Physiological ageing and behavioural plasticity of Heterorhabditis bacteriophora infective juveniles
Nematology, 2002AbstractHeterorhabditis bacteriophora is a cruiser strategist that exhibits long distance ranging searches for insect hosts in soil. We characterised age-based variations in constituent behaviours and total lipid reserves of laboratory-aged H. bacteriophora infective juveniles. Individuals demonstrated extensive behavioural variability within the first

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%,

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 ...

Susceptibility of Phytodecta fornicata (Coleoptera: Chrysomelidae) to Heterorhabditis bacteriophora
2013The infectivity of Heterorhabditis bacteriophora for adult stage of Phytodecta fornicata was evaluated in the laboratory. Two different nematode concentrations (1000 and 2000 infective juveniles [IJs] per adult) were tested at temperatures 30 and 22°C.

The present study was aimed at determining the influence of various environmental factors on sex differentiation (SD) in the entomopathogenic nematode Heterorhabditis bacteriophora HP88 strain, under in vivo and in vitro culture conditions. Injection of individual nematodes into last instars of Galleria mellonella resulted in development of a similar ...

Parasitism of the mosquito Culex pipiens by the nematode Heterorhabditis bacteriophora
Journal of Invertebrate Pathology, 1982Abstract Various concentrations of the nematode Heterorhabditis bacteriophora were added to dishes containing second, third, and fourth larval instars of the mosquito, Culex pipiens, respectively. The infective stage nematodes were ingested by the mosquito larvae, they then penetrated through the alimentary tract in the neck region and entered the ...
