Noseeums: Human Disease Transmission, Control and Personal Protection
Human Disease Transmission
Both C. furens and C. barbosai (especially the former) are vectors of Mansonella ozzardi, a human nematode parasite. This worm, which rarely produces symptoms of disease in infected people, is native to South America and has also been discovered on several islands in the West Indies. The worms live primarily in the blood, but juvenile forms (microfilariae) are also found in the skin. Female noseeums ingest the microfilariae when they take blood, and then transmit the parasite to uninfected people.
Control and Personal Protection
The effectiveness of controlling adult biting noseeum midges with insecticide sprays is mediocre at best, and also temporary in nature due to the continual emergence of these flies. Their larval habitats are so extensive that control in this manner is basically impossible. And unfortunately, mosquito control districts in Florida are not funded to provide control of no-see-ums, a.k.a. biting midges.
