Conteúdo:	In cases where a pest that is target of a Sterile Insect Technique (SIT) campaignis a member of a cryptic species complex, it is necessary to know in advance whetherthe sterile mass-reared males are sexually compatible with the wild females, otherwisethe releases would result in failure to induce sterility in the target population. The SouthAmerican fruit fly, commonly known as Anastrepha fraterculus, represents such a com-plex of cryptic species with at least 8 different morphotypes. From northern Argentinato southeastern areas of Brazil, the “Brazil-1” morphotype predominates and laboratorycolonies have been established for its control through the use of SIT. Our goal was toassess the mating compatibility between different populations, including two wild onesfrom southern Brazil (Vacaria-WV; and Pelotas-WP) and laboratory strains derived fromthis morphotype. These included two bisexual laboratory strains (Piracicaba-PIRA; andVacaria-VAC), and a recently developed genetic sexing strain, the GSS-89. Field cage testswith fertile flies demonstrated that PIRA flies present partial sexual incompatibility withall other strains, and therefore cannot be recommended for SIT field release. Also, malesof the VAC strain, both fertile and sterile, mated randomly with WV and WP flies. Noevidence of sexual isolation was found between the flies of the GSS and WV flies, but acertain level of incompatibility was shown between the fertile or sterile GSS males andWP females. Recommendations on the use of those strains through the SIT against thetwo southern Brazilian populations were made.
