Sitophilus Zeamais Volatile Emissions Under Thermal Stress Across Three Strains

Three strains of the maize weevil Sitophilus zeamais, originating from Kansas and Brazil, were reared under controlled temperatures. Volatile emissions from cohorts of 10 male and 10 female weevils were profiled using solid-phase microextraction and gas chromatography-mass spectrometry. The dataset, uploaded by MATTHEW HETHERINGTON to figshare, was last updated in May 2026.

Use Cases

• Modeling the effect of thermal stress on insect volatile emissions based on the described experimental design.
• Comparing chemical communication robustness across geographically distinct insect strains as described.
• Analyzing the relationship between rearing temperature and specific pheromone (sitophilure) quantification mentioned in the description.

Strengths

• Data originates from a controlled factorial experiment with three temperature treatments and three insect strains.
• Volatile profiling was conducted using standardized methods (SPME and GC-MS) as described.
• Dataset is openly available under a CC0-1.0 license.

Limitations

• The dataset is very small at 37.3 KB, indicating limited scope.
• Row count and column-level documentation are unknown, which may limit suitability assessment.
• Data may reflect geographic bias inherent to the specific sampled populations.
