(1) Background: Seasonal dynamics of the abundance and species diversity of various insect groups is of great importance for understanding their life cycles; (2) Methods: In our study, Drosophilidae species and their seasonal changes in Mordovia State Nature Reserve were explored. We collected the flies by crown fermental traps in five types of forests (birch, aspen, linden, pine and oak) since May to October in 2019. (3) Results: A total of 4725 individuals belonging to 9 genera and 30 species of drosophilid flies were identified, among them 15 species in 3 genera are new to the Republic of Mordovia. and were the most abundant species in traps, the other mass species are and . (4) Conclusions: We found three groups of mass species with significant correlation of seasonal dynamics, e.g., D.obscura and and , and, finally, and . Apparently, the similarity observed in the seasonal dynamics of these drosophilid species is influenced at a high degree by their food preferences and rearing sites.
(1) 背景：各类昆虫群体的丰度和物种多样性的季节性动态对于理解它们的生命周期至关重要；(2) 方法：在我们的研究中，对莫尔多瓦州自然保护区的果蝇科物种及其季节性变化进行了探索。2019年5月至10月期间，我们在五种类型的森林（桦树、白杨、椴树、松树和橡树）中使用树冠发酵诱捕器收集果蝇。(3) 结果：共鉴定出4725只属于9属30种的果蝇，其中3属15种对莫尔多瓦共和国来说是新物种。 和 是诱捕器中数量最多的物种，其他数量较多的物种是 和 。(4) 结论：我们发现了三组数量较多的物种，它们的季节性动态具有显著相关性，例如，黑腹果蝇与 和 ，以及最后 和 。显然，这些果蝇物种在季节性动态中观察到的相似性在很大程度上受到它们的食物偏好和繁殖地点的影响。
