Screening of two native isolates of entomopathogenic nematodes, Heterorhabditis indica and Heterorhabditis bacteriophora, for temperature and moisture stress tolerance

Journal of Oilseeds Research, 2022
Entomopathogenic nematodes (EPNs) are obligate parasites infecting a wide range ofinsect species and are one of promising biocontrol agents with potential in insect pest management. Temperature and soil moisture play an important role for their sustenance in soil and their efficiency varies greatly under different climatic conditions.

Activity and infectivity of four isolates of Heterorhabditis spp

Journal of Invertebrate Pathology, 1989
Abstract Four unidentified isolates (three Dutch and one Italian) of Heterorhabditis spp. were compared using Galleria mellonella larvae as host. The isolates differed in the ability of infective juveniles to find and/or enter larvae in moist sand at 12°C. When three monoxenic infective juveniles were injected into the hemocoel of G. mellonella

Morphological Mutant in the Entomopathogenic Nematode, Heterorhabditis bacteriophora

Journal of Heredity, 1993
Heterorhabditis bacteriophora is an entomopathogenic nematode that has potential as a biological control agent. As a first step in the genetic analysis of this nematode, we induced and isolated a short nematode (dumpy) from the F2 progeny of an EMS mutagenized nematode. Phenotypically, the dumpy adult is 60% shorter than the wild type.

Photorhabdus luminescens subsp. noenieputensis subsp. nov., a symbiotic bacterium associated with a novel Heterorhabditis species related to Heterorhabditis indica

International Journal of Systematic and Evolutionary Microbiology, 2013
The bacterial symbiont AM7T, isolated from a novel entomopathogenic nematode species of the genus Heterorhabditis, displays the main phenotypic traits of the genus Photorhabdus and is highly pathogenic to Galleria mellonella.

Host influences on the pathogenicity of Heterorhabditis megidis

BioControl, 2001
The infectivity of infective juveniles(IJs) of Heterorhabditis megidis (strain NLH-E87.3) produced on small, medium and large larvae ofGalleria mellonella, and on medium and largelarvae of Otiorhynchus sulcatus was tested underlaboratory conditions against G. mellonella andO. sulcatus larvae. Infective juvenilesoriginating from small G.

Heterorhabditis bacteriophora Nematodes are Sensitive to the Bacterial Pathogen Photorhabdus asymbiotica

Journal of Parasitology, 2023
The entomopathogenic nematode (EPN) Heterorhabditis bacteriophora infects a wide range of insect hosts with the aid of its mutualistic bacteria Photorhabdus luminescens. While the mutualistic relationship between H. bacteriophora and P. luminescens and the infectivity of the nematode-bacteria complex have been characterized, how nematode fitness is ...

Effect of soil type on infectivity and persistence of the entomopathogenic nematodes Steinernema scarabaei, Steinernema glaseri, Heterorhabditis zealandica, and Heterorhabditis bacteriophora

Journal of Invertebrate Pathology, 2006
We tested the effect of soil type on the performance of the entomopathogenic pathogenic nematodes Steinernema scarabaei, Steinernema glaseri, Heterorhabditis zealandica, and Heterorhabditis bacteriophora. Soil types used were loamy sand, sandy loam, loam, silt loam, clay loam, acidic sand, and a highly organic potting mix.

Heterorhabditis mexicana n. sp. (Rhabditida: Heterorhabditidae) from Tamaulipas, Mexico, and morphological studies of the bursa of Heterorhabditis spp.

Nematology, 2004
Abstract A new species of nematode in the genus Heterorhabditis was found in the northern part of the state of Tamaulipas, Mexico. Morphological and molecular data indicate that this nematode is a new species. The new species is described as Heterorhabditis mexicana n. sp. and is a sister taxon to H.

Compatibility of acaricides with entomopathogenic nematodes (Steinernema and Heterorhabditis)

Nematology, 2017
To expand our knowledge about the compatibility of entomopathogenic nematodes (EPN) to pesticides, we studied the compatibility of EPN infective juveniles (IJ) to five acaricides under laboratory conditions. Four EPN species were used: Steinernema feltiae, S. carpocapsae, S. kraussei and Heterorhabditis bacteriophora.
