Nematode Parasites and Associates of Ants: Past and Present

open access: yesPsyche: A Journal of Entomology, Volume 2012, Issue 1, 2012., 2012
Ants can serve as developmental, definitive, intermediate, or carrier hosts of a variety of nematodes. Parasitic ant nematodes include members of the families Mermithidae, Tetradonematidae, Allantonematidae, Seuratidae, Physalopteridae, Steinernematidae, and Heterorhabditidae.

Coelomocytes: Biology and Possible Immune Functions in Invertebrates with Special Remarks on Nematodes

open access: yesInternational Journal of Zoology, Volume 2009, Issue 1, 2009., 2009
All metazoans are exposed to a wide range of microbes and have evolved complex immune defenses used to repel infectious agents. Coelomocytes play a key role in the defense reactions of most invertebrates. They are involved in important immune functions, such as phagocytosis, encapsulation, graft rejection, and inflammation, as well as the synthesis and

Organic mulching modulated native populations of entomopathogenic nematode in vineyard soils differently depending on its potential to control outgrowth of their natural enemies [PDF]

open access: yes, 2022
The entomopathogenic nematodes (EPNs) are biological control agents that are widespread in crop soils. However, traditional agricultural management practices such as cultivation and agrochemical usage can alter the soil balance that enables their ...

Symmetry breakage in the development of one-armed gonads in nematodes [PDF]

open access: yes, 1996
Whereas the hermaphrodite gonad of Caenorhabditis elegans has two symmetric arms (didelphy), the female/hermaphrodite gonad of many nematode species features a single anterior arm (monodelphy).

Isolation and Identification of Nematode‐Infecting Microsporidia

open access: yesCurrent Protocols, Volume 4, Issue 5, May 2024.
Abstract Nematodes are naturally infected by the fungal‐related pathogen microsporidia. These ubiquitous eukaryotic parasites are poorly understood, despite infecting most types of animals. Identifying novel species of microsporidia and studying them in an animal model can expedite our understanding of their infection biology and evolution.

New information on insect nematodes from Iran: report of Distolabrellus veechi (Nematoda: Mesorhabditidae) as new species and male of Oscheius tipulae (Nematoda: Rhabditidae) [PDF]

open access: yesنامه انجمن حشره‌شناسی ایران
In order to identify nematodes associated with insects in the forested areas of Guilan province, Iran, soil, wood, and insect samples were collected. Nematodes were extracted using the insect-baiting method, and the obtained specimens were analyzed based

Control of Vulval Cell Division Number in the Nematode Oscheius/Dolichorhabditis sp. CEW1 [PDF]

open access: yes, 2001
Spatial patterning of vulval precursor cell fates is achieved through a different two-stage induction mechanism in the nematode Oscheius/Dolichorhabditis sp. CEW1 compared with Caenorhabditis elegans.

Analysis of winter diet in Guizhou golden monkey (Rhinopithecus brelichi) using DNA metabarcoding data

open access: yesEcology and Evolution, Volume 14, Issue 2, February 2024.
Our DNA metabarcoding analysis has revealed that Rhinopithecus brelichi predominantly feeds on plants from the Magnoliaceae and Rubiaceae families, Diptera and Coleoptera insects, as well as macrofungi such as Agaricales throughout the winter season. Abstract The Guizhou golden monkey (Rhinopithecus brelichi) is a critically endangered wildlife species,

Polymorphism and evolution of vulval precursor cell lineages within two nematode genera, Caenorhabditis and Oscheius [PDF]

open access: yesCurrent Biology, 2001
The cell lineage of nematodes is mostly invariant for a given species, but varies between species. One can thus wonder how a cell lineage varies during evolution. We have started a microevolutionary approach within two genera by observing lineage variations of vulval precursor cells in different natural nematode populations of the same and closely ...

Normalization and centering of array-based heterologous genome hybridization based on divergent control probes [PDF]

open access: yes, 2011
Background: Hybridization of heterologous (non-specific) nucleic acids onto arrays designed for model-organisms has been proposed as a viable genomic resource for estimating sequence variation and gene expression in nonmodel organisms.
