Uncovering Nematicidal Natural Products from Xenorhabdus Bacteria

Desalegne Abebew et al.

Summary: This study has identified new nematicidal natural products from Xenorhabdus bacteria, which can provide templates for discovering environmentally safe alternatives to commercially available nematicides. Among the tested natural products, fabclavines, rhabdopeptides, and xenocoumacins showed high toxicity to nematodes.

Metabonomics reveals that entomopathogenic nematodes mediate tryptophan metabolites that kill host insects

Yuan Zhang et al.

Summary: This study investigated the mechanism of how entomopathogenic nematodes kill host insects by producing tryptophan metabolites. The results showed that 3-hydroxyanthranilic acid was highly toxic to the host insects. This study reveals a novel aspect of the infestation mechanism of EPNs.

Txp40, an insecticidal toxin protein from Xenorhabdus nematophila: Purification, toxicity assessment and biophysical characterization

Omkar U. Kinkar et al.

Summary: This study reports the purification, toxicity, and biophysical characterization of the Txp40b toxin from X. nematophila. The recombinant Txp40b exhibits strong toxicity to Galleria mellonella larvae and is found to be an alpha-helix rich protein with a relatively low melting temperature of 45 degrees C. In-silico modeling suggests a two-domain structure for the Txp40b toxin.

Overview of mechanisms and uses of biopesticides

Xiaoman Liu et al.

Summary: Biopesticides have shown to be effective in controlling agricultural diseases and insects. They are sourced from natural products and microorganisms, making them safer for non-target organisms and potentially suitable for organic agriculture. In China, biopesticides like Bacillus thuringiensis, Jinggangmycin, pyrethrins and brassinolide are being developed as alternatives to chemical pesticides.

Intraspecific virulence of entomopathogenic nematodes against the pests Frankliniella occidentalis (Thysanoptera: Thripidae) and Tuta absoluta (Lepidoptera: Gelechiidae)

Raquel Campos-Herrera et al.

Summary: This study evaluated the virulence of different populations of entomopathogenic nematodes (EPN) against two widespread insect pests and found that Steinernema feltiae showed the best results at low concentrations, while Heterorhabditis bacteriophora and Steinernema carpocapsae required higher concentrations for similar or slightly better control effects. The study emphasized the importance of intraspecific variability in EPN virulence.
