The Systematics and Evolution of Pinworms (Nematoda: Oxyurida: Thelastomatoidea) from Invertebrates

Journal of Parasitology, 2014
The nematode order Oxyurida is unique in including species for which definitive host ranges are broad and may include vertebrate or invertebrate hosts. The superfamily Thelastomatoidea is a highly diverse assemblage of oxyurids occurring in cockroaches, diplopods, hydrophilid beetles, passalid beetles, several other coleopteran larvae, mole crickets ...

Evolutionary Biology of the Oxyurida (Namatoda): Biofacies of a Haplodiploid Taxon

1989
Publisher Summary This chapter reviews the phylogeny, life history, and ecology of Oxyurida to gain a fuller understanding of the biofacies of haplodiploidy. Members of Oxyurida, the so-called pinworms, were among the first nematodes known to man. Because much early work in parasitology concentrated on life cycles, many of them indirect, oxyuridans ...

Oxyurida-Enterobius Vermicularisenterobiasis Or Oxyuriasis

1999
Abstract The family Oxyuridae, has the order Oxyurida, which contains two genera with parasitic species in humans: Enterobius and Syphacia. The most important species is E. vermicularis, referred to commonly as pinworm because of the characteristic needle-like posterior end of the female. Another species, E.

Observations on the genus Indiana Chakravarty, 1943 (Oxyurida: Pulchrocephalidae)

Systematic Parasitology, 1983
Indiana gryllotalpae is redescribed from the gut of a mole-cricket, Scapteriscus sp., from Trinidad. The structure of the cephalic umbraculum (comprising 6 major and 6 minor cuticular elements extending back from the setulose lip region) is described in detail by use of both light and scanning electron microscopy. I.

Transmission Pattern and Intraspecific Competition as Determinants of Population Structure in Pinworms (Oxyurida: Nematoda)

The Journal of Parasitology, 1992
The transmission pattern of Zonothrix columbianus (Nematoda: Oxyurida) in its host Tropisternus columbianus (Coleoptera: Hydrophilidae), an aquatic beetle, was studied to determine whether parasites were dispersed with their hosts and to examine the possible role of intraspecific competition in limiting population size.

Comparative Landmark Analysis of Various Oxyuridae Parasites of Primates and Rodents

1996
The patterns of shape variation in the caudal bursa of males of various species of pinworms were analyzed using geometric morphometric methods. Thirty-four of a group of 45 oxyurid species that are primarily parasitic on primates, and are considered to constitute a monophyletic group, were studied.

[Haplodiploidy of Oxyurida. Effects of this phenomenon in the life cycle].

Annales de parasitologie humaine et comparee, 1984
Chromosome behavior during gametogenesis and early cleavage is studied in two species of Thelastomatidae (Oxyurida), Hammerschmidtiella sp. and Thelastoma sp., parasites of diplopods. Both species are shown to be haplodiploid: male with 4 Thelastoma) or 5 (Hammerschmidtiella) chromosomes and double this number in the corresponding female. Haplodiploidy

[Redescription of Helminthoxys tiflophila and consideration of the systematics of Oxyuridae parasites of rodents].

Annales de parasitologie humaine et comparee, 1983
--Morphology--Helminthoxys tiflophila (Vigueras, 1943) parasite in Capromys prehensilis (Caviomorpha, Rodent) is redescribed. In the males of this species occurs a peculiar type of ventral cuticular swellings. The adherence with cuticula of females is not obtained by hooking, but by gluing: a ventral hypodermal secretion coagulates on surface of ...

On Artigasia horridospina n.sp., Longior semialata n.sp., Mentecle magnifica n.sp., Paraxyo ensicrinatus n.sp. (Oxyurida: Hystrignathidae) and Pulchrocephala? pulchrocephala Travassos, 1925 (Oxyurida: Pulchrocephalidae)

Systematic Parasitology, 1981
Four new species of hystrignathid nematodes are described from the midgut caeca of Passalus unicornus (Coleoptera: Passalidae) from St. Lucia, West Indies.

Haplodiploidy in Aspiculuris tetraptera (Nitzch) (Heteroxynematidae) and Syphacia obvelata (Rudolphi) (Oxyuridae), nematode (Oxyurida) parasites of Mus musculus

Canadian Journal of Zoology, 1984
Cytological aspects of gametogenesis are studied in the common oxyuroid (Nematoda) parasites of Mus musculus, Syphacia obvelata (Oxyuridae) and Aspiculuris tetraptera (Heteroxynematidae). Both species are shown to be haplodiploid: males develop from unfertilized eggs and are haploid and females develop from fertilized eggs and are diploid. In female A.
