Abstract:
We report a case of a tick bite by Haemaphysalis longicornis Neumann. The tick was found on the left knee of a 75-year-old male and captured alive. We observed its process of laying eggs and becoming larvae after human blood sucking. Our data include the size and weight of the female tick (8.2 X 6.2mm, 138mg) after blood sucking, preoviposition period(4 day), oviposition period(21 day), number of eggs(1486) and size of unfed larva(0.40-0.44 x 0.58-0.60 mm). It had a 2n number of 22 chromosomes which showed chromosomal pattern of bisexual clones but its life cycle, especially oviposition to hatching period, showed that of pathenogenetic clones. This is the first Korean report of a tick bite by Haemaphysalis longicornis Neumann and the laboratory observation of the causative tick laying eggs and becoming larvae.
