Encyclopedia > Sterile Atomic Fly

The sterile atomic fly, one kind of sterile insect technique, is an innovative solution to the problem of sleeping sickness, and is being developed by the United Nations and the International Atomic Energy Agency, building on their experience of similar programs over past decades against the fruit fly in Australia and Africa. El Salvador successfully demonstrated the sterile insect technique eliminating the malaria causing mosquito, from a region for a period of time. ...

Sleeping sickness or African trypanosomiasis is a parasitic disease in humans. Caused by protozoa of genus Trypanosoma and transmitted by the Tsetse fly, the disease is endemic in certain regions of Sub-Saharan Africa, covering about 36 countries and 60 million people. It is estimated that 300,000 - 500,000 people are infected, and about 40,000 die every year. Three major epidemics have occurred in the past hundred years, in 1896 - 1906, 1920, and 1970.

Studies of the tsetse fly show that females generally only mate once in their lifetimes and very rarely mate a second time. Once a female fly has mated, she can then produce continual offspring throughout her short life.


Using this information, the International Atomic Energy Agency has developed a process of irradiating male Tsetse flies that have been specially bred. This process of irradiation sterilizes the male. These sterilized male flies are then released into areas where Sleeping sickness is prevalent, and then mate with the females. Because the male is sterile, and the females mate only once, the population of Tsetse flies in the affected area will drop. Studies have shown that this process has been very effective in preventing Sleeping sickness in people who live in the area. The IAEA flag The International Atomic Energy Agency (IAEA), established as an autonomous organization on July 29, 1957, seeks to promote the peaceful use of nuclear energy and to inhibit its use for military purposes. ... Irradiation is the process by which an item is exposed to radiation. ...


Since sleeping sickness is fatal without treatment and infected people can be without symptoms for months, the release of sterile atomic flies into affected areas leads to greater levels of health and economic activity.

Fly density and the amount of surface area available for flies to rest on are important factors to consider in order to avoid overcrowding and stressing the flies.
In the case of aerial releases, the flies must be extracted from the temporary containers through the use of cold fly knockdown methods, and then transferred to aerial drop boxes, which are transported to waiting aircraft.
Sterile males, between 3-11 days old, fed a methoprene containing diet, released significantly more pheromone and were significantly more attractive to fertile females than were sterile males denied hormone in the diet.
