The characteristics of the juvenile developmental environment of an individual can have many important consequences for their adult reproductive success as it may shape the development and expression of phenotypes that are relevant to the later operation of sexual selection. Drosophila suzukii (Matsumura) (Diptera: Drosophilidae) is an economically important invasive pest species that lays its eggs in many types of soft fruits and potentially experiences large intrapopulation spatial and temporal variation in its nutritional developmental environments. Here, we examine whether the larval nutritional developmental environment influences D. suzukii mate choice, egg production, and offspring performance. Using D. suzukii raised on diets differing in their nutritional quality, we examined mating preferences, fecundity, and offspring survivorship in “no-choice,” “female choice,” and “male choice” reproductive contexts. We found evidence for both adaptive and nonadaptive mate choice behaviours associated with the phenotypes of D. suzukii that had developed in different nutritional environments. These results reveal the complex nature of the relationship between the developmental environment and individual reproductive success in D. suzukii, which has important potential implications for future management plans involving this species.

个体的青少年发育环境的特征可能对其成年生殖成功产生许多重要影响，因为它可能影响与以后进行性选择有关的表型的发展和表达。铃木果蝇（松果蝇）（双翅目：果蝇科）是一种经济上重要的入侵害虫，可将其卵产于多种类型的软果中，并可能在其营养发育环境中经历种群内时空变化。在这里，我们检查幼虫的营养发育环境是否会影响铃木D.的配偶选择，产蛋量和后代性能。使用铃木D.通过在营养质量上不同的饮食中成长，我们研究了在“无选择”，“女性选择”和“男性选择”生殖环境中的交配偏好，繁殖力和后代存活率。我们发现了与在不同营养环境中发育的铃木D.表型相关的适应性和非适应性伴侣选择行为的证据。这些结果揭示了铃木D.的发育环境与个体生殖成功之间关系的复杂性质，这对于涉及该物种的未来管理计划具有重要的潜在影响。
