Characterization of symbiotic and associated bacteria from entomopathogenic nematode Heterorhabditis sp. (nematode: Heterorhabditidae) isolated from India [PDF]

Egyptian Journal of Biological Pest Control, 2020
Background Entomopathogenic nematodes (EPNs) harboring symbiotic bacteria are one of the safest alternatives to the chemical insecticides for the control of various insect pests.

Multi-locus phylogenetic analyses uncover species boundaries and reveal the occurrence of two new entomopathogenic nematode species, Heterorhabditis ruandica n. sp. and Heterorhabditis zacatecana n. sp. [PDF]

Journal of Nematology, 2021
Abstract Species of the nematode genus Heterorhabditis are important biological control agents against agricultural pests. The taxonomy of this group is still unclear as it currently relies on phylogenetic reconstructions based on a few genetic markers with little resolutive power, specially of closely related species.

Biocontrol potential of naturally occurring entomopathogens against Maladera formosae in corn-soybean rotated systems. [PDF]

Pest Manag Sci
We isolated three insect‐killing nematodes from Maladera formosae infested corn–soybean rotated fields, Heterorhabditis bacteriophora, Pristionchus sp., and Steinernema carpocapsae. Results from greenhouse and field microcosm studies indicate all three nematodes can infect and kill M. formosae grubs and persist through winter.

Photorhabdus viridis sp. nov. Isolated from Heterorhabditis zealandica Entomopathogenic Nematodes. [PDF]

Curr Microbiol
AbstractA novel bacterial species, Photorhabdus viridis sp. nov., represented by strain GreenT, isolated from Heterorhabditis zealandica MJ2C entomopathogenic nematodes, is described. Phylogenetic reconstructions using 16S rRNA gene sequences show that strain GreenT is closely related to P. thracensis DSM 15199 T. The 16rRNA gene sequences of these two

Virulence and biocontrol potential of entomopathogenic nematodes against soil-dwelling stages of the small hive beetle under laboratory and semi-field conditions. [PDF]

Pest Manag Sci
Entomopathogenic nematodes (EPNs) are virulent against multiple life stages of Aethina tumida in the laboratory. EPNs significantly reduce adult emergence in natural and autoclaved sterile soil under semi‐field glasshouse conditions. Abstract BACKGROUND The small hive beetle (SHB; Aethina tumida) is a significant pest affecting honey bees and the ...

Fatty acid composition of Heterorhabditis sp. during storage [PDF]

Comparative Biochemistry and Physiology Part B: Biochemistry and Molecular Biology, 1999
The fatty acid composition of three North West European isolates of Heterorhabditis sp. from different geographical origins, UK211 (England), HF85 (The Netherlands) and EU17 (Estonia) was assessed directly after harvest and, for UK211 and HF85, after 5 weeks storage in water at 20 degrees C. Lipid represented 34-43% of the dry weight of fresh nematodes.

Photorhabdus africana sp. nov. isolated from Heterorhabditis entomopathogenic nematodes. [PDF]

Curr Microbiol
AbstractOne Gram-negative, rod-shaped bacterial strain, isolated from an undescribed Heterorhabditis entomopathogenic nematode species was characterized to determine its taxonomic position. The 16S rRNA gene sequences indicate that it belongs to the class Gammaproteobacteria, to the family Morganellaceae, to the genus Photorhabdus, and likely ...

Photorhabdus heterorhabditis subsp. aluminescens subsp. nov., Photorhabdus heterorhabditis subsp. heterorhabditis subsp. nov., Photorhabdus australis subsp. thailandensis subsp. nov., Photorhabdus australis subsp. australis subsp. nov., and Photorhabdus aegyptia sp. nov. isolated from Heterorhabditis entomopathogenic nematodes

International Journal of Systematic and Evolutionary Microbiology, 2021
Three Gram-stain-negative, rod-shaped, non-spore-forming bacteria, BA1T, Q614T and PB68.1T, isolated from the digestive system of Heterorhabditis entomopathogenic nematodes, were biochemically and molecularly characterized to clarify their taxonomic affiliations.
