Description
Levubu, Limpopo Province, South Africa is the study area for this dataset underpinning an MSc dissertation. It contains measurements of soil nutrients, plant sap, leaf nutrients, and tree physical traits across four macadamia cultivars to examine their influence on thrips abundance and nut damage. The dataset was authored by Ntombizwodwa Luvhimbi and last updated on June 3, 2026.
Use Cases
Predict thrips abundance based on soil nutrient principal components derived from the described variables.
Analyze the relationship between specific thrips species (Scirtothrips aurantii, Thrips tenellus) and macadamia cultivar susceptibility.
Model nut damage incidence across different developmental stages (flowering, nut-set, 1–1.5 cm nut diameter).
Investigate correlations between tree physical traits (canopy height, diameter, density) and pest pressure.
Strengths
Data includes measurements across three distinct nut developmental stages and four macadamia cultivars.
Identifies the two most prevalent thrips species, which comprised 98.9% of all thrips sampled.
Principal component analysis was performed on soil, sap, and leaf nutrient variables, as described.
Limitations
Column-level documentation is absent; field semantics must be inferred after download.
Row count is unknown, which may limit suitability assessment.
The dataset's 567.4 KB size indicates a limited scope, likely from a single study region and time period.
