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

Effect of extreme temperature on egg development, larval and adult survival of Chordodes nobilii Camerano, 1901 (Gordiida, Nematomorpha) [PDF]

Acta Parasitologica, 2008
On the basis of experimental studies we analyzed the effect of extreme temperatures on the aquatic free-living phases of the life cycle of Chordodes nobilii (Gordiida, Nematomorpha). Bioassays were performed with eggs, larvae, and adults. Eggs and larvae

Gordionus maori (Nematomorpha: Gordiida), a new species of horsehair worm from New Zealand

New Zealand Journal of Zoology, 2018
ABSTRACTOnly four species of freshwater Nematomorpha (Gordiida) and one undetermined Gordius sp. are known from New Zealand. During recent surveys in the South Island we discovered a new species belonging to the genus Gordionus, a genus new to New Zealand. Scanning electron microscopic observations of seven collected specimens revealed that the species

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 ...

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 ...
