Abstract 1. A total number of 1856, farm animals in Egypt were entomologically examined seasonally during the year 1987 for common skin parasites. 2. Out of 767 examined cattle, 285 (37.1\) were infested with Boophilus annulatus ticks, while out of 649 buffaloes, 36 (5.5\) were infested with the same ectoparasite, in addition 378 (58.2\) were parasitized by Psoroptes natalensis mites; as well as 522 (80.4\) were attacked by Haematopinus tuberculatus blood sucking lice and out of 440 sheep, 226 (51.3\) were infested with Psoroptes ~ mites. 3. Seasonal incidence of tick infestation has undergone variation, the highest incidence was observed during summer while the lowest one was noticed in winter. 4. Tick index and \ of infestation go hand by hand and the average tick load/cattle was more than in buffaloes. 5. The most preferable sites for infested ticks were in this arrangement, neck, dewlap, under the tail and thighs in both species of animals. 6. Seasonal incidence of mites infestation has undergone variation, higher incidence was observed during winter and lower one was in summer season in both buffaloes and sheep. 7. The predilection sites for mange mites were arranged as, withers, back, lumbar, croup and under the tail regions in buffaloes while in sheep were ears, nose, forehead and eye lids. 8. Lice infestation in buffaloes has undergone seasonal variation, highest incidence was observed during winter and lowest one was noticed in summer. 9. The predilection sites for lice were, neck, shoulders and chest in buffaloes. 10. The prevailing temperature as well as the hygienic conditions and to some extent relative humidity under which farm aniaals are kept, play an important role in incidence of skin parasites infestation. |
