中文摘要：在自然变温条件下，对短翅豆芫菁Epicauta aptera Kaszab各虫态的发育历期、发育起点温度进行了研究。结果表明，短翅豆芫菁活动期各生长发育阶段历期多随温度的升高而缩短，发育速率则随温度的升高而加快；以1~4龄虫发育起点温度最低，卵的发育起点温度最高。
英文摘要：The developmental periods and developmental threshold temperatures (DTT) of Epicauta aptera Kaszab were studied under natural temperature conditions. The results show that the developmental periods of most developmental stages of E. aptera gradually shortened, and developmental rates gradually accelerated, with increasing temperature. The DTT of the lst-4th instars was the lowest and that of the egg was the highest.
