摘要
室内研究了饲料种类、饲养密度对黄粉虫幼虫生长速度、死亡率、化蛹率和虫体营养成分的影响.结果表明：（1）黄粉虫幼虫平均每头增重大小顺序为：C组（麦麸＋菜叶）＞ B组（麦麸）＞A组（白菜叶）＞D组（饥饿）,密度1～4头/cm^2的黄粉虫幼虫平均每头增重幅度大于6～8头/cm^2的处理组.（2）黄粉虫幼虫总死亡率的大小顺序分别为：A组、C组＞D组＞B组,8头/cm^2＞2～6头/cm^2＞1头/cm^2;自然死亡率的大小顺序分别为：B组、C组＞A组＞D组,8头/cm^2＞1～6头/cm^2;自相残杀死亡率的大小顺序分别为：A组、C组、D组＞B组,8头/cm^2＞4～6头/cm^2＞1～2头/cm^2;自相残杀死亡率占总死亡率比例的大小顺序分别为：D组＞A组、C组＞B组, 4～8头/cm^2＞2头/cm^2＞1头/cm^2.（3）黄粉虫幼虫化蛹率的大小顺序分别为：C组＞A、B、D组,1～2头/cm^2＞4头/cm^2＞6～8头/cm^2.（4）黄粉虫幼虫干物质含量的大小顺序分别为：B组＞ C组＞D组＞A组,8头/cm^2 ＞6头/cm^2＞1头/cm^2、4头/cm^2＞2头/cm^2;不同饲料条件下虫体中氮、磷含量的大小顺序为：D组、A组＞B组、C组;饲养密度对黄粉虫幼虫氮、磷含量均没有明显的影响.（5）在生产中,饲料以精饲料和青饲料合理搭配为宜,如果考虑化蛹繁殖,密度以2头/cm^2为宜;如果不考虑化蛹繁殖,则黄粉虫幼虫密度可以提高到4头/cm^2.
This paper focused on the larva growth rate, mortality, pupation rate, nutritional component of Tenebrio molitor L. at different fodders and breeding densities. They were evaluated in laboratory by the test of two factors （fodder and density） and muhi-levels. The results showed that： （ 1 ） The order of average body weight increase in mg/per larva of Tenebrio molitor respectively was： Group C （wheat bran ＋ Cabbage） 〉 Group B （wheat bran） 〉 Group A （Chinese cabbage） 〉 Group D （Starvation）, 1 ～ 4 larva/cm^2 〉 6 ～ 8 larva/cm^2. （2）The order of total larval mortality respectively was： Group A, Group C 〉 Group D 〉 Group B, 8 larva/cm^2 〉 2 ～ 6 larva/cm^2 〉 1 larva/cm^2 ;The order of natural mortality respectively was： Group B, Group C 〉 Group A 〉 Group D, 8 larva/cm^2 〉 1 ～ 6 larva/cm^2 ; The order of cannibalism mortality respectively was ： Group A, Group C, Group D 〉 Group B, 8 larva/cm^2 〉 4 ～ 6 larva/cm^2 〉 1 ～ 2 larva/cm^2 ; The order of the proportion of cannibalism mortality to total mortality respectively was： Group D 〉 Group A, Group C 〉 Group B, 4 ～ 8 larva/cm^2 〉 2 larva/cm^2 〉 1 larva/ cm^2. （3）The order of larva pupation rate of Tenebrio molitor respectively was： Group C 〉 Group A, Group B, Group D, 1 ～ 2 larva/cm^2 〉 4 larva/cm^2 〉 6 ～ 8 larva/cm^2 . （4） The order of larva dry matter content of Tenebrio molitor respectively was： Group B 〉 Group C 〉 Group D 〉 Group A, 8 larva/cm^2 〉 6 larva/cm^2 〉 1,4 larva/cm^2 〉 2 larva/cm^2 ; Larva nitrogen （ crude protein） content and phosphorus content of Tenebrio molitor were not affected by breeding densities while affected by fodders from high to low： Group A, Group D 〉 Group B, Group C. （5）It was appropriate to feed larva under the reasonable proportion of concentrated feed to succulence, and to culture larva at 2 larva/cm^2 if pupation and propagation were considered while at 4 larva/cm^2 if pupation and propagation were not considered in practice.
