The Science of Mosquitoes: Attraction, Reproduction, and Disease Transmission
TLDR Mosquitoes have been around for millions of years and are attracted to humans by our carbon dioxide, body heat, and movement. They lay their eggs in water and spread diseases like malaria and yellow fever, but can be repelled using compounds like Ethyl pyruvate and Cyclopentanone.
Timestamped Summary
00:00
Mosquitoes are hated by everyone because they carry diseases and need blood to procreate, and they have been around for millions of years.
05:03
Mosquitoes are attracted to humans by the carbon dioxide and other volatile compounds we emit, as well as our body heat and movement, and they use their sensors to track and find us.
09:22
Mosquitoes are divided into different species, including the Aedes, Anopheles, and Culex, each with their own preferred breeding habitats and diseases they can spread.
13:47
Mosquitoes lay their eggs in water, and depending on the species, they can live from a few days to several weeks, with female mosquitoes needing a blood meal to lay eggs.
18:21
Mosquitoes lay eggs that hatch into larvae, which eventually become pupae and then adults through a process of molting, and once they become adults, they seek out a mate and a blood meal.
22:56
Mosquito bites cause an immune response in the form of a bumpy itch, and scratching the bite in an X pattern with a fingernail can actually alleviate the itch by limiting the immune response. Mosquitoes are also known for spreading diseases like malaria and yellow fever.
27:39
Mosquitoes are known for spreading diseases like yellow fever, encephalitis, West Nile virus, dengue fever, and worms that can cause blindness, but they do not spread HIV.
32:14
DEET, a common mosquito repellent, has been both maligned and embraced over the years, with concerns about its safety arising in the late 1990s and early 2000s due to reports of it being found in the umbilical cords of pregnant women and children having seizures after using it, leading to the development of alternative repellents such as lemon eucalyptus oil and soybean oil.
36:51
Mosquitoes can be repelled and baited using compounds like Ethyl pyruvate and Cyclopentanone, but mosquito traps and bug zappers are not effective in getting rid of them.
