摘要

1989年3月在屏東縣琉球鄉2 , 480戶問春調查中，統計全鄉約有5,533個儲水容器，其中 49.83％容器供儲水飲用，50.17%容器供盥洗衣物及澆水種積使用，另有32.42％民眾願意配合在往家儲水容器中養魚，以防治登革熱病媒蚊一一埃及斑蚊（Aedes aegypti）與白線斑蚊（Aedes albopictus)。4~10月間總計有17,600條之食蚊魚（Gambusia afffinis）、孔雀魚(Poecilia reticulata）、吳郭魚（Tilapia mossambica）、尼羅魚（Sarotherodon niloticus）被釋放至琉球鄉家戶儲水容器內，以防治登革熱病媒坎。比較釋放魚苗一個月彼之斑坎幼蟲家器指數變化，發現有魚容器之陽性容器指數為3.58，而無魚客器之陽性客器指數為25.97；另外比較5月份與9月份之斑炊幼蟲容器指數，發塊無魚容器之陽性容器指數由97.32際至18.00，顯示奏魚防治斑炊，初步效果顯著。在室內食坎魚取食量試臉中，食坎魚每條平均每天可取食31.33隻斑蚊幼蟲/0.4078克重魚，而在琉球鄉家戶儲水糟中，部份食蚊魚及孔雀魚可存活五個月以上，顯示應用魚類生物防治未來在琉球鄉登革熱病媒坎綜合防治過程中潛力無窮。

An investigation made in May 1989 with questionnaires to 2,480 families in Liouchyou Prefecture, Pingtung County, showed that there were about 6,533 water containers in the whole village, of which 49.83% were used to store water for drinking, and the remaining 50.17% were used for washing clothes and watering plants. 32.42% of the residents volunteered to rear fish in the family water containers to control the mosquito population.
During the period from April to October 1989, there was a total approximately 17,600 Gambusia affinis, Poecilia reticulata, Tilapia mossambica, and Sarotherodon niloticus released into the household water containers in the Liouchyou areas to control dengue vectors-Aedes aegypti and Aedesalbopictus. One month after the release, a comparison of the container index of Aedes larvae showed that among 530 containers with fish in them, the positive container index was 3.58; among the 3,219 containers without fish in them, it was 25.97. Furthermore, the positive container index without fish was as high as 97.32 in May 1989, and dropped to as low as 18.00 at the end of September 1989. This indicats that rearing fish to control household mosquitoes yielded significant results in the initial stage. Also, in some water containers Gambusia affinis and Porcilia reticulata lived longer than five months, and Gambusia affiniscould eat 31.33 Aedes larvae/0.4078g fish per day on the average. It appears that the biological control of dengue vectors by fish in the Liouchyou areas would be advantageous.
