Abstract:

[OBJECTIVE] Tenebrio molitor L. is one of the main storage pests of rush products in Wujiang, Jiangsu city and there is great means to study on the biological characteristics for effectively controlling the hazards. [METHOD]Different temperatures of the developmental period, developmental rate, developmental threshold temperature, effective accumulated temperature of T. molitor were studied with effective temperature method . [RESULTS]Results indicated that the effects of temperature on T. molitor were that the temperature was higher and the developmental durations was shorter and growth rate accelerated. Pupal stage developmental threshold temperature of the highest, 11.8816 ℃, while the egg stage of the developmental threshold temperature of the lowest, 8.0021 ℃.The larval stage the maximum effective temperature for the 67.6078 ℃?d. T. molitor finished a generation with 47.02 days in 24 ℃. However, 38.01 days were needed to finished a generation in 28 ℃. [CONCLUSION] So the damage of T. molitor for rush products could be controlled effectively with low or high temperature treatment.
