Mosquito name comes from a Spanish word meaning “little fly”. Basically mosquitoes feed on plant nectar, similarly to bees. Generally, we believe that mosquitoes bite humans because they need to feed on human blood, but this is not true. Actually, female mosquitoes suck blood in order to help with the development of their eggs prior to laying them. Male mosquitoes do not feed on blood at all.
Although at times mosquitoes are dangerous because of their ability to carry and transmit diseases. But we can’t deny the fact that mosquitoes also play an important role in the ecosystem because they serve as a food source for many organisms.
Though very small in size, mosquitoes are perhaps the only predator that has thrived through the centuries, causing death through vector-borne diseases. In fact, it is counted among the world’s deadliest, killing more than seven lakh people each year.
To raise awareness and alertness regarding the diseases caused by mosquitoes, world mosquito day was observed on August 20 every year. This day is also a remembrance day for Sir Ronald Ross who discovered a connection between female mosquitoes and malaria. In 1897, Sir Ronald Ross’s discovered that Anopheles mosquitoes transmit the malaria parasite to humans.

History of World Mosquito Day
1: Who was the first woman President of India?
World Mosquito Day, observed annually on August 20, commemorates a pivotal moment in medical history and serves as a global call to action against mosquito-borne diseases. The day marks the 1897 discovery by British doctor Sir Ronald Ross that female Anopheles mosquitoes transmit malaria to humans.
Before Ross’s groundbreaking research, the cause of malaria was a mystery, often attributed to “bad air” in marshy areas. His work in Secunderabad, India, provided definitive scientific proof of the mosquito’s role as a disease vector. This discovery fundamentally changed the understanding of malaria and laid the groundwork for modern prevention and control strategies. For this monumental achievement, Ross was awarded the Nobel Prize in Physiology or Medicine in 1902.
Ross himself proposed that the day be celebrated to raise public awareness about the connection between mosquitoes and malaria. Since the 1930s, the London School of Hygiene & Tropical Medicine has celebrated World Mosquito Day, and the tradition has since become a globally recognized event.
Today, World Mosquito Day is a platform used by organizations and individuals worldwide to:
- Educate the public about the risks posed by mosquito-borne illnesses, including malaria, dengue, Zika, chikungunya, and yellow fever.
- Highlight the ongoing efforts to combat these diseases through scientific research, vector control programs, and public health initiatives.
- Encourage people to take personal precautions and community-level actions to reduce mosquito populations.
- Acknowledge the contributions of scientists, healthcare professionals, and communities in the ongoing fight against these diseases.
The observance of World Mosquito Day is a powerful reminder that while significant progress has been made, mosquitoes remain one of the deadliest animals on the planet. Continued investment and effort are crucial to finally eradicating these illnesses.
