How Do Male Mosquitoes Eat?

Wouter

Unlike the female mosquito, the male doesn’t require a blood meal to survive. It feeds on plant nectar, honeydew, or the sap of various plants.

A male’s proboscis is designed to penetrate the skin. It is about as long as the female’s. The mandibles are about half the length of the female’s. These short, hooked teeth function as hooks that enable the mosquito to enter the skin.

The mosquitoes also use visual and chemical cues to locate nutrient sources. These include odors, tastants, and visual stimuli. However, the exact mechanisms of how the mosquito detects a sugar source are not well understood.

While all mosquitoes ingest nectar, only some species can store energy as larvae. A few species eat insects and other small animals. The others rely on plant nectar and water to meet their nutrition needs.

In addition to nectar, female mosquitoes also consume blood. These vectors transmit diseases to vertebrate hosts, and they transfer protozoan infections as well. For example, Culex quinquefasciatus, a mosquito known for malaria, prefers human blood.

When a female mosquito lays eggs, it needs a blood meal to produce them. Female mosquitoes do not need to ingest blood while in the pupal stage. The genitalia is where the eggs are released.

The larvae filter water using brush-like structures in the mouth. Their sack-like crop stores nectar and is connected to the fore-gut. It is full of minerals and sugars. A sugar deficiency can result in rapid mortality.
