The effect of time of pupariation on pupal weight and adult sexual competitiveness under field cage conditions was studied in mass-reared Anastrepha ludens (Loew) males. Larvae that took 72 h to pupariate after separation from diet resulted in lighter pupae than those that took 24 and 48 h. Wild pupae were heavier than the 48- and the 72-h pupae but not the 24-h pupae. Interestingly, no differences in mating performance were found between males of the 24- and 48-h pupae despite differences in pupal weight. In general, lower-than expected levels of mating compatibility between sterile and wild A. ludens resulted from the interaction of both strains as more homotypic pairs were observed. Discussion focuses on the effect of the mass-rearing process on male fruit fly mating performance.
在大规模饲养的墨西哥按实蝇（Loew）雄性果蝇中，研究了化蛹时间对野外笼养条件下蛹重和成虫性竞争力的影响。与食物分离后72小时化蛹的幼虫形成的蛹比24小时和48小时化蛹的幼虫形成的蛹更轻。野生蛹比48小时和72小时化蛹的蛹重，但不比24小时化蛹的蛹重。有趣的是，尽管蛹重存在差异，但24小时和48小时化蛹的雄性果蝇在交配性能上没有发现差异。总体而言，不育和野生墨西哥按实蝇之间的交配兼容性低于预期水平，这是由于两种品系的相互作用导致观察到更多同型配对。讨论集中在大规模饲养过程对雄性果蝇交配性能的影响。
