Drosophila Suzukii Fitness Traits and Lipid Composition on Cactus Diet

Figshare data compiles phenotypic, life-history, and physiological measurements of the invasive pest fly Drosophila suzukii reared on Opuntia sulphurea cactus and standard lab diets. Lucas Kreiman authored the dataset, which was last updated in April 2026. The 42.9 KB collection includes six datasets covering viability, development time, ovariole count, wing length, substrate acceptance, and fatty acid profiles.

Use Cases

• Compare development_time and viability across three Diet types (cactus-based, potato flakes, cornmeal) to assess host plant suitability.
• Analyze the Lipid profile proportions of 11 specific fatty acids (e.g., C16:0, C18:2) to understand how diet influences insect physiology.
• Correlate wing_length measurements with ovariole_number per female to study trade-offs between dispersal and reproduction.
• Model egg Acceptance rates on agar versus cactus substrates using counts of eggs laid and larvae hatched.
• Account for temporal effects in analyses using the Block variable representing the year/date of measurement.

Strengths

• Includes six distinct datasets measuring multiple fitness dimensions: viability, development, morphology, and lipid chemistry.
• Provides detailed explanatory variables: Diet (3 types), Block for temporal control, and Individual ID for specific morphological traits.
• Data is structured with clear variable definitions, such as viability measured per 40 larvae and wing length in millimeters.

Limitations

• The dataset is very small at 42.9 KB, indicating a limited experimental sample size with unknown row counts.
• Geographic origin of the flies or cactus is unspecified, limiting ecological generalizability.
• Data is static from a specific experiment, with no ongoing updates planned.
