Abstract: Objective To investigate the prevalence of on-host ticks collected from domestic and small wild animals in Suzhou, Jiangsu province, China, and to provide a basis for prevention and control of tick-borne diseases. Methods On-host ticks were collected from animals in seven cities/districts in Suzhou from April to November, 2018, using the host body examination method. The main body surface areas of domestic animals were checked, and the on-host ticks found were collected with forceps; rat trap cages were placed in the field to capture small wild animals, and the animals captured were then checked throughout the body surface for on-host ticks. Results A total of 2 686 on-host ticks were collected from the animals in Suzhou. Species identification indicated that the ticks were Haemaphysalis campanulata (49.55%), Ha. flava (37.49%), Rhipicephalus sanguineus (11.36%), and Ha. longicornis (1.60%). The tick infestation rates for domestic and wild animals were 23.47% and 52.38%, respectively. The tick infestation rates for sheep, dogs, and cats as domestic animals were 34.57%, 22.50%, and 5.00%, respectively; the tick infestation rates for yellow weasels and hedgehogs as wild animals were 100% and 90.00%, respectively. Conclusion There are four on-host tick species commonly present on the domestic and small wild animals in Suzhou, and the tick infestation rate for animals is high; therefore, it is necessary to prevent the risk of tick-borne diseases.
