Transcript of 病媒管制考前總複習

蒼蠅V.S.蚊子 Important species : 病媒 Anopheles 瘧蚊 Culex家蚊 Aedes斑蚊 Mansonia曼蚊 管制 Pest Management Anopheles 瘧蚊 :
malaria(瘧疾), filariasis (班氏、馬來絲蟲),arboviruses(蟲媒病毒) Culex 家蚊:
日本腦炎,filariasis班氏絲蟲, arboviruses(蟲媒病毒) Aedes 斑蚊:
yellow fever, dengue(登革熱), encephalitis virus(腦炎), filariasis(絲蟲症) Mansonia 曼蚊:
馬來絲蟲 蚊子唾液 成分與功能: 1.Anticoagulant(抗凝血素) :
避免宿主血液凝結,阻塞口器。

2.Antihaemostatic enzymes (抗血液恆定酵素):
出現血包。

3.Anaesthetic substances (麻醉物質):
使宿主降低疼痛感,減少宿主抵抗行為。 1.口器 3.翅膀後邊有細毛 2.頭胸腹翅脈有鱗片 Differences between mosquitoes and flies 1.Anthropophagic : 人類
2.Zoophagic :非人宿主(動物)
3.Ornithophagic : 鳥類 食性 叮咬人處 消化血液使卵朝巣成熟處 Endophagic : 室内 ex:瘧蚊
Exophagic : 室外 ex:斑蚊
Endophilic : 室内 ex:瘧蚊
Exophilic:室外 ex:斑蚊 Airport malaria ?
飛機場瘧疾,病媒蚊可藉由交通工具等媒介傳播。 Q&A 防治法 一、生物防治
1.天敵ex:大肚魚2.病原體與寄生蟲ex:蘇力桿菌3.基因控制ex:放射線照射 二、物理防治
1.填滿2.引流3.加蓋 三、化學防治
1.油脂ex:礦物油2.巴黎綠(毒性顆粒性物)3.殺蟲劑ex:DDT Q&A 1.常浮於水面的幼蟲-瘧蚊
2.可用除草劑防治的幼蟲-曼蚊
3.什麼是IGRS?分哪兩種?
昆蟲生長調節劑,
a.擬青春激素模擬物質
b.幾丁質合成抑制劑
4.什麼是ULV?
將殺蟲劑濃縮,增加噴灑效率。
5.空中噴灑的顆粒要大於地面噴灑 抗藥性的機制 1.增加行為逃避
2.減少作用位置敏感度
3.生理改變
4.生化解毒 指數 1.住宅指數:幼蟲孳生之百分比

2.容器指數:幼蟲孳生積水容器百分比

3.布氏指數:100個住家幼蟲孳生之積水容器數
