外文摘要：The entomopathogenic nematode, Steinernema borjomiense, was isolated from north Iran, and identified herein based upon morphological and molecular data. The Iranian isolate of this species is characterised by its 645-910 mu m long infective juveniles, having brown-golden spicules 52-67 mu m long in first, and 30-51 mu m long in second generation males. The pathogenicity of the recovered population of S. borjomiense was evaluated on the larvae of two exotic invasive forest pests in north Iran, the box tree moth (BTM), Cydalima perspectalis, and the fall webworm (FWW), Hyphantria cunea, under laboratory conditions. The results indicated that the lethal concentration 50 (LC50) values of nematode were 60.2 and 180.3 IJ larva(-1) on fifth and fourth instar larvae of BTM; and 96.7 and 213.8 IJ larva(-1) on fifth and fourth instar larvae of FWW, respectively, after 48 h at 25 degrees C and 60% relative humidity (RH). Together, the present results corroborated the efficacy of this isolate for biocontrolling BTM and FWW in laboratory conditions.
