Cadmium Stress Effects on Tomato-Thrips-Predator System: Physiology and Biological Control

Jie Wang's dataset from figshare, last updated May 14, 2026, investigates the cascading effects of cadmium contamination on a tomato plant, western flower thrips, and minute pirate bug predator system. The 74.0 KB XLSX file contains results from analyses of plant photosynthetic physiology, untargeted metabolomics, and insect fitness, behavior, and cadmium accumulation. The study quantifies reductions in photosynthesis, insect survival, predation rates, and cadmium transfer through the food chain.

Use Cases

• Modeling cadmium transfer and bioaccumulation through a tri-trophic food chain based on the described accumulation data.
• Analyzing the impact of heavy metal stress on predator-prey dynamics based on the reported predation and oviposition rate changes.
• Investigating plant physiological and metabolic pathway responses to cadmium exposure based on the differential metabolites and photosynthetic metrics.
• Assessing the fitness and behavioral responses of pest and beneficial insect species under environmental stress based on the survival and preference assay results.

Strengths

• Includes quantified physiological impacts: specific reductions in net photosynthetic rate (Pₙ), transpiration rate (Tᵣ), stomatal conductance (Gₛ), and intercellular CO₂ concentration (Cᵢ).
• Reports specific effect sizes: 17.0%–31.0% reduction in thrips survival, 14.1%–24.3% reduction in predator predation rate, and 46.4% decrease in predator oviposition.
• Integrates multiple analysis methods: plant physiology, untargeted metabolomics (identifying 348 differential metabolites), and insect behavioral assays.
• Data is openly available under a CC-BY-4.0 license.

Limitations

• Row count is unknown, which may limit suitability assessment.
• Column-level documentation is absent; field semantics must be inferred after download.
• The dataset is small (74.0 KB), indicating a limited scope likely focused on the results of a single controlled study.
