Comparative Landmark Analysis of Various Oxyuridae Parasites of Primates and Rodents
1996The 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, 1984Chromosome 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

--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 ...

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.

Annales de parasitologie humaine et comparee, 1983A review of the Oxyurids parasites of Primates shows that most of the species described in the Malagasy Lemurs and in the Old World Monkeys are not single species, but couples of sister-species. The sister-species of each couple may be differentiated sometimes only by the characteristics of male spicule (less evoluated species), sometimes by other ...

The biology of Aspiculuris tetraptera Schultz (Nematoda, Oxyuridae)
1974The following results of field observations and laboratory experiments conducted during a study of the biology of Aspicufuris tetraptera are presented: a) Sex-resistance and age resistance were demonstrated in a survey of the incidence of A. tetraptera in wild populations of its natural host, Mus musculus.
