title: Studies on ticks of veterinary importance in Nigeria. XI. Observations on the biology of ticks detached from the red-flanked duiker (Cephamophys rufulatus) and parasites encountered in their blood.
abstract: Some aspects of the biology of Amblyomma variegatum and Boophilus decorolatus detached from red-flanked duikers were studied. Smears were also made from the blood of the duikers and examined for the presence of parasites. Anaplasma marginale was the only blood parasite found in the blood smears. Compared with ticks detached from cattle, duiker ticks produced a greater number of eggs. The lengths and breadths of eggs produced by duiker ticks were greater than those of cattle ticks and unlike A. variegatum detached from cattle, the lengths and breadths of eggs of earlier and later ovipositions of this species detached from duiker were similar. Whereas deformed eggs characterised by circular shape and small size constituted a small percentage of eggs of cattle ticks, none was found among eggs of duiker ticks. The pre oviposition, oviposition and eclosion periods, microscopic egg structure, embryonic development, hatching patterns and mortality rates of the eggs of ticks from both hosts were similar.
