The Sterile Insect Technique (SIT) is a system based on the release of millions of sterile insects to prevent the reproduction of specific pest populations. However, to improve the efficacy of the SIT, sterile males must reach sexual maturity before being released to increase their probability of mating with wild females. Treatments with juvenile hormone (JH) analogs, such as pyriproxyfen (PPF), accelerate sexual maturity in sterile Anastrepha ludens (Loew) (Diptera: Tephritidae) males. We hypothesized that speeding up this life-history trait can affect male resistance to stressors such as chilling and starvation. In this study, we compared some quality control parameters of flies of two different strains, selected to resist desiccation (DR) and non-selected flies (NS), treated with PPF, and subsequently exposed to starvation and pre-release chilling periods. We used males that were treated with PPF after emergence. The results showed that, from 4 to 6 days of age, DR PPF-fed males mated less than NS PPF-fed males. DR and NS males obtained a similar number of copulations at 7 days of age. After chilling, survival was higher in DR than in NS males. In addition, NS males showed a slight advantage in number of copulations when they reached 5 days of age but not at 6 and 7 days of age. Chill-coma recovery time was longer in PPF-fed flies than in control flies. Moreover, PPF-fed flies obtained less copulations after exposure to chilling at 5 days of age compared to non-chilled flies. These results indicate that sexual maturity is accelerated in PPF-fed males, especially in NS flies. However, using PPF as a pre-release treatment for A. ludens results in a reduction in male quality, regardless of whether they are DR or NS.

昆虫不育技术（SIT）是一种基于释放数百万只不育昆虫以防止特定害虫种群繁殖的系统。然而，为了提高昆虫不育技术的效果，不育雄性在被释放之前必须达到性成熟，以增加它们与野生雌性交配的可能性。使用保幼激素 (JH) 类似物（例如吡丙醚 (PPF)）治疗可加速不育按蚊 (Loew)（双翅目：实蝇科）雄性的性成熟。我们假设，加速这种生活史特征可以影响男性对寒冷和饥饿等压力源的抵抗力。在这项研究中，我们比较了两种不同品系果蝇的一些质量控制参数，选择抗干燥（DR）和非选择果蝇（NS），用PPF处理，随后暴露于饥饿和释放前的冷冻期。我们使用羽化后接受 PPF 治疗的雄性。结果显示，从 4 到 6 天龄，DR PPF 喂养的雄性交配次数少于 NS PPF 喂养的雄性。 DR 和 NS 雄性在 7 日龄时获得相似的交配次数。冷冻后，DR 雄性的存活率高于 NS 雄性。此外，NS雄性在5日龄时在交配次数方面表现出轻微优势，但在6日龄和7日龄时则没有。 PPF 喂养的果蝇的寒昏恢复时间比对照果蝇更长。此外，与未冷藏的果蝇相比，PPF 喂养的果蝇在 5 日龄暴露于寒冷环境后获得的交配次数较少。这些结果表明，PPF 喂养的雄性，尤其是 NS 果蝇，性成熟加速。然而，使用 PPF 作为鲁登丝虫的预释放处理会导致雄性质量下降，无论它们是 DR 还是 NS。
