Summary: Plant-parasitic nematodes are significant pests for many crops worldwide. Fluazaindolizine, a fluorinated nematicide, shows strong toxic activity against certain nematode species with low mammalian toxicity. The compound impacts nematode parasitism at non-lethal concentrations and short-term exposure.

Summary: The root-knot nematode Meloidogyne incognita adapts rapidly to unfavorable conditions through epigenetic mechanisms, impacting gene expression and sharing similar epigenetic signatures with the model nematode Caenorhabditis elegans. The H3K4me3 histone modification is strongly correlated with high expression of genes during specific developmental stages, providing insights into the dynamic regulation of parasitism genes.

Summary: Fluopyram is a highly effective and selective inhibitor of succinate dehydrogenase in plant-parasitic nematodes. It impairs ATP generation, causing paralysis in nematodes. Fluopyram shows different efficacy against different PPN species, possibly due to amino acid differences in the SDHC gene.

Summary: This review focuses on exploring safe and effective alternative methods to minimize yield losses caused by plant-parasitic nematodes (PPNs), including biologicals, botanicals, non-host crops, and modern techniques. It provides an overview of the interactions with other biotic and abiotic factors for PPN management, evaluates specific production practices, and suggests optimizing gains from PPN control mechanisms. The review also emphasizes the importance of agricultural conservation practices to address issues related to the reliability and slow activity of biologicals against PPNs.

Summary: Wolbachia symbionts are successful host-associated microbes that infect arthropods and nematodes. This study discovered a highly divergent strain of Wolbachia in an insect-parasitic nematode, Howardula sp., which was not previously known to harbor Wolbachia. The genome of this Wolbachia strain is highly reduced and smaller than other known Wolbachia genomes, but it has retained genes related to haem biosynthesis.

Summary: The study found that using 1,3-dichloropropene was more effective in suppressing reniform nematode densities compared to aldicarb and the non-treated control, but did not increase cotton yield. Application of 1,3-dichloropropene promoted plant growth, resulting in higher plant biomass and plant height. There were no significant differences in response to nematicides between the two cotton cultivars.

Summary: This study investigated plant-parasitic nematodes affecting greenhouse vegetables, finding Meloidogyne, Helicotylenchus, and Pratylenchus to be the most common genera, while onions were not infected. The results indicate that soil properties are as important as host plants for the abundance, distribution, and structure of nematode communities, potentially aiding in improving vegetable pest control.

Summary: This study reveals the crucial role of AUXIN RESPONSIVE FACTOR8 (Arf8) gene in the development of the feeding site induced by root-knot nematodes in tomato. The expression level of Arf8 gene is associated with nematode infection and it participates in the formation of the feeding site through regulating the plant hormone signaling pathway.

Summary: The study found that changes in sterols in important crops after infection with Meloidogyne incognita mainly manifest as a change in the beta-sitosterol/stigmasterol ratio, particularly an increase in beta-sitosterol and a decrease in stigmasterol in tomato, soybean, cucumber, and corn. Cholesterol levels increased in tomato, cucumber, and corn, while being often undetectable in uninfected plants. The expression of the sterol 22C-desaturase gene CYP710A11 in tomato was found to be consistent with the sterol profile after M. incognita infection, providing new insights into plant-nematode interactions.

Summary: Mermithid nematodes have been found to be widespread invertebrate parasites, with 16 new fossils indicating their presence in mid-Cretaceous insects and their important role in the terrestrial ecosystem during that time. Interestingly, some hosts previously unknown to be parasitized by these nematodes were also discovered.

Summary: Fungal volatile organic compounds (VOCs), particularly 1-Octen-3-ol, are highly toxic to root-knot nematodes and show potential as ecofriendly alternatives to synthetic nematicides. Exposure to 1-Octen-3-ol and 3-Octanone resulted in high mortality rates of the nematodes, with 1-Octen-3-ol exhibiting greater nematicidal activity than 3-Octanone.

Summary: A novel nematotoxic cytolytic (Cyt)-like protein was successfully purified from the entomopathogenic fungus Conidiobolus obscurus via heterologous expression in Escherichia coli. This protein showed high nematicide activity against B. xylophilus, significantly impacting the nematode's vitality and fecundity, suggesting its potential for controlling B. xylophilus.

Summary: The fungus gnat Bradysia impatiens is attracted to the oyster mushroom Pleurotus ostreatus, with both males and females showing a preference for the Mucor circinelloides fungal strain over Aspergillus flavus. Female adults demonstrated the strongest attraction to the fungal strains, indicating potential for using M. circinelloides in a push-pull strategy for biocontrol in edible mushroom cultivation.

Summary: This paper presents a new protocol for studying the ppm-1 gene in the pinewood nematode, B. xylophilus, using RNA interference (RNAi). The authors successfully delivered double-stranded RNA (dsRNA) to the nematodes and observed the effects of RNAi on gene expression and phenotypes. This research is important for advancing our understanding of gene functions in B. xylophilus and other parasitic nematodes, and it has implications for developing genetic engineering-based control strategies.

Summary: The study investigates the total putative long noncoding RNAs (lncRNAs) in an aphid-obligate pathogen, Conidiobolus obscurus, and their involvement in virulence attenuation. Various differentially expressed lncRNAs and protein-coding genes related to virulence decline were identified, with functional enrichment analysis showing involvement in peptidase activity, protein folding, autophagy, and metabolism. Target prediction analysis revealed lncRNAs possibly regulating virulence-related genes, indicating a link between lncRNAs and environmental stress response in C. obscurus.
