Abstract

The Drosophila genus comprises over 2000 species worldwide, making it a valuable model for studying habitat selection and preference differences among species in specific ecosystems. This review focuses on the differences in habitat and chemical preference between Drosophila melanogaster, which inhabits overripe and decaying fermented fruits, and D. suzukii, which inhabits fresh and ripe fruits. First, we discuss habitat characteristics associated with differences in chemical preference between the two Drosophila species and examine the correlation between chemical attraction and sensory adaptations. In addition, considering the sequential production of various volatile compounds such as 2-phenylethanol, ethanol, and acetic acid during the fermentation and decay processes of fruits, we provide a molecular-physiological interpretation of the differences in chemical tolerance and tolerance-related gene expression. Furthermore, we propose a novel relationship between the immune response and chemical tolerance, offering new insights into the study of immune pathways in fruit flies. Building on recent findings, we outline future directions for research into the molecular mechanisms of chemical interactions and adaptive strategies of D. melanogaster and D. suzukii.

黑腹果蝇和铃木果蝇对不同生境的适应机制
果蝇属在世界范围内有超过2000种,使其成为研究特定生态系统中物种之间栖息地选择和偏好差异的有价值的模型。本文综述了黑腹果蝇(Drosophila melanogaster)以过熟和腐烂的发酵水果为食,铃木姬果蝇(d.s uzukii)以新鲜和成熟的水果为食,两者在栖息地和化学偏好方面的差异。首先,我们讨论了与两种果蝇之间化学偏好差异相关的栖息地特征,并研究了化学吸引与感觉适应之间的相关性。此外,考虑到水果在发酵和腐烂过程中顺序产生的各种挥发性化合物,如2-苯乙醇、乙醇和乙酸,我们提供了化学耐受性和耐受性相关基因表达差异的分子生理学解释。此外,我们提出了一种新的免疫反应与化学耐受性之间的关系,为果蝇免疫途径的研究提供了新的见解。在此基础上,展望了黑腹扁霉和铃木扁霉化学相互作用的分子机制和适应策略的研究方向。
