Abstract

The distribution of ticks and severe fever with thrombocytopenia syndrome virus (SFTSV) pathogens were investigated by collecting ticks from March to November 2018 in four environments (grass fields, copses, mountain roads, and tombs) in Jeju. Three thousand and ninety ticks were collected using a tick trap, and 1,569 ticks were collected using the flagging method. Of the 4,659 ticks collected, Haemaphysalis longicornis and Haemaphysalis flava accounted for 4,440 ticks (95.2%) and 219 ticks (4.7%), respectively. Nine hundred and fifty, 883, 847, and 410 ticks were collected from grass fields, copses, mountain roads, and tombs, respectively, using tick traps, whereas 704, 472, 197, and 196 ticks were collected from copses, mountain roads, tombs, and grass fields, respectively, using the flagging method. The largest fraction of ticks (2,978) was collected from April to August, and most were collected in May and June. Adult ticks comprised 94 percent of the total ticks from June to August. SFTSV was not detected in the 4,440 H. longicornis ticks or the 219 H. flava ticks collected in this study.

제주지역의 4개 환경(초지, 잡목림, 산길, 무덤)에서 2018년 3월부터 11월까지 진드기 채집을 통하여 진드기의 분포 특성 및 SFTSV 병원체 보균 여부를 조사하였다. Tick trap을 이용해 채집된 3,095마리와 flagging을 이용하여 채집된 1,569마리를 채집하였다. 총 4,664마리의 채집된 진드기 중에서 Haemaphysalis longicornis가 4,440마리(95.2%)로 대부분을 차지하였고, H. flava는 224마리(4.8%)가 채집되었다. 환경적으로는 Tick trap은 초지(953마리), 잡목림(883마리), 산길(847마리), 무덤(411마리)가 채집되었고, flagging은 잡목림(704마리), 산길(472마리), 무덤(197마리), 초지(196마리)가 채집되었다. 발육단계별로는 유충은 5월부터 채집되어 10월에 140마리, 11월에 280마리가 채집되었다. 약충은 4월부터 8월에 집중적으로 채집(2,978마리)되었고, 5월과 6월에 가장 많이 채집되었다. 성충은 6월부터 8월까지 전체 성충 중 94%가 채집되었다. 채집된 H. longicornis 4,440마리와 H. flava 224마리에서 SFTSV는 확인되지 않았다.
