Abstract

Since Korea is home to Reticulitermes speratus, a kind of subterranean termites that prefer dark and humid conditions, there have been increasing damages to wooden structures by termites. One noticeable attribute of Korean subterranean termites is that they prefer than Pinus densiflora, the major construction material for Korean traditional houses. And because wide varieties of termites are distributed all over the world, it is not so easy to choose appropriate control methods depending on specific areas. This necessitates careful applications of the following control methods depending on the kinds of termites: fumigation treatment, soil termiticide, preservatives and insect treatment, termite colony elimination system, chemical treatment, and other physical and biological treatment methods. The purpose of this study is to investigate the control effects of environmentally-friendly Alkaline copper quaternary (ACQ), Copper Azole (CuAZ) and Micronized copper quarter (MCQ) on the termites contributing to the damage of wooden structures. It was found in this study that wood with preservative treatment produced a significantly higher termicidal efficacy than untreated wood.

우리나라에는 어둡고 습한 환경을 선호하는 지중흰개미의 일종인 일본흰개미(Reticulitermes speratus)가 전국적으로 분포하고 있으며, 점차적으로 목재 건축물에 대한 흰개미 피해가 증가하고 있다. 특히 일본흰개미는 국내 건축재로 많이 쓰이고 있는 소나무를 쉽게 가해한다. 전 세계적으로 다양한 종류의 흰개미가 분포하고는 있지만, 피해가 심해지는 만큼 적절한 방제방법을 선택하기는 어렵다. 무엇보다 분포하는 흰개미의 종류가 다양하기 때문에 훈증처리, 토양처리, 방부 방충처리, 군체제거시스템, 화학약품 처리, 물리 및 생물학적 처리 등의 방법을 이용하여 흰개미의 특성에 맞게 적용시켜야 한다. 본 연구는 현재 친환경 방부제로 사용되고 있는 구리계 방부제 Alkaline copper quaternary (ACQ), Copper Azole (CuAZ), Micronized copper quat (MCQ)가 흰개미로부터 목구조물의 피해를 방지할 수 있는지 그 효력을 조사하기 위하여 수행하였다. 그 결과 3종의 목재방부제로 처리된 방부목재가 무처리재보다 높은 방의 효과가 있는 것으로 나타났다. 또한, 각 방부제의 주입량에 따라 방의효력이 다르게 나타났다.
