneratus (Panzer, 1805) Polymerus cognatus (Fieber, 1858) Eurystylus bellevoyei (Reuter, 1879) Orthops sangvinolentus (Reuter, 1879) Adelphocoris lineolatus (Goeze, 1778) Stenodema calcarata (Fallen, 1807) Stenodema turanica Reuter, 1904 Trigonotylus pulchellus Hahn, 1834 Deraeocoris serenus (Douglas and Scott, 1868) Deraeocoris punctulatus (Fallen, 1807) Deraeocoris lutescens (Schilling, 1837) Deraeocoris pilipes (Reuter, 1879) Plagiognathus fulvipennis (Kirschbaum, 1856) Europiella artemisiae (Becker, 1864) Europiella sp.
