Photorhabdus and Xenorhabdus are symbiotic with entomopathogenic nematodes (EPNs) of the genera Heterorhabditis and Steinernema, respectively. These bacteria produce several secondary metabolites including antimicrobial compounds. The objectives of this study were to isolate and identify EPNs and their symbiotic bacteria from Mae Wong National Park, Thailand and to evaluate the antibacterial ac...

Abstract Background Entomopathogenic nematodes (EPNs) have more important role in biological control of economic insect pests. The effect native EPNs on adults the lucerne beetle, Gonioctena fornicata (Brüggemann, 1873) (Coleoptera: Chrysomelidae), and alfalfa weevil, Hypera postica (Gyllenhal, 1813) Curculionidae), which are pests Turkey around world, was investigated. Results Dose-mortality a...

Abstract Background Cabbage butterfly, Pieris brassicae Linnaeus (Lepidoptera: Pieridae), is a major insect pest affecting cole crops worldwide. Excessive applications of chemical-based insecticides have devastating impression over the organisms and environment. Results In this study, entomopathogenic nematode (EPN) Heterorhabditis bacteriophora Poinar strain EUPT-S26 (local isolate) was evalua...

Here, we report the draft genome sequence of Photorhabdus heterorhabditis strain VMG, a symbiont of the entomopathogenic nematode Heterorhabditis zealandica in South Africa. The draft genome sequence is 4,878,919 bp long and contains 4,023 protein-coding genes. The genome assembly contains 262 contigs with a G+C content of 42.22%.

Entomopathogenic nematodes (EPNs) (Rhabditida: Heterorhabditidae and Steinernematidae) are effective biocontrol agents for many insect pests generally stored a period of time prior to their use in the laboratory or field. However, unfavorable storage conditions have great impact on survival infectivity EPNs. This study was conducted determine optimum infective juveniles (IJs) four native EPN sp...

Photorhabdus and Xenorhabdus are the bacterial symbionts of insect pathogenic nematodes, Heterorhabditis Steinernema, respectively. This study aims to characterize from Mizoram, North-east India evaluate their antibacterial potential. The isolates were characterized using recA gyrB gene regions. ethyl acetate extract was tested against strains, viz. Escherichia coli (ATCC 10536), Klebsiella pne...

background and objectives: entomopathogenic nematodes, belonging to the family heterorhabditis and steinernematidae, are reported to be symbiotically associated with specific bacteria and the secondary metabolites produced by these bacteria possess antimicrobial activity. in this study, bacteria were isolated from nematodes belonging to the family rhabditidae, and the antimicrobial activity was...
