SUMMARYIn order to determine the way in which vertebrates infected with Crimean-Congo haemorrhagic fever (CCHF) virus and potential ixodid tick vectors interact in nature, immature and adult ticks of several species were fed on viraemic mammals and then assayed for virus content at varying times after feeding. CCHF virus was not isolated from ticks of six species tested after feeding as adults and immature forms on sheep with viraemia of 102·5−3·2LD 50/ml, nor from larval ticks fed on guinea-pigs and white-tailed rats with viraemia of 101·9−2·7LD 50/ml. In contrast, virus was isolated from 10 of 152 pools of engorged adult ticks of 5 species that fed on cattle with viraemia of 101·5−2·7LD 50/ml and from 3 of 137 female ticks after oviposition. Infection was transmitted to larval and nymphalHyalomma truncatumandH. marginatum rufipes, but not toRhipicephalus evertsi evertsi, from a scrub hare with viraemia of 104·250/ml but only nymphalH. truncatumandH. m. rufipesbecame infected from scrub hares with viraemia of 102·6−2·7LD 50/ml. Infection was transmitted trans-stadially inH. m. rufipesandH. truncatuminfected as nymphae, and adultH. m. rufipestransmitted infection to a sheep. No evidence of transovarial transmission was found in larval progeny of ticks exposed to CCHF virus as adults on sheep and cattle or as immatures on scrub hares.

The validity of the subgenus Hyalommina is discussed and reaffirmed.Hyalommina is differentiated from Hyalomma by the absence of the subanal plates in the males and by the humped tarsi and the more or less hexagonal basis capituli in both sexes.The male and the female of H. rhipicephaloides Neumann, 1901 are re-described. The larva and nymph of H. rhipicepholoides are described for the first time.The Indian species H. hussaini Sharif, 1928 and H. kumari Sharif, 1928 are re-described. H. hussaini var. brevipunctata Sharif, 1928 is considered as a species inquirenda.H. lewisi Schulze, 1936 is synonymized with Hyalomma truncatum K., 1844 (Feldman-Muhsam, 1954).

The distribution and monthly dynamics of bovine ixodids in Sokoto Township and environs were recorded between Jan 2009 and Dec 2010. Monthly tick collections were performed on 400 animals from which a total of 12, 296 ticks were collected. Ticks from each cattle were collected separately using a pair of blunt forceps, into labelled universal bottles containing 70% ethanol into which 5% glycerine was added to keep specimens better preserved. On each label, the location, breed of the animal, number of ticks and date of collection were recorded. In the laboratory, Ticks were placed into petri dishes, counted, examined and identified with the aid of a dissecting stereoscope based on morphological Characteristics and aided by the use of standard keys according to Hoogstraal (1956) and Walker et al. (2003). These include Hyalomma truncatum (15.5%), Hyalomma dromedarii (13.3%), Boophilus decolaratus (11.3%) Amblyomma variegatum (10.6%), Hy. impeltatum, (10.1%), Hy. rufipes (9.4%), Hy. impressum (7.4%), Boophilus annulatus (4.4%), B. geigyi (4.3%), Rhipicephalus sanguineus (4.1%) Amblyomma hebraeum (3.4%), Rh. evertsi (2.6%), A. pomposum (2.0%), Rh. lunulatus (1%) and Rh. senegalensis (0.5%). Hyalomma. truncatum, Hy. impeltatum, Hy. Impress B. annulatus, A. hebraeum, A. pomposum, Rh. lunulatus and Rh. senegalensis were recorded for the first time in the Study area. The distribution and dynamics of cattle ixodid ticks has not been hitherto chronicled in the study area.
