Vacuum Sampling for Psoroptes ovis (Acari: Psoroptidae)
Journal of Medical Entomology, 1987An improved system of vacuum sampling using a modified household vacuum cleaner was compared with standard skin scraping to detect covert to light populations of Psoroptes ovis (Hering) on cattle.

Genetic Differentiation of Mites of the Genus Chorioptes (Acari: Psoroptidae)
Experimental & Applied Acarology, 1999In an effort to clarify the species status of mites of the genus Chorioptes the second internal transcribed spacer of the rRNA gene was characterized in 14 isolates from cattle, horse, sheep and llama of different geographic origins. The genotypes segregated into two clearly separated groups of DNA sequences.

Chorioptic Mange (Acarina: Psoroptidae) in Domestic and Wild Ruminants in Israel
Experimental & Applied Acarology, 1999In a 20-year-survey, 9364 dairy cattle in 324 herds kept under a zero-grazing management, 1252 beef cattle in 46 herds grazing all the year round, 3347 sheep in 134 herds (only 26 are grazing herds), and 872 goats in 47 herds (only 20 are grazing) were examined.

Maintaining Psoroptes ovis (Acari: Psoroptidae) off-host in the laboratory
Experimental and Applied Acarology, 2007Feeding and maintaining sheep scab mites off-host is an important step towards achieving a safer, environmentally-friendly means of controlling sheep scab disease. The test arena developed by Thind and Muggleton (Exp Appl Acarol 22:543-552, 1998) has been adapted for feeding and maintaining Psoroptes ovis off-host.

Precopulatory Pairing and Mating of Psoroptes Mites (Acari: Psoroptidae)
Journal of Medical Entomology, 1983Adult males of 2 species of Psoroptes formed attachment pairs with both nymphal stages of the female. However, more female nymphs of both species were paired while in the tritonymph stage than as protonymphs. This attachment behavior is compared to the “guarding” behavior of male Tetranychus mites on female deutonymphs.

A review of the genus Listropsoralges (Acari, Psoroptidae) with the descriptions of two new species
Acta Parasitologica, 2009AbstractMites of the genus Listropsoralges permanently parasitizing New World marsupials of the family Didelphidae are revised. An emended diagnosis of this genus, descriptions of the new species L. caluromys sp. nov. and L. faini, and a key to species based on males are provided.

Influence of Psoroptes ovis (Hering) (Acari: Psoroptidae) on the Performance of Beef Steers
Journal of Economic Entomology, 1984Forty-eight Hereford steers were used to determine the effects of Psoroptes avis (Hering) infestations on weight gain, feed conversion, and feed intake. Calves were randomly assigned to six pens with three pens per treatment. No calves were infected in the control pens, whereas two calves in each of the infested pens were initially exposed to P.

Population increase of Psoroptes ovis (Acari: Psoroptidae) on stanchioned cattle during summer.
Journal of Medical Entomology, 1981Cattle scabies, caused by Psoroptes ovis , became latent during the summer on 5 unstanchioned cattle in Kerrville, Texas, USA. There was a complete resolution of lesions, disappearance of pruritus, and apparent extinction of the mite population. However, the recovery that had begun in spring did not persist on 2 cattle after they were stanchioned and ...

Lipid ingestion from sheep epidermis by Psoroptes ovis (Acari: Psoroptidae)
Veterinary Parasitology, 1989Skin biopsies from three groups of sheep infested with Psoroptes ovis were cryofixed in liquid nitrogen to preserve outer epidermis with its lipid. From one group of five sheep (Group A), biopsies were taken from relatively healthy skin near the edge of scab lesions where mites had congregated.
