A review of Melophagus ovinus (L.), the sheep ked.
The sheep ked Melophagus ovinus is a member of the parasitic Dipteran family Hippoboscidae; it was a widespread ectoparasite of sheep that was of veterinary importance until the introduction of effective pesticides. Since then it has become of less concern and may have become a relatively uncommon species through much of its former range. Changes in agricultural practice, both greater intensification and development of more extensive systems (including organic farming and conservation grazing), may allow resurgence and a review of existing knowledge of M. ovinus may be timely. This paper reviews the biology, annual population cycles, natural causes of mortality, veterinary and economic significance and control of, and host resistance to, M. ovinus.
