Overview

This research demonstrates the impact of temperature on local adaptation and transmission dynamics in Aedes aegypti populations, indicating a need for refined models.

Key Points

  • The aim is to investigate how phenotypic variation affects thermal performance in Aedes aegypti populations in relation to climate change.
  • Explored thermal performance of five field populations of Aedes aegypti from Mexico and one standard laboratory strain.
  • Reared populations at temperatures between 13°C and 37°C.
  • Generated thermal performance curves for various life-history traits.
  • Revealed significant phenotypic variation among populations affecting thermal performance.
  • Indicated local adaptation potential in Aedes aegypti populations.
  • Challenged the efficacy of 'one-size-fits-all' thermal performance models in predicting climate impact.
