  CRP - Improving Sterile Male Performance in Fruit Fly SIT programmes
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.

  Sterile atomic fly - Wikipedia, the free encyclopedia
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.
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.

 Getting rid of the tsetse fly
The Vienna-based International Atomic Energy Agency said in a statement the tsetse fly, which carries the parasite that causes sleeping sickness in humans and nagana in animals, was killing three million livestock animals every year.
"The impact of the fly is difficult to exaggerate," said John Kabayo, regional co-ordinator for the Pan African Tsetse and Trypanosomosis Eradication Campaign, inaugurated by the Organisation for African Unity.
Tsetse flies are bred in special centres and the males are exposed to a short burst of radiation, rendering them sterile.

 The development and application of the sterile insect technique (SIT) for New World screwworm eradication
Sexual sterility is induced by exposing the pupae to gamma rays, which damage the chromosomes in the sperm.
He realized that if sexual sterility could be induced in the males and if a means could be developed to rear, sterilize and release vast numbers of screwworm flies, the screwworm population in the United States could be reduced to insignificant numbers (Knipling, 1955, 1979).
Initially, the release of 78 sterile flies per square kilometre per week had little impact, but by increasing the rate of release to approximately 150 sterile flies per square kilometre per week eradication was achieved in just seven weeks (Lindquist, 1955).

Tsetse flies are bred in special centers and the males are exposed to a short burst of radiation, rendering them sterile.
After pesticides have sharply reduced the population, the sterilized males are released in large numbers into the breeding population, heavily outnumbering fertile males in the fight to mate.

 BBC News | Despatches | Zanzibar's sterilised tsetse flies
The latest experiment -- to eradicate the tsetse fly from the island of Zanzibar -- has been declared a success and the IAEA believes the technique should be extended to other parts of the world.
It was developed in the 1950s in the United States and involves using low doses of gamma radiation to sterilise insects, which are then released en masse into the wild.
The Atomic Energy Agency say it is in fact environmentally friendly because it removes the need for insecticides.

 UN Uses Atomic Technology To Fight Malaria Mosquito
People in poor, remote villages are usually unable to get treatment and so Knols's research aims to nip the problem in the bud by destroying the mosquito that transmits the malaria parasite.

 Sterile sex conquers sleeping sickness - 29 November 1997 - New Scientist
TSETSE flies, which spread sleeping sickness, have been eradicated from Zanzibar, an island off Tanzania's east coast, by the release of millions of sterile males.
The sterile male technique had previously been used to control the medfly, which attacks fruit crops across the Americas, and the New World screw worm, whose larvae eat into the flesh of livestock.
Now the plan is to extend the tsetse programme to the African mainland, where 300 000 people are infected with the trypanosome parasites that cause sleeping sickness.
