Objective To investigate the infestation of parasitic ticks in goats in Yiwu, Zhejiang province,China,and to provide a basis for the prevention and control of ticks and tick-borne diseases. Methods A herd of free range goat in Yiwu was selected, and the parasitic ticks on the body surface of goats were monitored in the last ten days of each month from March to November 2020. The species of collected ticks were identified and the number was recorded;the parasitism of ticks in goats was analyzed. Results A total of 90 grazing goats were monitored from March to November 2020,among which 68 (75.56%) were positive for ticks. A total of 311 ticks were captured, with a tick index of 3.46; There were 4 species of ticks, the dominant tick species was Rhipicephalus haemaphysaloides, accounting for 45.02% (n=140) of the total,followed by Haemaphysalis longicornis,accounting for 30.23% (n=94). Tick index was relatively high from March to May and in October. Larval, nymphal, and adult ticks were caught all year round. Five goats (5.56%) were concurrently infected with 3 species of ticks,and 14 goats (15.56%) were concurrently infected with 2 species of ticks. Conclusion The positive rate of ticks in goats is relatively high in Yiwu. Ticks are active all year round,with the peaks in March-May and October. Enough attention should be paid to this.
