Question

(b) Explain the events which occur within a female Anopheles mosquito after it has sucked blood from a malaria patient. 
 

Hint:

The development of Plasmodium in the mosquito’s gut and migration of sporozoites to the salivary glands are key for disease transmission.

Answer 1

- The gametocytes of Plasmodium enter the mosquito’s gut along with the blood meal. 
- In the mosquito's stomach: 
- The gametocytes develop into gametes. 
- The gametes fuse to form zygotes.
- The zygotes develop into sporozoites. 
- The sporozoites migrate to the mosquito’s salivary glands. 
- The mosquito is now ready to infect another host.
