India (1881–1899)
- The foundations of his research were laid in India. In 1889, he established the importance of mosquitoes as intermediate hosts in avian malaria. Soon afterwards, he discovered that the salivary gland was the storage site of malarial parasites in the mosquito, and that the parasites were released from the gland during biting.

Giovanni Battista Grassi (1854–1925)
- In 1890, the Italian physician, together with colleague Raimondo Filetti, first introduced the names Plasmodium vivax and P. malariae for two of the malaria parasites that affect humans. He also discovered that only female anopheline mosquitoes are capable of transmitting the disease.

Life cycle
- The mosquito goes through four separate and distinct stages of its life cycle: egg, larva, pupa, and adult. Depending on conditions, the life cycle can range from four days to as long as a month.

Mosquitoes and malaria - The disease is most commonly transmitted by an infected female Anopheles mosquito. This mosquito is a known malarial vector and can be found anywhere from Egypt all the way to China.

Aedes aegypti
- "Every year, her bite spreads diseases and parasites that kill almost one million people and cause debilitating illnesses in hundreds of millions more," notes the British biotechnology company.
