Confronting environments with low relative humidity is one of the main challenges faced by insects with expanding distribution ranges. (the Mexican fruit fly) has evolved to cope with the variable conditions encountered during its lifetime, which allows it to colonise a wide range of environments. However, our understanding of the mechanisms underpinning the ability of this species to confront environments with low relative humidity is incomplete. In this sense, omic approaches such as transcriptomics can be helpful for advancing our knowledge on how this species copes with desiccation stress. Considering this, in this study, we performed transcriptomic analyses to compare the molecular responses of laboratory-reared exposed and unexposed to desiccation. Data from the transcriptome analyses indicated that the responses to desiccation are shared by both sexes. We identified the up-regulation of transcripts encoding proteins involved in lipid metabolism and membrane remodelling, as well as proteases and cuticular proteins. Our results provide a framework for understanding the response to desiccation stress in one of the most invasive fruit fly species in the world.
面对相对湿度低的环境是分布范围不断扩大的昆虫面临的主要挑战之一。（墨西哥实蝇）已经进化到可以应对其一生中遇到的多变条件，这使其能够在广泛的环境中生存。然而，我们对该物种应对低相对湿度环境的能力的机制的理解还不完整。在这方面，转录组学等组学方法可以帮助我们更多地了解该物种如何应对干旱胁迫。有鉴于此，在这项研究中，我们进行了转录组分析，以比较实验室饲养的 和未暴露于干旱的 的分子反应。转录组分析的数据表明，对干旱的反应在两性中是共享的。我们鉴定了编码参与脂质代谢和膜重塑以及蛋白酶和角质蛋白的转录本的上调。我们的结果为理解世界上最具入侵性的实蝇之一对干旱胁迫的反应提供了一个框架。
