The earliest ticks were collected between 1906 and 1912: Hyalomma
anatolicum from Aden in 1906; Amblyomma variegatum and Aponomma
exornatum from Nigeria in 1907; Dermacentor rhinocerotis from
'Nyasaland ' in 1909; Amblyomma variegatum from Sierra Leone in
1913; Ixodes ricinus and Ixodes caledonicus from Scotland in 1910
and 1911 respectively; Ixodes uriae from the Shetland Islands and
Ixodes hexagonus from Wales in 1912. Ashworth collaborated with
Nuttall in describing Ixodes caledonicus in 1910.
Collecting continued throughout the 1920s to the 1950s and then
acclerated enormously when Dr J. Alan Campbell was appointed as
Lecturer in Parasitology in 1963. The bulk of the Collection was
amasssed from 1963 until 1980 when Alan Campbell died prematurely.
During this time, ticks appeared to have poured in from all over the
globe and from all kinds of domestic and wild animals - reptiles,
birds, marsupials, mammals, including the odd human, grass, sand and
human habitations. Alan Campbell and his post-graduate students were
the major collectors with contributions from eminent
entomologists - A.E. Cameron, D.S. Kettle, D.S. Saunders, R. Sutherst,
G.Theiler. Several University of Edinburgh expeditions to different
parts of the world made major contributions of ticks from wild animals.
A large, specialised collection of ticks from wild animals in Ghana
was collected by Dr Y. Ntiamoa-Baidu of the Ghanian Wildlife
Department as part of her study on the ticks of the grass-cutter,
Thyronomys swinderianus, in the 1970s.
