  • The Sterile Insect Technique (SIT) is another approach to reduce tsetse populations. This technique is based on the fact that females mate only once in their lifetime, thus any mating with a sterile male will prevent females from giving birth to any offspring. SIT consists in rearing a large numbers of laboratory male tsetse flies which are irradiated and subsequently released in the wild to compete with wild (naturally occurring) males so that females inseminated by them produce no off-spring. The technique has been effectively used for eradication of tsetse (G. Austeni) from Unguja island in Zanzibar.  WHO Vector control
