Abstract

지리적 환경적으로 다른 두 지역에서 채집한 무당벌레(Harmonia axyridis)의 월동개체군에 있어, 평균기온이 높고 일조시간이 상대적으로 긴 지역에서 멜라닌 계통의 색상패턴이 발현율이 다소 높게 나타나는 것을 확인하였으며, 같은 지역에서 계절적 차이에 따른 무당벌레의 색상패턴별 발생양상 또한 유충시기를 평균기온과 일조시간이 긴 시기에 노출되었던 개체군에서 멜라닌 계통의 색상패턴 발현율이 높게 나타나, 온도나 일조량과 같은 환경조건이 무당벌레의 색상패턴형성에 있어 영향을 미칠 수 있음을 확인하였다. There was different between two differential geographical and environmental condition areas on elytra color expression patterns of the multicolored Asian lady beetles (Harmonia axyridis). Especially, it was investigated that expression rates of melanic patterns (conspicua, spectabilis and axyridis) relatively increased in overwintering populations collected in highly mean temperature and longer cumulative daylength area. In addition, in the same collection site, the seasonal difference had influenced on color patterns of H. axyridis. Although these effects didn't were not observed in the laboratory, environmental conditions such as temperature or cumulative daylength might be factors that gave an effect on color pattern formation.
