Abstract

This study was conducted to elucidate the seasonal prevalence of adult mosquitoes and occurrence of anopheline larvae in Gimpo, Gyeonggi province, Republic of Korea. Sampling of adult mosquitoes was carried out 18 times from May to September in 2008, using light traps at six sites. A total of 48,919 individuals belonging to 16 species and 8 genera were collected. Aedes vexans nipponii (43%) was the most frequently collected, followed by Anopheles sinensis (34%) and Culex tritaeniorhynchus (14%). The seasonal prevalence of anopheline mosquitoes had a different occurrence compared to that of Cx. tritaeniorhynchus. Anopheline larvae were collected using a standard dipper (size = of 350 ml) at eight habitat types of 203 point locations. Anopheline larvae were confirmed from 138 points (63%). The average larval population per dipper was highest in the lotus plantation (6.9 individuals), followed by irrigation channel (4.5 ind.), dropwort field (3.4 ind.), fallow field (3.1 ind.), paddy field (1.8 ind.), swamp (1.4 ind.), and stream (0.2 ind.). There was no significant relationship observed between larval density and DO, pH, salinity, or distance from blood meal hosts (cowshed, pigsty, chicken-house). In the results of average nearest neighbor analysis (ANNA), the distribution of whole points for mosquito larval collection was clustered, and points with over 4.0 larvae per dipper were randomly distributed. Within the study area Haseong-myeon, those points where over 3.0 larvae were collected were of a dispersed distribution.

본 연구는 김포시에서 모기성충의 계절적 발생소장과 얼룩날개모기류 유충의 발생을 파악하기 위해서 실시되었다. 성충모기는 6지점에서 유문등을 이용하여, 2008년 5월부터 9월까지 조사되었다. 조사결과 8속 16종 48,919마리가 채집되었다. 금빛숲모기(Aedes vexans nipponii)가 43%로 가장 많았고, 중국얼룩날개모기(Anophels sinensis)가 34%, 작은빨간집모기(Culex tritaeniorhynchus)가 14%로 이 3 우점종이 전체의 91%를 차지했다. 얼룩날개모기류의 계절적 발생소장은 작은빨간집모기와 비교하여 다른 피크를 보였다. 얼룩날개모기류 유충은 203지점 중 138지점(63%)에서 확인되었다. 지점당 정량조사 결과에서 평균유충밀도는 연꽃 재배지가 6.9개체로 가장 높았으며, 다음으로 수로가 4.5개체, 미나리꽝이 3.4개체, 유수지가 3.2개체, 휴경논이 3.1개체, 논이 1.8개체, 습지가 1.4개체, 하천이 0.2개체 순이었다. 유충밀도와 용존산소량, 산도, 염분도, 흡밀원(축사, 돈사, 계사) 사이에 유의한 관계성은 없었다. 최근린평균거리분석(ANNA)의 결과에서, 유충 조사지점간 분포패턴은 전체 조사지점간과 4.0개체 이상 확인된 지점간에서 각각 밀집분포와 불규칙분포였다. 하성면에서는 유충이 3.0 개체 이상 확인된 지점간 분산분포를 나타냈다.
