驱避剂为什么会对蚊虫有驱避作用?要了解这个问题,首先必须了解雌蚊是如何停落在温血动物身上吸血的,然后再进一步观察在驱避剂存在的情况下所发生的变化。一般认为,蚊虫“喜欢”由宿主发出的某种气味,而“厌恶”驱避剂的气味,其实,这种看法是不正确的。根据实验观察,蚊笼中的雌蚊,在无干扰的情况下,除了一些偶然的飞动之外,大都是停息在笼壁上。Daykin为了探索蚊虫偶然飞动的秘密,他放了100余只蚊虫在笼中,等它们都停息之后,记录在一定时间内蚊虫再飞动的数目。
Why is repellent repellent to mosquitoes? To understand this problem, it is important to know how the female mosquito stops smoking on warm-blooded animals before further observation of the changes that occur in the presence of repellent . It is generally believed that mosquitoes “like” some smell emitted by the host, and “disgust” the smell of repellent, in fact, this view is not correct. According to experimental observation, the mosquito in the mosquito cage, in the case of non-interference, except for some accidental fly, mostly resting on the cage wall. Daykin in order to explore the secret of accidental flying mosquitoes, he put more than 100 mosquitoes in the cage, wait for them all to rest, record the number of mosquitoes and then fly in a certain period of time.
