中文摘要 | 此篇報告探討在實驗室水芙蓉及布袋蓮等水生植物對白線斑蚊Aedesalbopictus雌蚊產卵及幼蚊之影響。水面上水芙蓉覆蓋面對白線斑蚊雌蚊產卵有顯著性影響。1/3及2/3水芙蓉複蓋面者,雌蚊產卵量最多,分別為984個及929個,顯著多於水芙蓉全面覆蓋者(492個)及清水者(441個)。幼蚊飼育環境對白線斑蚊雌蚊產卵有顯著性影饗。種植布袋蓮的塑膠桶內所收集到之平均卵數最多,為1652個,與浸有枯葉者所收集到之平均卵數(1566個)沒有顯著性差異,而與覆有水芙蓉(600個)或清水者(162個)所採集到之平均卵數有顯著性差異。幼蚊之飼育環境對幼蚊之存活率、發育時間及成蚊大小有顯著性差異,而對蛹之發育時間沒有顯著性差異。枯葉加食物及清水加食物對幼蚊存活機率最佳,分別為94%及88%,而枯葉次之(81%)。枯葉(不管加食物與否)所飼養之蚊蟲,其所需發育時間均較短且個體較大。清水加食物次之,而水芙蓉加食物及清水之個體大小相似,而後者所需時間更長。長期種植水芙蓉,會減少白線斑蚊產卵機會,且無法有效提供幼蚊發育所需食物。而長期種植布袋蓮雖不會減少白線斑蚊產卵機會,但孵化之一齡幼蚊無法存活。兩者皆可為防治白線斑蚊的可行辦法,然仍需進一步由野外長期實驗測試。 |
英文摘要 | Influence of aquatic plants on larval survival and development as well as adult oviposition and body size of Aedes albopictus (Skuse) were studied in the laboratory. Two common aquatic plants, water lettuce and water hyacinth were chosen. More number of eggs were found when 1/3(984 eggs) or 2/3 (929 eggs) of the water surface were covered by water lettuce, comparing with total coverage (492 eggs) and no coverage (441 eggs) treatments. Water tank with water hyacinth attracted females to lay the highest number (1652) of eggs, which was not significantly different from number of eggs (1566) from tank covered with dried leaves. Fewer number of eggs were found in water tank covered with water lettuce (600 eggs) or in water without any coverage (162 eggs). Aquatic environments significantly influenced the larval survival, development, and the size of adult, but not the duration of pupation. Larvae survived best in water with food (pig liver powder:yeast=1:1) with dried leaves (94% survived) or w/o dried leaves (88% survived). The larval survival in water with dried leaves w/o food was 81%. The larval developmental period in water with dried leaves (with or w/o food) was shortest and the largest adults were obtained. Water with food was the next. Adult body sizes were similar when reared in water with water lettuce and food or reared in water only, and development was slower in the latter treatment. Water lettuce eliminated the egg laying and larval survival of Ae. albopictus. Water hyacinth decreased larval survival. Both of the water plants have the potential to eliminate the occurrence of Ae. albopictus; however, further and long term field studies are necessary to assure the results. |
