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.
