Acetylcholinesterase Activity in Fig Fly Zaprionus indianus Across Seasons

Jonathan De Oliveira Rios published this dataset on figshare in May 2026. It contains measurements of acetylcholinesterase (AChE) activity in the invasive fruit fly Zaprionus indianus, used as a biomarker for malathion exposure. The data likely includes spectrophotometric assay results and polyacrylamide gel electrophoresis patterns showing seasonal variation and isoenzyme differences between Brazilian populations.

Use Cases

• Modeling seasonal variation in enzyme activity based on the described spectrophotometric assays.
• Analyzing differential isoenzyme patterns between populations as mentioned in the description.
• Investigating biochemical biomarkers for organophosphate exposure based on the described AChE modulation.
• Studying potential adaptive responses to pesticide stress in an invasive species.

Strengths

• Data is published under a permissive CC-BY-4.0 license, allowing reuse with attribution.
• The dataset focuses on a specific biochemical biomarker (acetylcholinesterase) for a defined stressor (malathion).
• Analysis includes both spectrophotometric assays and polyacrylamide gel electrophoresis, suggesting methodological rigor.

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 very small at 189.0 KB, indicating limited scope.
