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 ...

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.

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, 2017To 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.

Lipids of in Vivo and in Vitro Cultured Heterorhabditis bacteriophora
Biological Control, 1999The lipid, sterol, and fatty acid compositions of Heterorhabditis bacteriophora infective juveniles reared by in vivo and in vitro methods (Galleria mellonella, Popillia japonica, solid and liquid culture) were compared. The greatest accumulation of lipids per dry weight was achieved by growing nematodes in P. japonica and solid culture (54.7 and 60.3%,

Studies On Temperature Limitations To Heterorhabditis Heliothidis Activity
Nematologica, 1987Temperature limitations to the activity of a strain of H. heliothidis were studied using G. mellonella as a host in a temperature gradient incubator. The maximum temperature at which host death was caused by the nematode was 32.3°C and the minimum 11-12°C. The optimum temperature for activity was approximately 28°C.

Comparative Biochemistry and Physiology Part C: Toxicology & Pharmacology, 2007
Acetylcholinesterases (AChEs) have been estimated in the infective juveniles (IJs) of eight different strains of heterorhabditid nematodes. The enzyme content ranged from 45.6 to 421.3 units/10(5) IJs with specific activity 34.0 to 82.6 units/mg protein. The isoenzyme patterns revealed the existence of two-slow-moving isoforms.

Characterization of SNPs associated with the pathogenesis of Heterorhabditis bacteriophora
2021Heterorhabditis bacteriophora belongs to the Heterorhabditis genera of entomopathogenic nematodes (EPN) that hosts a symbiotic relationship with the entomopathogenic bacteria Photorhabdus (Kenney et al., 2019). The EPNs are capable of independently killing their insect host through a class of bioactive molecules called Excretory or Secreted proteins ...
