Resumen:
The preferences of the Neotropical eucoline species Aganaspis pelleranoi (Brèthes) for larvae of both Anastrepha fraterculus (Wiedemann) and Ceratitis capitata (Wiedemann) were evaluated under laboratory conditions in no-choice and dual-choice tests, based on percent parasitism, proportion of emerged parasitoids, proportion of female offspring, and number of parasitoid female visits to and ovipositor probes on the artificial oviposition device as different measures of host preference. In no-choice tests A. pelleranoi females did not demonstrate a significant preference between C. capitata and A. fraterculus larvae. Nevertheless, A. Pelleranoi females showed a weak preference for A. fraterculus larvae in dual-choice test. Although female biased parasitoid progeny resulted in all assays, significantly more A. pelleranoi female offspring emerged from A. fraterculus pupae than from C. capitata pupae. Thus, this study confirmed that both C. capitata and A. fraterculus are appropriate host for rearing the native A. pelleranoi, but also provided evidence that female parasitoid progeny yield can be improved by using A. fraterculus larvae as the host for rearing instead of C. capitata larvae.
