Carcinops pumilio (Erichson) were collected using two trapping methods: a black light pitfall trap and a mesh-bottomed trap placed on poultry manure. C. pumilio collected with black lights and subsequently starved had a significantly higher dispersal rate during days 1-3 than fully fed groups. When densities of < 500 Caloglyphus berlesei (Michael) (Acarina: Acaridae) per 50 C. pumilio were prov...

Certain mites (Acarina) are parasitic on insects and other arthropods or use them as a means for transport to habitats where they find more suitable environmental conditions. This article reports on phoretic and parasitic mites collected from Diptera in Israel and Egypt. Flies from the families Muscidae, Ceratopogonidae, Sphaeroceridae, Milichiidae, Sepsidae, and Ulidiidae were collected in the...

Little is known about the morphological versatility of the unarmoured dinoflagellates. The morphology of an unarmoured dinoflagellate with a distinctive H-shaped contour is described from sub-surface waters of the Strait of Gibraltar (NEAtlantic) and the northern Philippine Sea (NW Pacific). The cell body was slightly hexagonal with two rounded-tip apical arms and two antapical sharp-pointed ho...

A new species of digenetic trematode and 2 species of ectoparasites from Zalophus wollebaeki Silvertsen, 1953 (Carnivora: Otariidae) in the Galapagos Islands, Ecuador, are reported. These include an eye fluke of Philophthalmus Looss, 1899 (Echinostomata: Philophthalmidae) as well as, to our knowledge, the first report of Antarctophthirus microchir (Trouessart and Neumann, 1888) Enderlein, 1906 ...

Scabies is a skin condition caused by infestation of the mite Sarcoptes scabiei. Sarcoptes scabiei var. hominis is an arthropod member belonging to the order Acarina. Scabies is present throughout the world and is prevalent in all age groups, mostly involving people frequently in contact with animals, children, women, and elderly people. Predisposing factors for scabies include individuals with...

Twelve cell lines representing 10 genera of three orders (Diptera, Lepidoptera, and Orthoptera) of the class Insecta and one cell line (Acarina) from the class Arachnida were examined to discern their sensitivity to the lethal effects of x-irradiation. Radiosensitivity was measured by a combination of colony formation and population growth curve techniques. Each of these arthropod cell lines is...

Studies on the duration of the oviposition and incubation periods of Boophilus decoloratus (Koch, 1844) revealed that these non-parasitic periods are temperature dependent, increase in temperature causing shortening of the periods. Humidity had no effect on duration of either the oviposition or the incubation periods. The relation between the mass of engorged female ticks and that of the eggs t...

The genus Abalakeus Southcott, previously known only from Niger, West Africa, was discovered in China. Abalakeus bambusae Zhang sp. nov. is described from larvae collected on leaves of the moso bamboo (Phyllostachys pubescens) in Fujian.

Two new species of oribatid mites of the family Galumnidae, Allogalumna monodactyla sp. n. and Galumna (Galumna) paracalcicola sp. n., are described from dark loamy soil under crown of Ficus sp. in southern Vietnam. Allogalumna monodactyla sp. n. is the first identified member of Allogalumna recorded for Vietnam. The identification keys to the species of Allogalumna from the Oriental region and...
