Table 1_Rising of pyrethroid resistance mutations (kdr) in the dengue vector Aedes aegypti

Jessica V. Fay's dataset documents the evolution of knockdown resistance (kdr) mutations V1016I and F1534C in the dengue vector Aedes aegypti. The data, generated via TaqMan genotyping, compares samples from Posadas, Argentina, collected in 2019 and 2024. It shows a significant increase in kdr allele frequency, with 93% of 2024 samples carrying at least two resistance alleles.

Use Cases

• Tracking the temporal evolution of specific kdr mutations based on the described 5-year sampling period.
• Modeling the spread of pyrethroid resistance in mosquito populations based on the reported allele frequency changes.
• Assessing the correlation between insecticide use during dengue outbreaks and genetic resistance trends as suggested in the description.

Strengths

• Data covers two distinct time points (2019 and 2024) for longitudinal analysis.
• Provides specific mutation names (V1016I, F1534C) and quantifies allele frequency changes (>14% increase).
• Reports that 93% of samples in 2024 had at least two kdr alleles, indicating high resistance prevalence.

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 (14.9 KB), indicating limited scope.
