    The raw data is associated with the paper "Sulfoxaflor modulates diet-dependent effects on bumble bee development but shows no detectable effects on adult physiology" By Margret Jürison, Pilleriin Teras, Kaarel Pent, Vivika Väli, Risto Raimets, Sigmar Naudi, Angela Ploomi, Marika Mänd, Reet Karise 1. raw_data__mortality.csv This dataset contains the raw survival data used for the Kaplan-Meier survival analysis in the associated publication. Each row represents one individual bumble bee. The columns are described as follows: Treatment: The diet or exposure group Time: The survival time recorded for the individual (e.g., days). Status: Survival outcome, where 1 = dead and 0 = censored (alive at end of observation). 2. raw_data_respiratory_measurements.xlsx This file contains the CO2 measurements (in µmol/mol) recorded in the study. Each column corresponds to a single bumble bee, and each sheet represents a different treatment group. The columns are described as follows: time_s: time in seconds at which the LI-7000 (LiCor, Lincoln, NE) device logged CO2 release in bumble bees co2_...: CO2 measurements for each individual bee.

    Sulfoxaflor modulates diet-dependent effects on bumble bee development but shows no detectable effects on adult respiration rate and patterns : [data]
    (Estonian University of Life Sciences, 2026) Jürison, Margret; Teras, Pilleriin; Pent, Kaarel; Väli, Vivika; Raimets, Risto; Naudi, Sigmar; Ploomi, Angela; Mänd, Marika; Karise, Reet
    Pollinators face multiple stressors, including pesticide exposure and poor nutrition, yet their combined effects on developing brood remain poorly understood. In this study, we experimentally reared bumble bee (Bombus terrestris) larvae on pollen diets differing in protein-to-lipid (P:L) ratios and exposed them to the insecticide sulfoxaflor via their food to test how these factors jointly affect survival, development, and adult traits. Larvae fed multifloral pollen exhibited higher survival and more consistent growth than monofloral (oilseed rape, faba bean) diets. Under the oliseed rape, sulfoxaflor reduced mortality and increased adult emergence despite poorer baseline performance in controls. In contrast, under the multifloral diet, sulfoxaflor prolonged development, reduced larval growth, and lowered adult body mass. Under faba bean, responses varied across traits, with prolonged development at lower exposure and reduced growth at higher exposure. Despite these developmental effects, sulfoxaflor did not significantly affect adult respiration rate, and respiration patterns showed no significant treatment effects, although diet-dependent trends were observed. These findings demonstrate that sulfoxaflor effects are strongly context-dependent and mediated by nutritional conditions. They indicate that sulfoxaflor shifts diet-dependent trade-offs between survival and development, improving survival on nutritionally limiting diets while imposing developmental delays and growth costs when nutrition is otherwise favourable.
