  abstract = {{S}imple {S}ummary {T}he {S}terile {I}nsect {T}echnique consisting of inundative and repeated releases of sterile males that induce sterility in the wild population is currently tested as a new strategy to control {A}e. albopictus. {C}onsidering that {A}e. albopictus and {A}e. aegypti thrive in sympatry in some regions, and that mating between both species is known to occur at low rates, we hypothesize that releasing millions of sterile male {A}e. albopictus in could affect female {A}e. aegypti reproduction. {T}o study this potential mating interference, the newly established marking technique has been applied using the rhodamine {B} that is administered to males through sugar meal. {I}t is internally incorporated into the mosquito's male body and during mating, the rhodamine is transferred into the females. {I}n laboratory-based experiments rhodamine marking proved to be a powerful means of detecting mating in females of both {A}edes species, whatever the mating crosses between males and females. {S}ome mated females were able to lay eggs, but all were not viable. {H}owever, despite the promiscuity of the adults in small experimental cages, 95% of the female {A}e aegypti showed no evidence of insemination following mating with sterile male {A}e. albopictus, suggesting that in the field, an inundative and repeated releases of sterile male {A}e. albopictus will not influence the reproduction of female {A}e aegypti. {I}n {R}eunion {I}sland, the feasibility of an {A}edes albopictus control program using the {S}terile {I}nsect {T}echnique ({SIT}) is studied. {B}ecause, in some regions, {A}e. albopictus is living in sympatry with {A}edes aegypti, the impact of releasing millions of sterile male {A}e. albopictus on female {A}e. aegypti reproduction needs to be assessed. {T}hus, to study the potential heterospecific matings, a marking technique using rhodamine {B} has been used. {R}hodamine is given in solution to male mosquitoes to be incorporated into the male body and seminal fluid and transferred during mating into the bursa inseminalis and spermathecae of females. {T}he presence of rhodamine in females occurred in 15% of cases when {A}e. aegypti females were offered non-irradiated {A}e. albopictus males, 5% when offered irradiated {A}e. albopictus males and 18% of cases in the inverse heterospecific matings. {M}oreover, our results also showed that these matings gave few eggs but were not viable. {F}inally, the results showed that whatever the type of mating crosses, females in cages previously crossed with males of another species can re-mate with males of their species and produce an equivalent amount of egg compared to females only mated with conspecific males. {D}espite the promiscuity of the males and females in small cages for three days, heterospecific mating between sterile male {A}e. albopictus and female {A}e aegypti, 95% of the females have not been inseminated suggesting that in the field the frequency satyrization would be very low.},
