An entomopathogenic nematode in a soil sample collected from a natural forest in Mato Grosso do Sul state, Brazil was described using both morphological and molecular characteristics as a new species “Steinernema brazilense (Rhabditida: Steinernematidae)” (Nguyen et al., 2010).

Presence of an entomopathogenic nematode, Steinernema feltiae (Rhabditida: Steinernematidae) was recorded for first time in soil samples collected from grasslands and field crops in central part of Slovenia. Nematodes were isolated using Galleria-baiting technique (Bedding and Akhurst, 1975) and identified using molecular technique.

An entomopathogenic nematode in the soil samples that collected from the northern part of the Yunnan province of China was described using both morphological and molecular characteristics as new species “Steinernema xueshannense“  (Mracek et al., 2009).

Presence of entomopathogenic nematode, Heterorhabditis megidis have been reported for the first time in the soil samples collected form Eastern Black Sea region of Turkey.  Nematodes were isolated using Galleria-baiting technique (Bedding and Akhurst, 1975) and identified using classical morphological (Poinar et al. 1987) and molecular techniques (Yilmaz et al., 2009).
