| the epidermal location and possible feeding site of psorergates ovis, the sheep itch mite. | skin biopsies from two merino sheep heavily infested with psorergates ovis were immersed in liquid nitrogen and cut into vertical frozen sections stained with lipophilic sudan iv or oil red o and haematoxylin. a survey of the lateral distribution of mite sections showed a majority (ca 80%) were in or within 0.2 mm of the follicle mouth. a survey of vertical distribution showed no mite penetration deeper than inner stratum corneum where 57% of mite sections were seen; 30% were within outer stratu ... | 1990 | 2344339 |
| the prevalence of itchmite, psorergates ovis, among sheep flocks with a history of fleece derangement. | an investigation of sheep flocks in the main sheep raising areas of new south wales showed that the itchmite psorergates ovis was frequently associated with fleece derangement. in 26 of the 41 flocks examined, p. ovis was the only ectoparasite detected. p. ovis and the sheep body louse damalinia ovis, were found in 5 flocks. no external parasites were found on sheep examined from the 10 remaining flocks. the type of fleece derangement most frequently recorded was rubbing which in some cases was ... | 1990 | 2375718 |

| prevalence of the causes of fleece derangement among sheep flocks in new south wales. | an investigation of sheep flocks with unknown histories of fleece derangement, selected at random from the main sheep raising areas of new south wales, showed that psorergates ovis was present in 53 of the 177 flocks surveyed and in 162 of the 3495 sheep examined. of the single causes of fleece derangement, the most prevalent was grass seed contamination (15.7%) followed by infestation with sheep body lice, bovicola ovis, (14.7%) and infestation with itch mite (7.8%). the prevalence of fleece de ... | 1993 | 8216084 |
| the effect of host nutrition on itch mite, psorergates ovis, populations and fleece derangement in sheep. | a group of thirty-two merino sheep infested with itch mites (psorergates ovis) and fed a maintenance diet which imposed moderate nutritional stress had a significantly higher mite population, significantly more skin scurf, and significantly more fleece damage or derangement (p < 0.05) than a second group of thirty-two infested sheep fed a diet designed for unrestricted body weight gain and wool growth. histologically there were no significant differences between the groups in the numbers of mast ... | 1996 | 8744703 |
