When inspecting the effects of Greater Kaohsiung’s plan to use seawater to exterminate mosquitoes at 9am on the morning of Nov. 11, it was found that in 10 bags containing a total of 200 Aedes aegypti mosquito larvae, all larvae in eight of the bags had died. In each of the remaining two bags, one and two larvae had survived, respectively. According to the Department of Health’s preliminary evaluation, the effects were quite good, and during the afternoon of the same day, they were going to inspect the survival rate after 24 hours.

According to the department, it takes about four days for larvae to transform into a mosquito, and the plan for the program was therefore to continue observations for four days. If all the larvae were to die within four days, the department would quickly expand the experiment and it had preliminarily selected 400m of a ditch along an epidemic hotspot in part of the Sanmin District to be filled with seawater.

高市海水滅蚊計畫十一月十一日上午九點檢視成果,十袋共兩百隻斑蚊的「孓孑」裡,有八袋全數被海水鹹死,另兩袋各存活兩隻、一隻,衛生局初步評估成效不差,下午將繼續觀察二十四小時存活情況。

衛生局說明,孓孑羽化成蚊時間約四天,海水滅蚊計畫據此設計最長觀察日為四天,若四天內孓孑全部陣亡,將積極規劃擴大實驗範圍,初步會選定三民區部分疫情熱區周遭四百公尺水溝灌注海水。
