摘要：

【研究目的】黄粉虫为江苏吴江地区蔺草制品的主要仓储害虫之一，对其生物学特性研究为有效控制其危害具有重要意义。【方法】笔者采用有效积温法研究不同温度下黄粉虫的发育历期、发育速率、发育起点温度、有效积温。【结果】结果表明，温度对黄粉虫的影响为温度升高，各发育历期缩短，发育速率加快。蛹期发育起点温度最高，为11.8816℃，而卵期的发育起点温度最低，为8.0021℃。幼虫期有效积温最高，为67.6078℃?d。在24℃下，完成一个世代需要的时间为47.02天，而在28℃下，完成一个世代需要38.01天。【结论】因此，可以辅助利用低温或者高温处理蔺草制品控制黄粉虫的为害。

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.
