  abstract = {{B}ackground: {T}setse flies are the cyclical vectors of {A}frican trypanosomosis that constitute a major constraint to development in {A}frica. {T}heir control is an important component of the integrated management of these diseases, and among the techniques available, the sterile insect technique ({SIT}) is the sole that is efficient at low densities. {T}he government of {B}urkina {F}aso has embarked on a tsetse eradication programme in the framework of the {PATTEC}, where {SIT} is an important component. {T}he project plans to use flies from a {G}lossina palpalis gambiensis colony that has been maintained for about 40 years at the {C}entre {I}nternational de {R}echerche-{D}eveloppement sur l'{E}levage en zone {S}ubhumide ({CIRDES}). {I}t was thus necessary to test the competitiveness of the sterile males originating from this colony. {M}ethodology/{P}rincipal {F}indings: {D}uring the period {J}anuary-{F}ebruary 2010, 16,000 sterile male {G}. p. gambiensis were released along a tributary of the {M}ouhoun river. {T}he study revealed that with a mean sterile to wild male ratio of 1.16 (s.d. 0.38), the abortion rate of the wild female flies was significantly higher than before (p = 0.026) and after (p = 0.019) the release period. {T}he estimated competitiveness of the sterile males ({F}ried index) was 0.07 (s.d. 0.02), indicating that a sterile to wild male ratio of 14.4 would be necessary to obtain nearly complete induced sterility in the female population. {T}he aggregation patterns of sterile and wild male flies were similar. {T}he survival rate of the released sterile male flies was similar to that observed in 1983-1985 for the same colony. {C}onclusions/{S}ignificance: {W}e conclude that gamma sterilised male {G}. p. gambiensis derived from the {CIRDES} colony have a competitiveness that is comparable to their competitiveness obtained 35 years ago and can still be used for an area-wide integrated pest management campaign with a sterile insect component in {B}urkina {F}aso.},
