Abstract

Seasonal fluctuations in density of mosquito species were investigated at two cow sheds near to a large, reedy marsh with fairly polluted brackish water near the coast of Yongam-ri, Cheongryang-myon, Ulsan, Korea. Female mosquitoes were collected biweekly using Nozawa light traps from March to September, from 1999 to 2001. On average, 4,416.1, 5,505.9 and 6,863.8 females per trap night were collected from 10 species in 5 genera in 1999, 2000 and 2001, respectively. Among them, An. sinensis was most abundant (53.4% in species ratio), followed by Cx. tritaeniorhynchus (43.0%), Cx. inatomii (1.6%), Ochlerotatus dorsalis (1.3%) and Cx. pipiens pallens (0.5%). A malaria vector, An. sinensis and a Japanese encephalitis vector, Cx. tritaeniorhynchus were collected 3,663.3 females and 3,142.5 females per trap night from June to September for the years, respectively. According to the biweekly population changes at the area, Cx. inatomii which was dominant species in 1997, was the most abundant in the early July during 1999-2001.

울산시 울주군 청량면 인근 해안가 주변의 저습지를 보유한 용암리에 서식하는 모기의 계절적 발생소장을 조사하였다. 성충 채집은 Nozawa 유문등을 이용하여 3년(1999-2001) 동안 3월부터 9월까지 두 곳의 우사에서 격주에 한번씩 암컷을 대상으로 실시하였다. 채집된 암컷 성충은 1999년에 트랩당 평균 4,416.1마리, 2000년에 5,505.9마리, 그리고 2001년에 6,863.8마리였다. 채집된 모기의 종류는 5속 10종이었으며, 가장 높은 채집수를 보인 종은 중국얼룩날개모기로 종비는 53.4%였으며 다음으로 작은빨간집모기(43.0%), 이나도미집모기(1.6%), 등줄숲모기(1.3%), 빨간집모기(0.5%) 순이었다. 말라리아 매개모기인 중국얼룩날개모기와 일본뇌염 매개모기인 작은빨간집모기의 주요발생 시기인 6월부터 9월까지의 트랩당 평균 채집수는 각각 3,663.3마리와 3,142.5마리였다. 1997년 조사에서 우점종으로 나타난 이나도미집모기의 채집수는 연중 7월 초순에 가장 높게 나타났다.
