We aim to discover impacts of climate changes, especially the extreme high events imbedded in the complicated natural changes of temperatures on insect pests and predators, and the underlying ecological and physiological mechanisms. We analyze and extracts the warming features in different seasons and regions based on historical dataset and simulate these features with > 30 programed climate chambers. We observe demographics and physiology in the lab and then verify findings with field data, and finally test the generality of findings with meta-analysis.
