Do male mosquito bite if they do why they don't transmit malaria?

Yes, male mosquitoes do bite, but they do not transmit malaria. Only female mosquitoes transmit malaria. Female mosquitoes require the blood meal to develop and nourish their eggs, while male mosquitoes feed on nectar and plant juices. Additionally, malaria-causing parasites (Plasmodium) are typically found in female mosquitoes' salivary glands, allowing them to transmit the disease when they bite a human.
Why only female anotheles mosquito transmit malaria not male?
Only female Anopheles mosquitoes transmit malaria, and there are a few reasons for this:
1. Feeding Behavior: Female mosquitoes need a blood meal to develop and nourish their eggs, while male mosquitoes feed solely on nectar and plant juices. The blood meal provides the necessary proteins for egg development.
2. Parasite Transmission: Malaria-causing parasites of the Plasmodium genus need to go through a complex life cycle, which involves both the mosquito and a human host. When a female Anopheles mosquito bites an infected person, it can ingest the parasite from the person's blood. The parasites then develop and multiply inside the mosquito, eventually migrating to the mosquito's salivary glands. When the infected female mosquito bites another person, it injects the parasites along with its saliva, transmitting malaria.
3. Immune Response: Male mosquitoes do not have a role in reproduction involving egg development, so they do not require a blood meal. Besides, the male mosquito's immune system is typically more effective in clearing the malaria parasite if it happens to be infected. This stronger immune response helps prevent the parasite from reaching the salivary glands, reducing the likelihood of transmission.
Therefore, the combination of feeding behavior, the need for a blood meal for egg development, and the female mosquito's role in Plasmodium transmission make only female Anopheles mosquitoes capable of transmitting malaria.
