Can Mosquitoes Breed in Salt Water?

Whether mosquitoes breed in salt water is still an ongoing debate. However, there are some species that are tolerant to salt and can lay eggs in this type of water.

The most tolerant of these mosquito species include Aedes aegypti and Anopheles gambiae. Their larvae can survive in water with a concentration of 2.0% salt. These mosquitoes show a survival curve in this water with a mean +- 1 SE over seven days.

During the rainy season, marshes are flooded with water. This is an ideal time for female mosquitoes to lay their eggs.

Some of the adult mosquitoes detect high salt concentrations and avoid feeding on them. They use tarsal segments to evaluate the source of nutrients. The adult females of these mosquitoes also ingest salts as components of plant-derived sugars. The amount of salts that the mosquitoes consume can vary depending on the water source.

The Culex salinarius mosquito breeds in freshwater and salt marshes. It is capable of flying up to eight miles from its breeding site. It prefers tropical climates.

Other mosquitoes that lay their eggs in salt water include Aedes solicitous and Anopheles taeniorhynchus. These mosquitoes are found in Australia and the United States.

In the United States, the house mosquito is the most common species of mosquito. It is a brown-colored insect with white markings. It bites during dusk and carries various diseases. It is often found in stagnant or polluted waters.

Some of these mosquitoes prefer to lay their eggs in dead plants. They can also be found in wetlands.
