Insecticidal and Repellent Activities of Allium Extracts Against Grapevine Mealybug

Tokozani Mange's dataset contains results from a study evaluating the bioactivity of extracts from three Allium species (garlic, onion, leek) against the grapevine mealybug (Planococcus ficus). The data likely includes measurements of repellent efficacy and insecticidal potency for different plant species and extraction solvents, such as acetone and DCM. The study received ethical approval from the Faculty Research Ethics Committee at CPUT.

Use Cases

• Comparing repellent efficacy of different Allium species extracts based on reported statistical results.
• Analyzing the insecticidal potency of garlic extract in different solvents (e.g., DCM) against Planococcus ficus.
• Evaluating the performance of an organic soap formulation of garlic extract based on its 38% repellency metric.
• Statistical re-analysis of bioassay results using the reported degrees of freedom (DF), chi-square, and p-values.

Strengths

• Dataset is openly available under a CC-BY-NC-SA-4.0 license, permitting non-commercial reuse with attribution.
• The underlying study design includes specific, reported statistical results (e.g., DF=3; χ2=19.95; P<0.05).
• Cross-platform presence on figshare indicates established sharing and potential for reuse.

Limitations

• Column names and a precise row count are not provided, limiting understanding of the data's structure.
• The dataset's size (17070) is given, but its unit (likely bytes) and relation to data completeness are unclear.
• The 'last updated' date of 2026-03-24 is a future date, creating a conflict in metadata reliability.
