Resumen:
If a genetic sexing strain of Ceratitis capitata could be used to produce sterile males and to rear parasitoids at the same time, significant
amount of resources could be saved in comparison with the production of these two biological agents separately. We studied here the
major biological parameters comparing two strains of the parasitoid Diachasmimorpha longicaudata, one of them reared on a wild type
strain of C. capitata: DL(+), and the other on a genetic sexing strain of C. capitata: DL(sw). The mean longevity, fecundity, and sexual
proportion of their respective offspring showed no significant diference. Moreover, no difference was observed in population parameters
such as mean generation time, net reproductive rate, finite rate of increase, doubling time, and intrinsic rate of increase. The biological
parameters of other artificially reared parasitoids in the Tephritidae family are reviewed, and the conclusion is reached that, rearing the
parasitoid on this particular genetic sexing strain of C. capitata does not produce any negative effect on the biological parameters studied.Ceratitis capitata could be used to produce sterile males and to rear parasitoids at the same time, significant
