초록
본 실험은 구리가 흰줄숲모기, Aedes albopictus의 발생에 미치는 생물학적 영향을 조사하기 위하여 수행하였다. 흰줄숲모기 3령, 4령 유충을 각각 다른 농도의 구리용액(0.0, 2.5, 25.0, 50.0 ppm)에서 24시간, 48시간 처리한 후 치사농도를 결정하고, 사육용액(tap water)으로 옮겨 사육하여, 유충의 용화율, 성충의 날개길이를 측정한결과는 다음과 같다. 50% 치사농도(LC50)는 4령 유충24시간 처리군에서 35.65 ppm으로 나타나 다른 처리군에 비해 가장 저항성을 지닌 것으로 나타났다(Table 1). 유충의 용화율은 고농도 48시간 처리군에서 낮게 나타났으며 특히 3령 유충 48시간 처리 군에서 14% (암컷9%, 수컷 5%)로 가장 낮았다. 또한 우화 후 성충의 날개길이는 처리 농도가 증가하고 긴 처리 시간이(48시간)감소하는 것으로 나타났다. 이러한 실험 결과들은 흰줄숲모기의 각 발생단계에 구리를 처리한 결과 처리 농도및 처리 시간에 따라 치사량, 용화율, 날개길이 등에 많은 변화를 나타내었는데 이는 중금속이 곤충의 유충발육과 변태에 영향을 끼치며, 이와 수반되는 물질대사에도 영향을 미치는 것으로 여겨진다.
Abstract
The mosquito, Aedes albopictus is important vector of humen phatogen such as dengue fever. And Aedes albopictus has widly distribution in oriental regions. This study was conducted to investigate the biological effects of cooper on the development of the Asian tiger mosquitoes, Aedes albopictus (Skuse). Aedes albopictus was affected with pupation ratios, mortalities, and wing lengths of the 3th and 4th instars by exposure to different concentration CuCl2 (0.0, 2.5, 25.0 and 50.0 ppm)for 24 h and 48 h depending on dose and exposure period. The lowest LC50 (median lethal concentration)value of CuCl2 was 18.1 ppm at the 3rd instars for 48 h exposure. The pupation ratio of the larvae exposed at 50.0 ppm for 48 h was 14% which was much lower than those exposed to other treatment groups Changes of adult wing length showed significant decreased by Cu treatment. In conclusion, the most prominent effects of high concentration and longer exposure period were to reduce in the survival and pupation rates of larvae and wing length of Ae. albopictus.
