The Pasteuria group of Gram positive bacteria are invertebrate parasites with the potential to be developed into biological control agents of plant-parasitic nematodes. A key step in the infection process is the attachment of endospores to the cuticle of plant-parasitic nematodes, possibly through a Velcro-like attachment system involving the collagen-like fibres of the exosporium (Davies, 2009...

Wolbachia is an endosymbiotic bacterium widely present in arthropods and animal-parasitic nematodes. Despite previous efforts, it has never been identified in plant-parasitic nematodes. Random sequencing of genes expressed by the burrowing nematode Radopholus similis resulted in several sequences with similarity to Wolbachia genes. The presence of a Wolbachia-like endosymbiont in this plant-par...

Primary and secondary types housed in the Canadian National Collection of Nematodes are given for 396 species of plant-parasitic, marine, freshwater, terrestrial, and entomophagous nematodes. Species are listed in alphabetical order and include author(s), date, publication source, type category, numbers and sex, and collection accession number. Current nomenclatorial changes in status of a bino...

Introduction Nematodes are tiny, worm-like, multicellular animals adapted to living in water. The number of nematode species is estimated at half a mil lion, many of which are “free-living” types found in the oceans, in freshwater habitats, and in soils. Plant-parasitic species form a smaller group. Nematodes are common in soils all over the world (Dropkin, 1980; Yepsen, 1984). As a commentator...

Plant parasitic nematodes (PPN) are known to survive periods of desiccation, an ability that increases the risk of them surviving unintentional transport between countries. To investigate nematode survival in soil subject to prolonged storage, soil collected from a native forest and an organic orchard was stored separately in cupboards at ambient temperature for 36 months. Subsamples were taken...

In this study, we aimed to determine the nematode diversity in soils from olive orchards İzmir, Manisa, Çanakkale, and Balıkesir provinces. For purpose, a survey was carried out 2021-2022; each orchard, soil samples were collected 0-60 cm depth, nematodes extracted by modified Baermann Funnel method. Thirty-seven genera of (Achromodora, Acrobeles, Acrobeloides, Alaimus, Aphelenchus, Aphelenchoi...

Insulin-like (ins) peptides play an important role in development and metabolism across the metazoa. In nematodes, these are also required for dauer formation and longevity and are expressed in different types of neurons across various life stages which demonstrate their role in parasites and could become possible targets for parasite control. To date, many nematode genomes are publically avail...
