Title: Necrosis is a major driver of thermal stress-induced mortality in Drosophila melanogaster larvae: cellular and molecular insights across acclimation phenotypes Authors: Fatemeh Saeidi & Hervé Colinet Affiliation: Université de Rennes, CNRS, ECOBIO (Ecosystèmes, biodiversité, évolution) – UMR 6553, 35000 Rennes, France This repository contains raw data files (in .txt format) associated with the study investigating cell death dynamics induced by cold (-3°C) and heat (38°C) stress in third-instar Drosophila melanogaster larvae. The study compared three acclimation phenotypes: - LNA: Non-acclimated larvae (reared at 25°C for 4 days) - LCA: Cold-acclimated larvae (reared at 15°C for 10 days) - LHA: Heat-acclimated larvae (reared at 30°C for 3 days) All data files are in tab-delimited text format (.txt). For detailed statistical methods, please refer to the Materials & Methods section of the associated manuscript. LNA : Non-acclimated larvae (reared at 25°C for 4 days) LCA : Cold-acclimated larvae (reared at 15°C for 10 days) LHA : Heat-acclimated larvae (reared at 30°C for 3 days) BS : Black spots (melanized lesions) NBS : No black spots Co : Unstressed control CTCF : Corrected total cell fluorescence ROS : Reactive oxygen species GLM : Generalized linear model GLMM : Generalized linear mixed model PCA : Principal component analysis RpL32 : Reference gene used for normalization

This repository contains raw data files (in .csv format) associated with a study investigating the role of composters in maintaining Drosophila suzukii populations. Nine experimental composters were monitored over two years using emergence traps and continuous temperature recording. A total of 95,322 Drosophilidae were captured from composters over the study period, of which 7,377 were D. suzukii. (2026-04-10)
