A survey of mites on farm animals in Libya.

In 1985-1988, 2287 farm animals (cattle, camels, sheep, goats, horses, donkeys, dogs and rabbits) suspected of carrying parasitic mites were examined at 58 farms throughout Libya. Mites were identified on 1303 of these animals. The commonest parasites on cattle were Psoroptes and Chorioptes, on camels and sheep were Sarcoptes and Psoroptes, and on goats were Sarcoptes and Demodex. Infested horses carrier Psoroptes or Chorioptes, and one donkey carried Sarcoptes. Otodectes was common on dogs, but Sarcoptes was rare and no Demodex were seen. Rabbits often had psoroptic ear mange or sarcoptic body mange. Dermanyssus gallinae and Ornithonyssus bursa were seen on chickens, but no mites were found on pigeons, ducks or turkeys.

A survey of ticks on farm animals in Libya.

Thirteen species of ixodid ticks and two species of argasid ticks were collected during a three-year survey of 58 farms in Libya. These included Boophilus annulatus, B. microplus, B. decoloratus, seven species of Hyalomma, Rhipicephalus sanguineus, Rh. evertsi, Rh. bursa, Argas persicus and Ornithodoros foleyi. This is the first recording of B. microplus, B. decoloratus and Rh. bursa in Libya. Of 20,391 animals examined by random sampling, 2020 (9.6%) had ticks; particularly common were Hy. dromedarii on camels, Hy. impeltatum on sheep and Hy. excavatum on cattle. The tick found most frequently overall was Hy. dromedarii.
