Abstract

The seasonal pattern of larvae, nymph and adult life stages for three tick species were studied for April-October, 2014. Haemaphysalis longicornis (610), Haemaphysalis flava (296) and Ixodes nipponensis (15) were collected from Pocheon by the dragging and flagging method. H.longicornis (254), H.flava (345) and I.nipponensis (15) were collected from Cheolwon in the same way. H.longicornis adults peaked in June while nymphs were more frequently collected from April through June. In contrast, H.longicornis larvae were collected only in September and October. H.flava adults were collected in April, September, and October while nymphs were collected from April through October. The nymphs peaked in April in Pocheon while May was the peak in Cheolwon. Larvae of H.longicornis and H.flava were collected only in September and October. I.nipponensis adults and nymphs were more frequently collected in April, while the larvae were not collected during that period. Collecting ticks by the dragging and flagging method provides estimates of population densities for life stages of the selected species and the associated disease risk. These results can be used to predict seasonal population densities of ticks and the prevalence of tick-borne pathogens.

참진드기 3종류의 발육단계별 즉 유충, 자충, 성충에 대한 계절적 발생 유형을 2014년 4월에서 10월까지 조사하였다. 천끌기와 천젓기 방법으로 포천 영중면 금주리에서 작은소피참진드기 610개체, 개피참진드기 296개체 그리고 일본참진드기 15개체가 채집되었으며 같은 방법으로 철원 서면 자등리에서는 작은소피참진드기 254개체, 개피참진드기 345개체, 일본참진드기 15개체가 채집되었다. 작은소피참진드기의 성충은 6월에 가장 높은 채집 비율을 보였으며 자충은 4월에서 6월사이에 주로 채집되었다. 반대로 작은소피참진드기의 유충은 9월과 10월에만 채집되었다. 개피참진드기의 성충은 4월, 9월, 10월에 채집된 반면 자충은 4월부터 10월까지 채집되었다. 개피참진드기의 자충은 포천에서는 4월에 그리고 철원에서는 5월에 가장 많이 채집되었다. 개피참진드기의 유충은 작은소피참진드기의 유충과 같이 9월과 10월에만 채집되었다. 일본 참진드기의 성충과 자충은 주로 4월에 채집되었으나 유충은 채집되지 않았다. 천끌기과 천젓기 방법으로 채집된 특정한 진드기종의 발육단계별 밀도를 조사한 결과는 진드기의 계절별 밀도 평가와 진드기 매개 질병 위험 분석에 활용할 수 있다.
