Identification and intraspecific variability of Steinernema feltiae (Filipjev, 1934) isolates from different localities in Poland

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 Steinernema feltiae isolated from seven different localities in central and southern Poland. Molecular characteristic and phylogenetic analysis was performed based on nucleotide sequences in the ITS region.

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 Steinernema feltiae. This paper reports initial results of intraspecific variability Steinernema feltiae in Poland.
