max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; line-height: 2em; text-indent: 2em; overflow-wrap: break-word !important;">在这众多诱惑中，最重要的当数二氧化碳，这是蚊子找到你的主要线索。值得注意的是，吸引蚊子的不是单纯的二氧化碳，而是二氧化碳的气流，通过辨别气流方向，蚊子才能锁定目标。在野外实验中，添加了二氧化碳的捕蚊器可以比没有添加二氧化碳的同类捕蚊器多捕捉8-45倍的蚊子。而给人戴上一个装有碱石灰（以中和呼出的二氧化碳）的面罩，可以让他被蚊子叮咬的几率大幅下降。虽然不同种类的蚊子之间略有差异，但基本上靠着二氧化碳，它们就能找到你，如果再配合上其他主要身体气味物质，如乳酸、丙酮和辛烯醇，寻找起目标来会更加容易。值得一提的是，有研究指出，众多驱蚊产品所含的避蚊胺（DEET）成分起作用的原理就是通过抑制蚊子感受这些线索的感受器，让蚊子找不着北。</p><p style="margin-top: 0px;

box-sizing: border-box; clear: both; min-height: 1em; line-height: 2em; text-indent: 2em; overflow-wrap: break-word !important;">所以一个刚运动完大汗淋漓的人就是蚊子的最爱，大口喘气呼出的二氧化碳和汗水中的化学物质都对它们有强烈的吸引力。一些二氧化碳排出量比较多的人，比如新陈代谢较普通人快的孕妇等，也可能比其他人更易被叮咬。</p><p style="margin-top: 0px; margin-bottom: 0px; padding: 0px; outline: 0px; max-width: 100%; box-sizing: border-box; clear: both; min-height: 1em; line-height: 2em; text-indent: 2em; overflow-wrap: break-word !important;"><br style="margin: 0px;

box-sizing: border-box; clear: both; min-height: 1em; line-height: 2em; text-indent: 2em; overflow-wrap: break-word !important;">另外，有人经常提到深色衣服易招蚊子，也是有道理的。当蚊子找到并飞近目标后，视觉就开始起作用，甚至对蚊子最终会不会落在这个目标身上有很大影响。蚊子的视觉系统在阴暗的环境中最活跃，太充足的光线或者完全黑暗都非它所爱，所以反光效果较弱的黑色最吸引它们。因为这种视觉偏好，在白天，蚊子喜欢黑色的温暖且潮湿的物体，比如你身上略带汗水的黑色T恤。所以想躲避蚊子的话，下次出门要避免这类着装喔！</p><p style="margin-top: 0px;

box-sizing: border-box; line-height: 2em; text-indent: 2em; overflow-wrap: break-word !important;">但对于这样的结果，Shirai自己也认为，即使是血型抗原实验也无法作为蚊子对血型存在偏爱的实证，因为实际情况中抗原在人体表面分布的浓度低到蚊子侦测不到的程度。综合来看，Shirai认为自己的研究并不能证明血型与吸引蚊子的程度有关。对Wood实验结果与自己实验结果的差异，Shirai推测，可能的解释是蚊子的品种不同。</section><section style="margin: 0px;

text-indent: 2em; overflow-wrap: break-word !important;">其实就血型吸引蚊子理论的主要假说——分布在汗液和表皮中的不同血型抗原吸引了蚊子——本身而言，这种抗原分布的浓度如此之低，如Shirai的研究中所说，蚊子可能侦测不到。而根据蚊子的觅食习惯，侦测并找到远距离的目标对它们来说非常重要。目前比较明确的认识是，蚊子在寻找目标时，主要依赖的是二氧化碳、热量以及一些挥发性的化学物质，这些线索在空气中易于传播的特点大大提高了它们觅食的效率和成功率，是更好的选择。相比之下，身为糖脂的抗原不具备这个优势，目前也的确没有发现血型抗原对蚊子有什么确切的作用。</section><section style="margin: 0px;

1、网上流传的O型血招蚊子咬，没有科学依据。
2、统计数据显示：中国人70%是O型血。如果O型血招蚊子咬，那么人人都招蚊子咬了。
3、目前可以确定的所谓“不招蚊子”的，很多情况是那些人皮肤不敏感，被咬了也不感觉痒；组织胺应急分泌迟钝，咬了也不会起包。
4、蚊子喜欢的主要是下面5种人：
① 汗腺发达、体温高的人；
② 劳累和呼吸频率较快的人，即呼出二氧化碳多的人；
③ 胖人容易被蚊子叮咬；
④ 穿深色衣服的人容易被蚊子叮咬；
⑤ 婴幼儿代谢旺盛、呼吸频率快，蚊子尤其喜欢，儿童家中防蚊最好用蚊帐，或者安全的驱蚊产品。
由此可以断言，所谓容易招惹蚊子，该多从自身的个人卫生保持习惯方面查找原因。 O型血最容易招蚊子！我就是O型血的 跟蚊子的生存环境有关
