국문 초록

화학 살충제 는 산렴해충을 방제하는데 매우 효과적이지만， 다른 많은 절지동물 들에게도 심각한 피해를 초 래한 다. 살충제가 산림 절지동물들에게 미치는 효과를 파악하기 위해， 솔잎흑파리 를 방재하기 위해 a ldicarb와 phosphamidon 등 두 종류의 살충제 를 적용한 지역과 비닐 로 피복한 지역에서 곤충의 다양성을 조사하였다. 곤충의 종다양성 조사결과 살충제 및 비닐 로 피복한 지역에서 곤충의 종다양성은 정상적인 숲 에서보다 매우 감소하는 현상을 보였다. 따라서 절지동물들의 종 다양성에 적은 피해를 미치면서 해충을 방제할 수 있는 대안적인 방법을 개발하는 연구가 필요하다.

영문 초록

Application of pesticides is easy and effective methods for controlling harmful insect pests that damage forests . Chemical pesticides, however, may have serious impacts on many useful arthropods as well as target pests. To understand the impacts of pesticides, we investigate species diversity of insect communities in the forests where two pesticides of aldicarb and phosphamidon and vinyl-covering were treated to control pine gall midges (Thecodψ， losis japoneηsis). Species diversity was highest in a pesticide-untreated forest, whereas the diversity was much lower in two pesticide-treated forests and the forest with the ground surface covered with vinyl. The number of individuals collected also decreased in the pesticide-treated forests. Thus, aldicarb and phosphamidon have to be treated very restrictedly, or altemative pesticides need to be developed for controlling T japonensis. Monthly species diversity was highest in August. Thus, application of pesticides has to be escaped in August when the highest species diversity is expected. Since T japonensis was collected most abundantly in early May in the pesticide-untreated natural forest, the treatment of pesticides is recommended highly in May or right before the month.
