本研究的目的是制定特定年龄的生存和繁殖力的时间表，成人Plodia interpunctella（Hubner）相关的玉米储藏，特别是在美国东南部各州。用从南卡罗来纳州农场储存的玉米中收集的蛾建立实验室培养物，并在30 ℃和60% r.h.下保持在破碎的玉米上。在20、25、30和35 ℃和约75% r.h.条件下测定了存活率和繁殖力、产卵期长度、交配成功率和交配频率的特定时间表。最大产卵期在20和25 ℃时最长（18 d），在35 ℃时最短（8 d）。繁殖的最适温度（交配频率和繁殖力）为25-30 ℃，但平均寿命在20 ℃时最长（13.2d），并随温度的升高而线性下降。平均总（一生）生殖力范围从35 ℃时的16.9个卵到25 ℃时的227.7个卵。爱思唯尔有限公司出版
The purpose of this study was to develop age-specific survivorship and fecundity schedules for adult Plodia interpunctella (Hubner) relevant to maize storages, with special reference to the southeastern states (USA). Laboratory cultures were established with moths collected from farm-stored maize in South Carolina and maintained on cracked maize at 30 degrees C and 60% r.h. Age-specific schedules of survivorship and fecundity, the length of the oviposition period, mating success, and mating frequency were determined at 20, 25, 30, and 35 degrees C and about 75% r.h. The maximum oviposition period was longest (18 d) at 20 and 25 degrees C, and shortest (8 d) at 35 degrees C. The optimum temperatures for reproduction (mating frequency and fecundity) were 25-30 degrees C, but mean life-span was longest (13.2 d) at 20 degrees C and declined linearly with increasing temperature. Mean total (lifetime) fecundity ranged from 16.9 eggs at 35 degrees C to 227.7 eggs at 25 degrees C. Published by Elsevier Ltd.
