The Iranian isolate of the species is characterized by 1103\u20131942\u00a0\u03bcm long females with their vulva at 46.9\u201357.4% of the body, tail 75\u2013118\u00a0\u03bcm long, males with spicules 60.0\u201374.5\u00a0\u03bcm long, gubernaculum 23.7\u201332.2 \u03bcm long, and infective juveniles measuring 790\u2013985\u00a0\u03bcm long. Females and males of the recovered population had shorter body when compared with the type population. Molecular identification of the recovered population was performed using the SSU and D2-D3 expansion segments of LSU rDNA, and corresponding phylogenetic trees were reconstructed and discussed. The pathogenicity of the Iranian isolate was evaluated on the larvae and adults of the poplar leaf beetle, <jats:italic>Chrysomela populi<\/jats:italic>, and the larvae of the wax moth, <jats:italic>Galleria mellonella<\/jats:italic>, under laboratory conditions. A suspension of 200 infective juveniles per ml (IJs\/ml) of the nematode was most effective against third instar larvae of <jats:italic>C. populi<\/jats:italic>, causing 75% mortality 72\u00a0hours post-exposure. In adults, mortality reached 70% at the same concentration and exposure time. For <jats:italic>G. mellonella<\/jats:italic> larvae, <jats:italic>O. insectivorus<\/jats:italic> caused 50% mortality at 200\u00a0IJs\/ml within 72 hours post-exposure. The lethal concentration 50 (LC50) values of the nematode were 77.71 and 94.06 IJs\/ml for third instar larvae and adults of <jats:italic>C. populi<\/jats:italic>, respectively, and 217.04 IJs\/ml for fifth instar larvae of <jats:italic>G. mellonella<\/jats:italic> 72 hours post-exposure at 25\u00b0C and 60% relative humidity.<\/jats:p>","DOI":"10.1017\/s0022149x25000070","type":"journal-article","created":{"date-parts":[[2025,2,28]],"date-time":"2025-02-28T07:05:14Z","timestamp":1740726314000},"source":"Crossref","is-referenced-by-count":1,"title":["First report of <i>Oscheius insectivorus<\/i> (K\u00f6rner, 1954) Andr\u00e1ssy, 1976\u00a0(Nematoda: Rhabditidae) from Iran with its efficacy against <i>Chrysomela populi<\/i> L.
