Sustainable control of black vine weevil larvae,Otiorhynchus sulcatus(Coleoptera: Curculionidae) withHeterorhabditis bacteriophorain strawberry

Biocontrol Science and Technology, 2008
Efficacy, persistence and recovery of the nematode Heterorhabditis bacteriophora was tested in the laboratory after application of the nematode to strawberry roots by dipping. To mitigate nematode sedimentation and improve attachment to strawberry roots,

Potential of the entomopathogenic nematodes Steinernema feltiae, S. weiseri and Heterorhabditis bacteriophora for the biological control of the sugar beet weevil Bothynoderes punctiventris (Coleoptera: Curculionidae)

Journal of Pest Science, 2008
The sugar beet weevil, Bothynoderes punctiventris Germ. (Coleoptera: Curculionidae), is one of the most damaging pests of sugar beets in Turkey and has been traditionally controlled by application of large amounts of insecticides.

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.

Purification and characterization of an acetylcholinesterase from the infective juveniles of Heterorhabditis bacteriophora

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.

Lipids of in Vivo and in Vitro Cultured Heterorhabditis bacteriophora

Biological Control, 1999
The 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%,

Pheno- and genotyping in vitro dauer juvenile recovery in the nematode Heterorhabditis bacteriophora

Applied Microbiology and Biotechnology, 2023
The entomopathogenic nematode (EPN) Heterorhabditis bacteriophora is an effective biological-control agent of insect pests. The dauer juveniles (DJs) seek for, infect insects, and release cells of the carried symbiotic bacterium of the genus Photorhabdus.

Characterization of SNPs associated with the pathogenesis of Heterorhabditis bacteriophora

2021
Heterorhabditis 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 ...

Liquid media development for Heterorhabditis bacteriophora : lipid source and concentration

Applied Microbiology and Biotechnology, 2000
Lipids are important entomopathogenic nematode nutritional components because they are energy reserves and serve as indicators of nematode quality. The composition and concentration of the media lipid component determine bacterial and nematode yields.

Molecular characterisation of the recovery process in the entomopathogenic nematode Heterorhabditis bacteriophora

International Journal for Parasitology, 2013
In Heterorhabditis bacteriophora, an insect-parasitic nematode, the third juvenile is the infective, developmentally arrested form. When it infects a suitable host, the infective juvenile recovers from developmental arrest and resumes growth and development.

Diet Composition and Lipids of In Vitro-Produced Heterorhabditis bacteriophora

Biological Control, 2001
Abstract Several entomopathogenic nematode species are currently under evaluation for mass production and field efficacy for biological control of insect pests. However, quality and quantity of in vitro -produced entomopathogenic nematodes vary considerably, depending on media, temperature, and production method.
