흰줄숲모기는 뎅기열과 치쿤군야 바이러스를 매개하며, 최근에는 지카바이러스를 매하는 것으로 알려지면서 많은 관심을 불러일으키고 있다. 흰줄숲모기의 월별 발생밀도, 흡혈원 그리고 뎅기바이러스 감염여부를 확인하기 위해 인구밀도가 높은 서울 도심 공원을 조사지역으로 선정하였다. 모기의 채집은 BG sentinel 트랩과 backpack aspirator룰 이용하여 5월부터 10까지 월 2회 실시하였다. 채집 모기 중 흰줄숲모기는 전수 흡혈원 조사와 뎅기바이러스 감염 검사를 실시하였으며, 나머지 모기종에서는 흡혈모기만을 대상으로 흡혈원을 확인하였다. 채집결과 총 7속 12종 54,685마리의 모기가 채집되었으며, 흰줄숲모기의 월별 분포는 6월부터 증가하기 시작하여 8-9월에 최고의 피크를 이룬 후 10월부터 급속히 감소하는 경향을 보였다. 흰줄숲모기의 흡혈원으로 71%가 포유류로 나타났으며, 그 뒤를 이어 조류 26%, 양서류 2%, 어류 1%로 확인되었다. 뎅기바이러스 감염확인 결과에서는 1,995마리(79 pool)에서 모두 음성으로 나타났다.
Understanding the metapopulation structure and movement of a species are required for conserving the species. In this paper, migration patterns and connectivity of patches of a threatened butterfly, Pamassius bremeri Bremer, were postulated using the mark-release-recapture (MRR) technique in a habitat located in the mid-southern region of the Korean peninsula. A total of 194 individuals were captured (137 males and 57 females) and, of them, 93 individuals (73 males and 20 females) were recaptured during the MRR experiment. The migration analysis showed 23-150% immigration and 28-53% emigration. There were high correlations between the migrating individuals and the distance between patches, but there was no correlation between migrating individuals and patch size or between migrating individuals and the number of host plants. Consequently, the migration of butterflies occurred frequently between closer patches, while patch size and quantity of the food plant had minor effects on migration behavior. Additionally, males migrated more frequently than females. Analysis of the migration patterns of P. bremeri showed that the central patch played an important role on linking patch groups and more frequent migrations were monitored between nearby patches than between the remote patches. This study suggested that active migrations take place between the neighboring multiple patches and these are accelerated if there is a stepping-stone patch between them.
