摘　　要： 以中药材党参(Codonopsis pilosula)为寄主食料,在人工气候箱内,研究了温度对烟草甲(Lasioderma serricorne)卵、幼虫和蛹的生长和发育的影响;计算了烟草甲各虫态的发育起点温度和有效积温;通过Logistic模型及"王-兰-丁"模型对温度与烟草甲各虫态之间的关系进行拟合,优化拟合温度与烟草卵和幼虫发育关系的Logistic方程6个,温度与烟草甲幼虫发育关系的"王-兰-丁"方程5个。结果表明,烟草甲卵、幼虫、蛹及卵-蛹期的发育起点温度分别为16.51℃、11.07℃、11.78℃和12.20℃,其卵、幼虫、蛹及卵-蛹期的发育有效积温分别为89.59、669.53、137.12和912.72日度;温度的升高有利于烟草甲的各虫态的生长和发育;"王-兰-丁"模型拟合对研究较宽温度幅度的昆虫发育与温度之间的关系拟合效果优于Logistic模型。本研究结果可为危害储藏期中药材的烟草甲种群数量控制技术提供技术支撑。 Taking the Chinese medicinal herb Codonopsis pilosula as host feed,an incubation test was conducted to study the effects of temperature on the growth and development of Lasioderma serricorne （Coleoptera：Anobiidae）.The development threshold and effective accumulated temperature for the growth and development of L.serricorne were calculated,and the mathematical equations expressing the relationships between L.serricorne development and temperature were tested with Logistic model and ＂Wang-Lan-Ting＂ model.The development threshold temperature of L.serricorne at its egg,larva,pupae,and egg-pupae stages was 16.51,11.07,11.78,and 12.20℃,and the effective accumulated temperature was 89.59,669.53,137.12,and 912.72 day degree,respectively.Higher temperature was beneficial to the growth and development of L.serricorne.Comparing with Logistic model,the ＂Wang-Lan-Ting＂ model could better fit the relationships between L.serricorne development and temperature.This study supplied technical support to the pest control in the storage of C.pilosula.
