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 ...

Entomopathogenic nematodes are potent biopesticides that can be mass-produced by in vitro or in vivo methods. For in vivo production, consistently high infection rates are critical to efficiency of the process. Our objective was to optimize in vivo inoculation of Steinernema carpocapsae and Heterorhabditis bacteriophora in Galleria mellonella and Tenebrio molitor by determining effects of inocu...

Heterorhabditis bacteriophora Project Summary: This project aims to sequence the genome of the entomopathogenic nematode Heterorhabditis bacteriophora strain TTO1 as a representative of 45 other species that are used as biological control agents for insect pests worldwide. This nematode is closely related to the two already sequenced free-living nematodes, Caenorhabditis elegans and C. briggsae...

A simple null model, particularly germane to small and vulnerable organisms such as parasites, is that local conditions set a stage upon which larger-scale dynamics play out. Soil moisture strongly influences survival of entomopathogenic nematodes (EPN), which in turn drive trophic cascades by protecting vegetation from root-feeding herbivores. In this study, we examine the mechanisms responsib...

Understanding the desiccation survival attributes of infective juveniles of entomopathogenic nematodes (EPN) of the genera Steinernema and Heterorhabditis, is central to evaluating the reality of enhancing the shelf-life and field persistence of commercial formulations. Early work on the structural and physiological aspects of desiccation survival focused on the role of the molted cuticle in co...
