Abstract:
Objective In this study, ecological monitoring data of ticks in Changzhou City(2021-2024)were analyzed to understand the composition, distribution, density, and seasonal trends of the different species and thereby provide a scientific basis for tick-borne disease control strategies. Methods Parasitic ticks were monitored via host surface examination, whereas questing ticks were monitored using the flagging method. Results In total,1 506 ticks(636 parasitic,870 questing), belonging to 1 family,2 genera, and 5 species, were collected. Haemaphysalis longicornis(1 389)was the dominant species, followed by Hae. flava(111), Hae. phasiana(3), Amblyomma testudinarium(2), and Hae. hystricis(1). The parasitic tick index was 1.89 (goats as the dominant hosts), whereas the questing tick density was 0.65 individuals/(cloth flag·100 m) (forest parks as the dominant habitat). Tick activity peaked in July. Conclusions Hae. longicornis is the dominant species in Changzhou City, with activity peaking in July. As these ticks pose a significant public health risk, targeted control measures are recommended.
