Abstract

Mosquitos serve as vectors for diseases, causing inconvenience as well as a threat to human life and health. Concern about mosquitos introducing and spreading new diseases has been intensifying. We observed a variety of mosquito habitats based on land cover classification from Korea's Ministry of Environment, and the mosquito species that could appear were classified according to the each habitat type. Finally, we suggested the best control methods for each type of habitat considering habitat characteristics and the ecological traits of mosquitos. Urban areas harbor various habitats for pests, contributing significantly to mosquito habitats. Control must be performed regarding larva and adults because various sources for habitats exist. Public mosquito control programs such as educational training, as well as information brochures can be effective in managing mosquito populations and public health. Agricultural areas show high densities of mosquito larva to lentic zones such as reservoirs, wetlands, paddy fields. So, biological control using natural predators may be effective in controlling mosquito populations. Forests are major habitats for Aedes albopctus, so physical controls should be deployed for residents living nearby, and excessive deforestation should be minimized. Other areas including aquatic ecosystems should be adopted regarding biological control using Bti (Bacillus thuringiensis var. israelensis) and chemical control for eradicating mosquitos. We classified habitats into four types of land cover patterns considering ecological traits and habitat preference, and suggest adequate control methods for each habitat type. Our suggestion can be used to positively contribute toward effective managing mosquito's density and reducing the damage to public health.

모기는 감염병을 매개하는 생물종으로서 인간생활에 불편을 야기하며, 교통 및 운송수단 등의 발달로 인해 새로운 질병 도입 및 질병 매개체의 확산에 대한 우려가 증가하고 있는 실정이다. 환경부 토지피복지도 분류체계와 연계하여 모기가 발생 가능한 서식지 유형을 파악하고, 각각의 서식지 유형 특성에 따라 출현 가능한 모기 종류를 함께 구분하였다. 또한 모기의 생태적 특성을 고려하여, 서식지 유형별로 최적의 방제 방법을 제시하였다. 도심지역은 위생 해충의 발생원이 다양한 서식지가 분포하는 지역으로, 최소 환경 조건만 갖춰진다면 모기가 대량 발생하기 적합한 환경일 것으로 보인다. 발생원이 광범위하기 때문에 유충과 성충 방제를 같이 수행하며, 시민들을 대상으로 방제 교육이나 홍보물을 배부하여 적극적인 방제의식을 함양시키는 것이 효과적일 것으로 판단된다. 농업지역의 경우, 저수지나 늪지, 논 등의 정수역에서 모기 유충의 서식밀도가 높을 것으로 예상되어 천적생물을 이용한 생물학적 방제를 이용하면 개체수를 조절하는 데 유용할 것으로 보인다. 산림지역은 흰줄숲모기(Aedes albopictus)의 주요 서식지로서 무분별한 산림벌채를 최소화하고 인근 거주민을 대상으로 물리적 방제를 실시해야 할 것으로 판단되며, 기타지역은 수생태계를 중심으로 발생 가능한 모기 유충을 방제하기 위해 생물학적 방제와 Bti를 이용한 화학적 방제가 병행되어야 할 것으로 보인다. 본 연구는 서식지를 크게 4가지(도심지역, 농업지역, 산림지역, 기타지역)로 분류하여 모기에게 적합한 서식지를 고찰하였으며, 모기 서식지별로 적합한 방제법을 제시하였다. 모기의 개체수를 보다 효율적으로 조절하고, 하절기 시민들의 불편과 피해를 감소시킬 수 있는 기초자료로 제공할 수 있을 것으로 전망한다.
