"現今以蚊子為媒介的疾病ㄧ直存在且有增加的趨勢，在熱帶以及亞熱帶地區登革熱以及瘧疾為非常嚴重的疾病。自1902 年到2007 年台灣都有登革熱感染的記錄，尤其在台灣南部的區域。連續使用經由化學合成之殺蟲劑例如: DDT、malathion(馬拉松)、 temephos(亞培松)以及其他試劑導致傳撥登革熱的病媒蚊產生抗藥性，且隨著使用次數的增加而抗藥性加劇。生物控制對於抑制蚊蟲是另一個眾所皆知的方法去取代化學試劑，已經成功的使用來消滅蚊蟲。ㄧ些生物控制的方法對於環境來說並不是一種自然的現象，例如蚊子魚(大肚魚)是一種外來種對原生種的傷害很大。我們需要探索一種不破壞環境生態的生物控制方法來抑制蚊子的大量滋生。在目前的計畫書中，將評估利用橈足類對於控制蚊子的幼蟲(孑孓)，以及行為學上的研究。在此研究中，對於控制蚊子的策略將會選擇在基隆周邊最有效掠(捕)食的原生種橈足類，且執行一些捕食效率的測試以及行為方面的實驗。這個實驗也包含了橈足類其附肢的捕捉能力。這個被建議的方法是一個對生態環境友善、安全、有效率且自我複製的技術，因此減少對化學合成殺蟲劑的過度依賴。至目前為止生物控制法之研究被使用在蚊子以及橈足類的交互作用上之文獻仍甚缺乏，因此這個研究將會對控制蚊蟲上非常有用且具有參考價值。" "The resurgence of mosquito-borne disease have been increased nowadays. Dengue and malaria are very serious diseases in the whole tropical and subtropical regions. Taiwan also has previous history of dengue epidemics since in 1902 to 2007. Major epidemics of dengue occurred in the Southern part of Taiwan. The continued usage of synthetic chemicals such as DDT, malathion, temephos and others led to the insecticide resistance to mosquito diseases vectors and these aggravate the problem by several folds. Alternative methods of mosquito control are much popular in place of the chemical control agents. Biological control is being used successfully for mosquito abatement. Some of the biological control agents of mosquito larvae are not natural to environment such as mosquitofish which is exotic species and very harmful for the native species. So we want to explore some eco-friendly method for mosquito bio-control. In the present project proposal, It is intended to assess the use of copepods for mosquito larval control and their behavioral study in the lab. In this study we will select the most useful predatory native copepod species around the Keelung and will perform some of the predation efficiency tests and behavioral experiments for the mosquito control strategy. And this study also includes the role of appendages in capturing ability of copepods. The proposed method is an eco-friendly, safe, cost effective and self replicative technique and thus decreases over-reliance on the synthetic insecticide. To the best of our knowledge, no study has been performed on mosquito-copepods interaction in Taiwan. So this study will be very useful and may be effective for the mosquito control"
