Abstract: 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.
