How do adult female mosquitoes acquire protein for egg production?

Adult female mosquitoes require protein for the development of their eggs, and they acquire this essential nutrient primarily through the consumption of blood from hosts. Blood serves as a significant source of proteins and other nutrients necessary for oogenesis, the process of egg development. When a female mosquito bites a host, she feeds on blood, which provides the proteins that are crucial for the synthesis of her eggs.

In contrast, while feeding on nectar from flowers or consuming plant sap can provide carbohydrates to fuel their energy needs, these options do not supply the required proteins for egg production. Additionally, although female mosquitoes can rely on stored fat reserves during periods when a blood meal is not available, this method is not their primary means for acquiring the necessary proteins for egg development. Hence, feeding on blood is the primary and most effective way for female mosquitoes to obtain the protein needed for their reproductive cycle.
