Abstract

A mapping of EPN distribution in Italy, still in course, showed a high number of EPN species if compared with European and Mediterranean Countries. In the last 25 years, up to 1,500 soil samples were collected in almost all Italian regions. The EPN were isolated from agricultural fields, woodlands, sea beaches, coastal zones, uncultivated lands, river and lake borders. A total of 122 strains were collected belonging to 10 species: 38 strains of Heterorhabditis bacteriophora, 50 Steinernema feltiae, 11 S. affine, 4 S. kraussei, 8 S. apuliae, 3 S. ichnusae, 3 S. carpocapsae, 3 Steinernema strain S.sp.MY7 of S. intermedium group, and 2 different Steinernema sp. of S. arenarium group (ItS-ESC1 and ItS-C31 strains, currently under description). S. kraussei was collected only around Etna Vulcan in Sicily and 4 new species S. apuliae, S. ichnusae, Steinernema spp. ItS-ESC1 and ItS-C31 were identified. Interesting data are related also to the genetic and morphological variability of the different populations inside each species (i.e. the 50 S. feltiae strains collected can be divided in 2 genetic groups and at least 11 different morphological groups). Concerning the symbiotic bacteria the study is already started and still in progress. The high EPN biodiversity found in Italy could be related to the unique geographic shape of this country, longer than wide and to the segregation of the island fauna
