Abstract

In order to investigate the density of seasonal incidence of mosquitoes, a vector of infectious diseases in Jeju region, this study collected mosquitoes using a Black light trap (BL) and Biogents' Sentinel 2 Mosquito Trap (BG), dividing the region into cattle sheds, habitats for migratory birds, and the downtown area, twice a month for 9 months from March through November 2018. Then, this study conducted identification and classification and checked for the presence of Flavivirus using reverse transcription polymerase chain reaction (RT-PCR). As for the mosquito population, 1,847 mosquitoes (six genera, 12 species) were collected. The places where most mosquitoes were collected were copses near craft workshops in habitats for migratory birds and Jungang-dong in the Seogwipo downtown area. For the population, Culex pipiens pallens was the dominant species (76.9%), followed by Aedes albopictus (8.9%). Most of the population was collected in June, followed by August and October. This study conducted a RT-PCR test with 1,847 collected mosquitoes, which were divided into 50 pools if they had Flavivirus. All turned out to be negative. However, the results of the investigation show the presence of Culex tritaineniorhychus, Aedes albopictus, and Anopheles sinensis and can be used as a basis for the comprehensive prevention management of mosquitoes.

본 조사는 제주지역 감염병 매개체인 모기를 대상으로 계절적 발생밀도를 조사하기 위해 축사, 철새도래지, 도심으로 나누어 2018년 3월부터 11월까지 9개월간 월 2회 모기를 BL과 BG를 이용하여 모기를 채집한 후 분류 및 동정을 실시하고, RT-PCR을 이용하여 flavivirus의 보유여부를 확인하였다. 채집된 모기는 6속 12종으로 1,847마리가 채집되었다. 채집 장소 중에서 철새도래지에서는 공방주변 잡목림, 서귀포 도심에서는 중앙동에서 가장 많이 채집되었다. 가장 많은 개체수로는 빨간집모기(Culex pipiens pallens)가 76.9%로 우점종이었고, 그 다음으로 흰줄숲모기(Aedes albopictus)가 8.9%로 나타났다. 가장 많은 모기개체수가 채집된 시기는 6월, 8월, 10월 순으로 나타났다. 채집한 모기 1,847마리를 50 pools로 나누어 flavivirus의 보유 여부를 RT-PCR검사하였으나, 모두 음성으로 확인되었다. 그러나 조사결과 작은빨간집모기(Culex tritaeniorhychus), 흰줄숲모기(Aedes albopictus), 중국얼룩날개모기(Anopheles sinensis) 서식하는 것으로 확인 되어 향후 모기에 대한 종합적인 방제 관리기준으로 활용될 수 있다.
