HAPLOTYPE DIVERSITY OF STEINERNEMA FELTIAE (NEMATODA: STEINERNEMATIDAE) IN EURASIA

open access: yesRedia, 2020
Phylogenetic analysis of ITS rDNA sequences of the entomopathogenic nematode Steinernema feltiae Filipjev, 1934 (Wouts, Mráček, Gerdin and Bedding, 1982) was used to infer intraspecific genetic variability of this rhabditid nematode. Nucleotide intraspecific differences among S. feltiae isolates reached the level of 19 base pairs per ITS rDNA region, i.

Entomopathogenic nematode (Heterorhabditidae and Steinernematidae) spatial distribution in turfgrass

open access: yesParasitology, 1996
SUMMARYUnderstanding the temporal and spatial distribution of entomopathogenic nematodes is essential for determining the role of these insect parasites in soil communities and ultimately for their use in suppression of pest insect populations. We measured the vertical and horizontal distribution of endemic populations of entomopathogenic nematodes ...

Steinernema akhursti sp. n. (Nematoda: Steinernematidae) from Yunnan, China

open access: yesJournal of Invertebrate Pathology, 2005
A new species of entomopathogenic nematode, herein described as Steinernema akhursti sp. n., was recovered from soil samples collected from Yunnan Province, the People's Republic of China. Both morphological and molecular data show congruently that S. akhursti sp. n. belongs to the Steinernema feltiae group.
