Seasonal dynamics and core stability of the bacterial microbiome of a Drosophila suzukii wild population.

ABSTRACT: Drosophila suzukii (spotted-wing drosophila, SWD) is an invasive pest with pronounced sexual dimorphism and seasonal polyphenism. While seasonal morphotypes are well documented, how these phenotypic traits shape the SWD microbiome remains poorly understood. Here, we investigate how sex and seasonal phenotypes shape microbiome composition in SWD. We hypothesize that these factors drive microbial shifts, with some taxa varying between phenotypes and others forming a stable core. Understanding these patterns may reveal microbiome-associated adaptations relevant to SWD ecology and management. To investigate this, we monitored SWD microbiome dynamics over one year by collecting individuals during spring, summer, and autumn of 2022 and winter of 2023 from an organic farm in northern Portugal.
