Toxicity of the herbicide glyphosate to Chordodes nobilii (Gordiida, Nematomorpha)

Chemosphere, 2008
Nematomorpha (horsehair worms) is a poorly known group of worm-like animals similar to nematodes. Adults are free-living and reproduction takes place in freshwater environments, where preparasitic larvae undergo development. All species have a parasitic juvenil stage and infection may result in the host's death, insects being the most frequent host ...

Morphology of Larval Gordius dimorphus (Nematomorpha: Gordiida)

Journal of Parasitology, 2009
Scanning electron microscopy was used to analyze superficial features of Gordius dimorphus Poinar, 1991, larvae that might serve as generic or specific diagnostic characters. Three adults of G. dimorphus (2 males and 1 female) were maintained under laboratory conditions until oviposition, which occurred within long strings commonly referred to as egg ...

Further Evidence for the Absence of Bacteria in Horsehair Worms (Nematomorpha: Gordiidae)

Journal of Parasitology, 2009
We used molecular techniques to characterize bacteria associated with the nematomorph Gordius robustus (Leidy). This worm is a parasite of the fall field cricket, Gryllus pennsylvanicus (Burmeister), which is infected with the symbiotic bacteria, Wolbachia. Because of this close association, our a priori expectation was that G.

Larval survival strategy during winter of Chordodes nobilii Camerano, 1901 (Gordiida, Nematomorpha) [PDF]

open access: yesActa Parasitologica, 2007
AbstractThere are numerous open questions concerning the life cycle of Gordiida (Nematomorpha), especially about egg development and viability of larvae during winter, when the temperature of freshwater environments where they inhabit is low. On the basis of experimental studies we demonstrate that egg development of Chordodes nobilii takes 20–25 days ...

Redescription and new records of freshwater Nematomorpha (Gordiida) from Chile, with the description of two new species

open access: yesRevista Chilena De Historia Natural, 2005
Hasta el momento solo han sido citadas para Chile cuatro especies de Gordiida (Nematomorpha). En este trabajo se describen dos especies nuevas, Gordionus enigmaticus y Gordius austrinus. Gordionus enigmaticus se caracteriza por la variacion en la forma de las areolas a lo largo del surco longitudinal ventral y porque en la region pre-cloacal del ...

Observations on a British hairworm, Parachordodes wolterstorffii (Nematomorpha: Gordiidae)

Journal of Zoology, 1983
Males of the nematomorph Parachordodes wolterstorffi from the New Forest, Hampshire, England have been examined entire, in thick sections and in cuticle preparations by light (differential interference contrast) and scanning electron microscopy. Surface features, internal organization and cuticular fibres are described and illustrated.

Parasitism of Ground Beetles (Coleoptera: Carabidae) by a New Species of Hairworm (Nematomorpha: Gordiida) in Arctic Canada

Journal of Parasitology, 2016
The host-parasite associations between ground beetles (Coleoptera: Carabidae) and hairworms (Nematomorpha: Gordiida) collected from the Arctic (an understudied and ecologically important region) is described. Carabids and their parasites were collected from 12 sites spanning the 3 northernmost ecoclimatic zones of Canada (north boreal, subarctic, and ...

Validation test with embryonic and larval stages of Chordodes nobilii (Gordiida, Nematomorpha): Sensitivity to three reference toxicants

Chemosphere, 2010
Chordodes nobilii is a parasite whose pre- and postparasitic stages are found in different types of freshwater bodies. Due to the peculiarities of its life cycle, it acts as a link between freshwater bodies and terrestrial ecosystems. There is little toxicological information on the group Gordiida. It is only known that embryos and larvae of C. nobilii
