Presented study is part of a project aimed at identifying entomopathogenic nematode (EPN) species and analysing their distribution in various habitats of Poland. Here, an attempt was undertaken to determine intraspecific variability of nematodes of the species
Research on the occurrence of EPNs in Poland have been conducted since the 1990s but there is still no data verified genetically, as well as data on the intraspecific variability of isolates
