摘　　要：[目的]寻求新的黄粉虫(Tenebrio molitor L.)饲料资源及紫红薯藤的开发利用途径。[方法]在室内研究了不同比例的紫红薯藤对黄粉虫半干物质中粗蛋白、粗脂肪、钙、磷、粗灰分的含量及黄粉虫体重的影响。[结果]与对照全麦麸相比,采用紫红薯藤饲喂黄粉虫有利于黄粉虫半干物质中粗灰分、钙含量的增加,但不利于老熟幼虫体重及粗脂肪的积累,且随着紫红薯藤添加量的增加呈逐渐降低趋势。与对照相比,当紫红薯藤的添加量为40%时有利于粗蛋白的积累,且达到显著水平;当紫红薯藤的添加量超过20%时磷含量呈逐渐降低趋势。[结论]适量添加紫红薯藤能促进黄粉虫体内粗蛋白、粗灰分、钙、磷的积累,但不利于黄粉虫幼虫体重的增加,并直接影响粗脂肪的积累。[ Objectivel To seek the new feed resources of Tenebrio molitor L. and the way of the development and utilization of purple sweet potato vine. [ Method] The crude protein, crude fat, Ca, P, crude ash, and weigh of Tenebrio rnolitor L. fed with different proportions of purple sweet potato vine were studied. [ Result] Compared with the control of whole wheat bran, feeding Tenebrio molito with purple sweet potato vine can increase the Ca and crude ash in the semi-dry matters of Tenebrio molitor, but goes against the accumulation of crude fat and weigh of Tenebrio molitor, and the content of crude ash and the weight of Tenebrio molitor were decreased gradually with the increasing addition of purple sweet potato vine. Compared with the control, 40% addition of purple sweet potato vine was beneficial to accumulation of crude protein. When the quantity of purple sweet potato vine was more than 20% , the phosphorus content was gradually decreased. [ Conclusion] The proper addition of purple sweet potato vine can increase the accumulation of crude protein, crude ash, Ca and P of Tenebrio molitor L. , but goes against the increase in body-weight of Tenebrio,and it will directly influence the accumulation of crude fat.
