Genetic Diversity in Insect-Parasitic Nematodes (Rhabditida: Heterorhabditidae)

Journal of Invertebrate Pathology, 1998
Little is known about the genetic structure of various species and populations of entomopathogenic nematodes. We determined genetic variability within and among isolates of seven Heterorhabditis species using random amplified polymorphic DNA (RAPD) markers.

Natural occurrence and distribution of entomopathogenic nematodes (Steinernematidae and Heterorhabditidae) in Nepal

Journal of Invertebrate Pathology, 2010
A survey of entomopathogenic nematodes (EPN) was conducted for the first time in Nepal during June-December 2007. EPN were recovered from 29 of the 276 soil samples (10.50%). Molecular and morphological tools were used to identify the isolates. Among 29 positive samples, seven samples (24.14%) yielded heterorhabditids (Heterorhabditis indica) and 22 ...

The use of morphometric characters to discriminate populations of Heterorhabditis bacteriophora (Nematoda: Heterorhabditidae)

Zootaxa, 2023
In a survey of entomopathogenic nematodes (EPNs) in the northwest of Iran, eleven isolates of Heterorhabditis bacteriophora were recovered mainly from the soil samples of apple orchards. The isolates were identified morphologically and molecularly.

First record of entomopathogenic nematodes (Steinernematidae and Heterorhabditidae) in Costa Rica

Journal of Invertebrate Pathology, 2005
A survey of entomopathogenic nematodes was conducted in the north Pacific (Guanacaste Conservation Area) and southeast Caribbean (Gandoca-Manzanillo Natural Refuge) regions of Costa Rica. Out of a total of 41 soil samples, 5 were positive for entomopathogenic nematodes (20.5%), with 3 (12.3%) containing Steinernema and 2 (8.2%) Heterorhabditis isolates.

Diversity and distribution of entomopathogenic nematodes (Steinernematidae, Heterorhabditidae) in South Africa

Journal of Invertebrate Pathology, 2009
A total of 1506 soil samples from different habitats in seven geographic regions of South Africa were evaluated for the presence of entomopathogenic nematodes (EPN). Nematodes were isolated from 5% of the samples. Among the steinernematids, four Steinernema sp. were recovered including Steinernema khoisanae and three new undescribed species.

Heterorhabditis marelatusn. sp. (Rhabditida: Heterorhabditidae) from Oregon

Journal of Invertebrate Pathology, 1996
Abstract A new species of the nematode genusHeterorhabditiswas found during a survey of soil entomopathogenic nematodes near Seaside, Oregon.Heterorhabditis marelatusn. sp. differs from other species ofHeterorhabditisby the length of infective juvenile and gubernaculum, and the shape of spicules, bursa, and genital papillae.Heterorhabditis marelatusn.

The distribution of entomophilic nematodes (Heterorhabditidae and Steinernematidae) in North Carolina

Journal of Invertebrate Pathology, 1984
Abstract Over 500 samples of soil from cropland, vineyards, orchards, pasture, and forest habitats throughout North Carolina were tested for the presence of steinernematid and heterorhabditid nematodes by baiting with Galleria mellonella larvae. Nematodes were isolated from 13 of 14 locations and from each habitat.

Low Temperature Activity in Heterorhabditis Sp. (Nematoda: Heterorhabditidae)

Nematologica, 1991
Four isolates of Heterorhabditis sp. (H181, Hf85 and Hnhl 86 from the Netherlands and K122 from Ireland) were compared in laboratory bioassays. Galleria mellonella larvae were exposed to infective juveniles in sand for 2-5 days. There were significant differences between isolates in the number of infective juveniles that found and entered the larvae at
