摘　　要：[目的]降低饲养黄粉虫经济成本及提高玉米秸秆的利用率。[方法]在室内研究了不同比例的玉米秸秆对黄粉虫半干物质中体内粗蛋白、粗脂肪、Ca、P、干物质、粗灰分的含量及黄粉虫体重的影响。[结果]与对照全麦麸、纯精料相比,采用加入30%～60%玉米秸秆饲喂黄粉虫能极显著提高黄粉虫体内半干物质中的粗蛋白含量,但是不利于黄粉虫体重和体内粗脂肪的积累;其中配方V(50%玉米秸秆+50%精饲料)有利于干物质、粗灰分的积累;配方VII(70%玉米秸秆+30%精料)和配方VIII(70%光大发酵剂处理过的玉米秸秆+30%精料)有利于粗蛋白、Ca和P的积累;并且经不同方式处理后的玉米秸秆,对黄粉虫体内粗蛋白等营养指标的影响也存在着差异性。[结论]适量添加玉米秸秆能促进黄粉虫体内粗蛋白、粗灰分、干物质、Ca及P的积累,但是不利于黄粉虫生长及粗脂肪的积累。[Objective] The study aimed at reducing the economic cost of feeding Tenebrio molitor and improving the utilization ratio corn stalks.[Method] The effects of different proportions of corn stalks on the weigh of Tenebrio molitor and the contents of crude protein,crude fat,Ca,P,dry matter and crude ash in the half-dry matter of Tenebrio molitor had been studied in the laboratory.[Result] Compared with the recipes of all wheat bran and pure fine fodder,feeding Tenebrio molitor by applying 30%-60% of corn stalks could significantly improve the content of crude protein in the half-dry materials of Tenebrio molitor,but it was detrimental to the improvement in weight of Tenebrio molitor and the accumulation of crude fat.To be specific,the recipe V（50% of corn stalks ＋ 50% of fine fodder） was beneficial to the accumulation of dry matter and crude ash.The recipe VII（70% of corn stalks ＋ 30% of fine fodder） and the recipe VIII（70% of corn stalks treated with Guangda feed leaven ＋ 30% fine fodder） were beneficial to the accumulation of crude protein,Ca and P.There were differences among the influences of corn stalks in different treatments on the crude protein and other nutrition indicators of Tenebrio molitor.[Conclusion] Appropriately applying corn stalks can improve the accumulation of the crude protein,crude ash,dry matter,Ca and P of Tenebrio molitor but was detrimental to the growth and development of Tenebrio molitor and the accumulation of crude fat.
