Parasitic and phoretic arthropods of the elephant-eared and the Santa Cruz kangaroo rats.

The parasitic and phoretic arthropods of the elephant-eared kangaroo rat (Dipodomys elephantinus) and Santa Cruz kangaroo rat (D. venustus) are reported; most of these represent new host records. Thirteen of 14 (93%) of D. elephantinus and 11 of 12 (92%) of D. venustus had 11 and nine arthropod species, respectively. Larval and nymphal stages of the tick Dermacentor occidentalis were the most prevalent parasite (77%) on D. elephantinus whereas the mesostigmatid mite Androlaelaps fahrenholzi was the most prevalent (56%) on D. venustus. The arthropod fauna of these two closely related rodents were similar with seven of the 14 arthropod species occurring on both host species. Two species of the host specific listrophorid mite of the genus Geomylichus were found on both hosts.

Exotic ectoparasites of ostriches recently imported into the United States.

Eleven species of ectoparasitic arthropods were collected and identified from ostriches (Struthio camelus) recently imported into the United States from Africa and Europe. Four of these species are reported from ostriches for the first time. The parasites included adult hippoboscid flies (Struthiobosca struthionis) and 10 species of adult ixodid ticks (Amblyomma gemma, A. lepidum, A. variegatum, Haemaphysalis punctata, Hyalomma albiparmatum, H. luscitanicum, H. marginatum rufipes, H. truncatum, Hyalomma sp., and Rhipicephalus turanicus. As a result of these findings, the U.S. Department of Agriculture prohibited further importation into the United States of ostriches and other flightless birds on an interim basis.

Epizoic fauna of Plecotus mexicanus (Chiroptera: Vespertilionidae) in Tlaxcala, Mexico.

Four hundred nineteen arthropod ectoparasites were taken from Plecotus mexicanus (Vespertilionidae) collected in the state of Tlaxcala, Mexico: the insects Trichobius corynorhini Cockerell (Diptera: Streblidae) and Myodopsylla collinsi Kohls (Siphonaptera: Ischnopsyllidae) and the mites Macronyssus longisetosus (Furman) and M. unidens Radovsky (Macronyssidae), Spinturnix sp. (Spinturnicidae), Pteracarus elegans Dusbádek & Wilson and Acanthophthirius (Myotimyobia) sp. (Myobiidae), and Whartonia glenni Brennan (Trombiculidae). P. mexicanus is reported in the state of Tlaxcala for the first time. This is the first survey of ectoparasites of this bat, and all parasite associations with P. mexicanus are new host records as well as new range records for Tlaxcala. This is the first report from Mexico; it records a major southern extension of the ranges of M. longisetosus, M. unidens, and P. elegans. The genus Acanthophthirius is also reported in Mexico for the first time.

Estimation of postmortem interval by arthropod succession. Three case studies from the Hawaiian Islands.

Three instances of estimation of postmortem interval using computer-assisted entomological techniques on the island of Oahu in the Hawaiian Islands are presented. While postmortem intervals were similar for all cases (4-5 1/2 days), recovery of the remains in differing habitats (xerophytic, mesophytic, and swamp) on the island resulted in significant differences in gross appearance of the remains, which could have resulted in the determination of different postmortem intervals in the absence of entomological techniques.

The prevalence of helminth and arthropod parasites of warthog, Phacochoerus aethiopicus, in South West Africa/Namibia.

A total of 38 warthog, Phacochoerus aethiopicus, shot on a farm in northern South West Africa/Namibia were examined for internal and external parasites at monthly intervals over a period of 13 months. They harboured cestodes, 9 nematode species, 6 ixodid tick species and 1 species each of an argasid tick, a flea, a louse and larvae of a dipteran fly. Clear patterns of seasonal abundance could be determined only for the spirurid stomach worm, Physocephalus sexalatus, and the sucking louse, Haematopinus phachoeri.

[Generalized and lethal pentastomiasis due to Armillifer grandis (Hett, 1915)]. / Pentastomose généralisée et mortelle à Armillifer grandis (Hett, 1915).

The authors described a case of generalised and lethal Pentastomiasis by a five years old girl. The most heavy parasitised organs are the lungs and the brain. Considering the age of the child and the uncommon density of the parasites, the authors suggest that the symptoms may follow the casual ingestion of a gravid female worm.
