Global warming resulting in increased temperature and precipitation and their effects on insect pests studied widely in separate function, but their interaction effects remained elusive. An interaction between temperatures and rainfall has a negative influence on incidence and growth rate of stem borer when temperature and rainfall are both high. Here, we speculate the joint effect of temperature and rainfall with a quadratic response unrevealed before suggests that outbreak risk of stem borer may unexpectedly be reduced. Global warming that reduced the population growth rate was elucidated mathematically, providing evidence of a new response of insect pests.
