![]() xylostella is largely capable of tolerating future climates in most of the world and will remain a global pest beyond 2050. Using genome editing, a key gene, PxCad, emerged from our analysis as functionally temperature responsive. xylostella populations have high tolerance to projected future climates. By developing an eco-genetic index that combines genetic variation and physiological responses, we predict that most P. Here, we analyze genomic data from diamondback moth ( Plutella xylostella) collected from 75 sites spanning six continents to reveal that climate-associated adaptive variation exhibits a roughly latitudinal pattern. However, intraspecific variation of these responses arising from local adaptation remains ambiguous for most species. ![]() ![]() Understanding the genetic basis of climatic adaptation is essential for predicting species’ responses to climate change.
