Abstract

To study the interaction between rice weevil and storage molds, the preference of rice weevil to the four mold species (Aspergilus candidus, A. niger, A. flavus and Penicillium spp.) and the resulting reproduction of the rice weevil were observed. The rice weevil preferred rice grains contaminated with the molds to autoclaved ones regardless of the mold species tested. Among the four mold species, A. candidus and Penicillium sp. were highly preferred than the others. Reproduction of the rice weevil was higher on the grains contalminated with A. candidus and Penicillium sp., than on autoclaved ones, but was lower on the grains contaminated with A. flavus. The partial disagreement between preference and reproduction of the rice weevil might be a suggestion that both the weevil behavior adapting nutritional requirements and the process of the long intensive coadaptation of the rice weevil and storage molds requiring similar moisture niche are the major components of the population interaction between the weevil and molds.

쌀바구미와 저장 곡물 곰팡이간의 상호작용 분석의 일환으로 곰팡이 종에 대한 쌀바구미의 분포 선호성을 조사하였다. 쌀바구미는 비교 대상 4종 곰팡이(Aspergillus candidus, A. niger, A. flavus와 Penicillium spp.)에 오염된 현미를 살균된 현미보다 선호하였으며, 선호도는 A. candidus와 Penicillium spp.에 대해서 가장 높았다. 차대 쌀바구미 우화수는 A. candidus와 Penicillium 오염미에서 가장 많았으며 A. flavus 오염미에서 가장 적었다. 쌀바구미의 곰팡이 오염미에 대한 선호와 쌀바구미 적합도간 불일치 현상은 쌀바구미의 분포 및 곡물 곰팡이 선호도가 알려진바 유사 니체에서의 장기적인 공진화 과정을 거쳐 이루어진 종간 상호작용의 조정과 아울러 영양적 특성 등 단기적 서식환경의 적절성의 두 가지 측면에서 설명될 수 있음을 암시하는 것으로 생각된다.
