A survey conducted during 2006 and 2008 showed the presence of both heterorhabditid and steinernematid nematodes in the Arasbaran forests and rangelands, Iran. Based on both morphological and molecular characteristics, heterorhabditid isolates were identified as Heterorhabditis bacteriophora whereas the steinernematid isolates were identified as Steinerenma carpocapsae, S. bicornutum, S. feltiae, S. glaseri, S. kraussei.
