Abstract: The age specific, time specific life table of experimental population Liposcelis bostrychophila was established at 8 different temperatures (17.5~35℃), 5 different humidities (50~90%RH).The relations between population dynamics, temperature or humidity were discussed with Morris model, Weibull frequency distribution.The results indicated that the effect of temperature, humidity on survivorship was the most important factor to population trend index(I).Under suitable range of temperature, humidity,the population survival curve belonged to Deevey Ⅰ;while under improper conditions,it belonged to Deevey Ⅲ.Theoretically, finite increase rate (λ) had the highest value 1.0628 /day at 30.63℃.The optimum range of temperature, relative humidity for its development, reproduction was estimated at 28~30℃, 80%±RH, respectively.
