Data from: Increase in crop losses to insect pests in a warming climate

Insect pests substantially reduce yields of three staple grains—rice, maize, and wheat—but models assessing the agricultural impacts of global warming rarely consider crop losses to insects. We use established relationships between temperature and the population growth and metabolic rates of insects to estimate how and where climate warming will augment losses of rice, maize, and wheat to insects. Global yield losses of these grains are projected to increase by 10 to 25% per degree of global mean surface warming. Crop losses will be most acute in areas where warming increases both population growth and metabolic rates of insects. These conditions are centered primarily in temperate regions, where most grain is produced.虫害会显著降低水稻、玉米、小麦这三大主粮的产量，但当前评估全球变暖农业影响的模型，极少将昆虫引发的作物损失纳入考量范畴。本研究依托已确立的温度与昆虫种群增长速率、代谢速率之间的关联关系，估算气候变暖将在何时、何地加剧昆虫对水稻、玉米、小麦造成的损失。据预测，全球平均地表温度每升高1摄氏度，这类主粮的全球总损失将增加10%至25%。作物损失最为严重的区域，将是变暖同时提升昆虫种群增长速率与代谢速率的地区。此类环境主要集中在温带区域，而全球绝大多数粮食均产自该地带。
