Is it true mosquito or IQ tax?Japan launches simulated dragonfly to prevent mosquitoes

Science Fiction Network July 5th (Wang Ziyu) In addition to the hot weather in summer, the buzzing mosquito is also annoying. With flexible flight, people's eyes were full of hatred. Of course, mosquitoes also have natural enemies, that is, dragonflies, some studies have shown that dragonflies have eaten mosquitoes for 100 million years.

Based on this, a Japanese manufacturer created a bionic dragonfly. It is reported that the simulation dragonfly was made into a pendant, and the single price was 98 yuan, claiming that as long as it was worn, the mosquito could be kept away from you. However, does this simulation dragonfly really have a mosquito repellent effect?

Dragonfly is a common insect, which is mainly distributed in tropical and subtropical regions. There are about 500 types in the world. In nature, the relationship between dragonflies and mosquitoes has always been preferentially preferential. Because Dragonfly is carnivorous insects, it eats a variety of agricultural, forestry and animal husbandry pests such as flies, mosquitoes, and leafy. During the nymph, the dragonfly used mosquito larvae as a food source.

Although the dragonfly eats mosquitoes, this is just a simulated dragonfly, and it does not play the effect of mosquito repellent. What's more, mosquito is a sense of smell, vision, and calories to perceive the world. Its sense of smell can smell the carbon dioxide produced by human breathing 50 meters away. Within about 5-10 meters, mosquitoes can lock the host by relying on vision to lock the host. Human position. In less than 1 meter distance, mosquitoes can detect the body temperature of the host, and then start biting.

Even if the simulation dragonfly does, it is almost equivalent to the effect of mosquito repellent. If you want to reduce the number of mosquito bites, the best way is to reduce the smell that mosquitoes like or increase the odor that mosquitoes do not like.
