Abstract Ephestia kuehniella Zeller, is a major pest in stored products, and a host resurgence for rear natural enemies. Understanding the relation between temperature variations and the life table parameters of E. kuheniella is necessary to predicting its population dynamics and improve the efficiency of mass rearing through determining the optimal temperature. The influence of seven temperatures (15, 17.5, 20, 22.5, 25, 27.5 and 30 °C) on the development, reproduction and survival of E. kuehniella were tested under laboratory conditions. Development time of almost all immature stages in E. kuheniella was the shortest at temperatures of 30, while the longevity of male and female decreased with increasing temperatures. At 27.5 °C E. kuheniella females had the highest intrinsic rate of natural increase (0.07111 d−1), and finite rate of increase (1.077 d−1). All demographic parameters showed a parabolic relation with temperature. The consequences of the present research showed that the temperatures between 25 °C to 27 °C, were most favorable for the reproduction and development of E. kuheniella and that for mass rearing in this species and predict E. kuheniella population phenology and dynamics.

Ephestai kuheniella (Lep: Pyrallidae) 在不同恒温条件下的年龄阶段、两性生命表

摘要 Ephestia kuehniella Zeller是储藏产品中的主要害虫，是后方天敌的寄主回潮。了解温度变化与 E. kuheniella 生命表参数之间的关系对于预测其种群动态和通过确定最佳温度提高大规模饲养效率是必要的。在实验室条件下测试了七种温度（15、17.5、20、22.5、25、27.5 和 30 °C）对 E. kuehniella 发育、繁殖和存活的影响。E. kuheniella几乎所有未成熟阶段的发育时间在30℃时最短，而雄性和雌性的寿命随着温度的升高而缩短。在 27.5 °C 时，E. kuheniella 雌性具有最高的内在自然增长率 (0.07111 d-1) 和有限增长率 (1. 077 d-1)。所有人口统计参数都显示出与温度的抛物线关系。本研究的结果表明，25 °C 至 27 °C 之间的温度最有利于 E. kuheniella 的繁殖和发育以及该物种的大规模饲养，并预测 E. kuheniella 种群物候和动态。
