Abstract
This study was conducted at Alkadaro Quarantine for Animals Export to
determine the ticks infesting cattle destined for export. Half body collection
of ticks was carried out three times a month from 20 cattle during June, July
and August 2012. The cattle for export had been brought from EL Obied,
Gadarif and Nyala.
The results indicated that these cattle were infested with ten species of
ixodid ticks; these were Amblyomma lepidum, A. variegatum, Hyalomma
impeltatum, H. truncatum, H. rufipes, H. dromedarii, H. anatolicum,
Rhipicephalus (Boophilus) annulatus, R. (Boophilus) decoloratus and R.
evertsi evertsi. The most abundant tick species was A. lepidum. Its number
was 893 ticks (68.85%) followed by A. variegatum 132 ticks (10.18%), H.
impeltatum 113 ticks (8.7%), H. truncatum 46 ticks (3.5%), H. dromedarii
40 ticks (3.08%), H. rufipes 36 ticks (2.8%), H. anatolicum 29 ticks (2.2%),
R. evertsi evertsi 6 ticks (0.5%), R. B. annulatus 1 tick (0.08%) and R. B.
decoloratus 1 tick (0.08%).

The mean tick species on cattle brought from EL Obied was (9±0.6), Gadarif
(7±0.5) and Nyala (5±0.5). Cattle older than four years carried the highest
tick load (10.5±0.7) followed by cattle 3- 4 years old (7.4±0.6) and cattle 2-
3 years old (6.3±0.4), whereas the calves younger than 1 year carried the
lowest tick load (4.1±0.6). Cows carried significantly more ticks (8.2±1)
than bulls (6.9±0.3). Butana type of cattle carried higher (7.6±0.5) tick load
than Kenana (6.7±0.4). Cattle with white coat colour carried the highest
mean load (7.3±0.4) while the lowest mean load was carried by brown coat
colour cattle (6.4±0.6). Seasonally, the highest mean load was recorded in
July (8±0.7), while the lowest load was recorded in August (6.5±0.5).
According to the body predilection sites, the highest mean load was
collected from the udder (9.4±1.9), while the lowest load was from the
scrotum (6.3±0.6).
This study was carried out during a limited time. The results may be
different if seasonal variations are taken into consideration. However, the current
results may reflect only the fact that ticks brought to Khartoum are numerous and
varied in their species and origins.
