Several species have been accidentally introduced from other parts of the world. Worldwide, mosquito-borne diseases kill more people than any other single factor. Most species can produce several batches of eggs during their lifetime. Depending on temperature, Mosquitoes can develop from an egg to an adult in as little as 4 to 7 days. The larvae are filter feeders of organic particulates.
Adults can live for several weeks, feeding on carbohydrate sources such as nectar and fruit juices.
Presently, the cues used by mosquitoes are poorly understood. Carbon Dioxide and heat have been shown experimentally to be attractants. Other compounds tested, such as lactic acid and octenol, have had mixed results.
