Molecular characterizations of the entomopathogenic nematodes, Heterorhabditis bacteriophora and Oscheius myriophilus from Iraq

Egyptian Journal of Biological Pest Control, 2019
A survey was conducted in three main regions of Iraq to isolate and identify entomopathogenic and insect parasitic nematodes. Soil samples were collected from 15 sites across 3 provinces from grassland, date palm, and citrus fields, and tested for the ...

Potential of entomopathogenic nematodes of the genus Heterorhabditis for the control of Stomoxys calcitrans (Diptera: Muscidae)

Revista Brasileira de Parasitologia Veterinária, 2017
The present study verified the pathogenic potential of entomopathogenic nematodes (EPNs) of the genus Heterorhabditis (Heterorhabditis bacteriophora, isolate HP88 and Heterorhabditis baujardi isolate LPP7) to immature stages of Stomoxys calcitrans in the

Glucosinolate hydrolysis products suppress entomopathogenic nematodes in vitro but do not protect sequestering flea beetle larvae in vivo. [PDF]

Pest Manag Sci
The flea beetle's glucosinolate‐based chemical defense fails to protect larvae from nematode infection. However, the defense inhibits the nematode's symbiotic bacteria, thereby potentially impairing nematode reproduction and biocontrol success. Abstract BACKGROUND The efficacy of entomopathogenic nematodes (EPNs) in the biological control of insect ...

How effective are entomopathogenic nematodes for vine weevil (Coleoptera: Curculionidae) biological control? A meta-analysis. [PDF]

Pest Manag Sci
Entomopathogenic nematodes provide reliable biological control of vine weevil larvae, reducing populations by 63% on average. All five tested species are effective, with temperature (18–30 °C) being the strongest predictor of success. Abstract BACKGROUND Vine weevil (Otiorhynchus sulcatus) is a globally important pest of soft fruit and ornamental crops

Basic laboratory and field manual for conducting research with the entomopathogenic nematodes, Steinernema and Heterorhabditis, and their bacterial symbionts

Turkish Journal of Zoology, 2022
: Broad spectrum chemical pesticides are harmful to humans and other nontarget organisms. Biological control, which entails the use of natural enemies, is a viable alternative.

Structural and functional characterization of the newly identified Photorhabdus laumondii tumor necrosis factor-like lectin. [PDF]

FEBS J
We characterize the PLTL lectin from Photorhabdus laumondii, which adopts a unique TNF‐like fold. Binding assays reveal a preference for branched histo‐blood group oligosaccharides. Protein crystallography uncovers a novel hexameric assembly and identifies key residues involved in carbohydrate recognition.

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.

Journal of nematology, 2021
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 ...

Ecological characterisation of the Colombian entomopathogenic nematode Heterorhabditis sp. SL0708 [PDF]

Brazilian Journal of Biology, 2013
The entomopathogenic nematode Heterorhabditis sp. SL0708 (Rhabditida: Heterorhabditidae) isolated from soil in Alcalá, Valle del Cauca (Colombia) was characterised ecologically using Galleria mellonella larvae (L) (Pyralidae: Galleriinae) as hosts.

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 ...
