Abstract

Over a number of years studies have been carried out in Egypt on the transport by migrating birds of ticks that may transmit pathogens of man and animals. In continuation of these investigations 11 036 birds migrating southwards through Egypt were examined for ticks during the fall of 1962. The 881 infested birds (comprising 24 species and sub-species represented by 10 612 individuals) yielded 1442 ticks. Tick-host relationships were similar to those of previous years except that in 1962 the prevalence of infestation was almost invariably much higher than the averages for 1959-61. Five species of birds were added to the previous list of 40 infested forms. Previously unrecorded tick species taken during 1962 wereIxodes redikorzevi (a species from Asia very occasionally found in rodent burrows in Egypt), the rareHaemaphysalis inermis, andHyalomma a. anatolicum, H. anatolicum excavatum andH. dromedarii, which may have been carried from Asia or have attached themselves to the birds at the time of netting.

During the spring of 1962, altogether 1774 birds migrating northwards through Egypt were also examined. The 56 tick-infested birds (comprising 13 species represented by 867 individuals) yielded 186 ticks. As in previous years,Hyalomma marginatum rufipes was the chief species (89.25%) parasitizing spring migrants. A single specimen ofAmblyomma variegatum was taken onAnthus cervinus and 19 specimens of Ixodes?sp. nov. were collected fromSylvia c. communis and Motacilla a. alba.
