And the plant uses it to repel insects like mosquitoes, ticks, and mites.

植物用它驱除蚊子、壁虱和螨虫等昆虫。

Nantucket Island, the sleepy and idyllic summer paradise has a tick problem.

塔基特岛是宁静宜人的避暑天堂，但却饱受壁虱的困扰。

Controlling vectors means controlling such things as mosquitos and ticks, which can carry malaria or dengue fever.

控制病源意味着控制蚊子和壁虱等能携带疟疾和登革热病毒的蚊虫。

This includes vector-borne illnesses—those transmitted by mosquitoes, flies, ticks and bugs—such as Neglected Tropical Diseases.

包括病媒传播的疾病，也是通过蚊子、苍蝇、壁虱和臭虫传播的疾病，比如被忽略的热带病。

The chain of transmission starts when a tick bites a white footed mouse carrying Lyme disease.

当壁虱叮咬携带莱姆病菌的白足鼠时，这条传染链开始了。

That will lead to less ticks infected which will lead to less human's infected.

这将使少的壁虱被感染，从而降低人类被感染的概率。

The tick gets infected and then usually moves on to bite a deer where it continues to feed and reproduce.

被感染的壁虱继续叮咬动物，通常是叮咬鹿，并在其身上繁衍。

Ticks are the main transmitters of Lyme disease, a bacterial infection that can cause fevers, fatigue and rashes.

壁虱是莱姆病的主要传播者，这种细菌引起的疾病可以导致发热、乏力和皮疹等症状。

And with few natural predators, deer populations have exploded increasing the spread of ticks and the odds that you're bitten by one.

而由于缺少天敌，鹿群数目剧增，而壁虱自然随之大量繁殖，人类被叮咬的概率更高。

In other words, if mice can't carry Lyme disease then they can't pass it on to the ticks who bite them.

换句话说，如果老鼠不携带莱姆病菌，那么它不可能传播到壁虱身上。

The ticks and the diseases that come with it, right now, are an acceptable risk to live here and visit here.

目前，壁虱和病菌是居民和游客们可以接受的威胁。

It's home to centuries of history, 12,000 people year around, 50,000 or more in the summertime and an untold number of mice and ticks who play a starring role in our next story.

该岛历史悠久，约有12000名常住居民，而夏季岛上人口可达5万人，岛上有数不清的老鼠和壁虱，这是我们下一个故事的主角。
