Development of biotools for vineyard-associated pest and disease control based on entomopathogenic nematode symbiotic bacteria
… of entomopathogenic nematodes, specifically Xenorhabdus spp. and Photorhabdus spp., emerge as potential biocontrol agents due to their ability to produce bioactive compounds with insecticidal and antifungal properties. We hypothesized that these symbiotic bacteria and their by-products might …

Nutrition modulates the interaction between the bacterium Xenorhadbus nematophila and its lepidopteran host Spodoptera littoralis
… Noctuidae) and its natural pathogen Xenorhabdus nematophilus (Enterobacteriaceae) as a model system, this thesis investigates the influence of host nutrition on pathogen virulence and host resistance/tolerance. Findings confirmed the role of dietary protein intake on S. littoralis …

Study of PVCA and PVCB, two enzymes involved in making isonitrile-containing natural products in bacterial pathogens
… homologous proteins from Pseudomonas aeruginosa, Xenorhabdus nematophila and Erwinia amylovora were characterized and compared. Recombinant PvcB proteins were heterologously expressed and purified to homogeneity. Catalytic activities of three PvcB enzymes were evaluated in the presence of the …

Co-existence and niche separation of two subspecies of Photorhabdus temperata associated with Heterorhabditis downesi in a dune grassland
… bacteria from the genera Photorhabdus and Xenorhabdus, respectively. Previous studies showed that Heterorhabditis downesi was associated with two different colour variants (pur and yel) of its Photorhabdus bacterial symbiont in sand dunes on North Bull Island in Dublin Bay, with evidence of …

Non chemical alternatives for pest management: Entomopathogenic nematodes and UV-C light
The primary objectives of this research are to determine effective biological and alternative control strategies of insect and disease pests in order to reduce harsh chemical use during greenhouse crop production and transport s. This research includes two separate studies: 1) testing the practical …
