معرفي چند گونه Criconematid از پوشش گياهي تبريز و حومه

SOME SPECIES OF CRICONEMAT1DS FROM TABRIZ AND ITS SUBURBS*

In order to identify plant-parasitic nematodes belonging to criconematids in Tabriz and its suburbs, 85 soil and root samples were collected from rhizosphere of vegetations during 2006-2007. The nematodes were recovered using the sieving and centrifugal-flotation technique and processed to anhydrous glycerin. The extracted nematodes were mounted in permanent microscopic slides. As a result, one species of Criconema, under the name of C. mutabile, seven species of Criconemoides, viz. C. antipolitanus , C. curvatus , C. informis , C. ornatus , C. parvus , C. pseudosolivagus and C. xenoplax\ two species of Ogma, viz. O. civellae and O. fimbriatum\ three species of Hemicycliophora,viz. H. poranga, H. sturhani and H. vaccinium were identified. H. vaccinium and O.fimbriatum are new records from Iran.
